MDI programs

When opening multiple forms within one running HBasic application they will normally be created as standalone windows on your current desktop. For a complex application if may be more usefule to create all forms of your application as subforms of one big window. We will call this a multiple document interface (MDI) application.To change your current HBasic application to a MDI application execute the following steps.

Open the project window with a mouseclick of the right mouse button on the project entry in the project tree

Select the checkbox named MDI mainwindow

This will open a new source code window and create a new entry in the project tree in the global source section. If you start the interpreter now HBasic will open all form windows within a larger MDI window frame.
