*
* Dialog provides a dialog-like widget that can be used to display additional
* information.
*
* Dialog uses the plasma theme, and usually has no window decoration. It's meant
* as an interim solution to display widgets as extension to plasma applets, for
* example when you click on an applet like the devicenotifier or the clock, the
* widget that is then displayed, is a Dialog.
