TELSideBar not rendering correctly in high DPI

Aptean

Hi,

I'm trying to upgrade our application that uses the TELSideBar component as a program navigation mechanism and I'm seeing that it doesn't render correctly on a High DPI monitor situation.

Component: TElSideBar

Package:  LMD ElPack 2024.2 (10-02-2024)

IDE:  (Delphi/C++Builder 12)

I have switched over to using a TVirtualImageList for the item images and here are the results I am getting:

100% screen scaling (expected rendering):


175% Screen scaling (with rendering issues):

At this point we are using ThemeMode=ttmNone if that makes any difference (doesn't seem to if I change that).

Any help or suggestions would be appreciated.

Thanks,

John Beyer

Sorry..didn't realize inline images wouldn't come through.  Images attached.

Hi Eugene,

I've implemented your fixes (from Git) and just have one more minor request...

I think you should also scale SectionHeight in the ChangeScale procedure.

...

  Spacing := MulDiv(Spacing, M, D);

  TopSpacing := MulDiv(TopSpacing, M, D);

  SectionHeight := MulDiv(SectionHeight, M, D);

end;

Thanks,

John Beyer

You're right. Done.
