Possible solution: Use the pixmap engine. It seems to support the "detail"
parameter, so I can specify many additional sections, one for each detail.
Example:
style "track"
{
engine "pixmap"
{
image
{
function = BOX
recolorable = TRUE
detail = "segment"
file = "Extra/track-segment-type1.png"
border = { 5, 5, 5, 5 }
stretch = TRUE
orientation = HORIZONTAL
}
}
}
.. This style will draw the image "Extra/track-segment-type1.png" when
invoked with this command (in PyGTK):
self.styleTrack.paint_box (self.window, gtk.STATE_NORMAL,
gtk.SHADOW_IN, None, None, "segment", X,Y,W,H)
But since the pixmap-engine really did turn out to be rather heavy, I will
have to settle for less:
HOW CAN I DRAW a theme'd box (using gtk_paint_box) in colors different
from what the theme has chosen for my GtkDrawingArea?
Do I have to modify_bg before each call to paint_box, and then reset it
again afterwards?
