[Flashcoders] Disable Row in ListBox Component

2006-09-20 Thread azsl1326-email
Hello All ---

Is it possible to disable a row or number of (specific) rows in a ListBox 
without disabling the entire ListBox?

Thanks for any and all replies.

i think you have to do this manually.
you either create a cellrenderer for your list and handle it this way (look in the help for 
cellRenderer API) or you could :


var list:mx.controls.List;

list.addItem({label:Flash, data:{value:1, enabled:true}} );
/**/
list.addItem({label:Dreamweaver, data:{value:2, enabled:false}} );
list.addItem({label:ColdFusion, data:{value:3, enabled:true}} );


function onListClick (evt:Object)
{
var list = evt.target;
//
if (!list.selectedItem.data.enabled)
{
list.selectedIndex = undefined;
list.invalidate();
trace (this item is disabled)
}
else
{
trace (you selected:  + list.selectedItem.label)
}
}
function onListRollOver(evt:Object)
{
var list = evt.target;
var ix = evt.index;
var item = list.getItemAt(ix);
	var curCol = list.getStyle(backgroundColor); // be aware of alternatingRowColors, you'd 
have to check here if ix is odd or even, also you should check that there's no cutom 
cellrenderer here

//
if (!item.data.enabled)
{
list.setPropertiesAt(ix, {backgroundDisabledColor:curCol});
list.invalidate();
}
else
{
trace (you hovered:  + list.selectedItem.label);
}
}
list.addEventListener ('change', onListClick)
list.addEventListener ('itemRollOver', onListRollOver)


cheers
