SetWindowState unhides - Bug or Feature?

I'm not sure. Should it be possible to maximize an hidden window?

I'd like to create a window with lot of gadgets and restore it with
the styles and dimensions from a saved session.
And only wants to show if everything is ready..

Code: Select all

OpenWindow(0, 0, 0, 800, 600, "SetWindowStateBug", #PB_Window_SystemMenu|#PB_Window_Invisible)
MessageRequester( "", "Windows is unvisible", 0 )
; Window should stay unvisible..
SetWindowState( 0, #PB_Window_Maximize )
MessageRequester( "", "Windows is still unvisible??", 0 )
HideWindow(0, #False)
MessageRequester( "", "Windows is now visible", 0 )
Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow

HideWindow(#Window_Icat, 0) ; Unhide the window now

Didn't unhide it!!

SetWindowState(#Window_Icat, #PB_Window_Normal)

Now it did.

Found this for a couple of pb versions to 4.10. Haven't tried it with 4.2 yet. Even with the maximize flag, same problem.

dige:
Its a Windows feature i guess. SetWindowState simply calls ShowWindow(x, SW_MAXIMIZE),
and it seems this cannot be combined with SW_HIDE:

Code: Select all

OpenWindow(0, 0, 0, 800, 600, "SetWindowStateBug", #PB_Window_SystemMenu|#PB_Window_Invisible)
MessageRequester( "", "Windows is unvisible", 0 )
; Window should stay unvisible..
;SetWindowState( 0, #PB_Window_Maximize )
ShowWindow_(WindowID(0), #SW_MAXIMIZE|#SW_HIDE)
MessageRequester( "", "Windows is still unvisible??", 0 )
HideWindow(0, #False)
MessageRequester( "", "Windows is now visible", 0 )
Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow

Fangbeast: show some code please.

Maybe you just have the window in the minimized state and then showing it will of course not make
it appear on screen.

As a solution, it seems to work if you create the window invisible and maximised, so you would have to get the sizes from your session and apply them at the point you create the Window.

Code: Select all

OpenWindow(0, 0, 0, 0, 0, "SetWindowStateBug", #PB_Window_SystemMenu|#PB_Window_Invisible|#PB_Window_Maximize)
MessageRequester( "", "Windows is unvisible", 0 )
; Window should stay unvisible..
;SetWindowState( 0, #PB_Window_Maximize )
;MessageRequester( "", "Windows is still unvisible??", 0 )
HideWindow(0, #False)
MessageRequester( "", "Windows is now visible", 0 )
Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
