Release 10.1A: OpenEdge Development:
AppBuilder

Run-time properties and AppBuilder settings

For each alternate layout, the AppBuilder places an IF statement in the Run-time Properties and AppBuilder Settings code section. This IF statement checks to see whether the layout’s run-time expression evaluates to TRUE. If so, this statement runs the layout case’s internal procedure, passing to it the name of the layout as an input parameter.

For example, the multi-layout run-time adjustments code appears as follows:

/* _MULTI-LAYOUT-RUN-TIME-ADJUSTMENTS */ /* LAYOUT-NAME: "Standard Character" LAYOUT-TYPE: CHARACTER EXPRESSION: SESSION:DISPLAY-TYPE = ’TTY’:U COMMENT: This layout is the standard layout specification for a customized Character based terminal. It is usually selected to modify a window that has a GUI based master layout. */ IF SESSION:DISPLAY-TYPE = ’TTY’:U THEN RUN C-Win-layouts (INPUT ’Standard Character’:U) NO-ERROR. /* LAYOUT-NAME: "Standard MS Windows" LAYOUT-TYPE: GUI EXPRESSION: SESSION:WINDOW-SYSTEM = ’MS-WINDOWS’:U COMMENT: This layout is the standard layout specification for a customized MS Windows window. It is usually selected to modify a window that needs to have a standard "MS Windows" look. */ ELSE IF SESSION:WINDOW-SYSTEM = ’MS-WINDOWS’:U THEN RUN C-Win-layouts (INPUT ’Standard MS Windows’:U) NO-ERROR. /* LAYOUT-NAME: "Standard Windows 95" LAYOUT-TYPE: GUI EXPRESSION: SESSION:WINDOW-SYSTEM = ’MS-WIN95’:U COMMENT: This layout is the standard layout specification for a customized Windows 95 window. It is usually selected to modify a window that needs to have a standard "Windows 95" look. */ ELSE IF SESSION:WINDOW-SYSTEM = ’MS-WIN95’:U THEN RUN C-Win-layouts (INPUT ’Standard Windows 95’:U) NO-ERROR. /* END-OF-LAYOUT-DEFINITIONS */ IF SESSION:DISPLAY-TYPE = "GUI":U AND VALID-HANDLE(C-Win) THEN C-Win:HIDDEN = no.

If the expression SESSION:WINDOW-SYSTEM = ’MS-WINDOWS’:U evaluates to TRUE, this IF statement passes the input parameter ’Standard MS Windows’ to the layout cases internal procedure. For SmartObjects, the DefaultLayout property is set. This is used to run the appropriate layout case later, when the SmartObject is initialized.

Thus, for SmartObjects, the multi-layout run-time adjustments code appears as follows:

/* _MULTI-LAYOUT-RUN-TIME-ADJUSTMENTS */ /* LAYOUT-NAME: "Standard Character" LAYOUT-TYPE: CHARACTER EXPRESSION: SESSION:DISPLAY-TYPE = ’TTY’:U COMMENT: This layout is the standard layout specification for a customized Character based terminal. It is usually selected to modify a window that has a GUI based master layout. */ IF SESSION:DISPLAY-TYPE = ’TTY’:U THEN DYNAMIC-FUNCTION(’setDefaultLayout’:U, ’Standard Character’:U) NO-ERROR. /* LAYOUT-NAME: "Standard MS Windows" LAYOUT-TYPE: GUI EXPRESSION: SESSION:WINDOW-SYSTEM = ’MS-WINDOWS’:U COMMENT: This layout is the standard layout specification for a customized MS Windows window. It is usually selected to modify a window that needs to have a standard "MS Windows" look. */ ELSE IF SESSION:WINDOW-SYSTEM = ’MS-WINDOWS’:U THEN DYNAMIC-FUNCTION(’setDefaultLayout’:U, ’Standard MS Windows’:U) NO-ERROR. /* LAYOUT-NAME: "Standard Windows 95" LAYOUT-TYPE: GUI EXPRESSION: SESSION:WINDOW-SYSTEM = ’MS-WIN95’:U COMMENT: This layout is the standard layout specification for a customized Windows 95 window. It is usually selected to modify a window that needs to have a standard "Windows 95" look. */ ELSE IF SESSION:WINDOW-SYSTEM = ’MS-WIN95’:U THEN DYNAMIC-FUNCTION(’setDefaultLayout’:U, ’Standard Windows 95’:U) NO-ERROR. DYNAMIC-FUNCTION(’setLayoutOptions’:U, "Master Layout,Standard Character,Standard MS Windows,Standard Windows 95":U).
