public class IlvDiagrammer
extends JComponent
```
IlvDiagrammer is the main class of the Perforce JViews Diagrammer product. It is the Swing component that lets you display and edit diagrams.
A diagram is a graph containing nodes and (optionally) links between nodes. A diagram is defined by the data that it represents (that is, the set of nodes and links), and by the graphical representation of this data.
The diagram data is described by a data model, similar to the Swing data models. The data model is represented by the IlvSDMModel interface, which defines the set of nodes and links and their attributes. Data models can come from different sources such as XML files or databases, or they can directly represent in-memory application objects. The connection of the diagram component to these data sources is implemented by the IlvDiagrammerDataSource class and its subclasses.
The graphical representation of the diagram is fully customizable through style sheets. A style sheet is a text file containing style rules, each rule defining the graphic objects that represent nodes or links according to their type and their attributes. Style sheets are set using the setStyleSheet method. Diagrammer style sheets use the syntax of CSS level 2. Here is a short extract of a JViews Diagrammer style sheet:
```
   node.activity {
     class : "ilog.views.sdm.graphic.IlvGeneralNode";
     shapeType : "RoundRectangle";
     foreground : "black";
     background : "blue";
   }
 
```
A diagram is described by an instance of the class IlvDiagrammerProject. A project contains a data source configuration and one or more style sheets. Projects are stored to XML files, usually with an .idpr suffix. You set a project through the setProject method. Here is an example of code that creates a diagram component and loads a project file:
```
     IlvDiagrammer diagrammer = new IlvDiagrammer();
     diagrammer.setProject(
         new IlvDiagrammerProject(
             new URL("file:myproject.idpr")));
 
```
The easiest way to create a project file is by using the Designer application. The Designer is an editor that lets you load data from a data source, and then define the style of the nodes and links.
You can also create and customize a diagram through the API. For example, the following code creates a node and adds it to the diagram:
```
    Object town1 = diagrammer.createNode("town");
    diagrammer.setObjectProperty(town1, "x", new Double(100));
    diagrammer.setObjectProperty(town1, "y", new Double(100));
    diagrammer.addObject(town1, null);
 
```
IlvDiagrammer supports editing: you can not only display diagrams, but also edit them interactively. Predefined actions are available to create new nodes and links (see IlvDiagrammerPaletteBar). The IlvDiagrammer class also has a full set of editing methods: cut, copy, paste, undo, redo, and so on.
To help you develop Swing GUIs around a diagram component, Perforce JViews Diagrammer provides a set of application components that are ready to connect to an IlvDiagrammer instance: toolbars and menus containing predefined Swing actions to control and edit the diagram, a property sheet, a tree view, and more. These application components are contained in the ilog.views.diagrammer.application package. This package also contains a ready-to-execute application, IlvDiagrammerApplication, that you can use to view your diagrams and do some simple editing.
The IlvDiagrammer class is a front-end that gives access to the functionality provided by the underlying JViews packages: the Graphic Framework, the Stylable Data Mapper (SDM), and the Graph Layout package. These underlying packages can be accessed directly if you need to use advanced features or if you want to extend the component. For example, the getEngine method lets you access the SDM engine that handles the mapping from the data model to the graphic view.

```
 Diagrammer {
   styleApplicationComponents : "true"; // enable styling on application components
 }
 DiagrammerTree {
   rootLabel : "My Graph"; // set label of root item in tree
 }
 node:DiagrammerTree {
   text : "@name"; // use "name" property as label of items in tree
 }
 node:DiagrammerPropertySheet:type {
   editable : "false"; // set "type"  property for all nodes read-only
 }
 node.activity:DiagrammerTable {
   background : "yellow"; // set yellow background for "activity" nodes in table

  - setAdjusting
```
public void setAdjusting(boolean adjusting)
```
    Starts or stops an editing sequence.
    This method is used to tell the diagram component that a sequence of modifications of the diagram should be considered as a whole. The diagram component will then render the changes more efficiently at the end of the editing sequence.
    For example, to add several objects to the diagram, you should do the following:
```
    diagrammer.setAdjusting(true);
    Object town1 = diagrammer.createNode("town");
    diagrammer.setObjectProperty(town1, "x", new Double(100));
    diagrammer.setObjectProperty(town1, "y", new Double(100));
    diagrammer.addObject(town1, null);
    Object town2 = diagrammer.createNode("town");
    diagrammer.setObjectProperty(town2, "x", new Double(200));
    diagrammer.setObjectProperty(town2, "y", new Double(200));
    diagrammer.addObject(town2, null);
    ...
    diagrammer.setAdjusting(false);
 
```
    Editing sequences can be nested, as long as there is one setAdjusting(false) call for each setAdjusting(true) call. The editing sequence ends at the the topmost setAdjusting(false) call.
    Parameters:
    
    adjusting - If true, and if the diagram component was not already in an editing sequence, a new sequence is started. If false, and if this call matches the first setAdjusting(true), then the editing sequence ends, and the diagram component updates the display.
  - clearAdjusting
```
public void clearAdjusting()
```
    Stop an editing sequence but prevents diagrammer from performing any computation regarding the changes. Use this method in place of setAdjusting(false) to validate model changes without spending time refreshing the modified objects. For example, call this method when the changes do not impact the graphic representations.

  - fitToContents
```
public void fitToContents()
```
    Zooms the diagram in or out so that it fits the view size of the diagram component. See IlvManagerView.fitTransformerToContent(Insets, int) for details. This method computes the zoom factor based on the size of the diagrammer view. Therefore, if the diagrammer is not visible, the method does nothing. See fitToContents(boolean) if you want to call this operation before the diagrammer is visible.
  - fitToContents
```
public void fitToContents(boolean delayUntilShowing)
```
    Zooms the diagram in or out so that it fits the view size of the diagram component. See IlvManagerView.fitTransformerToContent(Insets, int, boolean) for details. This method can be called when the diagrammer view is not yet showing or visible (see Component.isShowing()). If the view is not yet showing but the parameter delayUntilShowing is true, it waits until the view becomes showing before doing the operation. This ensures that the transformer will be adapted to the effective size of the showing view even when called at a nonshowing view.
    
    Parameters:
    
    delayUntilShowing - If true and the view is not yet showing, it waits until the view becomes showing and then fits the transformer to the size. If false or if the view is already showing, it fits the transformer immediately to the size.

    The palette bar is a Diagrammer component that is used as a container for "prototype" nodes and links that can be created interactively in this diagram component. When a node or a link is selected in the palette, the user can click to create a copy of the selected node or link. If the selected object is a node, the user clicks once to define the location of the new node. If the selected object is a link, the user clicks twice to define the new link: once on the source node, and once on the target node.
    
    Parameters:
    
    palette - The Diagrammer component that is used as a palette for this diagram component.
  - getPalette
```
public IlvDiagrammer getPalette()

  - setStickyModes
```
public void setStickyModes(boolean stickyModes)
```
    Specifies whether the operating modes of this diagram component (for example, zoom, create node/link, and edit label) should be "sticky" or not. "Sticky" means that the operating mode stays active until the user activates another mode explicitly. Nonsticky modes are "one shot only". For example, with sticky modes, if the user selects Create node, then each time (s)he clicks in the diagram, a new node is created; (s)he must explicitly stop creating nodes by selecting something else. Without sticky modes, once the first node is created, the diagram component automatically reverts to select mode.
    
    Parameters:
    
    stickyModes - Sets the value of the "sticky modes" flag for the diagram component.
  - setBaseTextDirection
```
public void setBaseTextDirection(int baseTextDirection)
```
    Set default base text direction of Diagrammer. The possible choices are:
    - IlvBidiUtil.COMPONENT_DIRECTION: the base text direction is calculated from the component orientation.
    - IlvBidiUtil.LEFT_TO_RIGHT: the base text direction is left-to-right.
    - IlvBidiUtil.RIGHT_TO_LEFT: the base text direction is right-to-left.
    - IlvBidiUtil.CONTEXTUAL_DIRECTION: the base test direction is determined from the text that is displayed according to the standard Bidi algorithm, if the text contains at least one character with a strong left-to-right or right-to-left direction. If the text doesn't contain any character with a strong direction, the real text direction is determined from the current component orientation of the object.
    When you call this method, it disables reading the base text direction from the CSS specification of the StyleSheet section, that is, the CSS specification StyleSheet { baseTextDirection: ...; } has no effect anymore.
    Parameters:
    
    baseTextDirection - New default base text direction

                                 boolean redraw)
```
    Set default base text direction of Diagrammer. The possible choices are:
    - IlvBidiUtil.COMPONENT_DIRECTION: the base text direction is calculated from the component orientation.
    - IlvBidiUtil.LEFT_TO_RIGHT: the base text direction is left-to-right.
    - IlvBidiUtil.RIGHT_TO_LEFT: the base text direction is right-to-left.
    - IlvBidiUtil.CONTEXTUAL_DIRECTION: the base test direction is determined from the text that is displayed according to the standard Bidi algorithm, if the text contains at least one character with a strong left-to-right or right-to-left direction. If the text doesn't contain any character with a strong direction, the real text direction is determined from the current component orientation of the object.
    When you call this method, it disables reading the base text direction from the CSS specification of the StyleSheet section, that is, the CSS specification StyleSheet { baseTextDirection: ...; } has no effect anymore.
    Parameters:
    
    baseTextDirection - New default base text direction
    
    redraw - Whether to redraw the diagrammer.

  - getCurrentDiagrammer
```
public static IlvDiagrammer getCurrentDiagrammer(Component component)
```
    Returns the current diagram component for the hierarchy that contains the specified component.
    This method is used by the GUI components contained in the ilog.views.diagrammer.application package to determine which diagram component is the current target to which they are connected.
    By default, the current diagram component is managed automatically, so actions and GUI components are automatically connected to the current diagram component.
    The default mechanism assumes that there is at most one "current" diagrammer for each Swing hierarchy whose root is a JRootPane. Swing listeners are setup automatically so that the "current" diagrammer of this hierarchy is changed automatically. This mechanism handles the following situations:
    - you have a JDesktopPane whose internal frames contain different instances of IlvDiagrammer,
    - you have a JTabbedPane whose tabs contain different instances of IlvDiagrammer.
    In these common cases, the current diagrammer is set automatically, so you have nothing else to do.
    In other situations, you can define yourself which component is to be considered as the root of the hierarchy that contains a diagrammer and its associated components. For instance, if you have two JPanel instances, each containing a diagrammer and a toolbar, you can specify that each JPanel must be considered as a root, and be handled independently. For this, you will call setAsRoot(Component) and pass the JPanel as the parameter. You can also use the convenience method setCurrentDiagrammer(toolbar, diagrammer, true), which will find the common ancestor between the toolbar and the diagrammer.
    In some rare situations, you may need to completely manage the current diagram component yourself. To do so, you can disable the automatic mode by calling setAutomaticDiagrammerMode(false). Then you must call setCurrentDiagrammer(Component, IlvDiagrammer, boolean) each time the current diagram component changes.
    Parameters:
    
    component - The component that identifies a hierarchy for which the current diagram component is queried.
    
    Returns:
    
    current diagrammer

    Sets the current diagram component for the hierarchy that contains the specified component.
    This is an advanced method: see getCurrentDiagrammer(java.awt.Component) for explanations.
    This method is similar to the variant setCurrentDiagrammer(Component, IlvDiagrammer), except that it optionally finds the common ancestor of component and diagrammer, and calls setAsRoot(Component) on this common ancestor.
    
    Parameters:
    
    component - The component that identifies a hierarchy for which the current diagram component is queried.
    
    diagrammer - The new current diagram component.

public boolean processServerAction(int x,
                                   int y)
```
    This method can be called when the diagram component is used on the server-side of a web application, to process an action sent by the client-side. Typically, this method is called by the Java Server Faces Diagrammer component when the user clicks on the generated image of the graph in his web browser.
    
    Parameters:
    
    x - The X coordinate of the point where the user clicked on the client-side, in view coordinates.
    
    y - The y coordinate of the point where the user clicked on the client-side, in view coordinates.
    
    Returns:
    
    true if the action was processed, false if the action was not processed.
