Return values from windows

[Mahanimann]

Hi,
I need to receive values from windows. F.ex. the user chooses a record in a
browse pop-up window, the pop-up window closes, and the calling window
receives the value chosen (can be of any datatype).
With my very limited knowledge about Xailer/xHarbour I have solved this
(i.e. to get a return value from a window) with this:
CLASS TForm FROM XForm
DATA xReturnVal_From_PopUp_Window
END CLASS
The parent (oParent) in all pop-up windows are set to the calling window.
When the pop-up window closes, it puts the return value into
::oParent:xReturnVal_From_PopUp_Window.
This works fine, but there must be a neater way to do this? (Tweaking with
:nModalResult gave me only trouble )
Thanks for any reply,
Paal

Paal,
Use the the property TForm:lHideOnClose. See the docs for further
information.

Paal,
Use the the property TForm:lHideOnClose. See the docs for further

Is TForm:Close() with TForm:lHideOnClose == .F. exactly the same as
TForm:End()?

Almost the same, but not exactly equal. TForm:Close() send the message
WM_CLOSE to the form, and the form closes and destroys itself, while
TForm:End() simply destroys the form.
IOW, it's desirable to call always :Close(), excepting if you are setting
:lHideOnClose to .T. and you have to destroy the form after it has been
closed.

Ok. I call :End(), maybe this is why my app is chewing up memory. Child
windows do not release much memory when :End()'ed. I will check it out
tomorrow.
