The code looks fine (and works here) so I guess the 'fullScreenView' is
not being set correctly or is being set to w32False somewhere else.



Here is the code I used to test it...

without warning
include win32lib.ew
integer fullScreenView fullScreenView = w32False

constant mw = create(Window, "Main", 0, 0, 0, 100, 100, 0)
constant win_FullScreen = create(Window, "FULL", 0, 200, 200, 400, 400, 0)


procedure win_FullScreen_onKeyPress (integer self, integer event, sequence
params)--params is ( int keyCode, int shift )
    if params[1] = VK_ESCAPE then
       if  fullScreenView = w32True then
            closeWindow( win_FullScreen )
       else
            openWindow(win_FullScreen, Normal)
       end if
    end if
end procedure
setHandler( Screen, w32HKeyPress, routine_id("win_FullScreen_onKeyPress"))

procedure win_FullScreen_onActivate (integer self, integer event, sequence
params)
    fullScreenView = w32True
end procedure
setHandler( win_FullScreen, w32HActivate,
routine_id("win_FullScreen_onActivate"))
    
procedure win_FullScreen_onClose(integer self, integer event, sequence params)
    fullScreenView = w32False
end procedure
setHandler( win_FullScreen, w32HClose, routine_id("win_FullScreen_onClose"))

openWindow(win_FullScreen, Normal)

WinMain(mw, Normal)

I verified that fullScreenView is being set properly. I even used this:

but it still doesn't work!

Your code works, of course... :/ :)

Maybe I should get the latest patch to Win32Lib? :)

It doesn't, for this exercise. See example code below.

Are you sure the menu click is actually firing?

without warning
include win32lib.ew
integer fullScreenView fullScreenView = w32False

constant mw = create(Window, "Main", 0, 0, 0, 100, 100, 0)
constant win_FullScreen = create(Window, "FULL", 0, 200, 200, 400, 400, 0)

procedure win_FullScreen_onKeyPress (integer self, integer event, sequence
params)
    if params[1] = VK_ESCAPE then
        fullScreenView = (not fullScreenView)
        showWindow( win_FullScreen, fullScreenView )
    end if
end procedure
setHandler( Screen, w32HKeyPress, routine_id("win_FullScreen_onKeyPress"))

WinMain(mw, Normal)
