setGraphModel

public void setGraphModel(GanttChartModel newGanttChartModel)
                   throws java.lang.IllegalArgumentException

Sets a GanttChartModel to define most of the GanttChart's display properties. Modifying any GanttChartModel property triggers the GanttChart to update. The update is asynchronous and delayed so modifying multiple properties in quick succession will result in only a single update. Use the FullPaintInterface if greater control over the GanttChart's paint behavior is necessary.

Typically applyGraphStyle is used to modify the graphs display properties.

Parameters:

newGanttChartModel - the GanttChartModel that encapsulates the GanttChart's display properties

Throws:

java.lang.IllegalArgumentException - if newGanttChartModel is null.

See Also:

getGraphModel(), GanttChartModel.apply(com.sas.graphics.components.ganttchart.GanttChartModel), GraphStyle

getGraphModel

public GanttChartModel getGraphModel()

Returns the GanttChartModel that encapsulates most of the GanttChart's display properties.

Returns:

the GanttChartModel that encapsulates most of the GanttChart's display properties

See Also:

setGraphModel(com.sas.graphics.components.ganttchart.GanttChartModel), GanttChartModel.apply(com.sas.graphics.components.ganttchart.GanttChartModel)

setDataModel

public void setDataModel(GanttChartDataModel newDataModel)

Sets the GanttChartDataModel which provides a handle to the data along with any associated mapping properties to define the number and arrangement of data elements (i.e. gantt activity bars), legend and axes.

Any change in the GanttChartDataModel properties will cause the GanttChart to update. The update is asynchronous and delayed so modifying multiple properties in quick succession will result in only a single update. The FullPaintInterface can be used if greater control over the GanttChart's paint behavior is needed.

Note: Data value changes will also trigger GanttChart to update.

A valid GanttChartDataModel is required to draw a graph.

Parameters:

newDataModel - provides a handle to the data along with any associated mapping properties

See Also:

getDataModel(), GanttChartTableDataModel

getDataModel

public GanttChartDataModel getDataModel()

Returns the GanttChartDataModel that provides a handle to the data along with any associated mapping properties.

Returns:

setDisplayPolicy

public void setDisplayPolicy(int newDisplayPolicy)
                      throws java.lang.IllegalArgumentException

Set how the graph is to utilize the display area. The graph will always utilize all the display area supplied to it however there are occasions when the display area provided to the graph is less than optimal size to draw the graph well. Various factors can contribute to this including font selection, data assignments, number of data observations, whether or not the legend is displayed, etc.

When insufficient display area is available, the gantt chart uses scroll bars and only displays a portion of the graph and table.

GraphConstants.DISPLAY_SCROLL_AS_NEEDED is the default behavior and GraphConstants.DISPLAY_AUTOMATIC will behave behave the same way as scroll as needed. Specifing GraphConstants.DISPLAY_SCROLL_ENABLED and GraphConstants.FIT_TO_SCREEN have no meaning to the GanttChart.

The default value is GraphConstants.DISPLAY_SCROLL_AS_NEEDED. Valid values are:
GraphConstants.DISPLAY_SCROLL_AS_NEEDED GraphConstants.DISPLAY_SCROLL_ENABLED: GraphConstants.DISPLAY_AUTOMATIC:

Overrides:

setDisplayPolicy in class Graph

Parameters:

newDisplayPolicy - how the Graph should utilize the dislay area

Throws:

java.lang.IllegalArgumentException - if newDisplayPolicy is invalid.

See Also:

prepareToPaint

public void prepareToPaint()

Notify this component that an application is about to call paint directly. This method is useful when attempting to get the Graph to draw into an image (or other application provided GraphicsContext).

As per java standard practices; "paint" should never be called directly by an application. However if it is necessary to render the Graph directly then the use of paintAll(Graphics) or printAll(Graphics) is acceptable.

Graphs asynchronously update to keep their view in sync with their model properties (Graphmodel, DataModel, NoteModel etc.). A direct call to paintAll or printAll does not allow for the graph to asynchronously sync up with their model proeprties. prepareToPaint provides this synchronization point necessary for the Graphs to update their component structure as needed.

Note: Used in a headless environment, Graphs will never asynchronously update and therefore require a call to prepareToPaint to render into a GraphicsContext.

The headless and non-headless cases can be handled slightly differently. In the non-headless case the asynchronous updating needs to be halted. This is done by setting the "autoRepaintEnabled" property to false. The default for autoRepaintEnabled is true, allowing the graph to automatically resync and repaint as model properties are modified.

Example writing to an image. Note for readability exception handling has been ignored.

 static public void main(String args[])
 {
    BufferedImage bi = new BufferedImage(640,480,BufferedImage.TYPE_INT_RGB);
    Graphics ig = bi.createGraphics();

    // Create Graph
    GanttChart graph = new GanttChart();
 
    // This call is not necessary if you are running in a headless environment.
    graph.setAutoRepaintEnabled(false);
    
    // ... assign data and model properties here ...
    graph.setDataModel(newGraphData());
    
    {// Render sequence
        graph.setBounds(0,0,bi.getWidth(null),bi.getHeight(null)); // Define the size of the Graph
        graph.addNotify(); // Makes the component displayable.
        graph.prepareToPaint(); // do property synchronization
        graph.paintAll(ig); // render into some graphics context
    }
 
    // Dispose of image graphics context
    ig.dispose();                
    
    // Save immage to disk
    File file = new File("graph.jpg");
    try
    {
        ImageIO.write(bi, "jpg", file);
    }
    catch (IOException e)
    {
        System.out.println("ImageIO.write failed.");
    }
 }

prepareToPaint in class Graph

setAutoRepaintEnabled

public void setAutoRepaintEnabled(boolean b)

Sets whether or not the graph automatically repaints when any of its properties (contained in associated models GraphModel, DataModel, NoteModel, etc) has changed. The default value is true.

The setting of this property to false implies that the application will be responsible for synchronizing the graph with its models using the prepareToPaint method.

Note: This method should NOT be used when also allowing interactive table editing. Unreliable results are sure to occur. This method was added to suport rendering into an off screen graphics context such as an image.

Specified by:

setAutoRepaintEnabled in class Graph

Parameters:

b - true means to automatically update

See Also:

isAutoRepaintEnabled()

isAutoRepaintEnabled

public boolean isAutoRepaintEnabled()

Returns whether or not the graph automatically repaints when any of its properties (contained in associated models GraphModel, DataModel, NoteModel, etc) has changed.

Specified by:

isAutoRepaintEnabled in class Graph

See Also:

setAutoRepaintEnabled(boolean)

getExtendedBeanInfo

public static com.sas.beans.ExtendedBeanInfo getExtendedBeanInfo()

Returns information used by the com.sas.beans.Introspector to augment the automatically introspected information about this GanttChart.

Returns:

the ExtendedBeanInfo for this class

applyGraphStyle

public void applyGraphStyle(GraphStyle graphStyle)

Apply the GraphStyle display properties onto the GanttChart. The use of this method is a convenient way to quickly and easily affect the GanttChart's appearance. The GanttChartModel (accessible via the getGraphModel method) properties and the NoteModels (accessible via the getTitle and getFootnote methods) properties are modified by this method.

The GraphStyle enforces certain constraints that are not enforced on the Graph's display models (GanttChartModel and NoteModels). For example only one value text color may be specified on the GraphStyle, whereas the GanttChartModel supports setting different value text colors between axes, legends and data element text. Most presentations only require a single color for all types of value text, which is easily achieved by applying a GraphStyle.

Applying a GraphStyle will modify the display properties of the GanttChartModel and the title and footnote NoteModels. The GanttChart does not retain a link to the GraphStyle after this method has been called. Modifying any of the GraphStyle properties after this method has been called will have no affect on the GanttChart. Similarly modifying any of GanttChart's display properties after this method has been called will have no affect on the GraphStyle properties. To affect any change in the GanttChart display appearance the modified GraphStyle or a different GraphStyle would need to be applied again.

A blind PropertyChangeEvent is fired by the GanttChart after the apply is made.

No action is taken if a null GraphStyle is passed in.

Overrides:

applyGraphStyle in class Graph

Parameters:

graphStyle - the GraphStyle whose properties are conveyed to the GanttChart

See Also:

NoteModel, GanttChartModel
