Is there a difference between a MDI Client, a MDI Container, and a MDI Parent?

As it says, is there any difference between a MDI Client, Parent, or Container?

If they are all the same. Does this mean that all MDI applications cannot be more than 1 nested window deep?

Solution

  • You can have only one MDI parent form, as Microsoft says:

    The Microsoft Windows implementation of the multiple document interface (MDI) does not support nested MDI client windows. In other words, neither an MDI client window nor an MDI child window can have an MDI client window as a child.

    About the terms, in the literature the most common words used are MDI Parent and MDI Child. Since the technology itself is just MDI, you are using Parent for the container and Child for the inside forms.
