Hi, I want to get_approximate_char_width() so as to limit the width of a widget (TreeView) according to a given number of characters. The problem is I access the current font for a given widget in this way:
widget->get_style()->get_font() that returns a Pango::FontDescription object but the function "get_approximate_char_width()" applies on a Pango::FontMetrics object --> How can I get the FontMetrics from the FontDescription?? I have spent some time with the gtkmm documentation but i can't find how I can get a FontMetrics class from a Pango::FontDescription. or maybe should i access the current font used for the widget in another way (that returns something else than a FontDescription)?? thanks for your help
