Replaced QDesktopWidget::availableGeometry() and QDesktopWidget::screenGeometry() Calls
In Qt-5.14.0 the compiler complained about replacing QDesktopWidget::availableGeometry() and QDesktopWidget::screenGeometry() calls.
The replacement code is based on functionality which should be, according to the documentation, available since Qt-5.0.
