LMD SyntaxEdit: How to get physical line in the OnGutterPaint event?

Christer Bergström

I have an event handler for the OnGutterPaintEvent.

The TLMDGutterPaintParams record has a field ScreenLine. 

My task is to convert this ScreenLine to a physical line for my document in the editor. 

Then I check if it is a modified line, and if so does some custom color painting in the gutter area (yellow for a modified line, and lime for a modified and saved line).

There is a ScreenToPhysical function but it is inside TScreenCache.

The edit view holds a field FScreenCache but it is private.

So I cannot directly access it from my edit view, if I understand it correctly (without changing your source code at least).

Have you got any suggestions?

I'm using Delphi 12 (update 1).

Thanks for any help!

Best regards

Christer

Hi, you can do it like this:

  ScrollLine := ScreenLine + MyEditView.TopLineScroll;

  PhysLine  := MyEditView.ScrollToPhysical(ScrollLine);
