"font" GdkFont* : Read "font-name" gchar* : Read / Write "preview-text" gchar* : Read / Write
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
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. |
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);
The text returned is the preview text used to show how the selected font looks.
Gets the text displayed in the preview area.
fontsel : |
a GtkFontSelection |
Returns : | pointer to the preview text string. This string points to internally allocated storage in the widget and must not be freed, modified or stored. |
void gtk_font_selection_set_preview_text (GtkFontSelection *fontsel, const gchar *text);
The text
is used to show how the selected font looks.
Sets the text displayed in the preview area.
fontsel : |
a GtkFontSelection |
text : |
a pointer to a string |
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 |
Since 2.14
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. |
Since 2.14
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. |
Since 2.14
gint gtk_font_selection_get_size (GtkFontSelection *fontsel);
The selected font size.
fontsel : |
a GtkFontSelection |
Returns : | A gint representing the font size selected, or -1 if not. |
Since 2.14
GtkWidget* gtk_font_selection_get_family_list (GtkFontSelection *fontsel);
This returns the GtkTreeView that lists font families, for example, 'Sans', 'Serif', etc.
fontsel : |
a GtkFontSelection |
Returns : | A GtkWidget. |
Since 2.14
GtkWidget* gtk_font_selection_get_preview_entry (GtkFontSelection *fontsel);
This returns the GtkEntry used to display the font as a preview.
fontsel : |
a GtkFontSelection |
Returns : | A GtkWidget. |
Since 2.14
GtkWidget* gtk_font_selection_get_size_entry (GtkFontSelection *fontsel);
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. |
Since 2.14
GtkWidget* gtk_font_selection_get_size_list (GtkFontSelection *fontsel);
This returns the GtkTreeeView used to list font sizes.
fontsel : |
a GtkFontSelection |
Returns : | A GtkWidget. |
Since 2.14
"font-name"
