JFileChooser - multiple selections with mouse

I have a JFileChooser that has multiple selections enabled. The selections are made by clicking on one file, holding the shift key down, and clicking another file. Is there a way to select multiple files using only the mouse (not the shift key), by holding down the mouse button and dragging?

The only way I know of is the shift or ctrl + click to highlight a number of files beginning with the first you select and through the next you select with shift held down.  Holding ctrl allowing you to pick individual files at random.

As you see from the API, when marking and selecting files it will only return ONE objectt.
If you want a more strong file chooser you will either have to make it yourself or use one of the premade ones available though google.

Remember: JFileChooser is a SIMPLE mechanism.

>>it will only return ONE object.
If that one object contains multiple files, no matter how selected, then all is well

>>use one of the premade ones available though google.
I'm not following you here. Google has an API with JFileChoosers?

Simple answer is that JFileChooser doesn't do this at all as far as I know, so answer is NO to your question.
If the thought is to be able to select multiple files using just the mouse, you can take a look at other API's/implementations that may help which is what sirtam may have been eluding too.

One approach is to implement something like this example which allows you to make selections through check boxes.  Since you can check a box with mouse only, would get you to your goal.

I understand that the answer is NO, but I was confused by sirtam's response in that his point that it returns one object seemed irrelevant and that I don't know he meant by "available through google"

I'll take a look at the FileSystemTree.
