Syntax

Procedure OnBeginningOfPanel Integer hoPanel

Description

OnBeginningOfPanel is sent to the tab-dialog when Beginning_of_panel is sent by a parent (normally the view). This notification can be used to switch to any desired tab page as part of a beginning_of_panel event. These events are most often triggered by a clear or a save.

By default this method brings the tab page number stored in the default_tab property back to the top. The code in the package looks like this:

Procedure OnBeginningOfPanel integer hoPanel
   // note if default tab is -1, this behavior is stopped
   if (Button_Count(self) and Default_Tab(self)>=0) ;
            send Request_Tab_display
end_procedure

By default, default_tab is 0 so this will cause the first tab page to be displayed.

This method can be augmented to change the behavior as you wish. Note that setting the default_tab property of the tab-dialog to -1 will disable this behavior.

To see this behavior try running the customer view with tab dialogs. When you press clear, the first tab page is restored.
