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.
These were my candiates as well.
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.
Sorry, I don't know how WinCE behaves in this case.
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
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.
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
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.
AFAIR the LCL maintains a forms list in Z order (Application.Forms?),
which may be useful to establish the wanted Z order.
