Re: [Qgis-user] Trapping Kyb/Mouse events during a QGIS geometry edit process

2022-05-07 Thread Richard Duivenvoorde via Qgis-user 

I'd start to look into the advanced digitizing tools code, or in some (older?) 
cad-like plugins (QAD is a pretty extensive one)? They often also show 
position/angle/whatever info?

The 'thing' you see during digitizing, is (I think) a QgsGeometryRubberBand

https://qgis.org/pyqgis/3.22/gui/QgsGeometryRubberBand.html#module-QgsGeometryRubberBand

That one has a lot of events

HTH,

Richard

Hi Listers,

I'm looking to trap kyb/mouse events whilst in the middle of a geometry edit.
If a suitable event is trapped, then to run a subroutine and then return to the 
edit process by either handing the edit process the same event or generating 
another event for the edit routine to continue the geometry edit with.

So I suppose my question is, is where do I insert such kyb/mse event filter.

Any pointers would be welcome.

Thanks in advance,
Zoltan
