Example 1 with Disposable

use of org.springsource.ide.eclipse.commons.livexp.ui.Disposable in project eclipse-integration-commons by spring-projects.

the class SwtConnect method connectTextBasedFilter.

/**
 * Connect a filterbox model to a treeviewer. This assumes that the filter is text-based. The filter is applied to the labels of the elements in the tree.
 * <p>
 * For the viewer filter to work correctly the ITreeContentProvider must provide a proper implementation of the 'getParent' method. If getParent only
 * returns null the viewer filter will not be able to check whether an element should be shown when a parent element is selected by the search filter.
 * <p>
 * Note: you can use {@link TreeElementWrappingContentProvider} in order to ensure that ITreeContentProvider keeps track of parent nodes properly.
