Re: reuse of private static variable

Then, if I need to use one copy of the image a few times or the same widget a few places, then what should I do?

The DOM acts like a tree with each node having exactly one parent node (except the root node which has no parent).

Re: reuse of private static variable

Thanks a lot for your reply. Is there any technical name to describe this feature? I would like to google it to understand the detail.

Thanks

An element can only have one parent at a time in the DOM tree. If you add it somewhere, you (implicitly) first remove it from where it was.

By extension, this also applies to GWT widgets (which wrap a DOM element).

Hi

I have a class that contains static private variable. If the static private variable is access somewhere as shown in BiggerPanel, the SocialScreen flexTable.setWidget will not set an image as expected. No image is put in the flextable. The SocialScreen flexTable.setWidget works if I remove the SocialScreen.getfbImage() from BiggerPanel. It seems the static private variable is not reusable. Why is it like that?

Thanks

class SocialScreen extends composite
{
static private Image fbImage;

static public Image getFacebookImage()
{
        return fbImage;
}
public SocialScreen()
{
//To put the face book on the flextable
        fbImage = new Image(images. facebookIconImageData(). getSafeUri());
        image = fbImage;
        flexTableLeft.setWidget(r,c, image);
}

Class BiggerPanel
{
socialPanel=new SocialScreen();
acctPanel=new AcctPanel(){
    //Use the static function/static image of the SocialScreen
    Image fb=SocialScreen.getfbImage()
}
