                        AutomationException

The interval at which the operation will be interrupted to advance progressors and process messages.

Description

The CheckTime property indicates the frequency the CancelTracker will process any pending Windows (mouse and keyboard) messages. By default the CheckTime is 1000 milliseconds.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

getCheckTime in interface ITrackCancel

Returns:

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

Parameters:

progressor - A reference to a com.esri.arcgis.system.IProgressor (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getProgressor

public IProgressor getProgressor()
                          throws IOException,
                                 AutomationException

The progressor used to show progress during lengthy operations.

Description

Use the Progressor property to bind the CancelTracker with a progress object (for example, a progress bar, a progress dialog or a progress animation) that displays the progress of the lengthy operation. Once the Progressor has been set it will be updated automatically as the operation is executed.

Remarks

If the progressor is a step progressor, the MaxRange should be set to equal the number of iterations that the operation will progress through; this number should also match the number of times Continue will be called in the operation’s innermost loop.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

getProgressor in interface ITrackCancel

Returns:

cancel

public void cancel()
            throws IOException,
                   AutomationException

Cancels the associated operation.

Description

By default a cancel will occur under the following circumstances:

• The Esc key was pressed.
• The space bar was pressed. Use the CancelOnKeyPress property to disable this action.
• The left or right mouse button was pressed. Use the CancelOnClick property to disable this action.

Whether a cancel occurs will depend on when the key or button was pressed and the CheckTime property. For example, if a map redraw was cancelled by a key press then it is possible that some phases of the redraw will complete before the key press is handled.
