BindMenuEvent()
Syntax
BindMenuEvent(#Menu, MenuItem, @Callback())Description
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 EndProcedureRegular 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
