Here's a code snippet I'm using (mostly taken from df_window.c):
DFBWindowDescription desc; desc.flags = ( DWDESC_POSX | DWDESC_POSY | DWDESC_WIDTH | DWDESC_HEIGHT | DWDESC_CAPS ); desc.posx = 200; desc.posy = 200; desc.width = 400; desc.height = 300; desc.caps = DWCAPS_ALPHACHANNEL;
DFBCHECK(layer->CreateWindow( layer, &desc, &window ) ); window->GetSurface( window, &window_surface );
window_surface->SetColor( window_surface, 0xFF, 0x20, 0x20, 0x90 ); window_surface->DrawRectangle( window_surface, 0, 0, desc.width, desc.height );
window_surface->SetDrawingFlags( window_surface, DSDRAW_NOFX );
window_surface->SetColor( window_surface, 0x00, 0x00, 0x00, 0xff ); window_surface->DrawString( window_surface, "Earth", -1, 10,10, DSTF_LEFT | DSTF_TOP );
window_surface->Flip( window_surface, NULL, 0 );
Am I on the right track? Or is this completely wrong?
I thought by setting DSDRAW_NOFX to the surface would make the text opaque, but it doesn't. This is the first graphics related programming I've done so there's a good chance I'm doing something fundamentally incorrect.

I have a IDirectFBSurface that I'm drawing some text on. The surface is in a IDirectFBWindow. If I set the window's opacity I can make the window translucent. This works perfectly.
Is it possible to have the text on the surface stay
opaque but the rest of the surface translucent? Perhaps I should create 2 windows? One with the text
and one with the translucent color?
You will need to use a window with alphachannel, fill it with translucent background and draw opaque text on it.
