Restrict panning to the boundaries of my Network or Equipment component

Question

How to restrict panning to the boundaries of my Network or Equipment component?

Answer

JTGO uses IlvPanInteractor to pan the view. To prevent the mouse dragging from going outside the boundaries of the container, you can override the method IlvPanInteractor.processMouseMotionEvent. For example:

class MyPanInteractor extends ilog.views.interactor.IlvPanInteractor

{

protected void processMouseMotionEvent(java.awt.event.MouseEvent e) {

int dx = 0;

int dy = 0;

if (e.getX() >= 0)

dx = Math.min(0, getManagerView().getWidth() - e.getX());

else

dx = -e.getX();

if (e.getY() >= 0)

dy = Math.min(0, getManagerView().getHeight() - e.getY());

else

dy = -e.getY();

e.translatePoint(dx, dy);

super.processMouseMotionEvent(e);

}

}
