public AbstractLayoutCache()

Constructor AbstractLayoutCache

public abstract Rectangle getBounds(TreePath value0,
 Rectangle value1)

getBounds

Parameters:

value0 - TODO

value1 - TODO

Returns:

Rectangle

public abstract boolean getExpandedState(TreePath path)

getExpandedState

Parameters:

path - the tree path

Returns:

boolean

public TreeModel getModel()

Returns the model that provides the tree data.

Returns:

the model

public AbstractLayoutCache.NodeDimensions getNodeDimensions()

getNodeDimensions

Returns:

NodeDimensions

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 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

public abstract TreePath getPathClosestTo(int value0,
 int value1)

getPathClosestTo

Parameters:

value0 - TODO

value1 - TODO

Returns:

the tree path

public abstract TreePath getPathForRow(int row)

getPathForRow

Parameters:

row - the row

Returns:

the tree path

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 (VariableHeightLayoutCache, FixedHeightLayoutCache) for the better performance.

public int getPreferredWidth(Rectangle rect)

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

Parameters:

rect - the rectangle that is used during the method work

public abstract int getRowCount()

getRowCount

Returns:

the number of rows

public abstract int getRowForPath(TreePath path)

getRowForPath

Parameters:

path - the tree path

Returns:

the row

public int getRowHeight()

getRowHeight

Returns:

the row height

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 getRowForPath(TreePath).

Specified by:

getRowsForPaths in interface RowMapper

Parameters:

paths - the tree paths the array of the tree pathes.

Returns:

the array of the matching tree rows.

public TreeSelectionModel getSelectionModel()

getSelectionModel

Returns:

the model

public abstract int getVisibleChildCount(TreePath path)

getVisibleChildCount

Parameters:

path - the tree path

Returns:

int

public abstract Enumeration
 getVisiblePathsFrom(TreePath path)

getVisiblePathsFrom

Parameters:

path - the tree path

Returns:

Enumeration

public abstract void invalidatePathBounds(TreePath path)

invalidatePathBounds

Parameters:

path - the tree path

public abstract void invalidateSizes()

invalidateSizes

public abstract boolean isExpanded(TreePath value0)

isExpanded

Parameters:

value0 - TODO

Returns:

boolean

protected boolean isFixedRowHeight()

Returns true if this layout supposes that all rows have the fixed height.

Returns:

boolean true if all rows in the tree must have the fixed height (false by default).

public boolean isRootVisible()

isRootVisible

Returns:

true if root is visible, false otherwise

public abstract void setExpandedState(TreePath value0,
 boolean value1)

setExpandedState

Parameters:

value0 - TODO

value1 - TODO

Sets the model that provides the tree data.

Parameters:

model - the model

public void setNodeDimensions(AbstractLayoutCache.NodeDimensions dimensions)

setNodeDimensions

Parameters:

dimensions - TODO

public void setRootVisible(boolean visible)

setRootVisible

Parameters:

visible - true if root should be visible, false otherwise

public void setRowHeight(int height)

setRowHeight

Parameters:

height - the row height
