gtk_button_new ()

GtkWidget *
gtk_button_new (void);

GtkWidget *
gtk_button_new_with_label (const gchar *label);

gtk_button_new_with_mnemonic ()

GtkWidget *
gtk_button_new_with_mnemonic (const gchar *label);

Creates a new GtkButton containing a label. If characters in label are preceded by an underscore, they are underlined. If you need a literal underscore character in a label, use '__' (two underscores). The first underlined character represents a keyboard accelerator called a mnemonic. Pressing Alt and that key activates the button.

gtk_button_new_from_stock ()

GtkWidget *
gtk_button_new_from_stock (const gchar *stock_id);

Creates a new GtkButton containing the image and text from a stock item. Some stock ids have preprocessor macros like GTK_STOCK_OK and GTK_STOCK_APPLY.

If stock_id is unknown, then it will be treated as a mnemonic label (as for gtk_button_new_with_mnemonic()).

gtk_button_get_label ()

const gchar *
gtk_button_get_label (GtkButton *button);

Fetches the text from the label of the button, as set by gtk_button_set_label(). If the label text has not been set the return value will be NULL. This will be the case if you create an empty button with gtk_button_new() to use as a container.

gtk_button_set_label ()

void
gtk_button_set_label (GtkButton *button,
                      const gchar *label);

This will also clear any previously set labels.

gboolean
gtk_button_get_use_stock (GtkButton *button);

Returns whether the button label is a stock item.

gtk_button_set_use_stock ()

gtk_button_get_use_underline ()

gboolean
gtk_button_get_use_underline (GtkButton *button);

Returns whether an embedded underline in the button label indicates a mnemonic. See gtk_button_set_use_underline().

void
gtk_button_set_use_underline (GtkButton *button,
                              gboolean use_underline);

                               gboolean focus_on_click);

Sets whether the button will grab focus when it is clicked with the mouse. Making mouse clicks not grab focus is useful in places like toolbars where you don't want the keyboard focus removed from the main area of the application.

Since: 2.4

gtk_button_get_focus_on_click ()

gboolean
gtk_button_get_focus_on_click (GtkButton *button);

Returns whether the button grabs focus when it is clicked with the mouse. See gtk_button_set_focus_on_click().

void
gtk_button_set_image (GtkButton *button,
                      GtkWidget *image);

Set the image of button to the given widget. Note that it depends on the “gtk-button-images” setting whether the image will be displayed or not, you don't have to call gtk_widget_show() on image yourself.

Since: 2.6

gtk_button_get_image ()

GtkWidget *
gtk_button_get_image (GtkButton *button);

Gets the widget that is currenty set as the image of button . This may have been explicitly set by gtk_button_set_image() or constructed by gtk_button_new_from_stock().

void
gtk_button_set_image_position (GtkButton *button,
