//! @class SpacePushButton
//! A QPushButton which can be triggered by pressing (actually: releasing) Space when it has focus.
//! To use this class in the QtCreator UI designer, add a regular QPushButton to the UI,
//! then right-click on it and change its type to SpacePushButton.
//! Then it makes sense to put this button into a useful GUI tab order.
