Hope someone can help me on this one, on Windows and Linux I need to
stop flicker, so I use an offscreen to buffer like this:
// Offscreen
// The Buffers are properties of this Window
AZBuffer=newpicture(AZCanvas.width,AzCanvas.height,24)// Offscreen
for AZ
AZbuffer.graphics.forecolor=self.backcolor
AZbuffer.graphics.fillrect(0,0,AZCanvas.width,AZcanvas.height)//fill
canvas with window backcolor
AZbuffer.graphics.textfont="Helvetica"
AZbuffer.graphics.textsize=40
AZbuffer.graphics.bold=true
AZbuffer.graphics.italic=true
AZbuffer.graphics.drawstring AZTEXT,10,50
// Blit Offscreens to canvases
AZCanvas.graphics.drawpicture AZbuffer,0,0
My problem is with the color of the fill of the canvas, I want it to
match the window background color.
If I use the following to fill the eventual canvas, and have the
'hasbackcolor=true' for the window then it works fine, however I would
like to not use my own window backcolor, rather let the appearance
theme govern the backcolor of the window.
If I turn off hasbackcolor for the window then my code still uses
whatever color I had chosen for the backcolor rather than the theme's
color.
If I don't do the following code then the canvas ends up with a white
background.
AZbuffer.graphics.forecolor=self.backcolor
AZbuffer.graphics.fillrect(0,0,AZCanvas.width,AZcanvas.height)//fill
canvas with window backcolor
Is there a simple way around this?
Many thanks
