I have created one python addin tool which creates some points along a line, it works good. my problem is when my tool gets activated i am not able able to zoom/pan the map. map view just get stuck wherever it was before clicking on that tool. more elaborately when i am in the middle of creating a line map view get stuck. using below code: class PointAddressCreateClass(object😞
"""Implementation for PointAddressCreate_addin.tool (Tool)"""
def __init__(self😞
self.enabled = True
self.shape = "Line" # Can set to "Line", "Circle" or "Rectangle" for interactive shape drawing and to activate the onLine/Polygon/Circle event sinks.
def onMouseDown(self, x, y, button, shift😞
pass
def onMouseDownMap(self, x, y, button, shift😞
pass
def onMouseUp(self, x, y, button, shift😞
pass
def onMouseUpMap(self, x, y, button, shift😞
pass
def onMouseMove(self, x, y, button, shift😞
pass
def onMouseMoveMap(self, x, y, button, shift😞
pass
def onDblClick(self😞
pass
def onKeyDown(self, keycode, shift😞
pass
def onKeyUp(self, keycode, shift😞
pass
def deactivate(self😞
pass
def onCircle(self, circle_geometry😞
pass
def onLine(self, line_geometry😞
***Some Code HERE****
its main functionality lies in "def onLine(self, line_geometry)" function. so when i click on the map and start to create a line on map, i want zoom/pan functionality at that time. i guess there should be a function to zoom/pan in active view by either mouse scrolling or may be any other method |
