Good way to resize form components on form resize?

[CADTenchy]

Hi,

I have a simple form with a few basic components on it.
I've put some size restraints on resizing the form, to stop it being resized to a stupid size, small or large.

To keep the components looking how I want them relative to the form size, I've used the code below.

Is this a good way to do it? I'm concerned about appearances depending on PC setup, only got my laptop to test on right now.

procedure TSDIAppForm.FormResize(Sender: TObject);
begin
ColumnListBox1.Width := ClientWidth-10;
ColumnListBox1.Height := ClientHeight-90;
Edit2.Width := ClientWidth-100;
Button3.Left := ClientWidth-240;
Button3.Top := ClientHeight-48;
Button2.Top := Button3.Top; 
end;

Use the Align property of components. The Client setting will force a component to fill it's available surrounding area. Separate blocks of components using Panel components. I don't have Delphi on this computer, so I can't remember what it's called, but it's on the Additional tab and is a divider of sorts.

If a component doesn't have an Align property (eg. TLabel), put them on a Panel, or use TStaticLabel.

The Align property also has a Custom setting, that generates an event where you can manually plug in figures, but I don't have any experience using it.

Futher to what Griffyn has said, you can also use the Anchors property to ensure the left/top/right/bottom of your control always stays in the same position relative to its parent.
This should give you the behaviour you're looking for without the need for any code.
