i used to develope "The Eclipse Tabbed Properties View" article, he used a listViewer to list his controls,
but in my application, i want to use a treeViewer.
is there any Error in my "ViewContentProvider" and "ViewLabelProvider" ?
where the nodes i created for the tree is an object for the ButtonElement.
class ViewContentProvider implements IStructuredContentProvider, ITreeContentProvider {
public void inputChanged(Viewer v, Object oldInput, Object newInput) {
}
public void dispose() {
}
public Object[] getElements(Object parent) {
return getChildren(parent);
}
public Object getParent(Object child) {
if (child instanceof TreeObject) {
return ((TreeObject)child).getParent();
}
return null;
}
public Object[] getChildren(Object parent) {
if (parent instanceof TreeParent) {
return ((TreeParent)parent).getChildren();
}
return new Object[0];
}
public boolean hasChildren(Object parent) {
if (parent instanceof TreeParent)
return ((TreeParent)parent).hasChildren();
return false;
}
}
class ViewLabelProvider extends LabelProvider {
public String getText(Object obj) {
return obj.toString();
}
public Image getImage(Object obj) {
String imageKey = ISharedImages.IMG_OBJ_ELEMENT;
if (obj instanceof TreeParent)
imageKey = ISharedImages.IMG_OBJ_FOLDER;
return PlatformUI.getWorkbench().getSharedImages().getImage(imageKe y);
}
}
