I don't know how to do it ... I red many tuts but I don't understand how to
implement this.
As the program starts the event "cursor-changed" occurs, so I implemented this
event in my sub
sub theme_center_options_treeview()
{
:
# create a treeview, specify $tree_store as its model
my $tree_view = Gtk2::TreeView->new($tree_store);
$object{'theme_center_options_treeview'} = $tree_view;
$tree_view->signal_connect("cursor-changed" =>
\&on_theme_center_options_treeview_cursor_changed);
# create a Gtk2::TreeViewColumn to add to $tree_view
:
}
In the callback sub I check if the event occurs at start time or later when a
row will be clicked:
sub on_theme_center_options_treeview_cursor_changed()
{
my $treeview_object = $object{'theme_center_options_treeview'};
my $selected_row;
if ($start_init == FALSE)
{
my $treeselection = $treeview_object->get_selection();
$selected_row = get_treeview_row(\$treeselection);
}
else
{
my $treeselection = &set_treeview_row($treeview_object, "Theme Manager");
$start_init = FALSE;
}
}
By checking the Gtk2::tree*** modules I found in Gtk2::TreeModel
$tree_model->row_changed ($path, $iter)
so I tried
$treeselection->select_iter($treeiter);
$tree_model->row_changed ($treepath, $treeiter);
but it doesn't help :-(
