Thx 4 your quick answer.
But sorry - SpkToolbar1.Appearance.Pane.Style := psRectangleEtched; does not work though.
I tried it the same way - without success. Lazarus gives me unit1.pas(41,40) Error: Identifier not found "psRectangleEtched"
The operating system I use ist openSUSE Leap 15.0 (64Bit). spktoolbarpackage.lpk tells me "<Version Minor="1" Release="6"/>"
SpkToolbar was installed via Online-Package-Manager.
Regards
Mike
