Use a gadget for the button, and for the indicator. A complication here is that GtkCheckButton (and GtkRadioButton) have a totally different appearance depending on the ::draw-indicator property. If an indicator is not required, we just reuse the GtkButton gadget. This mostly works; some minor sizing issues left, e.g. cranking up the indicator-size causes the checkbutton grid in testgtk to overlap.

* @Title: GtkCheckButton
|
|
* @See_also: #GtkCheckMenuItem, #GtkButton, #GtkToggleButton, #GtkRadioButton
|
|
*
|
|
* A #GtkCheckButton places a discrete #GtkToggleButton next to a widget,
|
|
* (usually a #GtkLabel). See the section on #GtkToggleButton widgets for
|
|
* more information about toggle/check buttons.
|
|
*
|
|
* The important signal ( #GtkToggleButton::toggled ) is also inherited from
|
|
* #GtkToggleButton.

|
*
|
|
* # CSS nodes
|
|
*
|
|
* |[<!-- language="plain" -->
|
|
* checkbutton
|
|
* ╰── check
|
|
* ]|
|
|
*
|
|
* A GtkCheckButton with indicator (see gtk_toggle_button_set_mode()) has a
|
|
* main CSS node with name checkbutton and a subnode with name check.
|
|
*
|
|
* |[<!-- language="plain" -->
|
|
* button.check
|
|
* ╰── [check]
|
|
* ]|
|
|
*
|
|
* A GtkCheckButton without indicator changes the name of its main node
|
|
* to button and adds a .check style class to it. The subnode is invisible
|
|
* in this case.
