Re: [qooxdoo-devel] How to Get The Selected Item Of A QxTree or ListView to use it after..

[Jim Hunter]

This information is nice but it still doesn't tell us what we can DO with getSelectedItems(). In one of the demo's I think I saw that you can do a getSelectedItems().getData(), but no information on what you can DO with the returned data. I would love to see some code snippet showing how to access the second fields data of the second row selected assuming that 3 rows were selected. A simple alert would do. All of my ListViews are dynamically created at run time and I have no idea at design time what fields are going to be in a ListView so I need to be able to access the information generically. I tried to do something like getSelectedItems().getData()[0], trying to reference the first row selected but got a _javascript_ error. There really is no information in the demos that tell you how to manipulate the raw data. The examples that move data from one grid to another never drill down into the data, the leave it as a whole entity. So far I have read as many posts as I can and looked at the demos but I see no information that is relevant to what I need to do. Someone out there has had to have done this before and can show others how it's done.

Thanks,
Jim

The QxTree class has a "built-in" selection manager. You don't have to
set/create an extra instance.

Simply call

treeSource.getManager().getSelectedItems()

to get the selected items of the tree.
For the QxListView class you can call

var listview = new QxListView(dataArray, headerData);
listview.getPane().getManager().getSelectedItems();

to get the selected items of the listview.

Take a look at the examples on the qooxdoo site for even more
information on how this works
