Just testing out the plugin, when it is enabled in plugin manager I get this:

An error has occured while executing Python code:

Here I don't get this error (under Windows 7)... Maybe it's a mac-only problem ?

I'm not really sure on how to workaround this problem without modifying the core (having public methods for mouseMoveEvents). Anyone on this ?

Confirmed the same error on Linux (LinuxMint Debian Edition) QGIS master qgis/QGIS@d0d5581

I'm not able to reproduce here under Ubuntu 12.04 in QGIS dev... That's strange !

A possible workaround may be using QtCore.QCoreApplication.postEvent(self, mouseMoveEvent ).

Does the problem occur all the time and prevent using the plugin, or does it still work afterwards ?

Yes it basically makes QGIS unusable as every time you move the mouse the message appears.

@timlinux @mach0

Ok I found a better way to do this... Before I change too many things, can you please test the branch testWithEventFilter ?

If it works, you should see red dots appearing at random in front of the mapCanvas, all mouse inputs will be shaky (but except that work as normal) and more importantly no Runtime error...

Thanks !!

Hi

That resolves the exception but I am getting an orange circle flashing on the map as I move the cursor around.

Regards

Tim

@timlinux

Ok that was expected, maybe it was a bit too artistic for a simple debug run ;)

@mach0 @timlinux I've rewritten the mouseEvent part, the problem should be solved (along with other small improvements) in master. Can you try it again ?
