If you look at again at the Contact Manager app you'll see I added context menus to the View, as below, where you can see an edit and a delete option for each row:

The edit option simply dispatches the View's custom "openDocument" event back to the parent application, which is where we handle opening the document.

For now the delete option is handled by the View object itself. Although it doesn't work yet I added it in as an example of using the Alert object for more than a simple "Ok" message. As you can see below if you choose the delete option you see an "advanced" Alert.

How did I do this?

Until yesterday I'd assumed that the flex Alert did nothing more than show a popup prompt with a message and an Ok button.

I presumed that, to do anything like asking a Yes/No question, it would involve creating custom components based on the TitleWindow. Doh. Turns out that Flex's Alert is akin to LotusScript's Messagebox. Here's the code for the above delete confirmation prompt:

Alert.yesButton="Delete";
Alert.noButton="Cancel";
Alert.show(
  "Are you sure you want to delete this document?", 
  "Delete", 
  Alert.YES|Alert.NO, 
  this, 
  function(event:CloseEvent):void{
    Alert.show("You pressed " + ((event.detail==Alert.YES)?"delete":"cancel"));
  },
  IconLibrary.WARNING_ICON
);

Notice that before we show the Alert we've changed the labels on the yes and no button. So, in fact it's a bit more powerful than Messagebox ever was.

I can't believe I got this far with Flex without realising this. Things just got a lot easier.

Download?

The download of all the code will come at some point. Be patient. There's just a bit more I want to squeeze in there first.
