Temporarily Disable Mac Menu Item Quit

[KieferThomas]

Hello All!,

I have an an application I have been updating to make it more readable and manageable for making changes in it.

After working with my original program for several years there is one thing I never took into account. This was the fact of temporarily disabling the Quit Application menu item when another window other then the main window_0 is open.

I know how to access the Quit Application feature in the Mac menu with the -4 Menu Item but what I really need to know is how to temporarily disable it when any other window is open.

I have searched through the forums only getting examples for menu items which are implicitly created by me; there is nothing on the Mac Menu Items and how to disable them.

Any help would be appreciated,

Thanks in advance,
Kiefer

I had forgot to mention: DisableMenuItem(0, -4, 1) does not disable the Quit Item.

Hi, some comments:

1. On Mac there is a constant named #PB_Menu_Quit so you don't need to use a magic number like -4.

2. I don't think you CAN disable that menu item... I think it's a special one generated by the OS.

3. Instead of disabling the menu event itself... can't you just disable your program's response to the event?

Code: Select all

Case #PB_Menu_Quit
  If (InMainWindow)
    Quit()
  Else
    ; Do not quit!
  EndIf

4. I'm not a Mac expert... In a standard Mac program, when you press Cmd-Q to quit a program, is it only expected to work in the main window, or in sub-windows too? I'm not sure.


EDIT: OK, I thought you were talking about the Cmd-Q hotkey but now I think you really mean the "Quit" entry in the menu list... Maybe that can be disabled? But my comments mostly still apply

Hey kenmo,
Thank you! This managed to get me in the right direction.

I made my modifications as follows:

Code: Select all

Case #PB_Event_Menu
      Select EventMenu()
              
           Case #MenuItem_2
               HideWindow(#Window_0,1) 
               HideWindow(#Window_1, 0)
          Case #PB_Menu_Quit CocoaMessage(0, WindowID(#Window_0), "isVisible")
               If  Not IsVisible
                    MessageRequester("You can not close the application with this window open!","")
               Else 
                    appQuit = 1
               EndIf

This keeps the program from Ending until I get back to Window_0.


By the way you are correct about the Mac Menu they are special. I have only been able to find a limited amount of support for them.

Thanks Again,
Kiefer
