I had a similar problem and I solved it in the following way.
1. Added a Class Interface "WindowResizingNotifier" and add a method
"WindowResized"
2. On Windows' Resized event used the following code:
Dim i As Integer
For i = 0 To Self.ControlCount-1
If Self.Control(i) IsA WindowResizingNotifier then
WindowResizingNotifier( Self.Control(i)).WindowResized
End If
Next
3. If you have LiveResize set on the Window you can use:
If Me.LiveResize Then
Dim i As Integer
For i = 0 To Self.ControlCount-1
If Self.Control(i) IsA WindowResizingNotifier then
WindowResizingNotifier( Self.Control(i)).WindowResized
End If
Next
End If
4. On my Custom Controls I set the Interface to
"WindowResizingNotifier" and added the method "WindowResized". On this
method I do whatever I want.
So, everytime the window resizes, it notifies all controls that
implements the "WindowResizingNotifier" interface.
