BUILDING APPLICATIONS WITH VISUAL JAVABEANS
MapBean map;
TOCBean toc;
ToolbarBean toolbar;
JLabel statusLabel;
// Constructor
public MapViewerFrame() {
setTitle("MapViewer");
pageLayout = new PageLayoutBean();
map = new MapBean();
toc = new TOCBean();
toolbar = new ToolbarBean();
statusLabel = new JLabel(" ");
6. In the MapViewerFrame user interface, the toolbar component will occupy
BorderLayout.NORTH, and the pageLayout component will occupy the
BorderLayout.CENTER position.
The BorderLayout.WEST position will be occupied by both the TOC and map
components. To achieve this, create a new method to build a JPanel containing
the two controls with the desired layout:
// New method to build the left panel
private JPanel buildMapTOCPanel() {
JPanel leftPanel = new JPanel();
JPanel bottomPanel = new JPanel();
leftPanel.setLayout(new BorderLayout());
bottomPanel.setLayout(new BorderLayout());
bottomPanel.setPreferredSize(new Dimension(200,200));
bottomPanel.add(map, BorderLayout.CENTER);
leftPanel.add(toc, BorderLayout.CENTER);
leftPanel.add(bottomPanel, BorderLayout.SOUTH);
return leftPanel;
}
7. In the BorderLayout.SOUTH position of the MapViewerFrame, add a JLabel
to act as a status bar. The buildAndShow() method should look like the
following once you have updated it with all layout locations:
public void buildAndShow()throws IOException {
JPanel mapTOCPanel = buildMapTOCPanel();
this.getContentPane().add(toolbar, BorderLayout.NORTH);
this.getContentPane().add(pageLayout, BorderLayout.CENTER);
this.getContentPane().add(mapTOCPanel, BorderLayout.WEST);
this.getContentPane().add(statusLabel, BorderLayout.SOUTH);
}
this.setVisible();
