44 * @brief A PushButton changes its appearance when is pressed and returns to its original when is released.
46 * By default, a PushButton emits a Button::PressedSignal() signal when the button is pressed, a Button::ClickedSignal() signal when it's clicked.
47 * and a Button::ReleasedSignal() signal when it's released or having pressed it, the touch point leaves the boundary of the button.
