Hello,

This code snippet is from the PB help.

Is there a way to initially display only the gray interface with buttons, gadgets, and settings options, and then open the OpenWindowedScreen only when a specific button is clicked? Similarly, is there a way to close the screen using KeyboardPushed() and return to the gray interface?

Can OpenWindowedScreen() also be placed above gadgets? Or would you have to hide them first?

Thanks!

Code: Select all

If InitSprite() = 0 Or InitKeyboard() = 0 Or InitMouse() = 0
  MessageRequester("Error", "Can't open the sprite system", 0)
  End
EndIf

If OpenWindow(0, 0, 0, 340, 285, "Gadget and sprites!", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
  ButtonGadget(1, 10,  10, 100, 25, "Grab input")
  TextGadget  (4, 10, 40, 300, 30, "Mouse and keyboard released")

  If OpenWindowedScreen(WindowID(0), DesktopScaledX(10), DesktopScaledX(70), DesktopScaledX(320), DesktopScaledX(200), 0, 0, 0)
    LoadSprite(0, #PB_Compiler_Home + "examples/sources/Data/PureBasicLogo.bmp")

    MouseX = (ScreenWidth() - SpriteWidth(0)) / 2
    MouseY = (ScreenHeight() - SpriteHeight(0)) / 2
    MouseLocate(MouseX, MouseY)
    
    ; Start with released input
    ReleaseMouse(#True)
    InputReleased = 1
    
    Repeat

            EndSelect
        
        EndSelect

          MouseX = MouseX()
          MouseY = MouseY()
        EndIf

          InputReleased = 1

You can use the ScreenGadget Library there v6.30. This is still missing in the index of the PB help.
