Hello,
I am learning the pygtk tutorial and try to drag and copy a complete row
from one treeview to a empty second, with a gtk.ListStore(int,str,str).
and
finally it works
but
I don't understand why ;-(
I have a few questions.
- in exemple treeviewdnd.py, the row contains only a single string and
the description of targets is:
TARGETS = [
('MY_TREE_MODEL_ROW', gtk.TARGET_SAME_WIDGET, 0),
('text/plain', 0, 1),
('TEXT', 0, 2),
('STRING', 0, 3),
]
Targets is a (or a list of) 3-tuple, OK, but why four tuples in this
list for only one string in the model ?
And first string in each tuple represent the drag type, is the "drag
type" whatever I want to write ? as ('submarine', 0, 0) ?
(with a little more relation with the content, of course)
2nd problem, i have to transform the data of my row (contains integer)
on a single string in the callback drag_data_get_data
and retransform piece of string in integer in drag_data_received_data.
Is it the good way to do ?
I see that in SelectionData.set(type, format, data), data is only a
string, perhaps my english don't help me to understand really
and 3rd, when I add a gtk.gdk.Pixbuf to the models, I did not make the
drag'drop because i dont know how transform an image in string. Here is
why, i think i have not understand very well this section of tutorial
If someone can explain more to me, thanks very much,
and if someone can explain to me in french, if my problem is bad
translation of tutorial and pygtk reference, thanks very, very, very much.
