Connecting the realize signal does not work any better than map and
map-event. :o(
According to this page, the realize signal is emitted even before map :

Other ideas?

Hullo,
I'm trying to change the font (face and style) in a custom object
derived from Entry.
I use the following code:
Pango::FontDescription
fd(get_layout()->get_context()->get_font_description());
if (word.HasSerif())
fd.set_family("times");
else
fd.set_family("arial");
if (word.IsItalics())
fd.set_style(Pango::STYLE_ITALIC);
else
fd.set_style(Pango::STYLE_NORMAL);
get_layout()->get_context()->set_font_description(fd);
This seems to need the widget to be associated to a fully functionnal
GdkWidow, so rather than putting this code in the constructor, I
connected it to a signal.
I tried map and map-event but it did not work. I thought that these
signals where emitted when (resp.) asking to associate and associating
the widget to a GdkWindow…
I also tried expose-event, which is supposed to be emitted when the
widget is rendered, and it changes the font only when the edit gets the
focus! O_O
Do you have any insight on the matter, please?
You can use the Gtk::Widget::signal_realize(). When it is emitted, the
Gdk::Window associated with the widget should be fully functional.
