ResizeScreen()

[GPI]

A small example, what i want. I render the screen on a Containergadget, so i can "resize" the screen-size while autostretch is activated. I do this, because i want the correct aspect ration, so a circle is stll a circle and not a ellipse for exaple.

(windos directx only)

Code: Select all

#screenw=320
#screenh=200
#win_main=0

#gadget_screen=1

Procedure ResizeContainer()
  menuheight=MenuHeight()
  w= WindowWidth(#win_main)
  h= WindowHeight(#win_main) - MenuHeight
 
  If Int(#ScreenW * h/#ScreenH) <= w
    sw=Int(#ScreenW * h/#ScreenH)
    sh=h
  Else
    sw=w
    sh=Int(#ScreenH * w/#ScreenW)
  EndIf
  sx=Int(w-sw)/2
  sy=Int(h-sh)/2+MenuHeight()
 
  ResizeGadget(#gadget_screen,sx,sy,sw,sh)
EndProcedure

 

If InitSprite() = 0
    MessageRequester("Error", "Can't open screen & sprite enviroment!", 0)
    End
  EndIf
 
 
 
  If OpenWindow(#win_main, 0, 0, 320, 200, "A screen in a window...", #PB_Window_SystemMenu | #PB_Window_SizeGadget | #PB_Window_ScreenCentered)
    ;CreateStatusBar(0, WindowID(0))
    ;  AddStatusBarField(320)
    ContainerGadget(1, 0, 0, 320, 200 ,#PB_Container_BorderLess )

    ;StatusBarText(0, 0, "Automatically zoomed screen area when changing window size...")
   
    If OpenWindowedScreen(GadgetID(1), 0, 0, 320, 200, 1, 0, 00)
 
      CreateSprite(0, 50, 50) ; Erstellt ein leeres Sprites, dies wird komplett schwarz sein
       
      Repeat
        ; Es ist sehr wichtig, alle im Queue befindlichen Ereignisse während jedes Frames abzuarbeiten
        ;
        Repeat
          Event = WindowEvent():Delay(0)
          If event=#PB_Event_SizeWindow
            ResizeContainer()
          ElseIf Event = #PB_Event_CloseWindow
            End
          EndIf
        Until Event = 0
       
        FlipBuffers()
        ClearScreen(RGB(0, 0, 200)) ; Ein blauer Hintergrund
       
        DisplaySprite(0, 10, 10)  ; Darstellung unserer schwarzen Box in der linken oberen Ecke
        DisplaySprite(0, 260, 10) ; Darstellung unserer schwarzen Box in der rechten oberen Ecke
      ForEver
     
    Else
      MessageRequester("Error", "Can't open windowed screen!", 0)
    EndIf
  EndIf

it would be easier with a

resizeWindowedScreen(top,left,bottom,right)

Good request, I'd like it too.

Just bear in mind that if you place a WindowedScreen in a container you will lose the capacity to use InitMouse() and all the mouse commands it provides. Keyboard should still be OK and API mouse control is always available.
