call your UserArea Draw function and call the member function DrawBitmap(...) to draw your image.

See the example kuro posted

no, you have to do it like this:

MyUserArea::Draw(x1,y1,x2,y2)  
{  
     OffScreenOn();  
     SetClippingRegion(x1,y1,x2,y2);  
  
     DrawBitmap(your_bitmap, 0, 0, 81, 81, 0, 0, 81, 81, BMP_NORMAL);  
}

I did, Samir. But I'm drawing it by calling userx->Draw(0,0,81,81); from inside my dialog routines. Or, how should I draw it?

? you don´t need to call it seperately. Once you call the Draw method as I posted it, it will be drawn. If you change the bitmap, all you need to do is redrawing the userarea with userx->Redraw();

Well, the Draw method is never called. I placed a println in there and nothing is printed to the Console
Want me to send you the listing?

Hey, you guys are having way to much fun without me!

Actually getting the GeUserArea to Draw() is the tricky part. As you can see by my code, I just 'force' a draw in the GeUserArea Init() method.

Let me know how it turns out.

The code works as expected. It doesn´t seem to work for Rui on his MAC though. However, I assumed that the picture files he uses may be "unusable" (maybe due to unsupported compression types or similar). Rui wanted to check if other pic types do work for him. He´ll get back to us when he knows more.

Gotcha. Here's hoping that it's unusable image formats and not something more sinister.

Thank you very much Robert and Samir.
It was in fact the file format. I changed it to uncompressed tiff and is working now. I always thought that jpeg was fine but I guess I will go on using uncompressed tiff from now on.
