MACROMEDIA FLEX-FLEX ACTIONSCRIPT LANGUAGE Reference page 734

This property works only with selectable (editable) text fields; it has no effect on nonselectable
text fields.
In Flex, only top-level components in the application can have context menus. For example, if a
DataGrid control is a child of a TabNavigator or VBox container, the DataGrid control cannot
have its own context menu.
Example
The following example assigns the ContextMenu object
ContextMenu object contains a custom menu item labeled "Resize" with an associated callback
handler named
doResize()
this.createTextField("news_txt", this.getNextHighestDepth(), 10, 10, 320,
240);
news_txt.border = true;
news_txt.wordWrap = true;
news_txt.multiline = true;
news_txt.text = "To see the custom context menu item, right click (PC) or
control click (Mac) within the text field.";
var menu_cm:ContextMenu = new ContextMenu();
menu_cm.customItems.push(new ContextMenuItem("Resize", doResize));
function doResize(obj:TextField, item:ContextMenuItem):Void {
// "Resize" code here
trace("you selected: "+item.caption);
}
news_txt.menu = menu_cm;
When you right-click or Control-click within the area of the text field, you see the custom menu
item.
Caution: You cannot use a menu item that is already used by Flash. For example, Print... (with three
dots) is reserved by Flash, so you cannot use this menu item; however, you could use Print.. (two
dots) or any menu item not already used by Flash.
