 |
|
When I use ShowModal to display a form, a separate icon for the form appears
on the taskbar next to the application's icon. Is there some way to prevent
this?
I'm doing this:
TMyForm *Form = new TMyForm(Forms::Application);
Form->ShowModal();
Thanks,
Bruce

Very interesting. I thought that required an API call to
CreateWindowEX. I wonder if it creates other problems ... ?

If you want the form currently executing to be the owner of
the new form:
TMyForm *Form = new TMyForm( this );

Thanks for the reply JD,
Ok, I'll level...I don't really have a currently executing form. I do have a
hidden main window (I've tried using that as the owner, with the same
results). Here is the kicker, though--while I do create an application
object, call Application->Initialize(), and call CreateForm() for the form,
I don't actually call Application->Run()! This app is an OWLNext app which
is using VCL forms as well. Do you suppose this might have something to do
with it?
Regards,
Bruce

If the form has been created, did you try Form2->ShowModal()
without trying to 'new' it?

It seems obviouse to me that this would be an issue. It
doesn't mean that you can't do what you want, it just means
that fewer people have worked with it (which I haven't) and
thus fewer people who can help.

Yes, with the same result. |
As to not using Application->Run(), at a cursory glance at Forms.pas, I
didn't see anything obvious in Run() that would explain it. I'm wondering
what VCL assigns to the default main form (the first one that is created) as
its parent? The application object?

I thinking that it must be the DeskTop because the Parent is
responsible for a number of things that can loosly be thought
of as where the object lives. Now the Owner, although similar
in nature is a different animal and the owner of the main form
is the application.
So ... I would suggest that you next try to remove the form
from the autocreate and 'new' it using '( this )' and then try
setting it's Parent to the DeskTop (NULL).
If that fails, have a look at win32 API CreateWindowEX. It
might, just might do the trick.
The last possible solution that I can offer is a bit of
a 'hack'. Change the main form to display as a something like
a desktop icon which would allow you to discard your current
technique of hiding the main form. You could even copy a
portion of the screen and paint that to the captionless form.
There is one thing that I don't understand though: if you need
a form, why not use the main form?
