Hi folks.

Do you know an event or any other trick I could use when a form re-gains control, i.e. is focused again ?
Events OnShow, OnActivate fire only once after OnCreate. The form is brought to the foreground by the means of a MyForm.BringToFront once a OtherForm.ShowModal returns. The reason is because the WindowsCE forms stack control seems to be rubbish. The form I want to manage control is also the main form of the program.

Thanks,
Antonio.

It depends on what you want to do with Form1 while Form2 is showing. You can put a line in Form2's OnActivate event to bring Form1 to the front but you will not be able to do anything in Form1 until Form2 is closed.

Cheers.

Bob

These were my candiates as well.

Sorry, I don't know how WinCE behaves in this case. But when ShowModal returns, you can do whatever is needed - e.g. invoke FormActivate or whatever handler contains your specific code.

The form I want to manage control is also the main form of the program.

In a Delphi program I send the main form user-defined messages, whenever certain informations have been changed by other code and must be reflected in my main form.

Very simple: when yo exit a modal displayed form you are not always sure to have on the screen the form which displayed the closed one. That's why I guess that forms stack is not very well managed But when ShowModal

returns, you can do whatever is needed - e.g. invoke FormActivate or whatever handler contains your specific code.

Yes, but the problem is that this main form shows two dozens of other forms ! It's easy to gain control after ShowModal returns but the code has to be repeated as many times as ther are forms to process.

I'm used to send messsages as well. Again, it supposes the (almost) same code to be reproduced for every form.

I think I'm going to implement a timer wich will periodically launch the code. I'll just disable it on places where the program must not be interrupted. In my mind I was thinking to use those moments where the operator comes back to the main menu to start another operation which ensures that nothing else important is guing on, like one form event Thanks anyway
I think

These are two problems. One is the Z order maintenance, and another one which messages are sent. I only know from working on one program (C++), that WinCE differs from traditional Windows behaviour.

AFAIR the LCL maintains a forms list in Z order (Application.Forms?), which may be useful to establish the wanted Z order.

I can aknowledge. This strange behaviour is what we see. This the reason why on ShowModal return a Self.BringToFront is performed and Z order stack problems are solved
