GtkFontButton is another type of specialized button that allows the user to select font parameters that correspond to fonts currently residing on the user s system. Font options are chosen in a font selection dialog that is displayed when the user clicks the button. These options include the font name, style options, and font size. An example GtkFontButton widget is displayed in Figure 4-11.

Figure 4-11. Font selection buttons Font button widgets are initialized with gtk_font_button_new_with_font(), which allows you to specify the initial font. The font is provided as a string in the following format: Family Style Size. Each of the parameters is optional; the default font for GtkFontButton is Sans 12, which provides no style parameters. Family refers to the formal font name such as "Sans", "Serif" or "Arial". Style options can vary between fonts, but they normally include "Italic", "Bold" and "Bold Italic". If you choose a font style of Regular, no font style will be specified. The size is point size of the text to be shown, such as "12" or "12.5".

Listing 4-11 creates a GtkFontButton widget that is initialized with a font of "Sans Bold 12". When the chosen font in the button is changed, the new font is applied to a GtkLabel widget packed below the font button. Listing 4-11. Using the Font Selection Button (fontbuttons.c) #include <gtk/gtk.h> static void font_changed (GtkFontButton*, GtkWidget*); int main (int argc, char *argv[]) { GtkWidget *window, *vbox, *button, *label; PangoFontDescription *initial_font; gtk_init (&argc, &argv);

The code in Listing 4-11 gives the first sampling of the PangoFontDescription type that you have run across. The PangoFontDescription structure is used to parse font style strings. You can create a new font description from a font string such as "Sans Bold 12" by calling pango_font_description_from_string() as follows: initial_font = pango_font_description_from_string ("Sans Bold 12"); gtk_widget_modify_font (label, initial_font); After creating a font description, gtk_widget_modify_font() can be called to set the font of the widget s text. This function will edit the font description object stored by the widget s GtkStyle property. In Listing 4-11, the label s text was set to the font stored by the GtkFontButton when the font-set signal was emitted. You can retrieve the whole font description string stored by the font button with gtk_font_button_get_font_name(), which was used to retrieve the font string displayed by the label. The returned string should never be modified or freed. const gchar* gtk_font_button_get_font_name (GtkFontButton *button); In Listing 4-11, the new font style was applied to the GtkLabel. However, if you set gtk_font_button_set_use_font() and gtk_font_button_set_use_size() to TRUE, the font button will use the font family and size when rendering its text. This allows the user to preview the text in the font button. This is turned off for font buttons by default. void gtk_font_button_set_use_font (GtkFontButton *button, gboolean use_font); void gtk_font_button_set_use_size (GtkFontButton *button, gboolean use_size);
