 Posted: Sat Dec 13, 2003 8:33 pm Post subject: Placement of a message dialog |
 |
|
Is there any way to place message dialogs exactly where you want them in
relation to your application?
Also, taking it a step further, is it possible to place VCL components
SaveDialog and OpenDialog where you want to in relation to your form?
Thanks
Daryl

The only thing the VCL has available for that is MessageDlgPos().

Not directly, no. You would have to use the dialog's OnShow event to
manually move the parent window via the Win32 API SetWindowPos() function,
ie:
void __fastcall TForm1::OpenDialog1Show(TObject *Sender)
{
::SetWindowPos(GetParent(OpenDialog1->Handle), NULL, SomeX, SomeY,
0, 0, SWP_NOSIZE | SWP_NOZORDER);
}

This is one way of doing that
void __fastcall TForm1::OpenDialog1Show(TObject *Sender)
{
TRect rect;
HWND H = GetParent(dynamic_cast<TOpenDialog*>(Sender)->Handle);
GetWindowRect(H, &rect);
MoveWindow(H,
0,
0,
rect.right - rect.left,
rect.bottom - rect.top,
true);
Abort();
}

Thanks Rodolfo...
Just one question:
The use of the API call GetParent - Is the call
GetParent(dynamic_cast<TOpenDialog*>(Sender)->Handle);
actually looking for the parent window of TOpenDialog?
I am a little lost because it looks like the window that is being moved is
the dialog window, the one called from the application's form. Looking at
the properties of TOpenDialog it has an owner but there is no method of
setting its parent. I am creating the TOpenDialog component from the heap
at runtime.
Also, I can see that without Abort() it does not work, but why do you need
it?
Thanks

1) From MS:
"The parent window provides the coordinate system used for positioning a
child window."
2) The Abort procedure cancels the WM_NOTIFY message that
Windows sends to its common dialogs. This allows you to
change the position of OpenDialog.
