Sets the current data model. A null value (should be) acceptable.
• getDataModel
public synchronized TreeTableDataModel getDataModel()
Returns the current data model.
See Also: TreeTableDataModel
• getColumnModel
public synchronized ColumnModel getColumnModel()
Retuns the column model
See Also: ColumnModel
• addColumn
public void addColumn(Column aColumn)
Adds a column to the tree table. The column is added at the end.
• addColumnAt
public void addColumnAt(Column aColumn, int aIndex)
Adds a column at the given position. Existing columns may be shifted to the right.
• getColumnHeader
public ColumnHeader getColumnHeader()
Returns the ColumnHeader widget that allows the user to view and manipulate column properties.
• getCaret
public TreePath getCaret()
Returns the last object on which the user clicked. This object is used for keyboard navigation.
• setCaret
void setCaret(TreeNode aNode)
• setCaret
public void setCaret(TreePath aPath)
Sets the last object on which the user clicked. This object is used for keyboard navigation.
• getSelectionManager
public SelectionManager getSelectionManager()
Returns the interface for the tree table's selection manager
• setTreeColumn
public void setTreeColumn(Object aID)
Sets which column in which the tree indention and (eventually) icons appear.
• getTreeColumn
public Object getTreeColumn()
Returns which column in which the tree indention and (eventually) icons appear.
• setIndentLevel
public void setIndentLevel(int aIndent)
Sets the number of pixels each level of the tree is indented (16 or more is currently recommended.)
• getIndentLevel
public int getIndentLevel()
Returns the number of pixels each level of the tree is indented.
• setRowHeight
public void setRowHeight(int aHeight)
Sets a fixed row height. Overrides the per-row sizing feature. A height of 0 enables the per-row sizing feature.
• getRowHeight
public int getRowHeight()
Returns the fixed row height
See Also: setRowHeight
• setFixedHeight
public void setFixedHeight(boolean aFixed)
Sets whether all rows have the same height. Saves a tremendous amount of time if true. Defaults to true.
See Also: isFixedHeight
• isFixedHeight
public boolean isFixedHeight()
Returns whether all rows have the same height. Saves a tremendous amount of time if true.
See Also: setFixedHeight
• setRowMargin
public void setRowMargin(int aMargin)
Does nothing, yet.
• getRowMargin
public int getRowMargin()
Does nothing, yet.
• getShiftRange

• select
public void select(TreePath aPath)
Selects the given TreePath.
• navigateUp
void navigateUp(int aModifiers)
Navigation used for up arrow key. Does reverse in-order traversal, skipping children of collapsed nodes.
• navigateDown
void navigateDown(int aModifiers)
Navigation used for down arrow key. Does in-order traversal, skipping children of collapsed nodes.
• navigateLeft
void navigateLeft(int aModifiers)
Navigation used for left arrow key. First collapses node, then moves to parent
• navigateRight
void navigateRight(int aModifiers)
Navigation used for right arrow key. First expands node, then moves to first child
