Hi guys,

I am developing a flex application for collaborative data analysis. To present the data my application uses standard and custom components (grids, charts etc.).

I want to deliver the feature that allows users making notes over the GUI of my application. So, other users will see they notes late on.

At the moment my question is: How can be implemented mechanism that allows making notes over the GUI? All suggestions and examples are welcome?

A: 

There are a lot of ways to approach this. ( Check out Buzzword, MS Word, and Acrobat all for slightly different approaches of note taking on a document--I assume an application GUI could use any of the same approaches ).

I'd start by saying that the click event bubbles:

So, listen for the click event on every child of your main application file. When you receive that click event you can provide some business logic as to whether or not you want to add a comment /note on the component that was clicked. Then you just some "note" component for collecting and displaying the note data. You an position them based on the x, y values of the click event.

PopUpManager is a simple approach, but I can easily envision it's elegance. I was--obviously--thinking of something more complicated.

So, actually my problem is much easier then I expected (thank for great design of Flex).

I decided to utilize PopUpManager functionality for my task. It does everything I need at the moment.
