Dialog Windows

Dialogs can be modal, in which case the user is required to provide necessary information before work in the main window can continue, or modeless. Modeless dialogs do not prevent the user from interacting with any of the other windows in the application.

Qt provides a set of ready-made dialogs for file, font, color-selection and more.
