### Method

# Gtk Labelset_mnemonic_widget

#### Declaration [src]

    void
    gtk_label_set_mnemonic_widget (
      GtkLabel* self,
      GtkWidget* widget
    )

#### Description [src]

Associate the label with its mnemonic target.

If the label has been set so that it has a mnemonic key (using i.e. `gtk_label_set_markup_with_mnemonic()`, `gtk_label_set_text_with_mnemonic()`, `gtk_label_new_with_mnemonic()` or the `GtkLabel:use-underline` property) the label can be associated with a widget that is the target of the mnemonic. When the label is inside a widget (like a `GtkButton` or a `GtkNotebook` tab) it is automatically associated with the correct widget, but sometimes (i.e. when the target is a `GtkEntry` next to the label) you need to set it explicitly using this function.

The target widget will be accelerated by emitting the `GtkWidget::mnemonic-activate` signal on it. The default handler for this signal will activate the widget if there are no mnemonic collisions and toggle focus between the colliding widgets otherwise.
