[Qgis-developer] How to pass xMax, xMin, yMax, yMin of a current zoomed view

[Echavarria Gregory, Maria Angelica]

HI EVERYBODY,

Im creating a Qgis application. I need to pass to my code the map coordinates of my current zoomed-in view (need the actual corners in GWS to set the bounds of an image that will be further created in my code and then will be superimposed to this exact map area). I found QgsRect.xMax(), xMin(), yMax() and yMin()... and QgsRect.extent(). Is QgsRect the correct class? how should I use these functions if correct for my purpose? should I write them inside my zoomIn tool method after self.canvas.setMapTool(self.toolZoomIn)? none of my trials has worked... please I need guidance.

Thanks a lot
Angelica.
