Creating and Accessing a Handler from the Form Designer (Magic xpa 4.x)

You can create a new event handler for a specific control, view its already defined handler, and switch to these handlers directly from the visual representation of the control on the Form Designer.

In the context menu opened from a control, you can see the names of the already defined handlers. Selecting one of these menu options automatically switches to the handler’s logic unit definition in the logic layer.

• Existing handlers for the control – Shows all of the event handlers (defined in the current task) that exist for that control.
  
  For Push Button controls with an event defined in the Event property, if there is a general handler (not control-specific) for this event, it will also be shown in this group.

• Create New Handler – Creates a handler for that control. If performed when not parking on a control, a new header line will be created as the last entry in the Logic tab.
