Calculate needed size for a TLabel

Ok, here's the problem. I have a label component in a panel. The label is aligned as alClient and has wordwrap enabled. The text can vary from one line to several lines. I would like to re-size the height of the the panel (and the label) to fit all the text.

How do I get the necessary height of a label when I know the text and the width of the panel?

You can use one line of code for this:

label.width := label.canvas.textwidth(label.caption);

or you can set the label's autosize property to true in the object inspector.

If you can align it alTop and keep AutoSize on then TLabel will auto adjust the height after settign the caption.
