I would like to make use of Signal and Slot while using PyQgis along with PyQt4.
Despite spending some time trying out tutorials and some somewhat related post on gis.stackexchange I can't figure out a proper way of using the canvasClicked signal returned from the QgsMapToolEmitPoint Class (API doc).
Here after is where I'm at. I am building my application from the few tutorials man can find over the internet.
self.clickPoint_action = QAction( QIcon(":/ourapp/zoomin_icon"), "Click Point", self) # create toolbar self.toolbar.addAction(self.clickPoint_action) # connect the tool self.clickPoint_action.triggered.connect(self.clickPoint) # create the map tool(s) self.tool_clickPoint = QgsMapToolEmitPoint(self.map_canvas) def clickPoint(self): self.map_canvas.setMapTool(self.tool_clickPoint)
So, I understand how to set my map tool (and successfuly use other built-in and custom MapTool), but can't figure out where to go from there to get the corresponding QgsPoint emitted after a mouse click.
I have few experience on Python and just dive into Qt and PyGIS but already have some background mostly wth java.
thanks for sharing!
