Description

GtkToolButtons are GtkToolItems containing buttons.

Use gtk_tool_button_new() to create a new GtkToolButton. Use gtk_tool_button_new_with_stock() to create a GtkToolButton containing a stock item.

The label of a GtkToolButton is determined by the properties "label_widget", "label", and "stock_id". If "label_widget" is non-NULL, then that widget is used as the label. Otherwise, if "label" is non-NULL, that string is used as the label. Otherwise, if "stock_id" is non-NULL, the label is determined by the stock item. Otherwise, the button does not have a label.

The icon of a GtkToolButton is determined by the properties "icon_widget" and "stock_id". If "icon_widget" is non-NULL, then that widget is used as the icon. Otherwise, if "stock_id" is non-NULL, the icon is determined by the stock item. Otherwise, the button does not have a label.

GtkToolButton

typedef struct _GtkToolButton GtkToolButton;

The GtkToolButton struct contains only private. It should only be accessed with the function described below.


gtk_tool_button_new ()

GtkToolItem* gtk_tool_button_new            (GtkWidget *icon_widget,
                                             const gchar *label);

Creates a new GtkToolButton using icon_widget as icon and label as label.

icon_widget : a widget that will be used as icon widget, or NULL
label : a string that will be used as label, or NULL
Returns : A new GtkToolButton

Since 2.4


gtk_tool_button_new_from_stock ()

GtkToolItem* gtk_tool_button_new_from_stock (const gchar *stock_id);

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

It is an error if stock_id is not a name of a stock item.

stock_id : the name of the stock item
Returns : A new GtkToolButton

Since 2.4


gtk_tool_button_set_label ()

void        gtk_tool_button_set_label       (GtkToolButton *button,
                                             const gchar *label);

Sets label as the label used for the tool button. The "label" property only has an effect if not overridden by a non-NULL "label_widget" property. If both the "label_widget" and "label" properties are NULL, the label is determined by the "stock_id" property. If the "stock_id" property is also NULL, button will not have a label.

button : a GtkToolButton
label : a string that will be used as label, or NULL.

Since 2.4


gtk_tool_button_get_label ()

const gchar* gtk_tool_button_get_label      (GtkToolButton *button);

Returns the label used by the tool button, or NULL if the tool button doesn't have a label. or uses a the label from a stock item. The returned string is owned by GTK+, and must not be modified or freed.

button : a GtkToolButton
Returns : The label, or NULL

Since 2.4


gtk_tool_button_set_use_underline ()

void        gtk_tool_button_set_use_underline
                                            (GtkToolButton *button,
                                             gboolean use_underline);

If set, an underline in the label property indicates that the next character should be used for the mnemonic accelerator key in the overflow menu. For example, if the label property is "_Open" and use_underline is TRUE, the label on the tool button will be "Open" and the item on the overflow menu will have an underlined 'O'.

Labels shown on tool buttons never have mnemonics on them; this property only affects the menu item on the overflow menu.

button : a GtkToolButton
use_underline : whether the button label has the form "_Open"

Since 2.4


gtk_tool_button_get_use_underline ()

gboolean    gtk_tool_button_get_use_underline
                                            (GtkToolButton *button);

Returns whether underscores in the label property are used as mnemonics on menu items on the overflow menu. See gtk_tool_button_set_use_underline().

button : a GtkToolButton
Returns : TRUE if underscores in the label property are used as mnemonics on menu items on the overflow menu.

Since 2.4


gtk_tool_button_get_stock_id ()

const gchar* gtk_tool_button_get_stock_id   (GtkToolButton *button);
