public class QueryTreeBrowser extends java.lang.Object
The
QueryTreeBrowser
class implements a Swing graphical user interface to browse the contents ofQueryTreeModel
.The browser is rendered as a tree view of the returned query identifier and a one row tabular representation of the contents of any level that the user selects in the tree. Constructors are provided to either add the browser to a frame and creating the tree and table, or to make use of a pair of existing scrolling panes.
Though a functional browser can be built using this class, to add application-specific behavior to be applied when a user selects from the tree, a sub-class inheriting from this class should be constructed that overrides the
buildTreeSelectionListenerToDoSomethingWithSelectedLevel
method The default implementation is as follows:protected TreeSelectionListener buildTreeSelectionListenerToDoSomethingWithSelectedLevel() { return new TreeSelectionListener() { public void valueChanged(TreeSelectionEvent tse) { TreePath tp = tse.getNewLeadSelectionPath(); if (tp != null) { Object lastPathComponent = tp.getLastPathComponent(); if (lastPathComponent instanceof QueryTreeRecord) { QueryTreeRecord r = (QueryTreeRecord)lastPathComponent; System.err.println("TreeSelectionListener.valueChanged: "+r.getUniqueKeys()); } } } }; }

q
- the query information modelm
- the query tree model (i.e. the results returned from an actual query)content
- content pane will to add scrolling panes containing tree and tabular selection views- Throws:

q
- the query information modelm

getSelectionPaths
public QueryTreeRecord[] getSelectionPaths()
Return the records currently selected.
- Returns:
- the records currently selected
-
buildTreeSelectionListenerToDoSomethingWithSelectedLevel
protected javax.swing.event.TreeSelectionListener buildTreeSelectionListenerToDoSomethingWithSelectedLevel()
Override this method to perform application-specific behavior when an entity is selected in the tree browser.
By default this method dumps the string values of the unique keys to the console for level selection, which is pretty useless.
-
buildTreeSelectionListenerToDisplayAttributesOfSelectedRecord
protected javax.swing.event.TreeSelectionListener buildTreeSelectionListenerToDisplayAttributesOfSelectedRecord(javax.swing.JScrollPane attributeBrowserScrollPane)
By default this method populates the tabular attribute browser when an entity is selected in the tree browser.
Override this method to perform application-specific behavior, perhaps if not all attributes in the query identifer for the selected level are to be displayed, or their values are to be rendered specially. The default implementation renders everything as strings.
- Parameters:
attributeBrowserScrollPane
- the tabular attribute browser
