\inqmlmodule QtQuick.Controls
\brief An abstract representation of a checkable control with a label
\qmlabstract
\internal
A checkable control is one that has two states: checked (on) and
unchecked (off). AbstractCheckable encapsulates the basic behavior and
states that are required by checkable controls.
Examples of checkable controls are RadioButton and
CheckBox. CheckBox extends AbstractCheckable's behavior by adding a third
state: partially checked.

Emitted whenever the control is clicked.

This property is \c true if the control is being pressed.
