#24 setSystemCursorEnabled(false) problem

[Marco Perrone]

Hi Nicolas,
thanks a lots for your job, is great job.

I use jpen-2-150301, in my application i try to set wintabProvider.setSystemCursorEnabled(false);
but in this way the pen events are captures only if the mouse is on the component.

How we can solve it ?

In attach the sample.

Thanks in advice

hi Marco,

If you want to fully prevent the tablet from moving the cursor while changing the focus between various applications then I guess it won't be possible using jpen/wintab. For example, changing the active window (to another application) will cause the wintab context to change and this can cause the tablet device to begin changing the cursor position.

For the sake of testing or understanding this limitation of jpen/wintab you can try something like Test.java :

import jpen.event.PenListener;
import jpen.PButtonEvent;
import jpen.PenManager;
import jpen.PKindEvent;
import jpen.PLevelEvent;
import jpen.provider.wintab.WintabProvider;
import jpen.PScrollEvent;

public class Test
    implements PenListener{

    public static void main(String... args) throws Throwable{
        new Test();
    }

    Test() throws InterruptedException{
        PenManager pm=new PenManager(ActivableScreenPenOwner.getInstance());
        pm.pen.addListener(this);

        WintabProvider wintabProvider = pm.getProvider(WintabProvider.class);
        if(wintabProvider!=null)
            wintabProvider.setSystemCursorEnabled(false);

        while(true){
            System.out.println("--- reactivating...");
            ActivableScreenPenOwner.getInstance().reactivate();
            Thread.currentThread().sleep(5000);
        }
    }

    //@Override
    public void penButtonEvent(PButtonEvent ev) {
        System.out.println(ev);
    }
    //@Override
    public void penKindEvent(PKindEvent ev) {
        System.out.println(ev);
    }
    //@Override
    public void penLevelEvent(PLevelEvent ev) {
        System.out.println(ev);
    }
    //@Override
    public void penScrollEvent(PScrollEvent ev) {
        System.out.println(ev);
    }
    //@Override
    public void penTock(long availableMillis) {
        System.out.println("TOCK - available period fraction: "+availableMillis);
    }
}

The ActivableScreenPenOwner.java file is attached. You can run Test.main and try changing focus to other application windows while moving the mouse and the tablet device alternatively. Here is the thread where the previous code was introduced.

Cheers,
Nicolas
