python - How source object can receive feedback information of object at dropping moment (DataSource)? -

-

i have 1 window - editwindow ( object of class, inherit wx.frame ), contain grid object (self.grid). in class write method:

def onsubindexgridcellleftclick( self, event ):         ....         dragsource = mydropsource( self.grid )         dragsource.setdata( data )         dragsource.dodragdrop()         event.skip()

and bind in __init__ of editwindow :

self.grid.bind( wx.grid.evt_grid_cell_left_click, self.onsubindexgridcellleftclick )

in window - "variablewindow" have got grid - "variablesgrid" , determine following class:

class variabledroptarget(wx.textdroptarget):     def __init__(self, parent):         wx.textdroptarget.__init__(self)         self.parentwindow = parent      def ondroptext(self, x, y, data):         x, y = self.parentwindow.variablesgrid.calcunscrolledposition(x, y)         ....

in window set drop target:

self.variablesgrid.setdroptarget(variabledroptarget(self))

how can hook information of object - "variablesgrid" @ moment, when drop cursor grid (which situated in editorwindow). want take information of data in variablesgrid , how editwindow can receive information ? sorry bad english.

you use pubsub send data editorwindow , display it. sending in ondroptext method only sends when drop @ end of drag. here's simple tutorial on pubsub going: http://www.blog.pythonlibrary.org/2010/06/27/wxpython-and-pubsub-a-simple-tutorial/
