Example 1 with Index

use of org.openide.nodes.Index in project ACS by ACS-Community.

the class MoveUpActionCopiedFromNetbeans method enable.

/* Manages enable - disable logic of this action */
protected boolean enable(Node[] activatedNodes) {
    initErr();
    if (err != null) {
        err.log(ErrorManager.UNKNOWN, "enable; activatedNodes=" + (activatedNodes == null ? null : Arrays.asList(activatedNodes)));

Example 2 with Index

use of org.openide.nodes.Index in project ACS by ACS-Community.

the class MoveDownActionCopiedFromNetbeans method performAction.

    * in the order.
    * @param activatedNodes The nodes on which to perform the action.
    */
protected void performAction(Node[] activatedNodes) {
    // we need to check activatedNodes, because there's no
    // guarantee that they not changed between enable() and
    // performAction calls
