Examples with NodeList elemental.dom.NodeList used on opensource projects

Example 1 with NodeList

use of elemental.dom.NodeList in project che by eclipse.

the class Tree method rightArrowPressed.

/**
     * Handles pressing the Right arrow button.
     * Does nothing when user selected a file. Expands a folder if the user has selected one.
     * Selects the first child if the folder is already selected and expanded.
     */
