I believe this is not possible directly. However, you can connect to button-press-event on the gtk. TreeView .
Then, when event. Type equals to gtk.gdk. _2BUTTON_PRESS convert x and y to tree location using gtk.TreeView.
Get_path_at_pos() . This will return both a tree path indicating the row and gtk. TreeViewColumn object on which the click was made.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
