如何声明JOGL Newt MouseEvent？

Question

I am currently using JOGL the OpenGL Java port and I need to use the com.jogamp.newt.event.MouseEvent

I don't know how to declare it, I found this documentation about it but I am still confused as to how I declare it

When I just did

public MouseEvent mouseEvent;

and tried to use mouseEvent.getX()

It returned a null pointer exception, I then tried

public MouseEvent mouseEvent = new MouseEvent();

But that needs some values inside the parenthesis which is what I am confused about

Answer 1

Unless you know exactly what you are doing, don't create a MouseEvent yourself.

Rather, you need to have a class implementing the jogamp MouseListener and add that to your GLWindow , like I am doing here for example

Then override the following methods:

@Override
public void mouseClicked(MouseEvent e) {    }

@Override
public void mouseEntered(MouseEvent e) {    }

@Override
public void mouseExited(MouseEvent e) {    }

@Override
public void mousePressed(MouseEvent e) {    }

@Override
public void mouseReleased(MouseEvent e) {    }

@Override
public void mouseMoved(MouseEvent e) {    }

@Override
public void mouseDragged(MouseEvent e) {    }

@Override
public void mouseWheelMoved(MouseEvent e) {    }

And you are good to go
