Hi

I have a problem that I hope that some of you can help me with.

How do I set the active MDI child of a form ???

I have a form (Form1) with FormStyle=fsMDIForm and two other forms (Form2 and Form3) both with FormStyle=fsMDIChild - they are MDIChilds of Form1. I want to be able to change the ActiveMDIChild of Form1 to say Form2 - how do I do that. If there is no controls on Form2 it is easy done with Form2.SetFocus, but if there is some controls on Form2 Form2.SetFocus just called SetFocus of the ActiveControl of Form2 and Form2 will not nessacary become the ActiveMDIChild of Form1.

There must be a way to change the ActiveMDIChild of Form1, even though the form that you want to become the ActiveMDIChild has some controls on itself. Right now I cheat to do it ...

var
  AWC : TWinControl;

...

AWC := Form2.ActiveControl;
Form2.ActiveControl := nil;
Form2.SetFocus;
Form2.ActiveControl := AWC;

... but cant anyone tell me a better way to do it ???

Thanx Steff

Hello Steff,

If there are only two forms, and you don't add any other Child forms you can use NameOfMDIForm.Next; which will center the focus on the next form, and if the focus is on Form1MDIChild, the focus would be on Form2MDIChild, no matter if there are other controls on the form... This is a solution if there are only two MDIChold Forms...remmeber that!

Hey Steff, How R Ya doing?

A little research and I think this would it...I tried it here and it works, now it's your turn...
(*****************************)
Form2.BringToFront;
Form3.BringToFront;
NameOfMDIChild.BringToFront;
(*****************************)
If you set the BringToFront on the MDIForm like(MDIForm.BringToFront) it will become the top control of all windows, but when you set the BringToFront of a MDIChild then it becomes the top form only in the MDIForm so this way trick should work...

Regards,
Viktor Ivanov
