Hi,
Is there any way to catch when some form changed it's title text ? I want to catch such changes inside main form.
Is it possible via LCL ?
tnx.

You can override RealSetText in your forms, and do there whatever is required. From there you can notify your main form directly, or you can trigger a new OnCaptionChanged event, for which your main form can provide an event handler.

you can add a message handler CM_TEXTCHANGED for your form.
Best regards,

tnx, but maybe I've asked it wrong (or you misunderstood) : I want to catch when some form (except application main form) changes title (non modal forms) inside main form handler.
So, when my Form2 changes title MainForm should know about it. If I have to add message handler to each of my forms, then it will take some amount of time .... that's the reason why I'm asking this - catch title change without adding any handler into forms, except main form.

As I mentioned in my previous posts:
I don't want to touch forms code, only main form code can be touched.So it seem that such thing isn't possible in lcl.
