How to use

setHandler

method

in

go.graphics.event.mouse.GODrawEvent

private void handleDrawOnMap(GODrawEvent drawEvent) {
  this.currentSelectionAreaStart = drawEvent.getDrawPosition();
  updateSelectionArea = true;
  drawEvent.setHandler(this.drawSelectionHandler);
}

@Override
public boolean handleDrawEvent(GODrawEvent event) {
  if (context != null) {
    event.setHandler(new GOEventHandlerImplementation(event.getDrawPosition()));
  }
  return true;
}

@Override
public boolean handleDrawEvent(GODrawEvent event) {
  if (!containsPoint(event.getDrawPosition())) {
    return false;
  }
  Action action = getActionForDraw(event);
  if (action != null && context != null && minimap != null) {
    float y = context.getScreen().getHeight() / 2;
    float x = context.getScreen().getWidth() / 2;
    startMapPosition = context.getPositionOnScreen(x, y);
    event.setHandler(new DrawMinimapHandler());
    return true;
  } else {
    return false;
  }
