Ram, The component you are trying to create shouldn´t exetend the combobox for two reasons, first you would have to override a lot of the combobox methods and second (and for me the most important) you would break the common sense of how a combobox should behave for example if it doesn´t close when you select an item when it closes? What you are going to show when the user select five items?
If I where you I would make that componente based in the canvas or the vbox container and give it a diferent look form the combobox (after all as I said the feel is alredy diferent), you could use a label and a button (for the closed look) and a list with checkboxes itemEditors (for the opened look) Felipe On Thu, Jun 5, 2008 at 7:31 AM, rviswanathan <[EMAIL PROTECTED]> wrote: > > I am still not clear on how this can be done.
