How to add bold to the text that found in PatternFilter

I created TreeViewer and PatternFilter

PatternFilter patternFilter = new PatternFilter();
FilteredTree filter = new FilteredTree(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL, patternFilter, true);
treeViewer = filter.getViewer();

treeViewer.setContentProvider(new TreeContentProvider());
treeViewer.setLabelProvider(new TreeLabelProvider());
treeViewer.setAutoExpandLevel(AbstractTreeViewer.ALL_LEVELS);
treeViewer.setInput(Activator.getDefault().getTreeModel());

Tree tree = treeViewer.getTree();

How can I add bold text to the text results of the filter?

Like the filter in the preferences dialog in Eclipse

The Eclipse Preferences uses that same FilteredTree. Knowing this, it's easy from here.

A quick trip to FilteredTree, and CTRL + F the text bold.

First result is this method:

/**
 * Return a bold font if the given element matches the given pattern.
 * Clients can opt to call this method from a Viewer's label provider to get
 * a bold font for which to highlight the given element in the tree.
 * 
 * @param element
 *            element for which a match should be determined
 * @param tree
 *            FilteredTree in which the element resides
 * @param filter
 *            PatternFilter which determines a match
 * 
 * @return bold font
 */
public static Font getBoldFont(Object element, FilteredTree tree, PatternFilter filter)

If we search for where it's used, we find org.eclipse.ui.internal.dialogs.PreferenceBoldLabelProvider.

Use the same trick in your label provider.

Edit 1: As greg-449 said, I hope you're experienced enough to know not to use internal classes, rather immitate them and create your own by extending LabelProvider (in this case).
