Method Details

canStartZoomArea
Can a zoom area be started ?This is called from the zoomer when a zoom area is about to start to check that there are not reasons for not starting the area. For instance if some other mouse event is to take priority over the zoom, e.g. clicking on a detection which might initiate some other menu action.
- Parameters:
 mouseEvent-- Returns:
 - true if zooming can start
 
 - 
zoomShapeChanging
Called as the zoom shape changes via some sort of mouse action.- Parameters:
 zoomShape- shape that's changing.
 - 
zoomPolygonComplete
Called when a zoom shape has been completed.- Parameters:
 zoomShape- zoom shape that's completed.
 - 
getXStart
double getXStart()- Returns:
 - start (left most) value on the x axis scale
 
 - 
getXScale
double getXScale()- Returns:
 - x scale in pixels per unit
 
 - 
getXRange
double getXRange()- Returns:
 - range of x axis
 
 - 
getYStart
double getYStart()- Returns:
 - start (bottom most) value on the y axis scale
 
 - 
getYScale
double getYScale()- Returns:
 - y scale in pixels per unit
 
 - 
getYRange
double getYRange()- Returns:
 - the range of the y axis
 
 - 
getCoordinateType
int getCoordinateType()- Returns:
 - the coordinate type - can be pretty much anything so long as it is unique for different types of coordinate for that display, e.g. the Click bearing time display so that zooming can only take place in that coordinate system.
 
 - 
zoomToShape
Zoom to the bounds of a particular shape.- Parameters:
 zoomShape- shape to zoom to
