Hi, For a specialized (audio pattern) editor I'm currently drawing everything on a off screen pixmap, and calling gdk_draw_drawable() to copy the needed areas on expose events into a drawing area's GdkWindow.
I would like to draw some widget parts (a ruler actually) using the gtk_paint_*() methods into this editor. However, since the whole drawing process is made off screen using some sort of layers, I can't draw directly on the GdkWindow. I would prefer to draw the widget parts on the off-screen pixmap. However, all the gtk_paint_*() functions need a GdkWindow to draw on. Funny thing, I've tried to pass my GdkPixmap to gtk_paint_box(), it issued an "invalid cast from `GdkPixmap' to `GdkWindow'", but it did draw ;) Anyway, I sense this isn't the right thing to do. I also thought about having an "off-screen" (never shown) GdkWindow instead of my GdkPixmap. This should work, since all the gdk drawing functions I use expect a GdkDrawable. Is it the right way to do this? Isn't drawing on a GdkWindow heavier, because it implies interactions with X11 (or Quartz, whatever)?
