Delphi 2009 - create a TPanel at runtime and change its color

Question

got a strange problem: I create a TPanele at runtime and change its color - however, the color is still clBtnFace.

Here' the code:

procedure TForm1.Button1Click(Sender: TObject);
var
  pnlTest : TPanel;
begin
    pnlTest := TPanel.Create(Form1);
    pnlTest.Parent := Form1;
    pnlTest.Width := 100;
    pnlTest.Height := 100;
    pnlTest.Color := clRed;
end; 

Any ideas? Thanks!

Answer 1

When you want to have colored panels under a themed OS you have to set ParentBackground to False.

Try this :-)

procedure TForm1.Button1Click(Sender: TObject);
var
  pnlTest : TPanel;
begin
    pnlTest := TPanel.Create(Form1);
    pnlTest.Parent := Form1;
    pnlTest.Width := 100;
    pnlTest.Height := 100;
    pnlTest.ParentBackground := false;
    pnlTest.Color := clRed;
end;
