@Api(allMethods=true)
public abstract class AbstractGraphicsController
extends org.geomajas.gwt.client.controller.AbstractController
implements GraphicsController

Abstraction of the GraphicsController that implements all methods as empty methods. By using this as a starting point for your own controllers, you don't have to clutter your code with empty methods that you don't use anyway.

What makes this class special is that it provides a few protected methods for easily acquiring information from the mouse events. You can for example get the event's position, or target DOM element.

Since:

1.6.0

getOffsetX

@Deprecated
public int getOffsetX()

Deprecated. Since 1.10, due to http://jira.geomajas.org/browse/GWT-354. No longer used.

An offset along the X-axis expressed in pixels for event coordinates. Used when controllers are placed on specific elements that have such an offset as compared to the origin of the map. Event from such elements have X,Y coordinates relative from their own position, but need this extra offset so that we can still calculate the correct screen and world position.

Specified by:

getOffsetX in interface GraphicsController

Since:

1.8.0

setOffsetX

@Deprecated
public void setOffsetX(int offsetX)

Deprecated. Since 1.10, due to http://jira.geomajas.org/browse/GWT-354. No longer used.

An offset along the X-axis expressed in pixels for event coordinates. Used when controllers are placed on specific elements that have such an offset as compared to the origin of the map. Event from such elements have X,Y coordinates relative from their own position, but need this extra offset so that we can still calculate the correct screen and world position.

Specified by:

setOffsetX in interface GraphicsController

Parameters:

offsetX - Set the actual offset value in pixels.
