Constructor Summary

Constructors

Constructor and Description
NodeRenderer() Creates default renderer.
NodeRenderer(boolean bigIcons) Deprecated. bigIcons was only used by IconView, and not used by that anymore. NodeRenderer will automatically detect if the view it's rendering for is an instance of IconView.

Method Summary

Modifier and Type	Method and Description
Component	getListCellRendererComponent(JList list, Object value, int index, boolean sel, boolean cellHasFocus) This is the only method defined by ListCellRenderer.
Component	getTreeCellRendererComponent(JTree tree, Object value, boolean sel, boolean expanded, boolean leaf, int row, boolean hasFocus) Finds the component that is capable of drawing the cell in a tree.
boolean	isShowIcons()
void	setShowIcons(boolean showIcons)
static NodeRenderer	sharedInstance() Deprecated. This method no longer returns a shared instance, as it caused problems with one view setting properties (such as enabled state) on the renderer and the renderer then being used in its altered state by a different view. Views should create their own instance of NodeRenderer instead.
