Example 1 with ITextInputListener

use of org.eclipse.jface.text.ITextInputListener in project xtext-eclipse by eclipse.

the class OutlinePage method configureTextInputListener.

/**
 * @since 2.0

protected void configureTextInputListener() {
    textInputListener = new ITextInputListener() {

        @Override
        public void inputDocumentChanged(IDocument oldInput, IDocument newInput) {

                if (xtextDocument != null && modelListener != null)
                    xtextDocument.removeModelListener(modelListener);

                    xtextDocument.addModelListener(modelListener);
                    scheduleRefresh();
                }
            } catch (Throwable t) {
                LOG.error("Error refreshing outline", t);
            }
        }

        @Override
        public void inputDocumentAboutToBeChanged(IDocument oldInput, IDocument newInput) {
        }
    };
    sourceViewer.addTextInputListener(textInputListener);
}

Example 2 with ITextInputListener

use of org.eclipse.jface.text.ITextInputListener in project eclipse.platform.text by eclipse.

the class AnnotationPainter method addAnnotationType.

/**
 * Adds the given annotation type to the list of annotation types whose annotations should be
 * painted by this painter using the given strategy. If the annotation type is already in this
 * list, the old strategy gets replaced.
 *
 * @param annotationType the annotation type
 * @param strategyID the id of the drawing or text style strategy that should be used for this
 *            annotation type
 * @since 3.0
 */
public void addAnnotationType(Object annotationType, Object strategyID) {
    fAnnotationType2PaintingStrategyId.put(annotationType, strategyID);
    fCachedAnnotationType2PaintingStrategy.clear();
    if (fTextInputListener == null) {
        fTextInputListener = new ITextInputListener() {
