Resing a window

[Silvio.Falconi]

I have a window (Main) where I insert a dialog with style .or. 4

on this dialog I put a tPanel (oPanel) and in this panel many btnbmps.

when I resize this window the procedure should reduce all the btnbmps that are inside up to a min / max that I set with

oWndMain:aMinMaxInfo := { nil, nil, nil, nil, 878, 570, nil, nil }

I talk of 450 btnbmps and on widow there is also a ribbonbar

How I can resolve...
I saw on Microsoft there is a control of window ( like winword) reduce the window with all control inside , on fw this is possible ?

resolved thanks to Frank Demont ( I found a oldest source test on this forum after 3 Hour od research)
I think this method must be inserted on Window control as a Clausole type ZOOMWINDOW
it run really good !!!
