示例1: node_drag_motion
# 需要导入模块: import base [as 别名]
# 或者: from base import transform_distance_canvas_to_simulation [as 别名]
def node_drag_motion(self, item, targe_item, event, node):
self.simulation.lock.acquire()
try:
ns3_node = ns.network.NodeList.GetNode(node.node_index)
mob = ns3_node.GetObject(ns.mobility.MobilityModel.GetTypeId())
if mob is None:
return False
if self.node_drag_state is None:
return False
x, y, dummy = self.canvas.window.get_pointer()
canvas_x, canvas_y = self.canvas.convert_from_pixels(x, y)
dx = (canvas_x - self.node_drag_state.canvas_x0)
dy = (canvas_y - self.node_drag_state.canvas_y0)
pos = mob.GetPosition()
pos.x = self.node_drag_state.sim_x0 + transform_distance_canvas_to_simulation(dx)
pos.y = self.node_drag_state.sim_y0 + transform_distance_canvas_to_simulation(dy)
#print "SetPosition(%G, %G)" % (pos.x, pos.y)

finally:

return True
