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().
typedef struct _GtkFontSelection GtkFontSelection;
The GtkFontSelection struct contains private data only, and should only be accessed using the functions below.
GtkWidget* gtk_font_selection_new (void);
Creates a new GtkFontSelection.
| Returns : | a new GtkFontSelection. |
GdkFont* gtk_font_selection_get_font (GtkFontSelection *fontsel);
gtk_font_selection_get_font is deprecated and should not be used in newly-written code.
Gets the currently-selected font.
fontsel : |
a GtkFontSelection. |
| Returns : | the currently-selected font, or NULL if no font is selected. |
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().
|
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.
|
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. |
void gtk_font_selection_set_preview_text (GtkFontSelection *fontsel, const gchar *text);
Sets the text displayed in the preview area.
fontsel : |
a GtkFontSelection. |
text : |
the text to display in the preview area. |
"font-name" property"font-name" gchar* : Read / Write
The X string that represents this font.
Default value: NULL
"preview-text" property"preview-text" gchar* : Read / Write
The text to display in order to demonstrate the selected font.
