would be nice to have a method on TreeCell able to return the selected cell.

we can easily detect which item are selected, just adding an listener and casting event.item is enough.

after google the web for some time many sources recomend me to use JFace for that, but i think that it's could be better implemented by adding a method on TreeItem.

There is no SWT API called TreeCell. I guess you meant TreeItem?

sorry for mistake. That's it, TreeItem. someting like item.getSelectedColumn() or getSelectedIndex().

it's very useful and don't want my app depending on jface. unless of course i have no choice, ;)

TreeItem == a row in the tree
You can get the selected items using getSelection() and the selection count using getSelectionCount(). SWT does not have the concept of selection a "cell" within the row. Closing as wont fix.

Please reopen the bug if you believe I've misunderstood your request. Thank you.

thanks for the patience.

see, the snippet 111 shows me how to place a dynamic editor on my tree, actually it also have calls to inform which column i want to edit.

by adding the tree observer to watch clicks i can recover the item and if i always edit the very same column it's ok.

i was wondering a way (like jface does, but i still don't want to depend on jface, since would be nice to have it as a core feature) to given that i have the selected TreeItem also have a method do figure which cell/column exactly i clicked.

select the row the toolkit already does and does it pretty well, i have getSelection and event.item to serve me. the problem is just which column/cell on that item the user clicked exactly.

i'm reopening and hope to see that sugar in 3.6, ;)

thanks in advance.

Sorry, but this level of detail is something you'll have to depend on JFace for.
