  A Pango::FontFace representing the selected font group details. The returned object is owned by fontsel and must not be modified or freed.

Glib::RefPtr<const Pango::FontFace> Gtk::FontSelection::get_face | ( |  | ) | const

Gets the Pango::FontFace representing the selected font group details (i.e. family, slant, weight, width, etc).

Since gtkmm 2.14:

Returns:
  A Pango::FontFace representing the selected font group details. The returned object is owned by fontsel and must not be modified or freed.

TreeView* Gtk::FontSelection::get_face_list | ( |  | ) |

This returns the Gtk::TreeView which lists all styles available for the selected font.

For example, 'Regular', 'Bold', etc.

Since gtkmm 2.14:

Returns:
  A Gtk::Widget that is part of fontsel.

const TreeView* Gtk::FontSelection::get_face_list | ( |  | ) | const

  A Gtk::Widget that is part of fontsel.

Glib::RefPtr<Pango::FontFamily> Gtk::FontSelection::get_family | ( |  | ) |

Gets the Pango::FontFamily representing the selected font family.

Since gtkmm 2.14:

Returns:
  A Pango::FontFamily representing the selected font family. Font families are a collection of font faces. The returned object is owned by fontsel and must not be modified or freed.

Glib::RefPtr<const Pango::FontFamily> Gtk::FontSelection::get_family | ( |  | ) | const

Gets the Pango::FontFamily representing the selected font family.

Since gtkmm 2.14:

Returns:
  A Pango::FontFamily representing the selected font family. Font families are a collection of font faces. The returned object is owned by fontsel and must not be modified or freed.

TreeView* Gtk::FontSelection::get_family_list | ( |  | ) |

This returns the Gtk::TreeView that lists font families, for example, 'Sans', 'Serif', etc.

Since gtkmm 2.14:

  A Gtk::Widget that is part of fontsel.

const TreeView* Gtk::FontSelection::get_family_list | ( |  | ) | const

This returns the Gtk::TreeView that lists font families, for example, 'Sans', 'Serif', etc.

Returns:
  A Gtk::Widget that is part of fontsel.

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().

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

This returns the Gtk::Entry used to display the font as a preview.

Since gtkmm 2.14:

Returns:
  A Gtk::Widget that is part of fontsel.

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

This returns the Gtk::Entry used to display the font as a preview.

Returns:
  A Gtk::Widget that is part of fontsel.

Glib::ustring Gtk::FontSelection::get_preview_text | ( |  | ) | const

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.
