 |
|
Hello,
today's question is, how to implement a functionality for TreeStore, that a double click expand the Tree, to show the next level?
Or do I have not seen this in docs?
Greetings

See the PEAR package Gtk2_VarDump. I implemented that for a single-click there. |

Hey Osiris,
I had to find the same thing too.
Here's two bits of code straight out of the working program, but you'll have to rewrite my code to fit your program, but it should put you on the right path.
The true or false on the expand_row function is wether to expand all children too.
| Code: | $this->tree_view->connect ('button_press_event', array ($this, 'tree_view_buttonpress'));
|
| Code: | function tree_view_buttonpress ($widget, $event) {
// Get currently selected items:
list ($model, $iter) = $widget->get_selection ()->get_selected ();
if (!$iter) {
return;
}
$info = $model->get_value ($iter, 0);
if ($event->button == 1 && $event->type == 5) {
// Button == 1 // leftclick
// type == 5 // doubleclick
if ($info['type'] == 'submenu') {
if ($this->tree_view->row_expanded ($model->get_path ($iter)))
$this->tree_view->collapse_row ($model->get_path ($iter));
else
$this->tree_view->expand_row ($model->get_path ($iter), false);
}
else {
echo "not submenu\n";
}
}
}
