the class NlComponentUtils method getTopMostInChain.

public static NlComponent getTopMostInChain(NlComponent component) {
    HashMap<String, NlComponent> map = getMap(component);

Example 3 with NlComponent

use of com.android.tools.idea.uibuilder.model.NlComponent in project android by JetBrains.

the class ConstraintLayoutHandler method willDelete.

/**
   * Update the given component if one of its constraint points to one of the component deleted
   *
   * @param component the component we want to check
   * @param deleted the list of components that are deleted
   */
private void willDelete(NlComponent component, @NotNull List<NlComponent> deleted) {
    final int count = deleted.size();
    for (int i = 0; i < count; i++) {
        NlComponent deletedComponent = deleted.get(i);
        String id = deletedComponent.getId();
        ConstraintComponentUtilities.updateOnDelete(component, id);
    }
}

Example 4 with NlComponent

use of com.android.tools.idea.uibuilder.model.NlComponent in project android by JetBrains.

the class ConstraintLayoutHandler method deleteChildren.

/**
   * Called when one or more children are about to be deleted by the user.
   *
   * @param parent  the parent of the deleted children (which still contains
   *                the children since this method is called before the deletion
   *                is performed)
   * @param deleted a nonempty list of children about to be deleted
   * @return true if the children have been fully deleted by this participant; false if normal deletion should resume. Note that even though
   * an implementation may return false from this method, that does not mean it did not perform any work. For example, a RelativeLayout
   * handler could remove constraints pointing to now deleted components, but leave the overall deletion of the elements to the core
   * designer.
   */
@Override
public boolean deleteChildren(@NotNull NlComponent parent, @NotNull List<NlComponent> deleted) {
    final int count = parent.getChildCount();

            continue;
