Example 1 with ViewGraphModel

use of easik.view.util.graph.ViewGraphModel in project fql by CategoricalData.

the class View method removeNode.

/**
 * Removes an entity, and also cascades to remove all the arrows involved
 * with it.
 *
 * @param toRemove
 *            The entity about to be removed
 */
@Override
public void removeNode(final QueryNode toRemove) {
    // So we don't get a ConcurrentModificationException

        if (edge.getSourceQueryNode().equals(toRemove) || edge.getTargetQueryNode().equals(toRemove)) {

            removeEdges.add(edge);

    // Remove the edges

    for (ModelConstraint<ViewFrame, ViewGraphModel, View, QueryNode, View_Edge> c : toRemove.getConstraints()) {

    getGraphLayoutCache().remove(new Object[] { toRemove });
    // Remove Entity from tree
    _Frame.getInfoTreeUI().removeNode(toRemove);
    model.endUpdate();
}

Example 2 with ViewGraphModel

use of easik.view.util.graph.ViewGraphModel in project fql by CategoricalData.

the class View method initialiseModel.

/**
 * When we initialize the sketch, we flush out all the data concerning the
 * sketch itself. Even the modelAdapter is reinitialized.
 *
 * This methods serves as a "new sketch" function.
 */
@Override
public void initialiseModel() {
    clearSelection();
    model = new ViewGraphModel(this);
    final GraphLayoutCache glc = new GraphLayoutCache(model, new ModelViewFactory<ViewFrame, ViewGraphModel, View, QueryNode, View_Edge>());
    setModel(model);
    setGraphLayoutCache(glc);
    _nodes = new LinkedHashMap<>();
    _edges = new LinkedHashMap<>();
    if (_Frame.getInfoTreeUI() != null) {
        // Wipe
        _Frame.setInfoTreeUI(new ModelInfoTreeUI<>(_Frame));
        // Tree
