I found some documentation on the use of rc files and think that's the way
to go, but I still cannot get the
font size to change.
I have an RC file that is:
style "Application"
{
font="-*-courier-*-*-*-*-10-*-*-*-*-*-*-*"
}
In my code I am trying to do this for a Dialog base class as a test to get
all dialogs which derive from this to
change the font size.
I have this as a class definition:
class CDialog : public Gtk::Dialog
{
....
};
In my constructor, which I verified is being run, the gobj() is returning a
ptr to the underlying C object, I do this:
CDialog::CDialog(....)
{
GtkDialog * pWidget = gobj();
gtk_parse_rc(myFilename);
gtk_widget_set_name((GtkWidget *)pWidget, "Application");
...
}
I have also moved the above code to be just before the dialog is shown on
the screen (it is loaded invisible).
Same results:
at run time, I get the following assertion failures:
fonts.c pango_font_description_get_size assertion desc != NULL failed
fonts.c pango_font_description_set_size assertion desc != NULL failed
Gtk::RcStyle::set_font assertion font_desc.gobj() != 0 failed.
Any help would be greatly appreciated!

I have an application running on Linux 9, useing Glade to design the UI,
then libglade to load/process
the xml. The backend code is written in C++ using gtkmm.
When i design the UI screens, they are fine. When I load the XML file, then
call get_widget to put the
dialogs and windows and controls onto the screen, they have a totally
different and much larger font size
than was used during the glade session for design.
How can I change the font size used by the application at run time? I have
found sample code to change
font characteristics for a control, but I need to do it for all controls in
all windows.
Any help would be appreciated.
Thanks!
Bob
