- * @brief Button is a base class for different kind of buttons.
+ * @brief Button is a base class for different kinds of buttons.
*
* This class provides the disabled property and the clicked signal.
*
* 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.
+ * 'Visual' describes not just traditional images like png, bmp but refers to whatever is used to show the button, it could be a color, gradient or some other kind of renderer.
+ *
+ * The button's appearance can be modified by setting properties for the various visuals/images.
+ *
+ * It is not mandatory to set all visuals. A button could be defined only by setting its \e background visual or by setting its \e background and \e selected visuals.
*
- * 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.
+ * The \e button visual is shown over the \e background visual.
+ * When pressed the unselected visuals are replaced by the \e selected visual. The text label is always placed 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.
+ * When the button is disabled, \e background, \e button and \e selected visuals are replaced by their \e disabled visuals.
*
- * Is not mandatory 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.
