I think the class WizardExportResourcesPage would be more useful if
subclasses could filter the elements shown in the tree and in the list.
Currently this class shows even hidden folders something that in my opinion
most of the times should not be presented to the user.

I propose something like this:

In WizardExportResourcesPage.createResourcesGroup(Composite parent) :
...
this.resourceGroup = new ResourceTreeAndListGroup(parent, input,        
getResourceProvider(getTreeResourceFilter()),
WorkbenchLabelProvider.getDecoratingWorkbenchLabelProvider(),
getResourceProvider(getListResourceFilter()), 
WorkbenchLabelProvider.getDecoratingWorkbenchLabelProvider(), SWT.NONE,
DialogUtil.inRegularFontMode(parent));
...

protected ITreeContentProvider getResourceProvider(final IResourceFilter
filter) {
...
for (int i = 0; i < members.length; i++) {
        if(filter.isSelectable(members[i])){
                results.add(members[i]);
        }
}
...

protected IResourceFilter getTreeResourceFilter(){
...
}

protected IResourceFilter getListResourceFilter() {
...
}

public interface IResourceFilter{
        boolean isSelectable(IResource resource);
}
