public DrawMouseViewListener(ROIDataModel roiManagerPanel)

Method Detail

pointFixed

public void pointFixed(MeasureEvent event)
                throws BehaviorException

Description copied from interface: PolylineListener

Called when user executes a mouse click and selects a vertex of the polyline.

Specified by:

pointFixed in interface PolylineListener

Parameters:

event - information about the mouse event, and geometry data of the polyline

Throws:

BehaviorException - will be thrown when fails the process of this tool

points

public void points(MeasureEvent event)
            throws BehaviorException

Description copied from interface: PolylineListener

Called when user moves the mouse after selecting a vertex of the polyline.

Each kind of polyline listener calculates different information with the data of the MeasureEvent, according its nature.

Specified by:

points in interface PolylineListener

Parameters:

event - information about the mouse event, and geometry data of the polyline

Throws:

BehaviorException - will be thrown when fails the process of this tool

polylineFinished

public void polylineFinished(MeasureEvent event)
                      throws BehaviorException

Description copied from interface: PolylineListener

Called when user executes a double click with the mouse, finishing the drawn of the polyline.

All features of the active and vector layers of the associated MapControl object that their area intersect with the polygonal area defined in the event, will be selected.

Specified by:

polylineFinished in interface PolylineListener

Parameters:

event - information about the mouse event, and geometry data of the polyline

Throws:

BehaviorException - will be thrown when fails the process of this tool

cancelDrawing

public boolean cancelDrawing()

Description copied from interface: ToolListener

Determines if the drawing process that this tool executes on the MapControl instance could be canceled or not.

Specified by:

cancelDrawing in interface ToolListener

Returns:

true if is cancellable; otherwise returns false

getImageCursor

public java.awt.Image getImageCursor()

Description copied from interface: ToolListener

Gets the Cursor associated to this tool.

Specified by:

getImageCursor in interface ToolListener

Returns:

component with the bitmap associated to this tool

point

public void point(PointEvent event)
           throws BehaviorException

Description copied from interface: PointListener

Called when one click is pressed on the associated MapControl, or the location of the cursor of the mouse has changed on it.

Specified by:

point in interface PointListener

Parameters:

event - mouse event with the coordinates of the point selected on the associated MapControl

Throws:

BehaviorException - will be thrown when fails the process of this tool

pointDoubleClick

public void pointDoubleClick(PointEvent event)
                      throws BehaviorException

Description copied from interface: PointListener

Called when a double click is pressed on the associated MapControl.

Specified by:

pointDoubleClick in interface PointListener

Parameters:

event - mouse event and the coordinates of the point selected on the associated MapControl

Throws:

BehaviorException - will be thrown when fails the process of this tool
