Glib::RefPtr< Gtk::FontChooser > | wrap (GtkFontChooser* object, bool take_copy=false) |
A Glib::wrap() method for this object. |
An interface implemented by widgets displaying fonts.
FontChooser widgets list the available fonts, styles and sizes, allowing the user to select a font.
To set the font which is initially selected, use set_font_name().
To get the selected font use get_font_name().
To change the text which is shown in the preview area, use set_preview_text().

Glib::ustring Gtk::FontChooser::get_font | ( | ) | const |
Gets the currently-selected font name.
Note that this can be a different string than what you set with set_font(), as the font chooser widget may normalize font names and thus return a string with a different structure. For example, "Helvetica Italic Bold 12" could be normalized to "Helvetica Bold Italic 12".
Use pango_font_description_equal() if you want to compare two font descriptions.
0
if no font is selected. You must free this string with Glib::free(). Pango::FontDescription Gtk::FontChooser::get_font_desc | ( | ) | const |
Gets the currently-selected font.
Note that this can be a different string than what you set with set_font(), as the font chooser widget may normalize font names and thus return a string with a different structure. For example, "Helvetica Italic Bold 12" could be normalized to "Helvetica Bold Italic 12".
