Treeview row click to open the entry text

["Arthur Maciel" <arthurmaciel gmail com>]

Hi there.
I have a treeview that contain editable cells with text entries on its second column (the first column contains just a label). When I want to write on the text entry, I have to click one time (to select the row) and a second time (to "open" the text entry). Is there a way to move the focus and enter the "edit mode" on the text enty when just clicking one time at the treeview row? 

Don´t believe I was clear. Please let me know if you could not understand.

Regards,
Arthur
