System Modal Dialog

A system modal dialog is a system-level dialog. When launched by an application, it is fixedly centered on the desktop and its position is independent of the source application. Before the user finishes interacting with the system modal dialog, the entire system becomes modal, meaning no other operations can be performed.

Application Modal Dialog

An application modal dialog takes effect only within the application. When launched by an application, it is displayed centered in the application screen. Before the user finishes interacting with it, the application screen that launched the dialog becomes modal, preventing any operations within the application. Other screens are not affected by the application modal dialog and can be operated normally.
