Class SceneGraph

java.lang.Object
  extended by com.esri.arcgis.analyst3d.SceneGraph
All Implemented Interfaces:
ISceneGraph, ISceneRendererEvents, IViewers3D, IActiveViewEvents, IConnectionPointContainer, IDisplay, IDisplay3D, IScreenDisplay, IScreenDisplay2, com.esri.arcgis.interop.RemoteObjRef, ISupportErrorInfo, Serializable, EventListener

public class SceneGraph
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, IActiveViewEvents, ISceneRendererEvents, ISceneGraph, IViewers3D, ISupportErrorInfo, IConnectionPointContainer, IScreenDisplay, IScreenDisplay2, IDisplay3D

A container for recording data and events that occur in a scene.

Remarks

SceneGraph is to Scene what MapDisplay is to Map. It's associated with a Scene object, either in ArcScene or in a scene viewer control (or a later version scene control). It handles most of the 3D rendering operations and makes the drawing more efficient.

Remarks

The Map objects only fire this event whenever IMap::MoveLayer is called. In the ArcMap application, this occurs when you reorder layers in the table of contents. The Map will also fire this event when new layers are added.

The PageLayout object fires this event when changing the order of graphics. For example, IGraphicsContainer::BringToFront, PutElementOrder, SendToBack, SendBackward, and BringForward all fire this event. These functions are on ArcMap's Drawing menu under the Order pull right menu. Although the Map object is also a graphics container, it does not fire this event when its graphics are reordered.

viewRefreshed

public void viewRefreshed(IActiveViewEventsViewRefreshedEvent theEvent)
                   throws IOException,
                          AutomationException
Fired when view is refreshed before draw happens.

Description

Method that gets fired in response to IActiveView::Refresh and IActiveView::PartialRefresh.

Remarks

This event is useful in the case where you're watching for something to change in the view and there aren't any specific events for that change (e.g. ContentsChanged, ItemAdded). You can always listen for this method as a last resort. Care must be taken however to be very efficient in your implementation of this event because it will be called quite often.

The event parameters directly coincide with the arguments to IActiveView::PartialRefresh. For additional information about the arguments, see the help for that method.

If the event object connects to both the layout and a map, then the view parameter tells you which object initiated the event.

In an implementation of this method you typically want to check the phase and respond to only one. Otherwise, your code will execute multiple times per drawing sequence.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
viewRefreshed in interface IActiveViewEvents
Parameters:
theEvent - The event
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

afterDraw

public void afterDraw(IActiveViewEventsAfterDrawEvent theEvent)
               throws IOException,
                      AutomationException
Fired after the specified phase is drawn.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
afterDraw in interface IActiveViewEvents
Parameters:
theEvent - The event
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

afterItemDraw

public void afterItemDraw(IActiveViewEventsAfterItemDrawEvent theEvent)
                   throws IOException,
                          AutomationException
Fired after an individual view item is drawn. Example: view items include layers in a map or elements in a page layout.

Remarks

AfterItemDraw can be used to execute after each individual item has drawn. Event firing can be an expensive operation (time consuming) when there are many layers in a map, however. As a result, the AfterItemDraw event is only fired when the IViewManger::VerboseEvents property is set to True. By default this property is False.

Parameters:
hWnd - The hWnd (A COM typedef) (in)
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

getHWnd

public int getHWnd()
            throws IOException,
                   AutomationException
Associated window handle.

Remarks

The hWnd property tells ScreenDisplay objects which window to draw in. When a new view (a Map or PageLayout) is created and activated (IActiveView::Activate), a related ScreenDisplay is created and its hWnd is set to that of the main application. Data windows, such as the MapInsetWindow, also have a related ScreenDisplay object and in this case the ScreenDisplay's hWnd property is set so that all drawing will occur in the data window and not the main application window.

Several Windows API calls require an hWnd in order to perform their operation; this property provides the hWnd for the ScreenDisplay object you are currently working with. For example, several of ArcMap's zoom commands use the Windows API function 'GetClientRect' to get the coordinates of the main window's client area. GetClientRect requires the hWnd of the window of interest and in ArcMap's case, IScreenDisplay::hWnd holds this.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
getHWnd in interface IScreenDisplay
Specified by:
getHWnd in interface IScreenDisplay2
Returns:

Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

getWindowDC

public int getWindowDC()
                throws IOException,
                       AutomationException
Device context for the associated window. Only use this between calls to StartDrawing and FinishDrawing.

Remarks

This property is a Windows operating environment device context handle. The Windows operating environment manages the system display by assigning a device context for each window in the application. You can use the WindowDC property to refer to the handle for an object's device context.

This property does not provide a value to pass to IDisplay::StartDrawing. Instead, call IDisplay::StartDrawing with a value of 0 for the hDC as this will automatically use the Windows API function GetDC to populate IScreenDisplay::WindowDC with the hDC of the main display and drawing will occur there.

The value of the WindowDC property can change while an application runs, so do not store the value in a variable; instead, use the WindowDC property each time you need it.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
getWindowDC in interface IScreenDisplay
Specified by:
getWindowDC in interface IScreenDisplay2

addCache

public short addCache()
               throws IOException,
                      AutomationException
Creates a new cache and return its ID. The ID can be specified to StartDrawing to direct output to the cache. It can also be used with a number of other methods such as DrawCache and Invalidate.

Remarks

ScreenDisplay objects make it possible for clients to create any number of caches. A cache is an off screen bitmap representing the application's window. Instead of drawing directly to the screen, graphics are drawn into caches, then the caches are drawn on the screen. When the application's window is obscured and requires redrawing, it done so from the caches instead of from a database. In this way, caches improve drawing performance - bitmap rendering is faster than reading and displaying data from a database.

In general, a Map object creates three caches: one for all the layers, another if there are annotation or graphics, and a third cache if there is a feature selection. A layer can create its own private cache if it sets ILayer::Cached equal to TRUE. In this case, the Map will create a separate cache for the layer and groups the layers above and below it into different caches.

The AppDisplay object has no implementation for this method.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
addCache in interface IScreenDisplay

                 throws IOException,
                        AutomationException
Removes the specified cache.

Remarks

Use this method to remove a cache that is no longer needed. For example, calling the IActiveView::PartialRefresh method on a Map object will delete the Map's selection cache if one exists and there are no features selected.

The AppDisplay object has no implementation for this method.

Remarks

Use this property to loop through all of the available screen caches. For example, if you Invalidate using esriAllScreenCaches, this property is used to loop through all of the caches to invalidate each one.

The AppDisplay object has no implementation for this method.

startRecording

public void startRecording()
                    throws IOException,
                           AutomationException
Starts recording all output to the recording cache.

Remarks

In addition to the caches clients create, the ScreenDisplay object also provides a recording cache that accumulates all drawing that happens on the display. This recording cache is used to redraw the application when the application is moved or exposed or when drawing rubber banding.

Note, StartRecording and StopRecording are exposed for developers creating custom applications that draw from multiple caches and need to refresh quickly. If you are working with ArcMap or even the Map object, leave all cache management up to the Map.

Use StartRecording to let the display know exactly what to record. Use DrawCache(esriScreenRecording) to display the recording cache. Use CacheMemDC(esriScreenRecording) to get a handle to the memory device context for the recording bitmap.

The following C++ code excerpt is a drawing sequence example that uses StartRecording.

VARIANT_BOOL isCacheDirty;

m_ipScreen->IsCacheDirty(esriScreenRecording, &isCacheDirty);



if (isCacheDirty) // draw from scratch

{

  m_ipScreen->StartRecording();

  m_ipScreen->StartDrawing((OLE_HANDLE)hPaintDC, esriNoScreenCache);

  DrawContents();

  m_ipScreen->FinishDrawing();

  m_ipScreen->StopRecording();

}

  else // draw from offscreen bitmap

{

  m_ipScreen->DrawCache((OLE_HANDLE)hPaintDC, esriScreenRecording, 0, 0);

}

Example:

The following java code gives you an example drawing sequence.

IScreenDisplay pScreen;

        boolean isCacheDirty = pScreen.isCacheDirty(esriScreenRecording);

        if (isCacheDirty) // draw from scratch

                        throws IOException,
                               AutomationException
Indicates if scrollbars should appear.

Remarks

IActiveView::ShowScrollBars redirects all its calls to this property.

Changes to this property are not reflected until the active view changes. For example, when in layout view in ArcMap, programmatically changing the PageLayout to not show its scrollbars will have no effect until the next time the active view is set to the PageLayout; calling IActiveView::Refresh has no effect.

ArcMap uses this property to hide the Map's scroll bars when in layout view. Programmatically trying to display a Map's scroll bar in layout view will have no effect; for Map's this setting is only honored in data view and again it requires an active view change before the setting is reflected in the applications window.

Remarks

If a Map's ScaleContents property is set to TRUE, when its display is resized, the area shown stays the same and the scale changes. When set to FALSE, the scale of the Map stays the same and the area shown changes.

The PageLayout object works similarly. If set to TRUE, the contents are stretched when the display is resized. The scale of all maps changes. When set to FALSE, the page remains the same size.

In ArcMap, on the Tools/Options menu, there are check boxes for controlling this property for the data and layout view.

isFramed

public boolean isFramed()
                 throws IOException,
                        AutomationException
Indicates if drawing occurs in a frame rather than on the whole window.

Remarks

When creating a custom application, if you want the display to take over the window it's drawing in, set IsFramed to FALSE. This will add scrollbars (IScreenDisplay::UseScrollBars = TRUE) as necessary and keeps the device frame in sync with the window extent. Setting IsFramed to TRUE means that the display is drawing on some extent within the window. In this case, it won't show scrollbars and it won't automatically update the device frame.

For example, in the ArcMap application, in layout view where each Map resides inside a separate MapFrame, each Map has it IsFramed property set to TRUE. In data view, the opposite is true, a Map's display fits the entire window; in this view, all Map's have IsFramed set to FALSE, not just the focus map.

The IsFramed property also sets the IsFirstCacheTransparent property. When a Map is drawing in layout view, the PageLayout object has its ScreenDisplay and each Map has its own separate ScreenDisplay. This means that the layout has it's display cache(s) and the maps have their own. If the bottom cache of each map was opaque, you wouldn't be able to see through a map onto layout elements below it. Setting IsFirstCacheTransparent on the maps in layout view lets you see through the maps.

If you are working with Map's inside of ArcMap these settings should not be touched. Only use this property when building a low level application that uses a display to draw on a frame on a window.

invalidate

                       boolean erase,
                       short cacheIndex)
                throws IOException,
                       AutomationException
Cause the specified area of the specified cache to redraw.

Remarks

Use Invalidate to refresh a specific region on the display. For example, if you add a new feature, only the extent of the new feature requires refreshing; the remainder of the display can redraw from cache.

The rect parameter specifies the region to update. Use 'Nothing' in Visual Basic or a zero in C++ to invalidate the entire display.

Erase specifies whether or not the background within the update region is erased when the update region is processed. Usually this is set to TRUE.

CacheIndex controls which cache to update. Use IActiveView::ScreenCacheID to get the cache index for a specific draw phase. The valid draw phases are held in the esriViewDrawPhase enumeration and are as follows:

0 - esriViewNone
1 - esriViewBackground
2 - esriViewGeography
4 - esriViewGeoSelection
8 - esriViewGraphics
16 - esriViewGraphicSelection
32 - esriviewForeground

You can also specify esriAllScreenCaches, esriNoScreenCache, and esriScreenRecording.

Invalidate sets the cache(s) as dirty. Use IsCacheDirty to check the state of a particular cache.

After completion, Invalidate fires the IDisplayEvents::DisplayInvalidated event.

IActiveView::PartialRefresh has similar parameters and itself calls Invalidate. Use this method instead as much as possible as it automatically determines the cache index based on the phase provided.

Remarks

Redrawing data from scratch is time consuming compared to drawing data that has been cached in an off-screen bitmap. If a particular cache return FALSE for IsCacheDirty, use DrawCache to instantly redraw the bitmap.

trackPan

public void trackPan()
              throws IOException,
                     AutomationException
Interactively pans the screen.

Remarks

There are two approaches to panning - this method, and the group PanStart, PanMoveTo, and PanStop. This method is the easiest to use as it takes care of all the mouse events and refreshing the display when pan is complete.

Call this method in the mouse down event and make certain you have a reference to the correct ScreenDisplay object. For example, if you are in layout view and you want to pan just the focus map, do not use the ScreenDisplay object associated with IMxDocument::ActiveView. Instead, get the focus Map via IMxDocument::FocusMap, and then get its ScreenDisplay.

Example:

MapControl mapControl; 
IActiveView pActiveView = mapControl.getActiveView();        
IScreenDisplay pScreenDisplay = pActiveView.getScreenDisplay();        
pScreenDisplay.trackPan();

                        AutomationException
Interactively rotates the screen.

Remarks

There are two approaches to rotating the display - this method and the group RotateStart, RotateMoveTo, RotateTimer, and RotateStop. This method is the easiest to use as it takes care of all the mouse events automatically, performs the final display rotation, and invalidates the display.

Call this method in the mouse down event and make certain you have a reference to the correct ScreenDisplay object. For example, if you are in layout view and you want to pan just the focus map, do not use the ScreenDisplay object associated with IMxDocument::ActiveView. Instead, get the focus Map via IMxDocument::FocusMap, and then get its ScreenDisplay.

Example:

The following java code excerpt shows this.

MapControl mapControl; 
IActiveView pActiveView = mapControl.getActiveView();        
IScreenDisplay pScreenDisplay = pActiveView.getScreenDisplay();       
pScreenDisplay.trackRotate();

Remarks

Use UpdateWindow to process pending Windows WM_PAINT messages immediately. This may be the case if you have a routine that takes a long time to execute and you need the window to refresh while the code executes. Typically, no drawing will occur until all your code has been executed and control returns to the ArcMap's message loop and the WM_PAINT message is handled. UpdateWindow forces the window to invalidate by sending a WM_PAINT message directly to the window; the normal ArcMap message queue is bypassed.

startDrawing

public void startDrawing(int hDC,
                         short cacheID)
                  throws IOException,
                         AutomationException
Prepare the display for drawing. Specify the device context and the cache to draw to (normally esriNoScreenCache). The ScreenDisplay coclass will automatically create a window device context if you specify hdc = 0.

Remarks

StartDrawing and FinishDrawing are used to manage clipping, symbols, and caching. Call StartDrawing and FinishDrawing anytime you want to draw to a device such as a display, printer, or cache (bitmap). However, if you are drawing in response to IActiveViewEvents::AfterDraw, the Map object automatically makes these calls for you.

StartDrawing has two parameters: hDc and cacheID. The hDc parameter specifies the target device where drawing will occur, usually a display, printer, or bitmap. The cacheID parameter activates a specific cache. In most cases, esriNoScreenCache should be used.

Specifying a cache sets it as the screen's active cache. When esriNoScreenCache is used, it sets the display's active cache to zero and drawing occurs directly in the device. Specify a cache when you don't want to draw to a screen directly and you instead want to draw to a cache (bitmap) that may ultimately be copied to the screen. For example, when ArcMap draws geography, it draws it to a specific cache and then the cache is copied to the screen. When the screen repaints, instead of drawing all the data from scratch again, the software checks if the cache is dirty or not and simply redraws the bitmap to save time if it can. When drawing to a cache, the hDc parameter should be the device context of the bitmap, use the IScreenDisplay::CacheMemDC property to get a particular cache's hDC.

Each time you need to change the cache you are drawing to, you must do so inside a new StartDrawing / FinishDrawing block. For example, ArcMap usually creates three caches: one for geography layers, one for graphics and annotation, and one for selections. ArcMap draws each of these phases within a separate StartDrawing / FinishDrawing block.

There are times when may need to draw shapes directly to screen without having them become part of a display cache. For example, drawing moving objects. In these cases, use IScreenDisplay::WindowDC to get the device context of the display and esriNoScreenCache as the cacheID.

If a zero is specified for the hDc parameter, the Windows API function GetDC is used to populate IScreenDisplay::WindowDC with the hDC of the main display and drawing is sent here.

As mentioned above, if you drawing in response to the IActiveView::AfterDraw event, the Map object calls StartDrawing and StopDrawing for you. Also, if the draw phase you are drawing after is cached, your drawings will be cached as well.
StartDrawing fires the IDisplayEvents::DisplayStarted event.

Example:

The following java code gives you an example drawing sequence.

<font face=”Courier New” size=2>
<pre>
IScreenDisplay pScreen;
boolean isCacheDirty = pScreen.isCacheDirty(esriScreenRecording);
if (isCacheDirty) // draw from scratch
{
IDisplay pIDisplay = new IDisplayProxy(pScreen);
pScreen.startRecording();
pIDisplay.startDrawing((int)hPaintDC, esriNoScreenCache);
DrawContents();
pScreen.finishDrawing();
pScreen.stopRecording();
} else // draw from offscreen bitmap
{
pScreen.drawCache((int)hPaintDC, esriScreenRecording, 0, 0);
}

getHDC

public int getHDC()
           throws IOException,
                  AutomationException
The device context that the display is currently drawing to. Only valid between calls to StartDrawing and FinishDrawing.

Remarks

Returns the device context specified to StartDrawing. This may be the device context of a display, cache (bitmap), or some other device such as a printer. As StartDrawing is called frequently throughout the drawing pipeline, the hDc property continually changes and is therefore safe to use only within a single StartDrawing / FinishDrawing block.

This property does not provide a value to pass to IDisplay::StartDrawing. Instead, call IDisplay::StartDrawing with a value of 0 for the hDC as this will automatically use the Windows API function GetDC to populate IScreenDisplay::WindowDC with the hDC of the main display and drawing will occur there.
