hi all,
thanks in advance for your valuable reply.
I have a pygtk code. which is a simple tree view. and when i click on
any row of the tree view, i get a menu poped up. and i can click on
the options in the poped up menu. and it goes to a function. up to
this its fine with me. but now from this function, how do i get the
name of the tree row which i clicked. ?? I tried some get_path &
get_iter method and tried to pass it with the call. but i could not
get it. I pasted the test code which used. please correct me if i am
doin any mistake, though i am new to this language.
the code is pasted below.
in the function print_A(), i tried some things. ultimately i wanted to
get the name of the row in tree from this function. (ie: like 'CHILD 1
1' or 'PARENT 2' )
any comments on these will be helpful to me. because i am very new to
pygtk
