Enclosing class:

FlatTableUI

private class FlatTableUI.RoundedSelectionGraphics
extends Graphics2DProxy

Because selection painting is done in the cell renderer, it would be necessary to require a FlatLaf specific renderer to implement rounded selection. Using a LaF specific renderer was avoided because often a custom renderer is already used in applications. Then either the rounded selection is not used, or the application has to be changed to extend a FlatLaf renderer.

To solve this, a graphics proxy is used that paints rounded selection if row/column/cell is selected and the renderer wants to fill the background.
