Hello,

The following code does 2 strange things :

#Window_0 = 0
#MenuBar_25 = 0
#MENU_1  = 101
#MENU_2  = 102

#Gadget_1 = 10

Procedure Open_Window_0()
  If OpenWindow(#Window_0, 211, 114, 515, 491, #PB_Window_SystemMenu | #PB_Window_SizeGadget | #PB_Window_TitleBar , "New window ( 0 )")
    If CreateMenu(#MenuBar_25, WindowID())
      MenuTitle("File")
      MenuItem(#MENU_1, "Save")
      MenuItem(#MENU_2, "Quit")
      MenuTitle("About")
    EndIf
    
    If CreateGadgetList(WindowID())
      ButtonGadget(#Gadget_1, 105, 30, 45, 30, "B1")
    EndIf
  EndIf
EndProcedure

Open_Window_0()

Repeat
  Event = WindowEvent()

Menu = EventMenuID() 
  Delay(1)
  
  StartDrawing(WindowOutput())
  Locate( 50, 120 )
  DrawText("MENU "+ Str( Menu  ) + "     ")
  StopDrawing()
  
Until Event = #PB_EventCloseWindow
End

First thing :
If I click on File and select 'Save' value 101 is displayed until I select
another item. EventMenuID() still detect 'Save' selected when the menu
is closed.

Second :
EventMenuID() detects when I click on the button #gadget1. I thought
it was supposed to only detect events on menu... as EventGadget() is
supposed to do with gadgets ONLY.

Any idea

You should check the result from WindowEvent() to determine if it's a gadget event or a menu event or for that matter any other event that is supported..

An event loop typically looks something like this:

Code: Select all

Repeat
  event = WindowEvent()
  if event = 0
    delay(1)
  else
    if event = #PB_Event_Gadget
      select EventGadgetID()
        case #GAD1
           ...
      endselect
    elseif event = #PB_Event_Menu
      select EventMenuID()
        case #Menu1
           ...
      endselect
    endif
  endif
until event = #PB_Event_CloseWindow

Note: I typed this from memory so the constants might be misspelled....

If you use WaitWindowEvent() you don't have to use a delay.
