ICON

The ICON control is similar to the BUTTON control, but it uses an image to display its function. When chosen, it calls a method in the adapter class.

The following topics are covered below:


Example

graphics/image077.png

The XML layout definition is:

<rowarea name="Icons">
    <itr>
        <icon image="../HTMLBasedGUI/images/remove.gif" method="remove" title="Remove">
        </icon>
        <icon image="../HTMLBasedGUI/images/cut.gif" method="cut" withdistance="true"
              title="Cut">
        </icon>
        <icon image="../HTMLBasedGUI/images/paste.gif" method="paste" title="Paste">
        </icon>
    </itr>
</rowarea>

Hiding and Disabling Icons

As with many other controls, the icon provides an invisibleprop property that may point to an adapter property that decides whether to display an icon ("true") or not ("false"). By using the property imageinactive, you can fine-control the icon's behavior in the following way:

Consequence: if you want to show grayed images for inactive icons, then use imageinactive.

Properties

Basic
image

URL that points to the image that is shown as icon.

The URL either is an absolute URL or a relative URL. If using a relative URL then be aware of that the generated page is located directly inside your project's directory.

Example: "images/icon.gif" points to an icon in an images-folder that is parallel to the page itself. "../HTMLBasedGUI/images/new.gif" point to a URL that is located inside a different project.

Obligatory

gif

jpg

jpeg

imagertl

URL that points to the image that is shown as icon.

The URL either is an absolute URL or a relative URL. If using a relative URL then be aware of that the generated page is located directly inside your project's directory.

Example: "images/icon.gif" points to an icon in an images-folder that is parallel to the page itself. "../HTMLBasedGUI/images/new.gif" point to a URL that is located inside a different project.

Optional

gif

jpg

jpeg

method

Method of your adapter object that is executed when clicking on the control.

Obligatory  
name

Text that is displayed inside the control. Please do not specify the name when using the multi language management - but specify a "textid" instead.

Optional  
textid

Multi language dependent text that is displayed inside the control. The "textid" is translated into a corresponding string at runtime.

Do not specify a "name" inside the control if specifying a "textid".

Optional  
comment

Comment without any effect on rendering and behaviour. The comment is shown in the layout editor's tree view.

Optional  
Appearance
imagewidth

Pixel width of the image that is shown inside the icon. If not defined then the icon is rendered with its normal width.

Optional  
imageheight

Pixel height of the image that is shown inside the icon. If not defined then the icon is rendered with its normal height.

Optional  
textsize

The HTML font size of the text. Corresponding to the HTML definition "1" means "smallest" and "6" means "biggest".

Optional

imageinactive

If the visibility is dynamically controlled by using the INVISIBLEPROP then there are two ways the icon reacts if the corresponding property passes back "false".

If you want the icon to switch into an inactive status then define inside this property the URL of the image that is the inactive counter part to the normal icon image. Maybe the image is a grayed version of the normal icon image.

If you do not define a value for this property then the icon is made invisible.

Optional

align

Horizontal alignment of control in its column.

Each control is "packaged" into a column. The column itself is part of a row (e.g. ITR or TR). Sometimes the size of the column is bigger than the size of the control itself. In this case the "align" property specifies the position of the control inside the column. In most cases you do not require the align control to be explicitly defined because the size of the column around the controls exactly is sized in the same way as the contained control.

If you want to directly control the alignment of text: in most text based controls there is an explicit property "textalign" in which you align the control's contained text.

Optional

left

center

right

valign

Vertical alignment of control in its column.

Each control is "packaged" into a column. The column itself is part of a row (e.g. ITR or TR). Sometimtes the size of the column is bigger than the size of the control. In this case the "align" property specify the position of the control inside the column.

Optional

top

middle

bottom

withdistance

If set to "true" then 2 pixels of distance are kept on the left and on the right of the icon.

Reason behing: if arranging several icons inside one table row (ITR, TR) then a certain distance is kept between the icons when this property is set to "true".

Optional

true

false

colstyle

CSS style definition that is directly passed into this control.

With the style you can individually influence the rendering of the control. You can specify any style sheet expressions. Examples are:

border: 1px solid #FF0000

background-color: #808080

You can combine expressions by appending and separating them with a semicolon.

Sometimes it is useful to have a look into the generated HTML code in order to know where direct style definitions are applied. Press right mouse-button in your browser and select the "View source" or "View frame's source" function.

Optional

background-color: #FF0000

color: #0000FF

font-weight: bold

spanstyle

CSS style definition that is directly passed into this control.

With the style you can individually influence the rendering of the control. You can specify any style sheet expressions. Examples are:

background-color: #808080

You can combine expressions by appending and separating them with a semicolon.

Optional

background-color: #FF0000

color: #0000FF

invisiblemode

If the visibility of the control is determined dynamically by an adapter property then there are two rendering modes if the visibility is "false":

(1) "invisible": the control is not visible.

(2)"cleared": the control is not visible but it still occupies space.

Optional

invisible

cleared

tabindex

Index that defines the tab order of the control. Controls are selected in increasing index order and in source order to resolve duplicates.
