All Implemented Interfaces:

public class ParseTreeRenderer
extends javax.swing.JLabel
implements javax.swing.tree.TreeCellRenderer

This class customizes the original source of javax.swing.tree.DefaultTreeCellRenderer for rendering a parse tree display.

Implementation note: (from original DefaultTreeCellRenderer authors) This class overrides validate, revalidate, repaint, and firePropertyChange solely to improve performance. If not overridden, these frequently called methods would execute code paths that are unnecessary for the default tree cell renderer. If you write your own renderer, take care to weigh the benefits and drawbacks of overriding these methods.

getDefaultClosedIcon

public javax.swing.Icon getDefaultClosedIcon()

Returns the default icon, for the current laf, that is used to represent non-leaf nodes that are not expanded.

getDefaultLeafIcon

public javax.swing.Icon getDefaultLeafIcon()

Returns the default icon, for the current laf, that is used to represent leaf nodes.

public javax.swing.Icon getOpenIcon()

Returns the icon used to represent non-leaf nodes that are expanded.

setLeafIcon

public void setLeafIcon(javax.swing.Icon newIcon)

Sets the icon used to represent leaf nodes.

getLeafIcon

public javax.swing.Icon getLeafIcon()

Returns the icon used to represent leaf nodes.

setTextSelectionColor

public void setTextSelectionColor(java.awt.Color newColor)

Sets the color the text is drawn with when the node is selected.

getTextSelectionColor

public java.awt.Color getTextSelectionColor()

Returns the color the text is drawn with when the node is selected.

setTextNonSelectionColor

public void setTextNonSelectionColor(java.awt.Color newColor)

Sets the color the text is drawn with when the node isn't selected.

getTextNonSelectionColor

public java.awt.Color getTextNonSelectionColor()

Returns the color the text is drawn with when the node isn't selected.

setBackgroundSelectionColor

public void setBackgroundSelectionColor(java.awt.Color newColor)

Sets the color to use for the background if node is selected.

getBackgroundSelectionColor

public java.awt.Color getBackgroundSelectionColor()

Returns the color to use for the background if node is selected.

setBackgroundNonSelectionColor

public void setBackgroundNonSelectionColor(java.awt.Color newColor)

Sets the background color to be used for non selected nodes.

getBackgroundNonSelectionColor

public java.awt.Color getBackgroundNonSelectionColor()

Returns the background color to be used for non selected nodes.

setBorderSelectionColor

public void setBorderSelectionColor(java.awt.Color newColor)

Sets the color to use for the border.

getBorderSelectionColor

public java.awt.Color getBorderSelectionColor()

Returns the color the border is drawn.

setFont

public void setFont(java.awt.Font font)

Subclassed to map FontUIResources to null. If font is null, or a FontUIResource, this has the effect of letting the font of the JTree show through. On the other hand, if font is non-null, and not a FontUIResource, the font becomes font.

Overrides:

setFont in class javax.swing.JComponent

setBackground

public void setBackground(java.awt.Color color)

Subclassed to map ColorUIResources to null. If color is null, or a ColorUIResource, this has the effect of letting the background color of the JTree show through. On the other hand, if color is non-null, and not a ColorUIResource, the background becomes color.

Overrides:

setBackground in class javax.swing.JComponent

getTreeCellRendererComponent

public java.awt.Component getTreeCellRendererComponent(javax.swing.JTree tree,
                                              java.lang.Object value,
                                              boolean sel,
                                              boolean expanded,
                                              boolean leaf,
                                              int row,
                                              boolean hasFocus)

Configures the renderer based on the passed in components. The value is set from messaging the tree with convertValueToText, which ultimately invokes toString on value. The foreground color is set based on the selection and the icon is set based on leaf and expanded.

Specified by:

getTreeCellRendererComponent in interface javax.swing.tree.TreeCellRenderer
