Umm, an ever weirder problem now. I
tried the suggestions posted earlier, I Inside my setFont( ... )
function where I receive the according properties:
Gtk::Widget* w = 0;
w = this->button->get_child();
assert( w );
The assert fails with the error:
factory:
/home/teratux/Workspace/apps/factory/src/gtk/gtk_button.cpp:39:
virtual void GTKButton::setFont(FontType, FontSize, FontSeries,
FontShape): Assertion `w' failed.
Meaning the button has no child widgets. I'm using gtkmm2, if I
didn't mention it earlier.

On how many widgets does this happen

If that's the case, I'll somehow have to typecast to resolve the
button's issue

You can change the style of most widgets. My
point is - and that's also what Murray's links describe - that
it has no effect to change the font of a Gtk::Button, because
the Button does not write the text in it. The text is written
by a Label, which is the child of the Button. You must change
the Label's font.

Actually this->object is a Gtk::Widget. I'm implementing a class
hierarchy using the abstract factory pattern, which means that all
widgets should be treated equal in this point where I request to
change the widget's text style. Can I only change widgets that
inherit from Gtk::Bin ??
Plenty of people get confused by this. I don't like this part of the GTK
+ API either. For instance:
https://bugzilla.gnome.org/show_bug.cgi?id=566945
In Glom, I have hidden the ugly dynamic casting, and some other
weirdness, in a utility method:
