Method Detail

addCoordManagerListener

public void addCoordManagerListener(CoordManagerListener coordManagerListener)

Adds a coord listener to this coord manager.

Parameters:

coordManagerListener - listener of the coordinate changes.

updateRelativeCoords

public void updateRelativeCoords(CoordManageable coordProvider)

This method should be called when the size of the coordinate provider (a drawing area) changes and relative coordinates have to be recalculated.

Parameters:

coordProvider - drawing area that implements the CoordmManageable interface.

d

public int d(int position)

Parameters:

position - the value of the relative coordinate.

Returns:

the value of the absolute coordinate.

d

public int d(float position)

Converts relative coordinates to absolute. Suits for both x and y coords. Floating version, doesn't take into account origin and shift values.

Parameters:

position - the value of the relative coordinate.

Returns:

the value of the absolute coordinate.

d

public double d(double position)

Converts relative coordinates to absolute. Suits for both x and y coords. Double version, doesn't take into account origin and shift values.

Parameters:

position - the value of the relative coordinate.

Returns:

the value of the absolute coordinate.

_dx
