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.
You got an error, because it must be getSelectedItems()[0] .... the
getData() method only works on the QxListView instance ... or on your
QxData event that you receive when you listen on the "changeSelected"
event of the listviewpane's selection manager ... depending on how you
get to the data of the selected items ... maybe you want to add the
following snippet to your app and see what happens (may contain syntax
errors, sorry for being too lazy to test it)
listView.getPane().getManager()
.addEventListener("changeSelection",
function(e) {alert(e.getData().length +" "+ e.getData()[0]) }
);
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.
Ok, now because I can't keep my mouth shut ... tell me an exact example
what you want to do (e.g. change one column of data at runtime,
manipulate just the selected rows of a list), so I get an idea what you
are looking for, and I'll try to do a short writeup with an extended
example.
