 Posted: Mon May 22, 2006 10:04 am Post subject: connecting clicked to a GtkTreeViewColumn |
 |
|
Hi!
I am stuck again....
| Code: | $cell_renderer = new GtkCellRendererPixbuf();
$colString = new GtkTreeViewColumn();
$treeview->append_column($colString);
$colString->pack_start($cell_renderer, true);
$colString->set_attributes($cell_renderer, 'pixbuf', $storepos);
$colString->connect("clicked", array($this,"delete_klicked"), $this->store, $storepos );
|
I have done this because the GtkCellRendererPixBuf doesnt emit signals.
But it seems that the Column doesnt emit that signal too. -- the doku says yes...
Whats wrong with my coding?
Have a nice week

GtkCellRenderer themselves can't emit signals as they aren't widgets. All a cell renderer gets is some coordinates (a rect) and the value that shall be drawn into the rect. Further, the cell renderer is used several times for each row - a widget could be used only at one place.
The column is a GtkObject, but no GtkWidget. You need to catch the mouse-press or mouse-release-events on the list and use the coordinate transformation methods to find out which row and which column has been clicked. |

Hi!
Okay I have changed my coding:
| Code: | $treeview=$this->get_widget('treeview1');
$treeview->set_model($this->store);
$treeview->set_events(MY_MASK);
$treeview->connect("button-press-event", array($this,"ButtonPressCallback"));
|
I can see the events in my function:
| Code: | function ButtonPressCallback($widget, $event)
{
$window = $event->window;
$pointer = $window->get_pointer();
new Gtk2_VarDump($window, '');
}
|
But now I am stuck again. I only get the inner coordinates of my treeview. When I scroll down my ListStore I do get the same values in the Event... And the ListStore has no method set_events ...
What do I have to do now? How do I get the binding between my ListStore and the event? May be some one can give me a hint?
Thanks in advance

| GtkTreeView::get_path_at_pos(x, y); |

Thanks a lot.
Now I can click on a pixbuf in a treeview to remove the line from a liststore.
If someone is interested I put the codesnippets online.
Have a nice week and "Vatertag"

Oh no, it's
"Christi Himmelfahrt", not "Vatertag", because the last one is a bad excuse for many men to drink too much on that day.
And with luck, there are many of these men in the rain, i ride(?) tomorrow to Vienna .....
Greetings
