In a GtkTreeView I use append_column to add the columns and use GtkTreeStore as model, as shown in your examples.

The first column in the TreeView contains the registration number of a vehicle, the following columns contain the ID of drivers/customers that have booked the vehicle. There could be 1 to n drivers. Clicking on the cell of the driver, should reveal the details of the driver.

The following maps the changed event to my processing function.
$selection = TreeView->get_selection();
$selection->connect('changed',array($this, 'cbkCellSelect'));

In cbkCellSelect list($this->model, $iter) = $selection->get_selected();

$iter gives me access to all the row's data, but I don't not know which cell got clicked.

What methods/signals/means are available to find out which cell got clicked?

Hi Peter,

Please refer to the following sample code:

How to display context-sensitive popup menu with right mouse click in GtkTreeview?

Basically you make use of the signal "button-press-event" to get the mouse-click position, and then use the method GtkTreeView::get_path_at_pos() to transform the mouse position into row and column position.

The example uses right mouse button. You can easily adapt the code to use it for left mouse or middle mouse clicks.
