the class ProfileAvatarsTitleComponent method createAvatar.

    // We will then handle the clicks and long presses ourselves, because
    // we may need to expand the list of avatars and allow the user to
    // choose an avatar from the list.

Example 3 with ViewNode

use of com.codename1.rad.nodes.ViewNode in project CodeRAD by shannah.

the class Controller method createViewNode.

/**
 * Creates the view node that should be used as the node for the controller's view. This method should
 * be overridden by subclasses to define the default view node, but this method shouldn't be called directly.  Rather
 * the {@link #getViewNode()} method should be called so that the view node is only created once.  {@link #getViewNode() }
 * will also set the parent node to the view node of the parent controller to more easily benefit from inherited attributes
 * in the UI descriptor hierarchy.
 * @return A ViewNode
