Re: [platform-swt-dev] Working with different threads in SWT

["Roman Kournjaev" <kournjaev@xxxxxxxxx>]

Hi Tom

I am sorry for bothering you with my questions , but i simply don't understand where do i post the code , i got to this link 
http://dev.eclipse.org/newslists/news.eclipse.platform.swt/maillist.html , i searched a little through the site but there is not such options as post , or open theme. Regarding the question the thread spawning is done in the main thread , here is the runnable class , which is  launched asynchrony.


import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.graphics.Rectangle;
import org.eclipse.swt.widgets.Composite;

class Rotate implements Runnable
{
    private Image image;
    private Composite comp;

    public Rotate(Image image, Composite comp) {
        this.image = image;
        this.comp = comp;
    }
    public void run()
    {
        Rectangle rect = comp.getBounds();
        try{
            for (int i = 0 ; i <= rect.width / 2 ; i++)
            {
                comp.setBounds(rect.x + i, rect.y , rect.width - i*2 , rect.height);
                Thread.sleep(1);
                
            }
            for (int i = rect.width / 2 - 1 ; i >= 0  ; i--)
            {
                comp.setBounds(rect.x + i , rect.y , rect.width - i*2 , rect.height);
                Thread.sleep
(1);
            }
        }
        catch (InterruptedException e)
        {
            e.printStackTrace();
        }
        comp.setBackgroundImage(image);
    }

}

Sie konnen mir auch auf Deutsch antworten.
Vielen Dank im Vorraus!

Hi,

Please post the code you are running and the question to the
platform.swt newsgroup. I suppose you are doing all the thread spawing,
... in the runnable which is simply wrong. You should the only lines of
code you should run in the Runnable are the calls to the SWT-Functions.
