Bug hunt anyone?

Aim is to allow user to switch dynamically between windowed/ fullscreen. So far I'm getting dizzy with going in circles, fix one problem another pops up, fixed that then get another one, fix that and the first pops up again... you get the picture. For starters: ClearScreen() no longer works.

You must call StartDrawing() and StopDrawing() every loop
and not once at start and end.

Try this, F12 for switching screen:

  sh.l  ; Screen Height (fullscreen)

Works here... hopyfully for you too...

Yes, thanks Danilo, this works. By the time I saw your thread I had arrived at the code below. I have noticed a strange difference though: with your solution text is scaled, where as in mine it isn't (only diff appears to be SetFocus_()). I'm finding PB a little unpredictable (not to mention frustrating when things like #PB_Event_MoveWindow have been reported long ago but not fixed).

Info: the aim of the code is to allow a user to switch between windowed and fullscreen. Ultimate aim is PB-only code that works on both Linux and Windows unchanged. Not there yet.

Code: Select all

cBlack  = RGB(0,0,0)
cWhite  = RGB(255,255,255)

cSky    = RGB(192, 192, 255)
