Constructor Detail

MapCanvas

public MapCanvas(int gd,
                 Frame f,
                 SVar mv,
                 SMarker mark)

Method Detail

updateObjects

public void updateObjects()

Description copied from class: BaseCanvas

rebuilds plot primitives - subclasses should override this method. It is not defined as abstract only for convenience, but minimal subclass simply overrides this method.

Overrides:

updateObjects in class BaseCanvas

queryObject

public String queryObject(int i)

Overrides:

queryObject in class BaseCanvas

keyTyped

public void keyTyped(KeyEvent e)

Specified by:

keyTyped in interface KeyListener

Overrides:

keyTyped in class BaseCanvas

run

public Object run(Object o,
                  String cmd)

Description copied from class: PGSCanvas

default handing of commands "exportPGS" and "exportPS". Any descendant should call super.run(o,cmd) to retain this functionality

Specified by:

run in interface Commander

Overrides:

run in class BaseCanvas

Parameters:

o - origin of the command

cmd - command string

Returns:

any object, the actual interpretation is up to the calling object

getData

public SVar getData(int id)

Description copied from class: PGSCanvas

this method provides an API to fetch data contents of the plot. The id is implementation-dependent, but first two variables x and y should be mapped to 0 and 1 correspondingly. Therefore every plot containting data must support getData(0). For invalid ids null is returned.

Overrides:

getData in class PGSCanvas
