Question

I have create a menu but when clicking on menu so that it shows, I get an error on the line because of the line “myMenu.show(null,null)”. See function below:

private function createAndShowmyMenu():void {


                myMenu = Menu.createMenu(null, myMenuDataProvider, false);
                myMenu.labelField="@label"
                myMenu.setStyle("fontSize","10");
                                //Event Listeners Here


                myMenu.show(null,null);


            }

The Error is as such:

TypeError: Error #1007: Instantiation attempted on a non-constructor.

Anyone has an idea with this?

Answer 1

myMenu = Menu.createMenu(SOME_DISPLAYOBJECT_HERE, myMenuDataProvider, false);
myMenu.labelField="@label"
myMenu.setStyle("fontSize","10");
myMenu.show();

You should really try to read the documentation, debug your code or even look at the sdk code before posting a question.
