Visual Studio Package: Is it possible to show tooltips on text line markers?
Implementing "squiggle" text line markers in JSLint.NET was quite straight forward as can be seen here:
However, despite implementing IVsTextMarkerClient with the GetTipText method, tooltips are never shown. The GetTipText method is never even invoked when the mouse hovers over the marker.
If I switch to a glyph type (for example MARKERTYPE.MARKER_SHORTCUT), tooltips show just fine in the margin:
Is there some trick to getting tooltips to show on the body of an inline text marker?
Implementation source code is available here in the SetMarker method:
It turns out that the answer (to "is it possible?") is no when using the old IVsTextMarkerClient and IVsTextLines implementations.
It can be achieved by implementing the newer ITag / ITagger / ITaggerProvider interfaces instead. My current prototype looks like this:
