/**
* JXTaskPane is a container for tasks and other
* arbitrary components.
*
*
* Several JXTaskPanes are usually grouped together within a
* {@link org.jdesktop.swingx.JXTaskPaneContainer}. However it is not mandatory
* to use a JXTaskPaneContainer as the parent for JXTaskPane. The JXTaskPane can
* be added to any other container. See
* {@link org.jdesktop.swingx.JXTaskPaneContainer} to understand the benefits of
* using it as the parent container.
*
*
* JXTaskPane provides control to expand and
* collapse the content area in order to show or hide the task list. It can have an
* icon, a title and can be marked as
* special. Marking a JXTaskPane as
* special ({@link #setSpecial(boolean)} is only a hint for
* the pluggable UI which will usually paint it differently (by example by
* using another color for the border of the pane).
*
*
* When the JXTaskPane is expanded or collapsed, it will be
* animated with a fade effect. The animated can be disabled on a per
* component basis through {@link #setAnimated(boolean)}.
*
* To disable the animation for all newly created JXTaskPane,
* use the UIManager property:
* UIManager.put("TaskPane.animate", Boolean.FALSE);.
*
*
* Example:
*
*
* JXFrame frame = new JXFrame();
*
* // a container to put all JXTaskPane together
* JXTaskPaneContainer taskPaneContainer = new JXTaskPaneContainer();
*
* // create a first taskPane with common actions
* JXTaskPane actionPane = new JXTaskPane();
* actionPane.setTitle("Files and Folders");
* actionPane.setSpecial(true);
*
* // actions can be added, a hyperlink will be created
* Action renameSelectedFile = createRenameFileAction();
* actionPane.add(renameSelectedFile);
* actionPane.add(createDeleteFileAction());
*
* // add this taskPane to the taskPaneContainer
* taskPaneContainer.add(actionPane);
*
* // create another taskPane, it will show details of the selected file
* JXTaskPane details = new JXTaskPane();
* details.setTitle("Details");
*
* // add standard components to the details taskPane
* JLabel searchLabel = new JLabel("Search:");
* JTextField searchField = new JTextField("");
* details.add(searchLabel);
* details.add(searchField);
*
* taskPaneContainer.add(details);
*
* // put the action list on the left
* frame.add(taskPaneContainer, BorderLayout.EAST);
*
* // and a file browser in the middle
* frame.add(fileBrowser, BorderLayout.CENTER);
*
* frame.pack();
* frame.setVisible(true);
