Q: Newbe quiz. MDI Forms...

[Martin Arvidsson, Visual Systems AB]

Hi!

Before i am going to write my app, i need to ask two questions.

1. Is the MDI about to dissapear? What style of programing should you apply?

2. Did a little experiment with MDI forms. Created a MDI parent with menus
and all (from the template) Created a child. How can i from the child set
text in the statusPanel at the bottom of the MDI parent from the child?

Regards
Martin

Martin,

MDI forms are not going anywhere.

As for updating the status on the MDI parent, you should pass to the
constructor (or pass through some method or property) a class which allows
you to set the text. So, in this case, when creating the children, you
would pass a reference to the status bar (or a class that has a method that
will change the statusbar text for you) to your child class. Your child
class would then store that reference and make a call when it wanted to
update the statusbar.

You could also expose an event on your child class which the parent
would hook up to and then update the status bar on its own when the event is
fired.

Hope this helps.
