Form Type

MAIN

The form that will be swapped to as a Main form.

These forms are not usually displayed directly, but serve to provide gadgets for the application’s toolbar and menus for the application’s main menus.

DOCUMENT

Resizable form usually with a view gadget, but no menu bar. All document forms can be floated or un-floated using the right-mouse pop-up menu in the form’s top border.

When it is floating, you can drag the form away from the MDI frame and position it and resize it without constraint.

This allows you to drag the document form away to another screen of a multi-screen configuration.

DIALOG

This is the default type the form will assume if you gives no type when you set up the form.

The default DIALOG form will be non-resizable, floating, and non-docking. You can specify the DOCKING attribute to allow the form to be docked within the application frame.

By default, a docking dialog is displayed floating, and you can interactively dock it. When a dialog is docked it will be resized to match the application frame edge to which it is docked, and so is resizable by default.

The qualifiers LEFT, RIGHT, TOP, and BOTTOM, specify the edge of the application frame to which the dialog form will be docked when first displayed.

BLOCKINGDIALOG

Normal form layout and content, but will block access to all other forms while it is displayed.
