A #GtkToggleButton is a #GtkButton which will remain 'pressed-in' when
|
|
clicked. Clicking again will cause the toggle button to return to its
|
|
normal state.
|
|
</para>
|
|
<para>
|
|
A toggle button is created by calling either gtk_toggle_button_new() or
|
|
gtk_toggle_button_new_with_label(). If using the former, it is advisable to
|
|
pack a widget, (such as a #GtkLabel and/or a #GtkPixmap), into the toggle
|
|
button's container. (See #GtkButton for more information).
|
|
</para>
|
|
<para>
|
|
The state of a #GtkToggleButton can be set specifically using
|
|
gtk_toggle_button_set_active(), and retrieved using
|
|
gtk_toggle_button_get_active().
|
|
</para>
|
|
<para>
|
|
To simply switch the state of a toggle button, use gtk_toggle_button_toggled.
