Hadn't been, but I just tried it. The result was that the entire da is
drawn, but still in the wrong place. It's still aligned with the top of
the vbox, overlays label 1 and label 2, and there's still a big gap
between the bottom of the da and the top of label 3.
It looks to me like the cr being passed to the draw callback is
pointing not to a new drawing area but to some underlying drawing area,
but that's a guess--I don't know a thing about the innards of cairo.
Code patch was:
/***
Fill the entire da with a black a rectangle, then overlay the
black rectangle
with a smaller red one.
Notice that that top edge of the da, the top bit of the black
rectangle,
is cut off.
***/
cairo_reset_clip (cr); // <<<<<<<<<<<<<<<<<<<<<<<<<<
GdkRGBA black = {0.0, 0.0, 0.0, 1.0};
gdk_cairo_set_source_rgba (cr, &black);
cairo_rectangle (cr, 0.0, 0.0, DA_WIDTH, DA_HEIGHT);
cairo_fill (cr);

I just did a good-size upgrade I'd been putting off for too long that took

Basically, I have a window that contains
a vbox that contans
a label another label a drawing area a third label
The problem is that the top of drawing area is lined up with the top of
the enclosing vbox, or maybe at the top of the window, rather than at the
bottom of the second label.
Is there something new I'm missing? It didn't used to work that way.
Do you, by chance, reset cairo clipping when drawing over the drawing area?
