Class TreeCellContext

java.lang.Object

org.jdesktop.swingx.renderer.CellContext

org.jdesktop.swingx.renderer.TreeCellContext

All Implemented Interfaces:

java.io.Serializable

public class TreeCellContext
extends CellContext

Tree specific CellContext.

• PENDING: use focus border as returned from list or table instead of rolling its own? The missing ui-border probably is a consequence of the border hacking as implemented in core default renderer. SwingX has a composite default which should use the "normal" border.
• PENDING: selection colors couple explicitly to SwingX - should we go JXTree as generic type?
• PENDING: for a JXTree use the icons as returned by the xtree api?

Method Detail

installContext

public void installContext(javax.swing.JTree component,
                           java.lang.Object value,
                           int row,
                           int column,
                           boolean selected,
                           boolean focused,
                           boolean expanded,
                           boolean leaf)

Sets state of the cell's context. Note that the component might be null to indicate a cell without a concrete context. All accessors must cope with.

Parameters:

component - the component the cell resides on, might be null

value - the content value of the cell

row - the cell's row index in view coordinates

column - the cell's column index in view coordinates

selected - the cell's selected state

focused - the cell's focused state

expanded - the cell's expanded state

leaf - the cell's leaf state

getComponent

public javax.swing.JTree getComponent()

Description copied from class: CellContext

Returns the component the cell resides on, may be null. Subclasses are expected to override and return the component type they are handling.

Overrides:

getComponent in class CellContext

Returns:

the component the cell resides on, may be null.

getTreePath

public javax.swing.tree.TreePath getTreePath()

Returns the treePath for the row or null if invalid.

isEditable

public boolean isEditable()

Returns the cell's editability. Subclasses should override to return a reasonable cell-related state.

Here: false.

PENDING: implement to return the tree cell editability!

Overrides:

isEditable in class CellContext

Returns:

the cell's editable property.

getIcon

public javax.swing.Icon getIcon()

Returns the icon. Subclasses should override to return a reasonable cell-related state.

Here: null.

Overridden to return a default depending for the leaf/open cell state.

Overrides:

getIcon in class CellContext

Returns:

the cell's icon.
