GTK+ Forums

good morning to everybody

i already asked about another argument in this forum (and Paul Childs is helping me) but i have also another problem

in gtk2 i use gtktreeview (with gtkliststore as object) with multiple selection. i implemented "changed" signal to find which rows are selected. when i use a simple 'click' on list i can find the right numbers of rows selected (1)

but if i use also shift and control keys to select more rows i find a wrong number of selections. to find how many rows i selected i use "gtk_tree_selection_count_selected_rows" and "gtk_tree_selection_get_selected_rows" and what happens is the following:

at 1st simple selection i find 1 row selected (ok)
changing selection (simple selection) i find 1 row selected (ok)
using shift key and selecting (for example) 5 rows i obtain 1 row selected (ko)
then i use ctrl key to remove 1 selection and i obtain 5 rows selected (ko, as previous state)
using ctrl again so select a new line i obtain 4 row selected (ko, as previous state)

in conclusion, using shift or ctrl key modificators, rows counting functions are "late" en respect the real situation

did you verify a similar behaviour? is it a problem solved with gtk3?

thanks in advance

p.s.
xmas is next to us, so i wish you a merry xmas

no one realizes the same thing?

It would be a great help (probably not only for me) if you could provide a minimal working example which illustrates your observation.

In order to get help as fast as possible the example should be readily compilable for everyone who's trying to help you.

At least i would be happy to tell you whether i observe the same behavior you've described. If so i could test if gtk3 lead to the same situation, as well.

I'm looking forward to your code...

Hello,
i have the same problem!
I use vala 0.18 and gtk 2.22 on OpenSuse 11.3 and made the gui with glade 3.8.2
when i set selection to multiple the treeselection (count_selected_rows and get_selected_rows) is always one click behind the treeview.

if i set set_rubber_banding to true and use the ugly gray retangle to select entrys treeview and treeselection are synchronous.

When i have time i make a example for illustration.

I have found a solution:

don't connect to treeview curser_changed
connect to treeview_get_selection changed

goodmorning to everybody

@saunderson
