Adding menus

The class IlvDashboardMenuBar is a Swing JMenu that accepts a set of IlvDashboardAction instances. It inherits from IlvDiagrammerMenuBar and includes File, Edit, View and Options menus.

The following code example shows how to set an IlvDashboardMenuBar in a Dashboard Editor application.

Example   Adding a menu bar to a Dashboard Editor application

 

dashEd = new IlvDashboardEditor();

IlvDashboardMenuBar menuBar = new IlvDashboardMenuBar(dashEd);

//set the menu for the JFrame

this.setJMenuBar(mbar);

For an example of how to extend IlvDashboardMenuBar to add a new menu bar, see the Dashboard Editor sample. This sample can be found at:

<installdir>/jviews-diagrammer/samples/dashboard/dashboardeditor/src/DashboardEditor.java

Adding toolbars

The ilog.views.dashboard package implements two new toolbars, IlvDashboardEditBar and IlvDashboardBackgroundBar. Both are Swing JToolBars. They accept a set of IlvDashboardAction instances and contain predefined actions to control and edit a dashboard diagram.

IlvDashboardEditBar inherits from IlvDiagrammerEditBar. It controls editing, grouping and duplication functionality.

An IlvDashboardEditBar

IlvDashboardBackgroundBar inherits from IlvGraphicPaletteBar. It sends Dashboard actions to edit background objects in the dashboard diagram.

The IlvDashboardBackgroundBar

IlvDashboardDiagram inherits from IlvDiagrammer. You can use standard Diagrammer toolbars to control objects in a dashboard diagram. For example, IlvDiagrammerViewBar is used for zoom and pan operations.

An IlvDiagrammerViewBar

The following code example shows how to create a toolbar to edit a dashboard diagram.

Example   Add an edit toolbar

 

JPanel panel = new JPanel(new BorderLayout());

 

JPanel panel1 = new JPanel(new IlvBetterFlowLayout(FlowLayout.LEADING, 0, 0));

lvDashboardEditBar editToolBar = new IlvDashboardEditBar();

panel1.add(editToolBar);

IlvDiagrammerViewBar viewToolBar = new IlvDiagrammerViewBar();

panel1.add(viewToolBar);

panel.add(panel1, BorderLayout.NORTH);

 

final IlvDashboardBackgroundBar paletteToolBar =

          new IlvDashboardBackgroundBar(this);

panel.add(paletteToolBar, BorderLayout.SOUTH);

 

pcolors.setClient(new IlvPaletteColorSelector.Client() {

  public void backgroundSelected(Color color) {

    paletteToolBar.setPaletteBackground(color);

  }

  public void foregroundSelected(Color color) {

    paletteToolBar.setPaletteForeground(color);

  }

 

});

Adding the Tree pane

The Dashboard Editor uses IlvDashboardTree to display the order of the symbols in a dashboard diagram. IlvDashboardTree is a Swing JTree, it is used as an alternative way to view and select the objects in the diagram.

An IlvDashboardTree

The following code example shows how to add an IlvDashboardTree to a Dashboard application.

Example   Adding an IlvDashboardTree to a dashboard application

 

URL url = IlvDashboardTree.class.getResource("images/tree.gif");

ImageIcon icon = new ImageIcon(url);

IlvDashboardTree tree = new IlvDashboardTree();

JScrollPane treeScrollPane = new JScrollPane(tree);

IlvDashboardExpandablePane treeFrame = new IlvDashboardExpandablePane("Tree", icon, treeScrollPane);

Adding a Property pane

The class IlvDashboardPropertyPanel contains a Swing JTable that displays the properties of objects selected in the diagram. Use the property sheet to view and edit the properties of a background object or the parameters of a symbol.

An IlvDiagrammerPropertyPanel

The following code example shows how to add an IlvDashboardPropertyPanel to a dashboard application.

Example   Adding an IlvDashboardPropertyPanel instance to a dashboard application

 

url = IlvDiagrammerPropertySheet.class.getResource("images/psheet.gif");

    icon = new ImageIcon(url);

IlvDashboardPropertyPanel ppanel = new IlvDashboardPropertyPanel(this);

 

IlvDashboardExpandablePane psheetFrame =

      new IlvDashboardExpandablePane("Property Sheet", icon, ppanel);

 

IlvDashboardExpandableSplitPane split = new IlvDashboardExpandableSplitPane(treeFrame, psheetFrame);

split.setResizeWeight(0.5);

split.setDividerLocation(300);

Using the Overview pane

IlvDashboardDiagram inherits from IlvDiagrammer. You can use standard Diagrammer panes to control objects in a dashboard diagram. The Dashboard Editor uses IlvDiagrammerOverview to display a reduced view of a dashboard diagram. You can use it with the zoom facility of a diagram component to control which part of a large diagram is visible.

An IlvDiagrammerOverview

The following code example shows how to add an IlvDiagrammerOverview to a dashboard application.

Example   Adding an IlvDiagrammerOverview instance to a dashboard application

 

URL url = IlvDiagrammerOverview.class.getResource("images/overview.gif");

ImageIcon icon = new ImageIcon(url);

IlvDiagrammerOverview overview = new IlvDiagrammerOverview();

 

IlvDashboardExpandablePane overviewFrame = new IlvDashboardExpandablePane("Overview", icon, overview);

 

Using the Palettes pane

The class IlvDashboardSymbolPalette is a Swing JPanel that displays the symbols contained in the open palettes. Use the Palettes pane to:

• View symbols in open palettes.

• Drag symbols from the Palettes pane into a dashboard diagram.

An IlvDashboardSymbolPalette

The following code example shows how to add an IlvDashboardSymbolPalette to a dashboard application.

Example   Adding a symbol palette to a dashboard application

 

url = IlvDiagrammerPropertySheet.class.getResource("images/psheet.gif");

icon = new ImageIcon(url);

 

IlvDashboardSymbolPalette palettePanel = new IlvDashboardSymbolPalette(this);

IlvDashboardExpandablePane paletteFrame =

      new IlvDashboardExpandablePane("Palette", icon, palettePanel);

try {

      loadPalette(new URL("file:data/palettes/palette-example.jar"));

      loadPalette(new URL("file:data/palettes/link.jar"));

      loadPalette(new URL("file:data/palettes/gauge.jar"));

    } catch (Exception e) {

      e.printStackTrace();

    }

 

IlvDashboardExpandableSplitPane split = new IlvDashboardExpandableSplitPane(overviewFrame, paletteFrame);

split.setResizeWeight(0.75);

split.setDividerLocation(150);

return split;
