Thanks.

Hi Borgo,

If I understood your question right then this is probably what you're looking for.

I've used this technique for some years, it comes from a delphi book "Delphi How-to".



procedure TResizer.FormCreate(Sender: TObject);
begin
  BH := Height;
  BW := Width;
end;

procedure TResizer.FormResize(Sender: TObject);
var
  AH, AW: Word;
  R: TRect;
  I: Integer;
begin
  AH := Height;
  AW := Width;
  for I := 0 to ComponentCount - 1 do
  if Components[I] is TControl then
  begin
    R := TControl(Components[I]).BoundsRect;
    R.Left := MulDiv(R.Left, AW, BW);
    R.Top := MulDiv(R.Top, AH, BH);
    R.Right := MulDiv(R.Right, AW, BW);
    R.Bottom := MulDiv(R.Bottom, AH, BH);
    TControl(Components[I]).BoundsRect := R;
  end;
  BH := Height;
  BW := Width;
end;

Hope this helps.
Good luck
Bruintje

I have a panel that resizes all the components on it when it's resized.

Bryan 7:  Please send me you panel ? Is it free and with source ? I'll use it in the application which  I'll do for my next exam.

Viktornet: I haven't tried your component yet. I'll inform you early. Thanks again.

Bruintje: Yes it works. But is not a too simple solution ? What do you think about ? Thank you.

Hi Borgo,

Hum.. "Keep It Simple Stupid".
Learned the hard way that doing things simple is a way of keeping up in real life. If you have done that long enough you can buy yourself the time to create more beautiful(complex) things, making life worth living.

Bruintje.

Hi again,

In addition to my previous comment, I think you should use the solution that's most suitable for the needs. If you had to make only some components resizing at a given action (couldn't think of an example, maybe zooming? :) )then it would be simpler to use a component that turns on or off the resizing capabillities of selected components.
