const Entry* Gtk::FontSelection::get_font_entry | ( |  | ) | const

Entry* Gtk::FontSelection::get_font_entry | ( |  | ) |

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().

Glib::PropertyProxy_ReadOnly<Glib::ustring> Gtk::FontSelection::property_font_name | ( |  | ) | const

The string that represents this font.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

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.

Glib::PropertyProxy<Glib::ustring> Gtk::FontSelection::property_font_name | ( |  | ) |

The string that represents this font.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

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.

Glib::PropertyProxy_ReadOnly<Glib::ustring> Gtk::FontSelection::property_preview_text | ( |  | ) | const

The text to display in order to demonstrate the selected font.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

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.

Glib::PropertyProxy<Glib::ustring> Gtk::FontSelection::property_preview_text | ( |  | ) |

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 | ) |

Sets the text displayed in the preview area.

The text is used to show how the selected font looks.

Parameters:

  | text | The text to display in the preview area.
