Constructor Detail

OpenJMSObject

public OpenJMSObject(java.lang.String destinationName,
                     javax.swing.JTree tree)

getAllowsChildren

public boolean getAllowsChildren()

Children are allowed for all objects

Overrides:

getAllowsChildren in class javax.swing.tree.DefaultMutableTreeNode

Returns:

boolean Always returns true.

isLeaf

public boolean isLeaf()

Objects are leaves iff they have nothing registered against them.

Overrides:

isLeaf in class javax.swing.tree.DefaultMutableTreeNode

Returns:

boolean true if no objects are registered.

displayCommands

public void displayCommands(java.awt.Rectangle loc)
