Disabling list item?

[DelvarWorld]

This is driving me crazy, it seems like it should be simple but I haven't been able to find any documentation on it anywhere. I have a List() that I've created and populated with a DataProvider. I want it so that when you click on a list item that item becomes disabled (in the same way you set list.enabled = false).

Since I haven't found out how to disable the list, I have something like this which just removes the entry:

list.addEventListener(Event.CHANGE, stuff);

function stuff(event:Event) {
    list.removeItem(event.target.selectedItem);
}

I've tried event.target.enabled = false and event.target.selectedItem.enabled = false and neither are working, and I can't find jack diddly anywhere about how to disable individual list items so that you can't click on them.

Yes - I've also been searching around for what seems a rather essential thing - being able to disable a row/item in a list component. Have found an AS2 answer that may or may not work - but, like you, I'm looking for something in AS3.

Where I've got to:

I've created a new class that extends the CellRenderer class (and so implements ICellRenderer).

I've overridden the set listData method. In the new method, I check for the presence or lack of a data element (enabled, say) and can then set the style of that row accordingly.

What I can't work out how to do is stop that row from responding to rollover and mouseUp/Down events. Presumably I need to removeEventHandler from that row - but what is the event handler called for the CellRenderer class?

Anyone got any thoughts on how to achieve this - either by completing this method above or via some other route?

What would obviously help is some sort of more complete documentation on dealing with the components - but haven't seen anything beyond the adobe livedocs which are very far from complete as far as I can tell.

Thanks,

Alex

After some more experimenting - here's the solution, I think. Might help some googlers ...

First create a new cellRenderer file - I've called the cell renderer mc_sw_cell, so it goes in the file mc_sw_cell.as.

Then enter the following code. This disables the row where it has a property of v_enabled == "false". It also grays out the row text - substitute your own text format if you want something different.

package {

import fl.controls.listClasses.CellRenderer;
import flash.text.TextFormat;

class mc_sw_cell extends CellRenderer {

private var tf:TextFormat = new TextFormat();

public function mc_sw_cell() {

}

override public function set data(newData:Object):void {
_data = newData;

tf.font = "ITC Officina Sans Book";
tf.size = 16;
tf.bold = false;
tf.color = 0x777777;
tf.leading = -4;
tf.align = "center";

var originalStyles:Object = CellRenderer.getStyleDefinition();

setStyle("upSkin", originalStyles.upSkin);
setStyle("downSkin",originalStyles.downSkin);
setStyle("overSkin",originalStyles.overSkin);
setStyle("selectedUpSkin",originalStyles.selectedU pSkin);
setStyle("selectedDownSkin",originalStyles.selecte dDownSkin);
setStyle("selectedOverSkin",originalStyles.selecte dOverSkin);

if (_data.v_enabled == "false") {
setStyle("textFormat", tf);
mouseEnabled = false;
}

}

}

}

Finally, set your list view's (here called aList) cellRenderer to your new one:

aList.setStyle('cellRenderer', mc_sw_cell);

And, for instance, add disabled rows with:

aList.addItem({label:v_label, data:v_id, v_enabled: "false"});

does anyone know how to stop the whole list from going grey when

list.enabled = false;
