[python-win32] Creating python com objects

[Alex Denham]

class PyIDropTarget:
    _public_methods_ = ['DragEnter', 'DragOver', 'DragLeave', 'Drop']
    _reg_progid_ = "Python.PyIDropTarget"
    _reg_clsid_ = '{00000122-0000-0000-C000-000000000046}'
    def DragEnter(self, args=None):
        print 'DragEnter: ', args
    def DragOver(self, args=None):
        print 'DragOver: ', args
    def DragLeave(self, args=None):
        print 'DragLeave: ', args
    def Drop(self, args=None):
        print 'Drop: ', args

Then i just used the com register thing to register it, then i tried dropTarget = win32com.client.Dispatch("Python.PyIDropTarget")
I didn't know about the pythoncomWrapObject however.
