fsBold in Style: CheckBox zuweisen

[yankee]

Wieso geht das nicht:

Delphi-Quellcode:

    with TSynCustomHighlighter(FindComponent(StringToHighlighterCpName(ConfForm.HighlighterCombo.Text))).Attribute[confForm.AttriList.ItemIndex] do
    begin
        //Das geht:
        ConfForm.ForePanel.Color :=Foreground;
        ConfForm.backPanel.Color :=Background;
        //Das geht nicht:
        ConfForm.CheckBox2.Checked :=fsBold in Style;
        ConfForm.CheckBox3.Checked :=fsItalic in Style;
        ConfForm.CheckBox4.Checked :=fsUnderline in Style;
        ConfForm.CheckBox5.Checked :=fsStrikeOut in Style;
    end;

an dem with-Teil liegts also nicht...
