I worked with the example of FormMover.Odcl
And I saw that some controls of they move with the width of the form and other not.
Why don't I get to reproduce this?
Change the "Use Left From Right" and the other similar properties to = 1.
Barry is correct, but the easiest way to change these properties is via the Properties dialog's Geometry tab (right click on a control and select 'Properties').
I tested this in OpenDcl 4.1.2.2 it doesn't work in the editor.
But this works well at runtime.
I don't think that 4.0 had the real-time feedback preview that 5.0 has.
