Here is an outline of the hierarchy design that I came up with for my
Main Window: GtkWindow: main application window
GtkVBox: to hold the menu, toolbar, application client area
Client Area: not sure about the type of this object, see below
GtkFixed: to manage the coordinate of few widgets that will be
needed in the client area
MyObjects: see below
For the client area I need something that I can draw on. My first
thought was GtkDrawingArea, however, I run into problems when I tried
to attach the GtkFixed child. GtkDrawingArea is not a container right?
Then I tried GtkWindow and it didn't work either (the name is kind of
misleading, isn't it). At the end I decided that probably the best
match is GtkBin, the reason, the client area is going to have a single
child, namely the GtkFixed.
My objects I created as GtkMisc (after few other tries), because I
want them to be window less, like GtkLabel. I added function members
to handle EXPOSE events.
THE PROBLEM is that I receive the expose event in the Client Area, so
I can draw the background etc, however, I don't get any expose events
in MyObjects. They are on the top of the client area, but they don't
receive any draw messages.
One more thing, I'm using gtkmm, that's why I didn't attach the code.
However, I don't think that's gtkmm issue.
Any idea/explanation about event propagation in Gtk?
