Usage and examples
In the MDI mode, you can run several applications as child ones within one parent container:

Here you can read more about MDI mode.
By default, QX_MDI is not set and all applications are run in the SDI mode.
There are two ways to enable the MDI mode:
-
by defining the QX_MDI environment variable in inet.env with any non-empty value (though we recommend setting it to 1):
QX_MDI = 1
- by calling ui.Interface.setType("Container") in your 4gl program (refer here to get the details).
QX_MDI applies at runtime and, if necessary, is set in inet.env and in environ.bat (for the command line environment).
You can set QX_MDI together with QX_MENU_WINDOW and QX_MENU_WINDOW_NEW_CHILD to enable more profound MDI functionality.
