Sub Application (Click)

A sub application or subapp is another display window that can run another frame at the same time as the main window's frame. They can also run external frames saved as ccn files. Subapps have various settings, and may or may not have a border, caption title, or close button. They can also be set as modal, which pauses the main window and all other subapps until the modal subapp is closed; this is generally used for custom dialog boxes.

Subapps can be set to have access to global values or strings, and can have a size different than the frame they display.

In Multimedia Fusion 2 Developer, subapps can be docked, which makes it easy to develop MDI applications.
