| RE: [gef-dev] TreeViewer root element |
I had the same problem. I resolve it creating a TreeEditPart class for my root and then overriding the setWidget method :
public class MyRootTreeEditPart extends TreeEditPart {
/* (non-Javadoc)
* @see org.eclipse.gef.TreeEditPart#setWidget(org.eclipse.swt.widgets.Widget)
*/
public void setWidget(Widget widget) {
if (widget instanceof Tree) {
TreeItem item = new TreeItem((Tree) widget, SWT.MULTI); // create the treeitem for the root
widget = item;
}
super.setWidget(widget);
}
}
Image and text are not set here, you have to override getImage() and getText().

Objet : [gef-dev] TreeViewer root element
Hello gef-dev,
Why TreeViewer doesn't show root element of my model?
Example:
model has structure
my model root element
|
+- my model child element 1
+- my model child element 2
After call to TreeViewer.setContent(my model root element) actually
on screen I see only child elements.

Best regards,
