You can perform some more detailed actions using dialogs. Simple single-form dialogs, as well as multiple-form-tabbed dialogs, describe various contexts of the subject they serve.

The Properties dialogs are implemented as tabbed dialogs. Use the OK button to introduce all changes made in the dialog and to close it. Use the Cancel button to discard all changes made in the dialog and to close it. Use the Apply button to introduce all changes made in the dialog and to keep the dialog open. In the last case the OK button is replaced by the Close button (it can be used to close the dialog) and the Cancel and Apply buttons become disabled. Any subsequent change made in the dialog enables the Apply button again.
