Ive been working like mad for a couple of hours now. I havent made the base WiW
widget yet, but that shouldnt take all that long, as the WiW child is the really
important part. At the moment, things are looking pretty spiffy, but I have run
into a small problem with the drawing of the widget. Since it is based on a
GtkVBox, which is transparent, i have to write the code to put the background
color and such behind the WiW Child widget, as well as add a border etc. I have
this done fairly well with a single sub window, but when sub windows overlap,
the sub window on the top doesnt draw over the other widgets that are inside the
sub window that it is overlapping. Ive looked at some code for the gtkbutton and
other, and havent been able to discern a reason for this.
Here is the code:
static void paint_wiw(GtkWidget *widget, GdkRectangle *area)
gtk_paint_box(widget->style, widget-window, GTK_STATE_NORMAL,
area, widget, "button",
which is mostly jacked from the gtkbutton widget.
This, along with code to redisplay all the children of the subwindow, is called
for hide, draw, and expose events.
If anyone see's something that I have forgoten, please let me know.
And keep reading for more info...

Right now im just using buttons with text (yeah, just about a cheesy as they
come), but when i get the interface worked out, i will make some generic
pixmaps. I would love it if this widget eventually got into the gtk+ 1.4 release
or something, then its settings could be added to the gtkrc, and its look could

I think that im going to leave this up to the layout widget GList. When i focus
a sub window, ill just change the order of the GList (namely, move the selected
one to the top).

No, it wasnt what i was taking about, but its a hell of a lot easier, so thanks
a bunch, it works now.
