Method Detail

getBounds

public abstract Rectangle getBounds(TreePath value0, Rectangle value1)

getBounds

Parameters: value0 TODO value1 TODO

Returns: Rectangle

getExpandedState

public abstract boolean getExpandedState(TreePath path)

getExpandedState

Parameters: path the tree path

Returns: boolean

getModel

public TreeModel getModel()

Returns the model that provides the tree data.

Returns: the model

getNodeDimensions

public AbstractLayoutCache.NodeDimensions getNodeDimensions()

getNodeDimensions

Returns: NodeDimensions

getNodeDimensions

protected Rectangle getNodeDimensions(Object value, int row, int depth, boolean expanded, Rectangle bounds)

Get the node dimensions. The NodeDimensions property must be set (unless the method is overridden, like if {@link FixedHeightLayoutCache}. If the method is not overridden and the property is not set, the InternalError is thrown.

Parameters: value the last node in the path row the node row depth the indentation depth expanded true if this node is expanded, false otherwise bounds the area where the tree is displayed

getPathClosestTo

public abstract TreePath getPathClosestTo(int value0, int value1)

getPathClosestTo

Parameters: value0 TODO value1 TODO

Returns: the tree path

getPathForRow

public abstract TreePath getPathForRow(int row)

getPathForRow

Parameters: row the row

Returns: the tree path

getPreferredHeight

public int getPreferredHeight()

Get the sum of heights for all rows. This class provides a general not optimized implementation that is overridded in derived classes ({@link VariableHeightLayoutCache}, {@link FixedHeightLayoutCache}) for the better performance.

getPreferredWidth

public int getPreferredWidth(Rectangle rect)

Get the maximal width. This class provides a general not optimized implementation that is overridded in derived classes ({@link VariableHeightLayoutCache}, {@link FixedHeightLayoutCache}) for the better performance.

Parameters: rect the rectangle that is used during the method work

getRowCount

public abstract int getRowCount()

getRowCount

Returns: the number of rows

getRowForPath

public abstract int getRowForPath(TreePath path)

getRowForPath

Parameters: path the tree path

Returns: the row

getRowHeight

public int getRowHeight()

getRowHeight

Returns: the row height

getRowsForPaths

public int[] getRowsForPaths(TreePath[] paths)

Get the tree row numbers for the given pathes. This method performs the "bulk" conversion that may be faster than mapping pathes one by one. To have the benefit from the bulk conversion, the method must be overridden in the derived classes. The default method delegates work to the {@link #getRowForPath(TreePath)}.

Parameters: paths the tree paths the array of the tree pathes.

Returns: the array of the matching tree rows.
