The information in this article applies to:
- Microsoft Visual FoxPro for Windows, version 6.0
-------------------------------------------------------------------------------
SYMPTOMS
========
You can use the AlwaysOnTop property of a Visual FoxPro form in conjunction with
a TopLevel form to create an application that prevents other windows from
covering the applications window. Changing the AlwaysOnTop property at run-time
changes the behavior of the form, but querying the property value always returns
.F. This behavior only exists when the ShowWindow property of the form is set to
2 - As TopLevel Form.
RESOLUTION
==========
You can use a custom property and an AlwaysOnTop Assign method to work around
this problem. The following code uses a custom form property called
AlwaysOnTop_Actual to store the actual setting of the AlwaysOnTop property of
the form. The value of this custom property changes in the AlwaysOnTop_Assign
method:
PUBLIC ox
ox = NewObject("test")
ox.Show
?ox.AlwaysOnTop_Actual
ox.AlwaysOnTop = .F.
?ox.AlwaysOnTop_Actual
ox.AlwaysOnTop = .T.
?ox.AlwaysOnTop_Actual
DEFINE CLASS test AS form
ShowWindow = 2
AlwaysOnTop = .T.
AlwaysOnTop_Actual = .T.
PROCEDURE AlwaysOnTop_Assign
LPARAMETERS vNewVal
This.AlwaysOnTop_Actual = vNewVal
THIS.AlwaysOnTop = m.vNewVal
ENDPROC
ENDDEFINE
STATUS
======

ox.AlwaysOnTop = .F.
