TreeCellRenderer

[Aaron Fude]

Hi,

I have largely figured out how to us a custom TreeCellRenderer, but I
can't figure out how to make the tree let my custom Components take more
space. I create an JPanel that's about 100x100, but when displayed, only
a small portion of it is displayed, as if it were just a small label.

Any ideas on how to fix it?

Thanks,

Aaron

Have a look at setRowHeight():

I made a TreeCellRenderer that displays thumbnails of .jpgs on my hard
disc. I just made an ImageIcon and put it in a JLabel. Each row of the
JTree can be a different size as a result (the ImageIcon is scaled to be
have the same proportions as the original image) and it works fine.

I'd guess this has something to do with returning "getPreferredSize" and
related methods correctly.

I think we'll need an SSCCE if you continue to have issues.
