Method Detail

contentsChanged

public void contentsChanged(IActiveViewEventsContentsChangedEvent theEvent)
                     throws IOException,
                            AutomationException

Fired when the contents of the view changes.

Remarks

The Map object fires this event when a new document is loaded. Adding a new layer to a Map does not trigger this event.

The PageLayout object fires the event when IGraphicsContainer::DeleteAllElements in called and when a new document is loaded.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

contentsChanged in interface IActiveViewEvents

Parameters:

theEvent - The event

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

IActiveView.contentsChanged()

contentsCleared

public void contentsCleared(IActiveViewEventsContentsClearedEvent theEvent)
                     throws IOException,
                            AutomationException

Fired when the contents of the view is cleared.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

contentsCleared in interface IActiveViewEvents

Parameters:

theEvent - The event

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

itemAdded

public void itemAdded(IActiveViewEventsItemAddedEvent theEvent)
               throws IOException,
                      AutomationException

Fired when an item is added to the view.

Remarks

The Map fires the event every time a new layer is added.

The PageLayout fires this event whenever a new element is added to the layout. Elements include not only graphics but data frames as well.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

itemAdded in interface IActiveViewEvents

Parameters:

theEvent - The event

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

itemDeleted

public void itemDeleted(IActiveViewEventsItemDeletedEvent theEvent)
                 throws IOException,
                        AutomationException

Fired when an item is deleted from the view.

Remarks

The PageLayout object fires this event whenever elements are deleted from the layout.

The Map object fires this event when a layer is removed.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

itemDeleted in interface IActiveViewEvents

Parameters:

theEvent - The event

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

itemReordered

public void itemReordered(IActiveViewEventsItemReorderedEvent theEvent)
                   throws IOException,
                          AutomationException

Fired when a view item is reordered.

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.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

itemReordered in interface IActiveViewEvents

Parameters:

theEvent - The event

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

selectionChanged

public void selectionChanged(IActiveViewEventsSelectionChangedEvent theEvent)
                      throws IOException,
                             AutomationException

Call this function to fire the selection changed event.

Windows, Solaris, Linux

Specified by:

selectionChanged in interface IActiveViewEvents

Parameters:

theEvent - The event

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

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.
