JTree.setLargeModel(boolean)

[Jason Cavett]

What is the purpose of JTree.setLargeModel(boolean)? I figured it had
something to do with a large tree model underlying the JTree
(performance improvement or something). Am I right? If so, what is
considered a "large tree model." Are there any disadvantages to
setting this if you have a small tree model?


Thanks

The JTree.LargetModel property affects only if the JTree.RowHeight
property is set to positive value.
The main idea that, if model contains too many nodes, to paint all
tree rows with the same height.
Otherwise, heights of each row would be truly calculated using a tree
node renderer and stored into the cache in the BasicTreeUI class.
