Hi Nathan,
Thanks for your reply.
I am a little bit confused as I do not really know how to set the mouse
position. I have a solution, but it is not giving the same experience as
when you create a new feature in a layer:
I use the canvasMoveEvent, I get the point in pixels in the canvas using
result,snappingResults =
QgsMapCanvasSnapper(self.canvas).snapToBackgroundLayers(pixPoint,[])
The best I could do is calculating the difference in pixels:
self.transform = self.canvas.getCoordinateTransform()
snappedPoint = QgsPoint(snappingResults[0].snappedVertex)
startPoint = self.transform.toMapCoordinates(pixPoint.x(),pixPoint.y())
dx =
(snappedPoint.x()-startPoint.x())/self.transform.mapUnitsPerPixel()
dy =
(snappedPoint.y()-startPoint.y())/self.transform.mapUnitsPerPixel()
And then setting the cursor by applying this difference:
qcur = QCursor.pos()
QCursor().setPos(qcur.x()+dx,qcur.y()-dy)
I am quite sure there is a smarter way, but I cannot find it!
Also the problem is that the mouse is oscillating using this method. The
only reason I can give is that canvasMoveEvent is sent again before the
previously called method has returning, could it be true?
I am a little bit lost in this. I would really appreciate your help!
Thanks again,
Denis

Hey Denis,
The QCursor setPos
<http://developer.qt.nokia.com/doc/qt-4.8/qcursor.html#setPos>methods
are static so you shouldn't need to get access to the instance to move
the cursor position.

Is there anyway to access the QCursor within QgsMapToolEmitPoint.
I see there is a mCursor, but it's protected.
