Method Detail

setRootNodeLabel

public void setRootNodeLabel(java.lang.String nuRootNodeLabel)

Set the label of the root node in the tree.

Parameters:

nuRootNodeLabel - label of the root node

See Also:

getRootNodeLabel()

getRootNodeLabel

public java.lang.String getRootNodeLabel()

Returns the label of the root node in the tree.

Returns:

the label of the root node

See Also:

setRootNodeLabel(String nuRootNodeLabel)

setTreeControl

public void setTreeControl(TreeControl nuTreeControl)

getTreeControl

public TreeControl getTreeControl()

setNodeDefinitions

public void setNodeDefinitions(TreeNodeDef[] defs)

Sets the node definitions.

A node is defined by the DataItem supplying the data, the column linking to the child node and the column that is displayed.

The node definitions is as follows:

• data item name - the name of the RowsetAccess supplying data
• link column name - the column linking to child nodes
• display column name - the column whose value is displayed

The self-referential property will be set to false if the length of def is greater than 1.

Parameters:

defs - an array of arrays of Strings listing the node definition

See Also:

getNodeDefinitions(), setSelfReferential(boolean selfReferential)

getNodeDefinitions

public TreeNodeDef[] getNodeDefinitions()

Returns the node definitions.

A node is defined by the DataItem supplying the data, the column linking to the child node and the column that is displayed.

The node definitions is as follows:

• data item name - the name of the RowsetAccess supplying data
• link column name - the column linking to child nodes
• display column name - the column whose value is displayed

Returns:

an array of arrays of Strings listing the node definition

See Also:

#setNodeDefinitions(String[][3] defs)

setSelfReferential

public void setSelfReferential(boolean selfReferential)

Sets whether the nodes definitions are self-referential.

A self-referential relationship is one where the link column points to another node of the same "shape". Generally speaking, when the node definitions define a self-referential relationship, there should be only a single node definition.

Parameters:

selfReferential - whether the nodes definitions are self-referential.

See Also:

isSelfReferential(), #setNodeDefinitions(String[][3] defs), getNodeDefinitions()

isSelfReferential

public boolean isSelfReferential()

Returns whether the nodes definitions are self-referential.

A self-referential relationship is one where the link column points to another node of the same "shape". Generally speaking, when the node definitions define a self-referential relationship, there should be only a single node definition.

Returns:

whether the nodes definitions are self-referential.

valueForPathChanged

public void valueForPathChanged(javax.swing.tree.TreePath tp,
                                java.lang.Object newValue)
