Hi there,

I'm using NetBeans. I cant figure out how the JPopUpMenu comes on the panel. i have made a panel and when i click on JPopUpMenu and place it on the editor, i cant see anything. It just comes in the other components list . And it doesnt show any property.

The other question is about list. I need to make a dynamic List. The list is like that of MSN . Offline contacts, online contacts. Again the netbeans dont allow me to change the list members. do i have  to write some code for it.

plz help,

...

I am not sure I understand what you mean by saying how the popup menu comes up. It shold be displaed when the user takes the appropriate action. For examples look here: http://javaalmanac.com/egs/javax.swing/Popup.html

For the list, you just create a list reference and then keep adding objects there:

List list = new ArrayList()
list.add("hello");
...

But I am not sure if we are talking about the same lists. What exactly is an MSN list?

ganatra,

Noone will comment if they see that you had not answered to an expert trying to help you. In most cases this means that you do not care for the question (or that you still do not know how the site works). So for receiving faster and better responces, always answer to the experts trying to help you:)

So you need a popup with a table and not a list in it?
Can you post the code that you had written for the popup? How it is shown, how it is initiliased and so on?
