i tried to add custom items to tf container but they are not shown ?
Does TF control its CM and forbid its CM to be modified ?

Any ideas ?

i did not try the suggested one yet since it will need user at least to invoke the CM at least once. My current approach is to add a sprite to current textline when selection happens then add a CM to that sprite. it works well .

What I did was extend containerController to allow me to pass in the contextmenu for the textflow here is that simple class:

package classes.Email
{
    import flash.display.Sprite;
   
    import flashx.textLayout.container.ContainerController;
    import flash.ui.ContextMenu;
   
    public class CustomController extends ContainerController
    {
        public var cm:ContextMenu;
        public function CustomController(container:Sprite, con:ContextMenu, compositionWidth:Number=100, compositionHeight:Number=100)
        {
            cm = con;
            super(container, compositionWidth, compositionHeight);
        }
        protected override function createContextMenu():ContextMenu{
            cm.clipboardMenu = true;
            return cm;
        }
    }
}

This seems to work perfect!

container itself does not dispatch ContextMenuEvent. So your point seems not valid.

You're right, I'm sorry about that. What I meant was you add the event listener to the context menu for the container (container.contextMenu property). You may have to create a new ContextMenu and assign it to the container if it doesn't have one, but I think that TLF does this when you create a DisplayObjectContainerController for a container.

Alternatively, if you are in a position to be able to extend DisplayObjectContainerController for use with your container, you can do that and then override the protected method 'processContextMenuSelectHandler', which will be called automatically whenever a user 'right' clicks in the container. You can override in your class, make sure you call super, and then add items to the customItems array on the context menu. This is probably the cleanest way to do it if you can. But you should be able to handle outside the context of the container controller if you wish. If you do it outside of the container controller, keep in mind that (I'm fairly certain) the TLF container controller will also be handling the same event that you are, and you might need to adjust the priority of the listener depending on what exactly you're trying to do.

Hope this helps.

Best way to add context menu items is to add an event listener to the container for ContextMenuEvent.MENU_SELECT (i think that's the right one). In the event handler, you can access the context menu via event.target as ContextMenu and then manipulate custom items, which will actually be in the context menu by the time the user sees it. Also, by handling this way you can control which items are displayed/enabled based on the current selection, etc. BTW, if you add custom items and add listeners to those, you'll probably want to make sure that you use weak listeners for the menu items.
