<p class="MsoNormal">When you digitize a shape using the Edit
menu in QGIS is the shape accessible? I am looking to get he
area of the shape as it is drawn. I have added an event
filter to my code to capture the coordinates and calculate it
by creating a QgsGeometry, but my code is getting complicated
as there are many shapes that a user can draw from this menu
so if I can get access to this shape if it is temporary in
memory, then I can just calculate the area on the shape and
not have to capture all the positions of the mouse when
clicked and moved.<o:p></o:p></p>
