Glib::ustring Gtk::FontSelection::get_font_name | ( | ) | const |
Gets the currently-selected font name.
Note that this can be a different string than what you set with set_font_name(), as the font selection 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.
- Returns:
- A string with the name of the current font, or #
0
if no font is selected. You must free this string with Glib::free().

- Returns:
- A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

bool Gtk::FontSelection::set_font_name | ( | const Glib::ustring & | fontname | ) |
Sets the currently-selected font.
Note that the fontsel needs to know the screen in which it will appear for this to work; this can be guaranteed by simply making sure that the fontsel is inserted in a toplevel window before you call this function.
- Parameters:
-
fontname A font name like "Helvetica 12" or "Times Bold 18".
- Returns:
- #
true
if the font could be set successfully; #false
if no such font exists or if the fontsel doesn't belong to a particular screen yet.
void Gtk::FontSelection::set_preview_text | ( | const Glib::ustring & | fontname | ) |
The text is used to show how the selected font looks.
- Parameters:
-
text A pointer to a string.
