Also, create a Window, instead of a Dialog without a transient parent, which is (noisily) discouraged. Then s/content_area/box/g to match.

|
||
* @Short_description: Create buttons which retain their state
|
||
* @Title: GtkToggleButton
|
||
* @See_also: #GtkButton, #GtkCheckButton, #GtkCheckMenuItem
|
||
*
|
||
* 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.
|
||
*
|
||
* 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 #GtkImage), into the toggle
|
||
* button’s container. (See #GtkButton for more information).
|
||
*
|
||
* The state of a #GtkToggleButton can be set specifically using
|
||
* gtk_toggle_button_set_active(), and retrieved using
|
||
* gtk_toggle_button_get_active().
|
||
*
|
||
* To simply switch the state of a toggle button, use gtk_toggle_button_toggled().
|
||
*
|
||
* # CSS nodes
|
||
*
|
||
* GtkToggleButton has a single CSS node with name button. To differentiate
|
||
* it from a plain #GtkButton, it gets the .toggle style class.
|
||
*

||
* ## Creating two #GtkToggleButton widgets.
