How to set TPanel transparent?

Question

When placing the TPanel component in designer, it seems it can not be made transparent? There's an opacity option, but that only deails with animations. I want the panel itself to be fully transparent, so I can see the image underneath. (I want to use the panel as a way of control layout of the controls placed on it)

TPanel has a Windows handle. Controls with windows handles will fight you to the death to remain non-transparent. You'll have to use another control -- TShape? TBevel? TPaintBox? — Nick Hodges, Jul 01 '13 at 15:56
As Slomoto's answer, use a TLayout, or set Fill.Color and Stroke.Color to claNull. — Mike Sutton, Jul 02 '13 at 09:33

Use TLayout or TRectangle instead of TPanel.

Will test later tonight. TLayout sounds promising – Tom Jul 01 '13 at 16:11

You can use almost any object opacity for that, for example:

Panel1->Opacity=0.5;

The question states that Opacity is for animations, and that it doesn't work – matsjoyce Oct 06 '14 at 16:32
