Ap Mdi forms we can change to form but when valid form is active

[eldonfsr]

Hi i have MDi Appe i have several form open or windows but when i ask or validate if form is active always sad not active..

if FormEdit.Active then neve goin true this always form... 
  ShowMessage('Can close App form edit is open');
end else begin
  Self.Close;
end
 There is way to validate that i know form is active when we are interactive with it..
if FormEdit <> nil    could only this option to do that...

Code: Pascal  [Select][+][-]

1. var
2.   ActiveChild:TCustomForm;  // in the MDIForm
3. begin
4.   ActiveChild := self.ActiveMdiChild; // does what it says
5. //....
6. // or something like..
7.   Caption := ActiveMdiChild.Classname;

If you programmed it correctly there is also feedback because the color of the child's titlebar changes on activation.
There can be only one child active at a time, so maybe you asked the wrong question?
