icon_widget | a GtkMisc widget that will be used as icon widget, or `NULL`. | [allow-none]

#### Returns

A new GtkToolButton

### 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.

### 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.

#### Parameters

button | a GtkToolButton |
label | a string that will be used as label, or `NULL`. | [allow-none]

Since: 2.4

### gtk_tool_button_get_label ()

    const gchar *
    gtk_tool_button_get_label (GtkToolButton *button);
