TLMDEditView Scrollbar Style

Craig Thomson

I have VCL styles enabled in my project, but I have noticed that the TLMDEditView does not paint the scrollbar (it paints native).

Perhaps I am missing a property? I tried applying a style hook like so:

initialization
  TStyleManager.Engine.RegisterStyleHook(TLMDEditView, TScrollingStyleHook);

This does style it correctly, however the behaviour of the scrollbar is affected.

Please advise thanks.

We do not support VCL Styles in Syntax Edit. Only explicit color schemes. However, often using TScrollingStyleHook works fine. Can you describe in more details how scroll bar behavior is affected?

Thanks for reply,

Yes, when using the vertical scrollbar to scroll up and down, whilst still scrolling, if the mouse also moves horizontally it moves the caret across too (almost as if scrolling horizontally too).

EDIT:

The unwanted behavior seems to be when scrolling all the way to the bottom or top of the control.

This is a bug in Delphi's code. It does not happen in XE2, but happens in Delphi 11 or Delphi 12. The control receives MouseMove method call, while, obviously, it should not. So far I see no easy way to overcome it.

Fixed. Will be included in upcoming 2025.1 release.
