Hello,

What signal is emitted when a user clicks on a row? I've tried a few
like row_activated but it emits a signal only when "return" is
pressed.
If you mean "double click on a row", try 'row-activated'. If you really
want to catch basic mouse clicks, try 'button-pressed-event'. You can
then determine the position from the event:
x = int(event.x)
y = int(event.y)
Of course you usually want to know where you clicked, so you use
something along the lines given here:
try:
path, col, cellx, celly = widget.get_path_at_pos(x, y)
except TypeError:
# blank region selected (no row)
pass
else:
# example what to do if user clicked on a valid cell:
# If user clicked on a row, then select it.
selection = widget.get_selection()
if selection.count_selected_rows() == 0:
widget.grab_focus()
widget.set_cursor( path, col, 0)
I think this code snippet has been taken from an example on popup menus
in the FAQ.
Another problem is I'm using a button called "Expand" to expand
everything using treeview.expand_all() but it shows the expanded tree
only if I use alt+tab back and forth terminal and GUI - it appears
there is some refresh problem. Any ideas?
I remember me asking a similar question and I think this problem was
solved in some gtk release. What gtk+ version are you using? If you
don't want to update your gtk+, you can issue a redraw. I am not 100%
sure, but I think you use widget.queue_draw() for this.
Niklas.
