BindMenuEvent()

Syntax

BindMenuEvent(#Menu, MenuItem, @Callback())

Bind a menu event to a callback. It's an additional way to handle events in PureBasic, which works without problem with the regulars WindowEvent() / WaitWindowEvent() commands. A menu event can be unbinded with UnbindMenuEvent().

Parameters

#Menu	The menu to bind the event to.
MenuItem	The menu item within the menu to bind the event to.
@Callback()	The callback procedure to call when the event occurs. It has to be declared like this: Procedure EventHandler() ; Code EndProcedure Regular functions like EventGadget(), EventWindow(), EventMenu(), EventType() and EventData() are available within the callback to get more information about the event. Note: WindowEvent() and WaitWindowEvent() should never be called from inside the callback or the program can be locked or have wrong behavior.

Return value

None.

Example

  Procedure TestHandler()
    Debug "Test menu event"
  EndProcedure
  
  Procedure QuitHandler()
    Debug "Quit menu event"
    End
  EndProcedure
  
  OpenWindow(0, 100, 100, 200, 50, "Click test", #PB_Window_SystemMenu)
  
  CreateMenu(0, WindowID(0))
    MenuTitle("File")
      MenuItem(0, "Test")
      MenuItem(1, "Quit")
  
  BindMenuEvent(0, 0, @TestHandler())
  BindMenuEvent(0, 1, @QuitHandler())
  
  Repeat
    Event = WaitWindowEvent()
  Until Event = #PB_Event_CloseWindow
