Re: [pygtk] How do I get the row count from a CList/CTree?

You really shouldn't set private data manually like this.  The
jump signal is much better.

I think this C function does the trick but I haven't found a way to do it
in python :-(.

void 
   gtk_clist_set_focus_row(GtkCList *list, guint row) 
   { 
   g_return_if_fail(list != NULL); 
   g_return_if_fail(row >= 0); 
   g_return_if_fail(row < list->rows); 

   list->focus_row = row; 
   } 

Hope this helps, I you find a good way to focus row in CList I would be
happy to hear about it!!!

For a clist I just keep track of the last row I appended:

for row in rows:
last = clist.append(row)


Also, if you don't know how may rows you have you can wrap row access in a
try/except block:

i = 0
while 1:
try:
text = clist.get_text(i, col)
# do something with text
i = i + 1
except:
break

I would like to have an accessor method for this, though.

You would use the GtkCTree.node_moveto function.  You probably want
something like:
  ctree.node_moveto(node, 0, 0.5, 0.0)

The second argument is a column number, the third is the vertical row
alignment, and the last is the column alignment (I used 0.0 to put the 0th
column at the left of the display).

I don't know about any way to get this info in pygtk. The CList has an 
instance variable rows which could be wrapped by pygtk.

Another question about CLists: is there a good way to set the focus
row to a given position, even on C level? The only way I have found is
to emit a scroll_vertical signal with SCROLL_JUMP, which expects a
relative value (0..1) for the postion; you need the number rows to
calculate this value.
