DragElement Class
Contrary to hearsay, the DragElement is <strong>NOT</strong> a male Element dressed in women’s clothing. It simply provides an easy-to-use Element pre-configured for managing Drag & Drop interaction, with a few extra features.
The DragElement class uses the single constructor of the Element class and configures the Element to:
Element.setIsDragDropDragElement(true);
Element.setIsMovable(true);It also provides a way of managing multiple drop elements and reacting to the appropriately.
Managing Drop Elements
// Add an element as a valid drop Element
dragEl.addDropElement(Element element);
// Retrieve an element(s)
dragEl.getDropElements(); // Return all drop elements
dragEl.getDropElement(int index); // Returns a single drop element by index
// Remove drop elements
dragEl.removeDropElement(int index);
dragEl.removeDropElement(Element element);Responding to Incorrect Drops
// Enable/disable springback (returns drag element to original position)
dragEl.setUseSpringBack(boolean useSpringBack);
dragEl.getUseSpringBack();
// Use SlideTo effect when springback is called
dragEl.setUseSpringBackEffect(boolean useSpringBackEffect);
dragEl.getUseSpringBackEffect();Responding to Correct Drops
//Position the DragElement in the center of drop element
dragEl.setUseLockToDropElementCenter(boolean lockToDropElementCenter);
dragEl.getUseLockToDropElementCenter();
// Use SlideTo effect when centering
dragEl.setUseLockToDropElementEffect(boolean useLockToDropElementEffect);
dragEl.getUseLockToDropElementEffect();
