Detailed Description

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.

When the disabled property is set to true, no signal is emitted.

Button provides the following properties which modify the signals emitted:

The button's appearance can be modified by setting properties for the various image filenames.

The background is always shown and doesn't change if the button is pressed or released. The button image is shown over the background image when the button is not pressed and is replaced by the selected image when the button is pressed. The text label is placed always on the top of all images.

When the button is disabled, background, button and selected images are replaced by their disabled images.

It's not mandatory to set all images. A button could be defined only by setting its background image or by setting its background and selected images.

Signals | Signal Name | Method | |------------------|-----------------------------| | pressed | PressedSignal() | | released | ReleasedSignal() | | clicked | ClickedSignal() | | stateChanged | StateChangedSignal() |
