Hi:
I am writing a python plugin to clip images to a user selected
rectangle and am stuck at the point where the plugin gets the
coordinates from mouse clicks. Here are some code snippets from my
plugin:
-
-
-
# connect QGSMapCanvas mouse click event to the rubber band clip
window
# function
self.mapCanvas = self.iface.mapCanvas()
self.emitPoint = QgsMapToolEmitPoint(self.mapCanvas)
self.mapCanvas.setMapTool(self.emitPoint)
QObject.connect(self.emitPoint, SIGNAL("canvasClicked(QgsPoint &,\
Qt.MouseButton)"), self.setClipWindow)
def setClipWindow(self, point, button):
QMessageBox.information(self.iface.mainWindow(),\
"ImageClipperDlg Mouse Click Event"," Here are the
coordinates ")
I have tried many variations of the argument lists but I cannot seem to
get the method/function setClipWindow to be called. Can someone see what
I'm doing wrong?
Thanks,
Bob Bruce
