hi guys, im looking for something rather specific and since Im not too familiar with java GUI I thought Id ask here. Basically i have a vector of strings that I want to edit as easily as possible. My preferred way would be a combo box (drop down is a plus) where the user can select a value and edit it, he should also be able to add and delete values. Is there something that will take care of all that linked to my vector or do I have to program something myself? Thanks. -CProgrammer

That doesnt have half the features I am looking for. I suppose youre saying thats all there is and I have to program an exstension. Strange seeing as this is a pretty everyday thing, having a list to edit.

There isn't really a "standard" component that directly does what you are wanting. All of the components are more generic than that. JList or JTable would probably provide the best interface, you will need program the add, remove and edit functions yourself. You can directly edit in a JTable. With the JList, you will need to provide a separate text box for the editing.

JComboBox lets you select items and edit them. You'll have to create your own button and listeners to support adding and deleting items.
The code should only be about a half page long max. It's not difficult.

Look into the API.

JComboBox provides data model, which is a container of arbitrary objects. Make that container contain strings.

The default model implementation already implements the even notifications, so the only operations you need to do to support adding/removing items is to call corresponding methods on the model itself.

In addition, you can make this adding/removing by simply attaching an ActionListener to apropriate control, and then decide whether you need to add/remove/edit what the user has entered.

Hmm didn't know about that concept. Thanks.
I admit its not hard to do this yourself using a generic component. However after having program tons of lines of code just for some trivial GUI stuff in my project I got a little tired of it, my bad:)

Thanks for the tips. Will look into all of them.
