/**
* @brief Button is a base class for different kind of buttons.
*
* This class provides the disabled property and the clicked signal.
*
- * A ClickedSignal() is emitted when the button is touched and the touch
- * point doesn't leave the boundary of the button.
+ * A ClickedSignal() is emitted when the button is touched and the touch point doesn't leave the boundary of the button.
*
* When the \e disabled property is set to \e true, no signal is emitted.
*
+ * Button provides the following properties which modify the signals emitted:
+ * <ul>
+ * <li>\e autorepeating
+ * When \e autorepeating is set to \e true, a Button::PressedSignal(), Button::ReleasedSignal() and Button::ClickedSignal() signals are emitted at regular
+ * intervals while the button is touched.
+ * The intervals could be modified with the Button::SetInitialAutoRepeatingDelay and Button::SetNextAutoRepeatingDelay methods.
+ *
+ * A \e togglable button can't be \e autorepeating. If the \e autorepeating property is set to \e true, then the \e togglable property is set to
+ * false but no signal is emitted.
+ *
+ * <li>\e togglable
+ * When \e togglable is set to \e true, a Button::StateChangedSignal() signal is emitted, with the selected state.
+ * </ul>
+ *
+ * The button's appearance can be modified by setting properties for the various image filenames.
+ *
+ * The \e background is always shown and doesn't change if the button is pressed or released. The \e button image is shown over the \e background image when the
+ * button is not pressed and is replaced by the \e selected image when the button is pressed. The text label is placed always on the top of all images.
+ *
+ * When the button is disabled, \e background, \e button and \e selected images are replaced by their \e disabled images.
+ *
+ * Is not mandatory to set all images. A button could be defined only by setting its \e background image or by setting its \e background and \e selected images.
