Move PApplet (setLocation) doesn't work

in Integration and Hardware • 2 years ago

Hi guys,

I installed proclipsing ( http://code.google.com/p/proclipsing/wiki/GettingStarted) in eclipse to be able to use processing in eclipse. Everything worked fine but now I ecnounternd some problems:

I wanted to move the Applet Window with:

this.setLoaction(x,y) -> nothing happend
or
frame.setLocation(x,y)
-> NullPointerException:
Exception in thread "Animation Thread" java.lang.NullPointerException
    at Test.VideoTest.draw(VideoTest.java:19)
    at processing.core.PApplet.handleDraw(Unknown Source)
    at processing.core.PApplet.run(Unknown Source)
    at java.lang.Thread.run(Unknown Source)

I dont't have any idea why it doesn't work.

Also I wanted to open the browser with the method:

link(url)

but nothing happens too.

Has anyone an idea to solve this problem? Thank you :)

For the frame.setLocation() problem it depends of the renderer mode.
In OpenGL it works inside setup() in other renderers frame.setLocation() works inside draw().

See this thread and this one.

Thank you, no it works but unfortunately it doesn't make the effect I wanted.
So here is my code:

package Test;

import processing.core.PApplet;
import processing.video.Movie;

public class Test extends PApplet{
    public static void main(String args[]) {
        PApplet.main(new String[] { "--present", "Test.VideoTest" });
    }
    Movie myMovie;

    public void setup(){
        size(640,480,P2D);
        background(0);


    }

    public void draw(){
        setLocation(200,200);
    }
}

As you can see in the pic: It sets the location inside the window but I want to move to window to an other position on the screen.

Change

setLocation(200,200);

frame.setLocation(200, 200);

In order to move the window you need to move the frame which contain the applet.
That's why you need to call setLocation method on frame (which is a Frame object) and not on the applet itself.
If you call setLocation() you call this method from your Test object herited from PApplet itself herited from AWT applet.
Moving the applet location within the window but not the window.
