Hi Jim,
I would suggest to select this initially using a beforeAppear event (of
this file/folder) instead. The problem is that this selection stuff
needs the selection manager of the tree. You must add the child to the
tree first, before you can select it. Alterativly it should also be
possible to remember of this element and select it after all these
for-loops.

I have a QxTree that has about 50 QxTreeFile items in 11 QxTreeFolder
objects. I am initially setting one of the QxTreeFile items to selected
via setSelected(true). This works and when I display the tree that item
is showing as selected. The issue is that when I select another item,
the first one does not un-select. If I click on that item then click on
another it then un-selects. I tried to set the focus of the selected
item to true but that did not help. Is there some little thing I can do
to fix this problem, or is it going to need a code fix?
I was just now running the code listed below and noticed an exception
does come up yet the item still gets selected. Here is the exception:
001531:Failed to execute "_modifySelected()":Modification of property
"selected" failed with exception('_fastUpdate' is null or not an object)
Thanks,
Jim
here is a quick demo to show you what I am talking about:
window.application.main = function()
{
var T = new QxTree("Main");
for (var x=0; x<5;x++)
{
var F = new QxTreeFolder("Folder " + x);
for (var y=0; y<6; y++)
{
var I = new QxTreeFile("File " + x + y);
if ((x == 2) && (y == 3))
I.setSelected(true);
F.add(I);
}
T.add(F);
}
this.add(T);
}
