41 * @brief Button is a base class for different kind of buttons.
43 * This class provides the dimmed property and the clicked signal.
45 * A ClickedSignal() is emitted when the button is touched and the touch
46 * point doesn't leave the boundary of the button.
48 * When the \e dimmed property is set to \e true, no signal is emitted.
