Constructor Detail

UpdateThread

public UpdateThread(GISFrame gisFrame,
                    boolean recalcRaster)

Updates the display of changed spatial objects.

Parameters:

gisFrame - Frame identifying spatial objects.

recalcRaster - Indicates whether a raster has been updated and therefore needs redrawing.

UpdateThread

public UpdateThread(GISFrame gisFrame,
                    boolean recalcRaster,
                    String customMessage)

Updates the display of changed spatial objects and reports the given message.

Parameters:

gisFrame - Frame identifying spatial objects.

recalcRaster - Indicates whether a raster has been updated and therefore needs redrawing.

customMessage - Message to display when update completed.

Method Detail

doProcessing

public void doProcessing()

Displays the spatial objects as a threaded process. This is useful to ensure dynamic changes are updated in the user interface.

Note that this method will be called automatically if this is run as a threaded process (e.g. myUpdate.start()). Alternatively it can be called directly as a non-threaded process.

Specified by:

doProcessing in class LSThread
