Non-modal AboutDialog
AboutDialog erbjuder ett lätt sätt att visa information om ett program, som dess logotyp, namn, upphovsrätt, webbplats och licens.
Most dialogs in this chapter are modal, that is, they freeze the rest of the application while they are shown. It's also possible to create a non-modal dialog, which does not freeze other windows in the application. The following example shows a non-modal AboutDialog. This is perhaps not the kind of dialog you would normally make non-modal, but non-modal dialogs can be useful in other cases. E.g. gedit's search-and-replace dialog is non-modal.
