Constructor Detail

TreeAdapter

public TreeAdapter(JXTree component)

Constructs a TableCellRenderContext for the specified target component.

Parameters:

component - the target component

Method Detail

getTree

public JXTree getTree()

hasFocus

public boolean hasFocus()

Returns true if the cell identified by this adapter currently has focus. Otherwise, it returns false.

Specified by:

hasFocus in class ComponentAdapter

Returns:

true if the cell identified by this adapter currently has focus; Otherwise, return false

getValueAt

public Object getValueAt(int row,
                         int column)

Returns the value of the target component's cell identified by the specified row and column in model coordinates.

Specified by:

getValueAt in class ComponentAdapter

Parameters:

row - in model coordinates

column - in model coordinates

Returns:

the value of the target component's cell identified by the specified row and column

getStringAt

public String getStringAt(int row,
                          int column)

Returns the String representation of the value of the cell identified by the row specified row and column in model coordinates.

This implementation messages the StringValue.TO_STRING with the valueAt, subclasses should re-implement and use the api appropriate for the target component type.

Overrides:

getStringAt in class ComponentAdapter

Parameters:

row - in model coordinates

column - in model coordinates

Returns:

the value of the target component's cell identified by the specified row and column

getCellBounds

public Rectangle getCellBounds()

Returns the bounds of the cell identified by this adapter.

Overrides:

getCellBounds in class ComponentAdapter

Returns:

the bounds of the cell identified by this adapter

isEditable

public boolean isEditable()

Returns true if the cell identified by this adapter is editable, false otherwise.

Specified by:

isEditable in class ComponentAdapter

Returns:

true if the cell is editable, false otherwise

isSelected

public boolean isSelected()

Returns true if the cell identified by this adapter is currently selected. Otherwise, it returns false.

Specified by:

isSelected in class ComponentAdapter

Returns:

true if the cell identified by this adapter is currently selected; Otherwise, return false

isExpanded

public boolean isExpanded()

Returns true if the cell identified by this adapter is currently expanded. Otherwise, it returns false. For components that do not support hierarchical data, this method always returns true because the cells in such components can never be collapsed.

Overrides:

isExpanded in class ComponentAdapter

Returns:

true if the cell identified by this adapter is currently expanded; Otherwise, return false

getDepth

public int getDepth()

Returns the depth of this row in the hierarchy where the root is 0. For components that do not contain hierarchical data, this method returns 1.

Overrides:

getDepth in class ComponentAdapter

Returns:

the depth for this adapter

isHierarchical

public boolean isHierarchical()

Returns true if the cell identified by this adapter displays the hierarchical node. Otherwise, it returns false. For components that do not support hierarchical data, this method always returns false because the cells in such components can never have children.

Overrides:

isHierarchical in class ComponentAdapter

Returns:

true if the cell identified by this adapter displays the hierarchical node; Otherwise, return false

isLeaf

public boolean isLeaf()

Returns true if the cell identified by this adapter is a leaf node. Otherwise, it returns false. For components that do not support hierarchical data, this method always returns true because the cells in such components can never have children.

Overrides:

isLeaf in class ComponentAdapter

Returns:

true if the cell identified by this adapter is a leaf node; Otherwise, return false

isCellEditable

public boolean isCellEditable(int row,
                              int column)

Determines whether this cell is editable.

Specified by:

isCellEditable in class ComponentAdapter

Parameters:

row - the row to query in model coordinates

column - the column to query in model coordinates

Returns:

true if the cell is editable, false otherwise
