<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Trying to get a map canvas event when canvas is clicked and mouse is dragged. I have code that creates an empty layer, but I use the QGIS edit menu to add the actually layer. I want to be able to track the mouse movement so I can calculated
the area of the feature being drawn in real time so I can make sure the area is within a defined range.

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there an event I can connect to so I can run my custom code when the even occurs?<o:p></o:p></p>
