Hi,
For a few days now QgsMapMouseEvent:: snapSegment is no longer usable
(moved). I need these tools to create circles with tangents
(https://github.com/qgis/QGIS/pull/4947).
Is there another way to get segments by snapping?
Yes - here's the code you need to snap to segments - equivalent to a
snapSegment() call:
struct EdgesOnlyFilter : public QgsPointLocator::MatchFilter
{
bool acceptMatch( const QgsPointLocator::Match &m ) override {
return m.hasEdge(); }
};
EdgesOnlyFilter filter;
match = mapCanvas->snappingUtils()->snapToMap( mapPoint, &filter );
Regards
Martin
