help with JCombox

[peace_comp]

Peace..
hey ..well I just need to know if there is a special methode in jcomobox to test if an item already exist in the list before we add it..

I could use a sample loop to compare between each Item in the Comobox with the item i wanna add ..(if one of them return a true boolean means that it exist)..but it won't be a good idea if the list is so long ..
but is there already a methode tu use directly to get if a value (or item) exist in the combobox..???

I had this problem when I try put a columns values into a jcombobox (when a user click on a button)..but if he clicks many times the same values are repeated in the list ???
thanks

The method would not be in the JComboBox itself, but in the "Model" you are using to serve up the data which is displayed in the JComboBox. There are straight-forward ways to determine whether an element exists in the data container before you add that element, and to make sure you are allowing only one - - the standard implementation of a Set, and any container will permit you to generate an Array from the elements in the container to serve as the Model for your JComboBox.
