Properties

  "font"                     GdkFont*              : Read
  "font-name"                gchar*                : Read / Write

Description

The GtkFontSelection widget lists the available fonts, styles and sizes, allowing the user to select a font. It is used in the GtkFontSelectionDialog widget to provide a dialog box for selecting fonts.

To set the font which is initially selected, use gtk_font_selection_set_font_name().

To get the selected font use gtk_font_selection_get_font_name().

To change the text which is shown in the preview area, use gtk_font_selection_set_preview_text().

Details

struct GtkFontSelection

struct GtkFontSelection;

The GtkFontSelection struct contains private data only, and should only be accessed using the functions below.

gtk_font_selection_new ()

GtkWidget *         gtk_font_selection_new              (void);

Creates a new GtkFontSelection.

Returns :

 a n ew GtkFontSelection

gtk_font_selection_get_font ()

GdkFont *           gtk_font_selection_get_font         (GtkFontSelection *fontsel);

Warning

gtk_font_selection_get_font has been deprecated since version 2.0 and should not be used in newly-written code. Use gtk_font_selection_get_font_name() instead.

Gets the currently-selected font.

fontsel :

 a GtkFontSelection

Returns :

 A GdkFont.

gtk_font_selection_get_font_name ()

gchar *             gtk_font_selection_get_font_name    (GtkFontSelection *fontsel);

Gets the currently-selected font name.

Note that this can be a different string than what you set with gtk_font_selection_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.

fontsel :

 a GtkFontSelection

Returns :

 A string with the name of the current font, or NULL if no font is selected. You must free this string with g_free().

gtk_font_selection_set_font_name ()

gboolean            gtk_font_selection_set_font_name    (GtkFontSelection *fontsel,
                                                         const gchar *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.

fontsel :

 a GtkFontSelection

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.

gtk_font_selection_get_preview_text ()

const gchar *       gtk_font_selection_get_preview_text (GtkFontSelection *fontsel);

Gets the text displayed in the preview area.

fontsel :

 a GtkFontSelection

Returns :

 the text displayed in the preview area. This string is owned by the widget and should not be modified or freed

gtk_font_selection_set_preview_text ()

void                gtk_font_selection_set_preview_text (GtkFontSelection *fontsel,
                                                         const gchar *text);

Sets the text displayed in the preview area. The text is used to show how the selected font looks.

fontsel :

 a GtkFontSelection

text :

 the text to display in the preview area

gtk_font_selection_get_face ()

PangoFontFace *     gtk_font_selection_get_face         (GtkFontSelection *fontsel);

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

fontsel :

 a GtkFontSelection

Returns :

 A PangoFontFace representing the selected font group details. The returned object is owned by fontsel and must not be modified or freed. [transfer none]

Since 2.14

gtk_font_selection_get_face_list ()

GtkWidget *         gtk_font_selection_get_face_list    (GtkFontSelection *fontsel);

This returns the GtkTreeView which lists all styles available for the selected font. For example, 'Regular', 'Bold', etc.

fontsel :

 a GtkFontSelection

Returns :

 A GtkWidget that is part of fontsel. [transfer none]

Since 2.14

gtk_font_selection_get_family ()

PangoFontFamily *   gtk_font_selection_get_family       (GtkFontSelection *fontsel);

Gets the PangoFontFamily representing the selected font family.

fontsel :

 a GtkFontSelection

Returns :

 A PangoFontFamily 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. [transfer none]

Since 2.14

gtk_font_selection_get_size ()

gint                gtk_font_selection_get_size         (GtkFontSelection *fontsel);

fontsel :

 a GtkFontSelection

Returns :

 A GtkWidget that is part of fontsel. [transfer none]

Since 2.14

gtk_font_selection_get_size_entry ()

This returns the GtkEntry used to allow the user to edit the font number manually instead of selecting it from the list of font sizes.

fontsel :

 a GtkFontSelection

Returns :

 A GtkWidget that is part of fontsel. [transfer none]

Since 2.14

gtk_font_selection_get_size_list ()

GtkWidget *         gtk_font_selection_get_size_list    (GtkFontSelection *fontsel);
