Method Detail

dynamicMapStarted

public void dynamicMapStarted(IDynamicMapEventsDynamicMapStartedEvent theEvent)
                       throws IOException,
                              AutomationException

Fired when the dynamic map starts.

Description

Fired each time the dynamic map cycle starts, if the Dynamic Map is enabled.

This event is tied to the internal heart beat of the dynamic map and will get fired on every dynamic map heart beat, even if the dynamic map is not being redrawn.

Remarks

The dynamic map heart beat interval is set by the IDynamicMap.DynamicDrawRate property.

This event is useful when a timer mechanism is needed. This event synchronizes with the dynamic map heart beatt, therefore it can be used to implement a navigation mode, by changing the visible bounds and calling the refresh method.

Product Availability

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

Specified by:

dynamicMapStarted in interface IDynamicMapEvents

Parameters:

theEvent - The event

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

dynamicMapFinished

public void dynamicMapFinished(IDynamicMapEventsDynamicMapFinishedEvent theEvent)
                        throws IOException,
                               AutomationException

Fired when the dynamic map finishes.

Description

Fired each time the dynamic map cycle ends, if the Dynamic Map is enabled.

This event is tied to the internal heart beat of the dynamic map and will get fired on every dynamic map heart beat, even if the dynamic map is not being redrawn.

Remarks

The dynamic map heart beat interval is set by the IDynamicMap.DynamicDrawRate property.

This event is useful when a timer mechanism is needed. This event synchronizes with the dynamic map heart beat.

Specified by:

dynamicMapFinished in interface IDynamicMapEvents

Parameters:

theEvent - The event

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

beforeDynamicDraw

public void beforeDynamicDraw(IDynamicMapEventsBeforeDynamicDrawEvent theEvent)
                       throws IOException,
                              AutomationException

Fired before the specified phase is drawn.

Remarks

The BeforeDynamicDraw event is getting fired with two different phases (enum esriDynamicMapDrawPhase). Each phase has a different meaning and usage:

1. esriDMDPDynamicLayers – This is getting fired on each dynamic cycle that the Dynamic Map re-renders the scene. The BeforeDynamicDraw event is fired just before the first layer is rendered, and AfterDynamicDraw event is fired just after the last layer (including any Graphic Layer) is rendered.
   In this context, there is an active OpenGL Rendering context (with a preset rendering volume, viewport, etc).
   Use this context to plug-in any custom dynamic drawings with the DynamicDisplay API as well as with the OpenGL API. This context can be useful in order to draw dynamic elements behind or on top of the Layers and Graphics, which do not need to be associated with a layer.
2. esriDMDPLayers – When the Dynamic Map is sensing that it needs to fetch tiles in order to be able to render the scene, the BeforeDynamicDraw will get fired. When the last missing tile will be available and rendered the AfterDynamicDraw event will get fired.
   Note that it is not valid to use the DynamicDisplay API, nor the OpenGL API in this context, since the OpenGL Rendering Context is not fully setup.
   Use this context if you need to monitor when the Dynamic Map is still in a process of fetching tiles for rendering the display.

Parameters:

theEvent - The event

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

afterDynamicDraw

public void afterDynamicDraw(IDynamicMapEventsAfterDynamicDrawEvent theEvent)
                      throws IOException,
                             AutomationException

Fired after the specified phase is drawn.

Remarks

The AfterDynamicDraw event is getting fired with two different phases (enum esriDynamicMapDrawPhase). Each phase has a different meaning and usage:

• esriDMDPDynamicLayers – This is getting fired on each dynamic cycle that the Dynamic Map re-renders the scene. The BeforeDynamicDraw event is fired just after the last layer (including any Graphic Layer) is rendered. In this context there is an active OpenGL Rendering context (with a preset rendering volume, viewport, etc). Use this context to plug-in any custom dynamic drawings with the DynamicDisplay API as well as with the OpenGL API. This context can be useful in order to draw dynamic elements on top of the Layers and Graphic Layers, which do not need to be associated with a layer, for example - mouse feedback, compass, etc.

• esriDMDPLayers – When the Dynamic Map is sensing that it needs to fetch tiles in order to be able to render the scene, the BeforeDynamicDraw will get fired. When the last missing tile will be available and rendered the AfterDynamicDraw event will get fired.Note that it is not valid to use the DynamicDisplay API, nor the OpenGL API in this context, since the OpenGL Rendering Context is not fully setup. Use this context if you need to monitor when the Dynamic Map is still in a process of fetching tiles for rendering the display.
