Everything works through the dataProvider. First use e4x expressions to
find the node you want to change, then set the attribute. Below are
some lines from some of my code. I am only setting enabled and the
label, but the same techniques should work for checkboxes, etc.

public function set xmlSelectedItem(xml:XML):void
{
_xmlSelectedItem = xml;
var sNodeName:String;
var sActionType:String;
var sAction:String;
var sTemp:String = "";
var sLabel:String = "";
var xmlCopiedItem:XML;
if (_xmlSelectedItem) {
sNodeName = _xmlSelectedItem.name();
sActionType = [EMAIL PROTECTED];
sAction = [EMAIL PROTECTED];
xmlMenu..menuitem.(attribute("action") ==
'deleteSelected')[EMAIL PROTECTED] = true;
xmlMenu..menuitem.(attribute("action") ==
'copySelected')[EMAIL PROTECTED] = true;
xmlMenu..menuitem.(attribute("action") ==
'addMenuItem')[EMAIL PROTECTED] = true;
xmlMenu..menuitem.(attribute("action") ==
'addAppItem')[EMAIL PROTECTED] = true;
if (sNodeName == "menu") {
sTemp = " to '" + [EMAIL PROTECTED] + "'"
}
else {
sTemp = " to '" + [EMAIL PROTECTED] + "'";
}
sLabel = "Add Menu Item" + sTemp;
xmlMenu..menuitem.(attribute("action") == 'addMenuItem')[EMAIL
PROTECTED]
= sLabel;
sLabel = "Add Application Item" + sTemp;
xmlMenu..menuitem.(attribute("action") == 'addAppItem')[EMAIL
PROTECTED] =
sLabel;

Subject: [flexcoders] Controlling MenuBar Submenus via Code frustrations
Greetings All,
I've burned an entire DAY searching the web for examples of how to
control sub-menus in a MenuBar control, via code. The main types of
things I need to accomplish, is toggling Checkboxes and Radio Buttons,
when certain application variables change.
My MenuBar has 6 primary menus across the top, and each primary menu,
could have any number of additional sub-menus (which have several
variations of menu types - Checkboxes, Radio Buttons, etc.)
My MenuBar is being populated via an external XML File.
Per the docs, each top level menu is considered a 'MenuBarItem', but
there is very little helpful information after that. All the help docs
focus primarily on listening for MenuBar events and writing functions to
respond - but there is NOTHING on how to do the reverse.
I consider myself to be a fairly seasoned Flex Programmer, but this
MenuBar stuff has got me stumped, and quite frustrated.
If anybody has any examples on this topic, I would be VERY grateful.
Thanks in advance for any help,
Mike
