We can detect the window closing with PB constant #PB_Event_CloseWindow.

If I want to detect the window is minimizing by the user, what will be the PB constant? #PB_Event_MinimizeWindow?

Check the wParam of #WM_SIZE wich can be:

SIZE_MAXHIDE
Message is sent to all pop-up windows when some other window is maximized.
SIZE_MAXIMIZED
The window has been maximized.
SIZE_MAXSHOW
Message is sent to all pop-up windows when some other window has been restored to its former size.
SIZE_MINIMIZED
The window has been minimized.
SIZE_RESTORED
The window has been resized, but neither the SIZE_MINIMIZED nor SIZE_MAXIMIZED value applies.

minimizing seems to be a #PB_Event_MoveWindow.

check it out:

Code: Select all

If OpenWindow(0, 0, 0, 500, 400, "", #PB_Window_SystemMenu | #PB_Window_ScreenCentered | #PB_Window_MaximizeGadget | #PB_Window_MinimizeGadget ) 
   Repeat 
      Event = WaitWindowEvent() 
      Debug event 
   Until  Event = #PB_Event_CloseWindow 
EndIf

to determine if it is a move or a minimize you may have to check the messages like Fluid said...

Code: Select all

#APPNAME = ""
#WndMain = 0

OpenWindow(#WndMain, 0, 0, 640, 480, #APPNAME, #PB_Window_MaximizeGadget | #PB_Window_MinimizeGadget | #PB_Window_SizeGadget | #PB_Window_ScreenCentered | #PB_Window_SystemMenu)
CreateGadgetList(WindowID(#WndMain))

Repeat
  Select WaitWindowEvent()
    Case #PB_Event_DeactivateWindow
      If GetWindowState(#WndMain) = #PB_Window_Minimize
        Debug "Minimized"
      EndIf
    Case #PB_Event_CloseWindow
      Break
  EndSelect

#PB_Event_MoveWindow works, too:

Code: Select all

OpenWindow(0, 0, 0, 500, 400, "", #PB_Window_SystemMenu | #PB_Window_ScreenCentered | #PB_Window_MaximizeGadget | #PB_Window_MinimizeGadget ) 
OldState = GetWindowState(0)

Repeat 
  Event = WaitWindowEvent() 
  Select Event 
    Case #PB_Event_MoveWindow
      State = GetWindowState(0)
      If State <> OldState
        OldState = State
        Select State
          Case #PB_Window_Minimize
            Debug "just minimized"
          Case #PB_Window_Maximize
            Debug "just maximized"
          Case #PB_Window_Normal
            Debug "original size"
        EndSelect
      EndIf
  EndSelect
Until  Event = #PB_Event_CloseWindow

#PB_Event_MoveWindow works, too:
not on linux

saw your topic... did you test it with my code, too?

Posted: **Thu Mar 08, 2007 2:42 pm**

the code by trond works only on linux (the constant is'nt available in windows) ,
and the code by kaeru works only in windows

No, it should be crossplatform compatible. Everything used is available on both systems.

But the question is if this is required at all.

>> it should
but is it

Posted: **Thu Mar 08, 2007 3:16 pm**

Running in my PB4.02/Win2000,
#PB_Event_DeactivateWindow is not found

[ ADDED ]
Yes, Kaeru Gaman's code is working

Thanks

Finally, I find a very brief/straight-forward answer

Code: Select all

 if IsIconic_(WindowID(MainWindow))
. . . .
endif

well.. since this is WinAPI it's windows pure and no PB-solution.
