You can write a subclass of SynEdit, similar (but smaller than) to
TIDESynEditor (in ide SourceSynEditor.pas)
using something like (this displays the procedure top hint)
FTopInfoDisplay: TSourceLazSynTopInfoView;
That is reserving one line of the display for whatever you want it to be.
It is some work though....
Or go the full 9 yards: Implement a top/bottom gutter (and submit it as
patch).
In synedit, you have
FPaintArea: TLazSynSurfaceManager;
FPaintArea := TLazSynSurfaceManager.Create(Self);
FPaintArea.TextArea := FTextArea;
FPaintArea.LeftGutterArea := FLeftGutterArea;
FPaintArea.RightGutterArea := FRightGutterArea;
FPaintArea.DisplayView := FDisplayView;
So that allows to add top/bottom gutter, and reserve the space needed
(set correct boundaries for all other elements.
Note there must be no gaps between them. Gaps will not be painted at all.
