| 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().
| typedef sigc::slot<bool, const Glib::RefPtr<const Pango::FontFamily>&, const Glib::RefPtr<const Pango::FontFace>&> Gtk::FontChooser::SlotFontFilter |
Font filter callback.
For instance,
| font_family | A Pango FontFamily. |
| font_face | A Font Face belonging to the font_family. |
This is used for deciding what fonts should be shown in a FontChooser. See set_filter_func().

| 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".
Use pango_font_description_equal() if you want to compare two font descriptions.
0 if no font is selected. | Glib::RefPtr<Pango::FontFace> Gtk::FontChooser::get_font_face | ( | ) |
Gets the Pango::FontFace representing the selected font group details (i.e. family, slant, weight, width, etc).
If the selected font is not installed, returns 0.
0. The returned object is owned by fontchooser and must not be modified or freed. | Glib::RefPtr<const Pango::FontFace> Gtk::FontChooser::get_font_face | ( | ) | const |
Gets the Pango::FontFace representing the selected font group details (i.e. family, slant, weight, width, etc).
If the selected font is not installed, returns 0.
0. The returned object is owned by fontchooser and must not be modified or freed. | Glib::RefPtr<Pango::FontFamily> Gtk::FontChooser::get_font_family | ( | ) |
Gets the Pango::FontFamily representing the selected font family.
Font families are a collection of font faces.
If the selected font is not installed, returns 0.
0. The returned object is owned by fontchooser and must not be modified or freed. | Glib::RefPtr<const Pango::FontFamily> Gtk::FontChooser::get_font_family | ( | ) | const |
Gets the Pango::FontFamily representing the selected font family.
Font families are a collection of font faces.
If the selected font is not installed, returns 0.
0. The returned object is owned by fontchooser and must not be modified or freed. | int Gtk::FontChooser::get_font_size | ( | ) | const |
The selected font size.
| Glib::ustring Gtk::FontChooser::get_preview_text | ( | ) | const |
Gets the text displayed in the preview area.
| bool Gtk::FontChooser::get_show_preview_entry | ( | ) | const |
Returns whether the preview entry is shown or not.
true if the preview entry is shown or false if it is hidden.
