The following topics are covered below:
To edit a dialog's source code
Load the dialog into the editor.
From the menu, choose .
Or:
Press CTRL+ALT+C.
The dialog's source code window appears and the program editor is loaded. This editor enables you to scan for text strings, replace them, and so on.
You can switch between the dialog editor and the program editor by selecting the source code window or the dialog window. If you edit in either window, you need to synchronize your updates: (graphically) modifying the dialog locks the source code window and you may not make changes there. Correspondingly, if you change the source code, you may not make changes in the dialog window, which is locked. If your editor is locked, its status bar displays "Locked".
If a source code window is open, but not active, you can activate it by choosing from the menu.
When you issue a command from the program editor window that affects the source code, such as or , the dialog editor updates itself automatically by scanning the source code, displaying the modified dialog, and then regenerating the source code. When you issue a command from the dialog editor window after you have modified the code in the source code window, you are prompted whether you want to update the source code or not.
To stow any modified source code: from the program editor's menu, choose .
Whenever you want to save a dialog under a new name, select from the menu, where for the Save dialog as dialog box appears.
To edit a dialog's attributes
Load the dialog into the editor.
From the menu or from the dialog's context menu, choose .
Or:
Double-click on the dialog.
Or:
Press ENTER.
The dialog's attributes window appears. To find out what the entries in the attributes window mean, choose "Help". For context-sensitive help, select the attribute entry and press F1.
Enter the desired attribute values.
Choose to confirm your changes.
To edit a dialog's event handlers
Load the dialog into the editor.
From the menu or from the dialog's context menu, choose .
Or:
Press CTRL+ALT+E or SHIFT+ENTER.
The dialog's event handler section appears.
Select the type of event (such as BEFORE-OPEN or ERROR).
Or:
Choose "New" to enter a user-defined event.
Or:
Choose "Rename" to save a user-defined event with a new name.
Enter the desired event code in free form either in the edit window in the Dialog Event Handler window itself, or using the Program Editor. To use the Program Editor, select the push button, then close the Dialog Event Handler window using the push button. This code will be executed when the event occurs for the dialog. Note that if you have specified code in the before-any and after-any event sections, this will be triggered before and after the code entered here. So if you need common event code, you only have to enter it once in your dialog's before-any and after-any event section.
Choose to save your code, if using the Dialog Event Handler window. If using the Program Editor, the code can be saved by choosing from the menu, or by closing the Program Editor and selecting to save the changes when prompted.
To define a dialog's menu bar
Load the dialog into the editor.
From the menu, choose .
Or:

You use timers to trigger a dialog event periodically.
To create and maintain a timer for a dialog
Load the dialog into the editor.
From the menu, choose .
Or:
Press CTRL+ALT+I.
The timer's attributes window appears. For more information on the attributes window, see the section Timer Attributes Window.

item will then inherit the attributes from the signal. Furthermore, when the
menu or toolbar item is clicked on running the dialog, the signal's
CLICK
event is invoked.
You use context menus to define context-specific menus that can be associated with the dialog and/or any number of dialog elements within it. For more information, see the section Defining and Using Context Menus.

To associate the context menu with the dialog or a dialog element within the dialog, open the corresponding attributes window (e.g. by double-clicking on the dialog or dialog element) and select the context menu from the list presented in the Context Menu field. Note, however, that not all dialog element types support context menus.
You use wallpapers to define background images that can be associated with the dialog and/or any number of dialog elements within it.
To create and maintain wallpapers
Load the dialog into the editor.
From the menu, choose .
Or:
Press CTRL+ALT+W.
The wallpaper attributes window appears. For more information on the attributes window, see the section Wallpaper Attributes Window.

Natural contains an integrated Help Organizer, which allows the definition of simple (e.g., pop-up) help text for a dialog. In order to create more elaborate and/or HTML-based help content, a third-party help authoring tool will be required. For more information on the Help Organizer, see Organizing an Application's Help File.
To define help text for a dialog
Load the dialog into the editor.
From the menu or from the dialog's context menu, choose .
Or:
Press CTRL+ALT+H.
The help organizer's main window appears. For more information, see Using the Help Organizer's Main Dialog.
Choose or to confirm your changes.
To generate the help, load the generated help project (.hpj) file
into the Microsoft Help Compiler Workbench (HCW.EXE) and compile the help
project. The resulting help (.hlp) file can be deployed in the RES subdirectory
of the logon library, the RES directory of one of the steplibs, or the
directory assigned to the environment variable
NATGUI_BMP.
To associate the compiled help file with the dialog, select the file in the Help file field in the dialog attributes window. Select the Help button option in the dialog attributes window if you wish a help (question mark) button to appear in the window's title bar (cannot be used in conjunction with the minimize or maximize buttons). Select the Popup help option in the dialog attributes window if you wish the help to be displayed in a small tooltip-style window instead of a full-blown help window.
To invoke the help when the dialog is running, either press F1 to display the help corresponding to the dialog element with the focus, or select the help button (if available) then select the desired dialog element (or the dialog itself). Note that if the dialog element has a help ID of zero, the help ID of its parent is used to identify the help topic to be displayed.
The control sequence is the keyboard navigation sequence in which the end user will go through the dialog elements.
To define the control sequence of a dialog
From the menu, choose .
Or:
Press CTRL+ALT+Q.
The control sequence is displayed as a number at the top left corner of each dialog element. The editor is now in navigation sequence definition mode.
Use the mouse to select the dialog elements in the desired sequence.
If you do not select a dialog element before enabling navigation sequence definition mode, the next dialog element that you select will be the first in the navigation sequence. Its number is greyed and you can select the next dialog element in the sequence, and so on.
If you do select a dialog element, you can redefine the sequence from this element onwards. You can also select a dialog element when in control sequence editing mode without resequencing it by holding down the SHIFT key whilst making the selection. This is especially useful if the selected dialog element is one of the last elements in the sequence - you do not have to redefine the sequence of all preceding dialog elements. Note that instead of selecting each dialog element with the mouse, you can also select them from the selection box in the status bar of the dialog editor. This selection box always shows the dialog elements in their control sequence.
You can exit control sequence editing mode implicitly, by selecting another command (e.g. 'Insert Push Button') or explicitly by selecting the 'control sequence' menu of this again, or by pressing ESC.
Note:
The control sequence also decides the order in which the dialog
elements overlap.
