VCL Styles possible bug with drawing scrollbars

Question

I have a pagecontrol in the center of my main form (form1 in my image), and I want to open other forms docked into the pagecontrol. Because I have many controls on my child form, I need both vertical and horizontal scrollbars (on the child form I have active scrollbars option active), but here is the catch: when I use VCL Styles, my scrollbars aren't drawing as they should be and they are unusable. Is this some kind of a bug of VCL Styles?

Answer 1

The scrollbars (TControlScrollBar) used by the TForm doesn't support the Vcl Styles (you must report this to the QC page), if you want fix that you must override that control and paint the scrollbars using the Vcl styles methods, but that will requiere a lot of work, as simple workround you can use the TScrollBar component (in your form) which properly supports the vcl styles.
