Question

I have a JList with a JScrollPane. If I only have one thing in the JList, there will be empty space due to the JScrollPane. If I click anywhere in the JList, it will click the one element. Is there a way to make it only click the element if I actually click it? Also, I am using a custom renderer for the JList to add images, if that has anything to do with it.

Thanks

You can check the index that was clicked via locationToIndex.

Returns the cell index closest to the given location in the list’s
coordinate system. To determine if the cell actually contains the
specified location, compare the point against the cell’s bounds, as
provided by getCellBounds. This method returns -1 if the model is
empty.
