I am having problems with the zoom in QGIS 1.8.0 where a slight move of the scroll wheel on the mouse zooms way way out. It will re-render at each zoom level and with large datasets it takes over the computer for sometimes up to a minute. Is there a way to disable the mouse wheel zoom in QGIS?

I hope somebody can answer this. It's even worse on laptops with scrolling trackpads.– L_HolcombeOct 19, 2012 at 19:34

In the preferences under 'Panning and Zooming' there is a dropdown labeled 'Mouse Wheel Action'
Set this to 'Nothing' and all will be well.

You might also want to look at the options on the identify function as changing them from the default 'selected' is more like Arcmap Nov 3, 2012 at 10:25

2Also found that setting Mouse Wheel Action as 'Zoom to mouse cursor' and setting Zoom factor to 1.1 is a reasonable work-a-round. Then a light tap on the magic mouse if zooming in too fast will stop the zoom in its tracks.– DionMar 16, 2014 at 8:12

1Any ideas how to do this in QGIS3? The option seems to have been removed.– amballFeb 6, 2021 at 18:59
