An event is a procedure of the framework engine that informs you that a certain process occurred, and consequently allows you to capture this event and add your own code. The ApplinX events are called by the ApplinX framework building blocks.
Occurs before gx_connect, gx_attach.
Use event.isNewSession() to ascertain if it is before
attach or connect.
Use event.getSessionConfig() to change the connection to
the ApplinX server parameters.
Capture the event for the whole project from
GXBasicContext, or from a certain page, in
YOUR_PAGE.java, OnInit function.
For example, adding a device name:
}
public void gx_preConnect(GXIHostPageContext gx_context,GXPreConnectEvent event){
if (event.isNewSession()){
event.getSessionConfig().addVariable(GXBaseObjectConstants.GX_VAR_DEVICE_NAME,"MY_DEVICE"));
}
}
Use e.newSession to ascertain if it is before attach or
connect.
Use e.sessionConfig to change the connection to the
ApplinX server parameters.
Capture the event for the whole project from
GXBasicWebForm, or from a certain page, in
YOUR_PAGE.aspx.cs, OnInit function.
For example, adding a device name:
protected override void OnInit(EventArgs e){
base.OnInit(e);
this.gx_preConnect += new GXPreConnectEventHandler(user_preConnect);
...
}
protected void user_preConnect(object sender,GXPreConnectEventArgs e){
if (e.newSession){
e.sessionConfig.Variables = new GXVariable[] {new GXVariable(com.sabratec.applinx.baseobject.GXBaseObjectConstants.GX_VAR_DEVICE_NAME,"MY_DEVICE")};
}
}
Occurs after gx_connect, gx_attach.
Use event.isNewSession() to ascertain if it is after
attach or connect.
For example, skip messages screen, for all the project pages (in
GXBasicContext):
public void gx_postConnect(GXIHostPageContext gx_context,GXPostConnectEvent event){
if(gx_context.getGXSession().getScreen().getName().equals("MESSAGE_SCREEN")){
gx_context.getGXSession().executePath("SKIP_MESSAGES_PATH");
}
}
Use e.newSession to ascertain if it is after attach or
connect.
For example, skip messages screen, for all the project pages (in
GXBasicWebForm):
protected override void OnInit(EventArgs e){
base.OnInit(e);
this.gx_postConnect += new GXPostConnectEventHandler(user_postConnect);
...
}
protected void user_postConnect(object sender,GXPostConnectEventArgs e){
if (gx_session.getScreen().getName() == "MESSAGE_SCREEN"){
gx_session.executePath("SKIP_MESSAGES_PATH");
}
}
Occurs before gx_processHostKeyRequest(GXSendKeysRequest
sendKeyRequest), which is activated from a browser PF key, if ENTER is
pressed, or JavaScript command gx_SubmitKey(key).
Use event.getSendKeyRequest to change the send key
request to the ApplinX server.
For example:
public void gx_preSendKeys(GXIHostPageContext gx_context,GXPreSendKeyEvent event){
if(event.getSendKeyRequest().getKeys().equals("[enter]")){
event.getSendKeyRequest().setKeys("[pf3]");
}
}
Use e.sendKeyRequest to change the send key request to
the ApplinX server.
For example:
protected override void OnInit(EventArgs e){
base.OnInit(e);
this.gx_preSendKeys += new GXPreSendKeyEventHandler(user_preSendKeys);
...
}
protected void user_preSendKeys(object sender,GXPreSendKeyEventArgs e){
if (e.sendKeyRequest.getKeys() == "[enter]"){
e.sendKeyRequest.setKeys("[pf3]");
}
}
Occurs after gx_processHostKeyRequest(GXSendKeysRequest
sendKeyRequest), which is activated from a browser PF key, if [ENTER] is
pressed, or a JavaScript command gx_SubmitKey(key).
// used for performing actions after send keys
public void gx_postSendKey(GXIHostPageContext gx_context,GXPostSendKeyEvent event)throws GXGeneralException{
if (gx_context.getGXSession().getScreen().getName().equals( "DisplayMessage")){
getGXSession().sendKeys("[enter]");
}
}
protected override void OnInit(EventArgs e){
base.OnInit(e);
this.gx_postSendKeys += new GXPostSendKeyEventHandler(user_postSendKeys);
...
}
protected void user_postSendKeys(object sender,GXPostSendKeyEventArgs e){
if (gx_session.getScreen().getName() == "DisplayMessage"){
gx_session.sendKeys("[enter]");
}
}
Occurs if the form sequence screen number is different from the
gx_session sequence screen number.
Use event.setSendToHost to send the data to the host in
any case.
For example:
public void gx_screenSeqMismatch(GXIHostPageContext gx_context,GXScreenSeqMismatchEvent event){
if (gx_context.gx_getForm(gx_context.getGXSession().getScreen().getName()).equals(gx_context.getGXForm().getFormName()){
event.setSendToHost(true);
}
}
Use e.sendToHost to send the data to the host.
For example:
protected override void OnInit(EventArgs e){
base.OnInit(e);
this.gx_screenSeqMismatch += new GXIScreenSeqMismatchEventHandler(user_screenSeqMismatch);
}
protected void user_screenSeqMismatch(object sender,GXIScreenSeqMismatchEventArgs e){
if (gx_getForm(gx_session.getScreen().getName()) == gx_form.FormName){
e.sendToHost = true;
}
}
Occurs before loading next page, by
gx_handleHostResponse. Use e.nextForm to change the
next page.
For example:
public void gx_changeNextForm(GXIHostPageContext gx_context,GXChangeNextFormEvent event)throws GXGeneralException{
if (gx_context.getGXSession().getScreen().getName.equals("SCREEN_A")){
event.setNextForm("SCREEN_B.jsp");
}
}
protected override void OnInit(EventArgs e){
this.gx_changeNextForm += new GXChangeNextFormEventHandler(user_changeNextForm);
}
protected void user_changeNextForm(object sender,GXChangeNextFormEventArgs e){
if (gx_session.getScreen().getName == "SCREEN_A"){
e.nextForm = "SCREEN_B.aspx";
}
}
Occurs before gx_syncHostWithForm, and its use is to add
parameters to the map path that is executed by the framework. The map path in
the framework is declared in:
JSP: GXBasicContext : gx_appConfig.setMapPath("<APPLINX MAP
PATH NAME>");
.NET : GXBasicWebForm : gx_appConfig.MapPath = "<APPLINX MAP
PATH NAME>"
For example:
public void gx_preSyncHostWithForm(GXIHostPageContext gx_context,GXPreSyncHostWithFormEvent event)throws GXGeneralException{
event.getNavigateRequest().addVariable("CUSTOMER_ID", gx_context.getRequest().getparameter("CUSTOMER_ID"));
}
protected override void OnInit(EventArgs e){
this.gx_preSyncHostWithForm +=new GXPreSyncHostWithFormEventHandler(user_preSyncHostWithForm);
}
protected void user_preSyncHostWithForm(object sender,GXPreSyncHostWithFormEventArgs e){
e.navigateRequest.addVariable("CUSTOMER_ID", Request.QueryString["CUSTOMER_ID"];
}
Occurs before gx_fillForm() or
gx_fillForm(GXIScreensCollection screen).
Use this user exit to fill in additional fields whose contents are not received directly from the current host screen.
For example:
public void gx_preFillForm(GXIHostPageContext gx_context)throws GXGeneralException{
gx_context.getTagsAccesor().setTagContent("UserNameTitle",gx_context.getSession.getAttribute("UserName"));
}
protected override void OnInit(EventArgs e){
this.gx_preFillForm +=new EventHandler(user_preFillForm);
}
protected void user_preFillForm(object sender,EventArgs e){
UserNameTitle.Text = Session["UserName"];
}
Occurs after gx_fillForm() or
gx_fillForm(GXIScreenCollection screens). Use this user exit to
override the field data received from the host screen.
For example
public void gx_postFillForm(GXIHostPageContext gx_context)throws GXGeneralException{
gx_context.getTagsAccesor().setTagContent("CustomerID",gx_context.getSession.getAttribute("CustomerID"));
}
protected override void OnInit(EventArgs e){
this.gx_postFillForm +=new EventHandler(user_postFillForm);
}
protected void user_postFillForm(object sender,EventArgs e){
CustomerID.Text = Session["CustomerID"];
}
Use this user exit to manipulate the content of a Natural downloaded file and change the content to formats such as RTF, CSV or to any other desired format.
For example
In GXBasicContext:
public void gx_downloadFile(String fileName, byte[] bytes) throws IOException {
String fileContent = new String(bytes); // create a string from the bytes
// manipulate here the fileContent
super.gx_downloadFile(fileName, fileContent.getBytes()); // call super to continue with the download.
}
In GXBasicWebForm:
Visual Basic
Public Overrides Sub gx_downloadFile(ByVal fileName As String, ByVal bytes As Byte())
Dim encoding As New System.Text.ASCIIEncoding '' create a bytes to string ASCII converter
Dim fileContent As String = encoding.GetString(bytes) '' convert the bytes into String
'' manipulate here the fileContent
MyBase.gx_downloadFile(fileName, encoding.GetBytes(fileContent)) '' call base method to continue with the download.
End Sub
C#
public override void gx_downloadFile(string fileName, byte[] bytes)
{
System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding(); // create a bytes to string ASCII converter
string fileContent = encoding.GetString(bytes); // convert the bytes into String
// manipulate here the fileContent
base.gx_downloadFile(fileName, encoding.GetBytes(fileContent)); // call base method to continue with the download.
}
Use this user exit to manipulate/modify the name of a downloaded Natural file.
For example:
In GXBasicContext:
@Override
public String gx_getNdtDefaultDownloadFileName(String fileName, String workingFile) {
if("D5".equals(workingFile)){
return "NewFileName.txt";
}
return super.gx_getNdtDefaultDownloadFileName(fileName, workingFile);
}
Visual Basic
Public Overrides Function gx_getNdtDefaultDownloadFileName(ByVal fileName As String, ByVal workingFile As String) As String
If ("D7".Equals(workingFile)) Then
Return "C:\\temp\\NewFileName.csv"
Else
Return MyBase.gx_getNdtDefaultDownloadFileName(fileName, workingFile)
End If
End Function
C#
public override string gx_getNdtDefaultDownloadFileName(string fileName, string workingFile)
{
if ("D7".Equals(workingFile))
{
return "C:\\temp\\NewFileName.csv";
}
return base.gx_getNdtDefaultDownloadFileName(fileName, workingFile);
}
Method gx_isSupportedFeature indicates
whether a particular feature is supported by the browser. Currently the only
supported feature IDs are:
html.inputtypes.date for the HTML5 calendar
feature
html.inputtypes.month for the HTML5
calendar feature with month format
browser.window.support for modal window
support on mobile devices
Additionally, a tag is available under Java and .NET to determine whether a feature is supported. Sample code for calling the method and examples of using the tag are given below.
Method example:
try {
boolean isSup = gx_isBrowserSupportingFeature(GXIBrowserSupportedFeatures.HTML_INPUT_TYPE_DATE);
} catch (GXUnsupportedFeatureException e) {
GXLog.debug(this, "Feature detection not already initialized...");
}
Tag example:
<gx:isFeatureSupported id="html.inputtypes.date" attributeName="dateSupported"/>
<%
Boolean feature = (Boolean)request.getAttribute("dateSupported");
if (feature != null ){
out.print("Browser is supporting feature 'html.inputtypes.date' : "+ feature);
} else {
out.print("Feature detection not already initialized...");
}
%>
or more simply:
<%=dateSupported %>
Visual Basic
Method example:
Try
Dim sup As Boolean
sup = gx_isBrowserSupportingFeature("html.inputtypes.date")
Catch ex As Exception
GXLog.debug(Me.GetType(), "Feature detection not already initialized...")
End Try
Tag example:
<%@ Register Assembly="GXDotnet" Namespace="com.sabratec.dotnet.framework.web.controls" TagPrefix="gx" %>
<gx:GXIsFeatureSupported runat="server" featureID="html.inputtypes.date" attributeName="isSupportDateHTML5" />
<%
Dim res
res = HttpContext.Current.Items("isSupportDateHTML5");
if res IsNothing Then
Dim feature As Boolean
feature = CType(res,Boolean)
Response.Write("Browser is supporting feature 'html.inputtypes.date' : "& feature)
Else
Response.Write("Feature detection not correctly initialized...")
End If
%>
or more simply:
<%=dateSupported %>
C#
Method example:
try
{
bool b = gx_isSupportedFeature("html.inputtypes.date");
}
catch (Exception ex)
{
GXLog.debug(this.GetType(), "Feature detection not already initialized...");
}
Tag example:
<%@ Register Assembly="GXDotnet" Namespace="com.sabratec.dotnet.framework.web.controls" TagPrefix="gx" %>
<gx:GXIsFeatureSupported runat="server" featureID="html.inputtypes.date" attributeName="isSupportDateHTML5" />

Boolean feature = (Boolean) HttpContext.Current.Items["isSupportDateHTML5"];
if (feature != null ){
Response.Write("Browser is supporting feature 'html.inputtypes.date' : "+ feature);
} else {
Response.Write("Feature detection not correctly initialized...");
}
%>
Or more simply:
<%= HttpContext.Current.Items["isSupportDateHTML5"]%>
GXIClientBaseObject(getGXSession)
Package:com.sabratec.applinx.baseobject The new ApplinX
base object. See Base Object
documentation.
GXIClientBaseObject (gx_session)
Namespace: com.sabratec.applinx.baseobject
GXScreenBasedJspContext
Package: com.sabratec.applinx.j2ee.framework.web
ApplinX API context class, which your project context classes extend from, contains the required logic for ApplinX framework.
GXScreenBasedWebForm
Namespace: com.sabratec.dotnet.framework.web
ApplinX ASP.NET API page, which your project pages inherits from, contains the required logic for ApplinX framework.
Use this function to attach to a session based on
getGXAppConfig().getSessionConfig()
(JSP)/gx_appConfig.SessionConfig (.NET) declarations. If
the user is already attached (from the previous page), it will use the same
session.
This function is called automatically when inheriting from GXDefaultLogicContext(JSP)/GXDefaultLogicWebForm(.NET) .
Note:
It is not necessary to detach as this is done automatically by the
framework.
Use this function to connect to a session based on
getGXAppConfig().getSessionConfig()
(JSP)/gx_appConfig.SessionConfig (.NET) declarations.
gxfirstpage.java
(JSP)/gxfirstpage.aspx.cs(vb) (.NET) is the class that activates
this function by default.
Use this function to disconnect a session based on
getGXAppConfig().getSessionConfig()
(JSP)/gx_appConfig.SessionConfig (.NET) declarations.
logoff.java (JSP)/logoff.aspx.cs(vb) (.NET)
is the class that activates this function by default.
This function calls gx_fillTables and
gx_fillFormFields. Called when the page is loaded automatically
when inheriting from
GXDefaultLogicContext(JSP)/GXDefaultLogicWebForm
(.NET). This function is called when staying in the same screen after
sending keys, when calling gx_handleHostResponse.
Uses the values of the application fields in the screens of the path response to fill the page.
For example:
GXPathResponse res =getGXSession().executePath("collect_customer_data");
gx_fillForm(res.getScreens());
GXPathResponse res =gx_session.executePath("collect_customer_data");
gx_fillForm(res.getScreens());
This function is called automatically by gx_fillForm. It
fills the page with values from the current screen. The decision, which fields
to update, is determined by getGXAppConfig().getFieldTypesInUse()
(JSP) /gx_appConfig.FieldTypesInUse() (.NET) .
In JSP, this function is called automatically by
gx_fillForm. It will automatically call the
getTagsAccessor().setTagTable method. It can be overridden in
order to customize the table created to be based on a path, or to add user
events.
In .NET, this function is called automatically by
gx_fillForm. It checks if a control with the same ID as the
ApplinX table is related to the current screen. If this control is an HTML
table, it will automatically call the GXTablesHandler
fillHtmlTableFromGXTable method. If the control is a DataGrid it will
convert the host table into a DataTable object and bind it to the DataGrid. It
can be overridden in order to customize the table created to be based on a
path, or to add user events.
This function is called to synchronize between the Web application
screen to the host screen. This function calls gx_fillForm when
the screen/page was not changed, otherwise redirects to the matching page for
the new host screen.
This function loads the default ApplinX error page
gx_appConfig.getErrorForm. It can be overridden to change error
handling.
This function checks to see whether the current page matches the current host screen (this function is not relevant for Instant pages). When they do not match, the framework redirects to the matching page. Use this if you want your application to work in the traditional host oriented approach.
This function checks to see whether the host matches the current page
screen (this function is not relevant for Instant pages). When they do not
match, the framework calls the map declared in
getGXAppConfig().getMapName()
(JSP)/gx_AppConfig.MapName (.NET) , and executes it in
order to navigate to the matching host screen. Use this if you want your
application to work in a Web oriented approach, that is, the Web application
decides what page to load (by links), and not the host.
This feature handles Web-host synchronization, and allows the ApplinX Web application to support the Back button in the browser. To implement this, it is necessary to include all the screens that are in your new Web application in the Map path.
Returns GXSendKeysRequest object, with the string keys
typed as the argument values. Use this function to retrieve from the current
page a GXSendKeyRequest object with all the fields from the page,
and the current position of the cursor. For example, when you add a server-side
button that is intended to send all fields followed by the [ENTER] key:
getGXSession().sendKeys(gx_prepareSendKeysRequest("[enter]"));
gx_session.sendKeys(gx_prepareSendKeysRequest("[enter]"));
Returns GXPathRequest object with the
pathName. Use this function to retrieve from the current page a
GXPathRequest object with all the fields from the page. For
example, when you add a server-side button that is intended to execute a path
with all fields from the current screen and execute the path:
getGXSession().executePath(gx_preparePathRequest("path_login"));
gx_session.executePath(gx_preparePathRequest("path_login"));
Use this function when working with server side buttons and needing to perform a simple PF key action, or a PF key action with cursor focusing. Perform the entire process of sendKeys and navigate to the next page.
GXCursor is in the package
com.sabratec.applinx.baseobject.
Use this function when working within a page that contains an HTML table control/tag which is bound to an ApplinX host table, and you need to perform a simple row selection action in a server-side click event.
This function performs the following process of selecting a host row in a screen that contains a host table: sends all the screen fields, selects a row in the action field (actionField), with the action value ("X", "1" etc.) and navigates to the next page.
Use the first function (gx_doSelectRowLogic(actionField))
when the selection column is cursor-sensitive and there is no need to place an
action value in it.
Use the second function (gx_doSelectRowLogic(actionField,
actionValue)) when an action value is required.
Use the third function (gx_doSelectRowLogic(actionField,
actionValue, actionKey)) when the action key is not the [ENTER] key.
This function is called for each field in the screen when
gx_fillForm is called.
This function can be overridden to affect the look-and-feel of a gx tag according to the data in the host field.
For example:
public void gx_setField(String tagId,GXIField field){
super.gx_setField(); the default behavior
if (!field. IsVisible()){
getTagsAccesor().setTagVisible(tagId,false);
}
}
This function can be overridden to affect the look-and-feel of a control according to the data in the host field.
For example:
public override void gx_setField(Control ctrl,GXIField field){
base.gx_setField(Control ctrl, GXIField field); the default behavior
if (!field. IsVisible())
ctrl.Visible = false;
}
}
Returns boolean.
Determines if a page exists, so that the engine can redirect to that page.
Returns string.
The name of the next form to load according to the current host
screen. Can be SCREEN_NAME.jsp or instant.jsp for JSP
and SCREEN_NAME.aspx or instant.aspx for .NET.
Loads the given form. Keeps the host session open when redirecting to the target form.
Uses response sendRedirect.
Uses response redirect.
Returns boolean.
Indicates whether the host screen name matches the current page name.
Returns string.
Returns the matching page for a given host screen.
By default it is <SCREEN_NAME>.jsp. Can be
overridable to send a few host screens to the same page.
For example:
public gx_getForm(String screenName){
If ( screenName.equals("SCREEN_A") || screenName.equals("SCREEN_B"){
return "PAGE_A.jsp";
}
return super.gx_getForm(screenName); // for default
}
By default it is SCREEN_NAME.aspx. Can be overridable to
send a few host screens to the same page.
For example:
Protected override gx_getForm (String screenName){
If (screenName == "SCREEN_A" || screenName == "SCREEN_B"){
Return "PAGE_A.aspx";
}
return base. gx_getForm (screenName); // for default
}
This function is activated from a browser PF key or when [ENTER] is
pressed, or javascript:gx_SubmitKey(key).
gx_processHostKeyRequest(GXSendKeysRequest sendKeyRequest)
Executes the given send keys request, and throws the relevant event:
gx_preSendKey
gx_postSendKey
This function can be overridden in order to use customized code with the relevant action key.
Properly closes the current host window. Use this function when a
pop-up window is closed by the user, in the gx_closeWindow event.
Accept a parameter of a host key to send to the host in order to close the host
window.
(gx_form - .NET )
(getGXForm() - JSP)
Package: com.sabratec.applinx.framework
The ApplinX.NET and JSP pages are handled as the interface
GXIScreenBasedForm. This interface is passed to the framework
engine in order to fill the fields, read the fields values and get form
details. All the interface methods are overridable and can be used to customize
the page fields' update and returned values.
Returns to the host (from the page) the value of an AppField.
Returns to the host (from the page) the value of a host field by position.
Returns to the host (from the page) the value of a multiple AppField.
Only the relevant methods will be called according to the value of
gx_appConfig.
Sets the value of a page field from an AppField.
Sets the value of a page field from a host field.
Sets the value of a page field from AppField, overridable. The calls
for the three functions depend on a call to gx_fillForm, and the
value of gx_appConfig.getFieldTypesInUse().
Returns the page sequential screen number.
Returns the name of the field that is focused on, in the page.
Returns the current page name.
Returns the PF key pressed in the browser.
Use the following control to display the ApplinX instant HTML page. The
Instant component is included in instant.aspx/jsp and in a
generated page for a screen group. Refer to the Instant API Javadoc in the ApplinX API Specification.
The instant configuration may be modified within the
framework in the class GXInstantLogicContext (JSP)/
GXInstantLogicWebForm (.NET). For the configuration options see
the class com.sabratec.applinx.presentation.GXRenderConfig in the
ApplinX Development API Javadoc.
The Host Keys custom tag allows developers to control the dynamic host
keys collection in various common options and custom templates. This control
allows creating complex UI, based on the host keys, without any code. This
component is useful for creating a fast, advanced UI in a Web enabling
application by combining it anywhere in the framework template. The host keys
collection is rendered inside a container which may be a standard HTML table.
This component can be fully customized using the GXIHostKeysTagUserExit
interface. Refer to
Customizing the
Host Keys.
The custom tag contains the following attributes:
May be Links, Buttons or Template.
Determines the way each host will be displayed. When defined to be
displayed as Template, the tag's inner HTML should contain the HTML text that
will be rendered for each host key. The HTML text may contain the tokens:
$(ACTION) and $(CAPTION) for dynamic replacements.
Action being the name of the function key itself, that will be sent to the host
(for example - [ENTER], [PF5], [PA2]) and Caption, the text associated with the
function key (written below or next to the function key name).
Determines the css class of the rendered HTML for the host keys.
Determines how the host keys are displayed.
Possible values: true, false. When set to
false, the host keys will be displayed horizontally.
In order to control the HTML table container of the host keys, all
the standard HTML table attributes are supported: width,
height, cellspacing, cellpadding and
border.
Example of use:
Render the host keys vertically, as a custom tag in
beforemainpane.
For example:
<gx_host:hostKeys vertical="true" keyType="Template" cssClass="blueButton">
<a href="#" onclick="gx_SubmitKey('$(ACTION)')" title="$(CAPTION)">
<img src="images/$(ACTION).gif">
</a>
</gx_host:hostKeys>
<gx:GXHostKeysControl runat="server" vertical="true" keyType="Template" Class="blueButton">
<a href="#" onclick="gx_SubmitKey('$(ACTION)')" title="$(CAPTION)">
<img src="images/$(ACTION).gif">
</a>
</gx:GXHostKeysControl>
This control generates a java applet tag for the ApplinX printlet. Refer to the ApplinX Printer Applet. Included within the run_printlet.aspx file.
Occurs before a page is posted back to the server side. Can be triggered from both a server side button or keyboard PF key/ENTER. Add it to the relevant page in order to carry out validation checks.
For example:
<script>
function user_prePostBack(){
if (isValid()){ // isValid() is a user function that checks validity
return false;
}
return true;
}
<script>
Used for submitting the page and activating the specified function in the associated context class. The specified function should be a public function with no parameter and no return value.

Occurs when each new table cell TD with run-time data is created. Allows you to customize the table data TD according to the current host row.
Occurs when each new control inside a TD with run-time data is created. Allows you to customize the controls according to the current host row.
NameSpace: com.sabratec.dotnet.framework.web.tables
Interface for events when the HTML table rows are duplicated with run-time
data.
Methods:
Occurs when new table rows (TR) with run-time data, are created. Allows you to customize the TR according to the current host row.
Occurs when each new table cell TD with run-time data is created. Allows you to customize the table data TD according to the current host row.
Occurs when each new control inside a TD with run-time data is created. Allows you to customize the controls according to the current host row.
Example:
'' in the code behind of the designed table web page
public override void gx_fillTable()
{
GXTablesHandler.fillHtmlTableFromGXTable(CustomerReportHtmlTable, gx_session.getTables()[0], this);
}
public void gx_changeControl(int colIndex,HtmlTableCell td, Control ctrl, GXITableRow row){
// a link inside a TD will get its value from the Subject // // column
if (ctrl is HtmlAnchor){
((HtmlAnchor)ctrl).InnerHtml = row.getItemContent("Subject");
}
}
public void gx_changeTd(int colIndex,HtmlTableCell td,GXITableRow row) {
// a table with a red host row will get a marked row css class.
if ( ((GXFieldTableCell)row.getItem("Subject")).getFGColor() == GXBaseObjectConstants.GX_FIELD_COLOR_LIGHT_RED){
td.Attributes["class"] = "marked_row";
}
}
public void gx_changeTr(int rowIndex, HtmlTableRow tr, GXITableRow row){
// a row with dashed in the Subject field will be disabled
if (row.getItemContent("Subject").IndexOf("----") > -1){
tr.Visible = false;
}
}
JSP:
GXIWindow (getGXWindow() )
Package: com.sabratec.applinx.framework.web.windows
.NET:
GXIWindow (gx_window).
Namespace: com.sabratec.applinx.framework.web.windows
Loads the given page name in the current window, or its opener. The loading is done inside the frameset.
Loads the given page name in the current window, or its opener. The loading is done outside the frameset.
Closes the referred window(gx_window or gx_window.opener).
Note:
When performing a set of actions, ensure this method is the last
one, because any line after it will not be executed.
Opens the specified page name, with the given width and height.
Allows you to add a JavaScript function to be executed.
Allows you to resize the window (for example, if the host window was changed).
Calls the server-side gx_refreshWindow(GXBasicContext)(JSP)/gx_refreshWindow(in GXBasicWebForm) (.NET) event, which can be used to update the form field.
By default when a window is closed, the opener is refreshed (Good for
instant). You can cancel this behavior in specific functions by calling:
gx_window.opener.cancelRefresh()
Allows you to return a field from the pop-up window to the main window using server or client-side code.
If true, means that the current window is a main window.
If true, means that the current window is a pop-up window.
Allows you to position the window (for example, if the host window was changed).
When activating the pop-up manager, there are various configurations that the developer can configure. These can be configured in the Framework Editor, Window node.
The pop-up manager is based on a frameset, one frame is always visible
and the other isn't. In the development stage the developer may want to make
the invisible frame also be visible. A typical case may be for a design time
error that is not shown. To make the invisible frame visible, you are required
to change the size of the frame columns in
config/gx_clientConfig.xml engineConfig parameters,
defaultFrameColumns="100%", change 100% to a different suitable number.
The following user exits will be called only when the pop-up window manager is activated:
Occurs prior to a pop-up window display, which is opened by the framework before a host window's appearance. Used for controlling if and how to open the pop-up window.
Use event.setWidth (jsp), event.setHeight to control the
size of the opened window.
Use event.setPosX(jsp), event.setPosY(jsp) to control the
position of the opened window.
Use event.setLoadAsWindow(false) to cancel the opening of
the pop-up window (will be opened as a main page).
Use e.Width, e.Height to control the size of the opened
window.
Use e.PosX, e.PosY to control the position of the opened
window.
Use e.LoadAsWindow = false to cancel the opening of the
pop-up window (will be opened as a main page).
Occurs in the main window page whenever the user closes a pop-up
window using the X button. Allows the developer to update the page when this
event occurs. By default, calls gx_fillForm.
Occurs in the pop-up window page whenever the user closes a pop-up
window using the X button. Allows the developer to send an exit key (PF3 for
example) to the host so that the Web application will be synchronized with the
host application. Typical usage: gx_doCloseWindow("[PF3]").
