ColumnTree selected item

[objects]

May be a stupid question but how do I find the selected item in a ColumnTree (Miller Columns)?

What I'd like is to have a form (DynamicForm I think) display the details of whats selected in my ColumnTree.

Missing API in SmartGWT - through JSNI you could call columnTree.getSelection(colNum)

thanks for that. What type of smartclient component is used under the hood by the ColumnTree? I looked in the smartclient explorer and couldn't see anything.

Each column is a ListGrid. If you look through the SmartClient docs for 7.0 beta (a separate download, sorry), there's a little more information, which will make it's way into the SmartGWT docs soon.

thanks for that its all a bit clearer now.

Just been looking at the Pattern Reuse example which is close to what I'm after except using a ColumnTree instead of a ListGrid. Looking at the source for that example it appears I need to be able to add a RecordClickHandler to the ColumnTree's underlying ListGrid(s).

This is looking a bit involved at this point so I might hold off and wait on a later release unless you can point me in the right direction :)

ColumnTree.getSelected(colNum) has been added to build 12-17-2008.

method name changed

ColumnTree.getSelected(colNum) has been added to build 12-17-2008.

now it's called getSelection(colNum).

Note that you need to return ListGridRecord objects in your DataSource, I tried to return Record objects and got a "ClassCastException: cannot convert from Record to ListGridRecord" when called this method, even though they were displayed just fine.

Cheers!

a bit more detailed?

Hi cirovladimir,
thanks for the update.

Can you or anyone else provide a bit more detailed explanation?

i get the ListGridRecord object , use a clickHandler but still not able to find the selected e.g. string i clicked on.


Besides , is there any simple way to get back all the selected items from all the previous columns?
