Parallax scrolling uses multiple objects at different speeds to give the impression of a 3d effect where nearby objects have a larger parallax than more distant objects when observed from different positions. If you're looking for a popular scrolling effect used by native mobile apps and amazing websites, download the vertical parallax.

The Vertical Parallax Animation component is a single-page animated UI with a background image and a foreground flex. The component helps you create a parallax animation effect in an application that improves the user experience.

Here is a use case that describes the use of the Vertical Parallax Animation component.

Component Functionality

The following screen shot describes on how the component looks.

flxBackground and flxForeground are the target containers where user can drag any widget / components. For more details on Target Container click here.

Use Case

Consider a case that you are developing an app that provides information about monuments. You can add the Vertical Parallax Animation in the app and configure the component in such a manner that the app displays the image of a monument in the background and related information in the foreground.

The Vertical Parallax Animation component is a ready-to-use component. You can import the Vertical Parallax Animation component into your app (created in Kony Visualizer) and achieve the features of parallax animation in vertical manner. The Vertical Parallax Animation component also facilitates a set of properties that helps you customize the background and the foreground as you require.

The following sections help you use the Vertical Parallax Animation component in your app.

Prerequisites

Before you start using the Vertical Parallax Animation component, ensure you have the following:

  1. Kony account
  2. Kony Visualizer Enterprise V8

Importing the Vertical Parallax Animation Component

Before you start importing the component to Kony Visualizer, you must download the component from the Kony Marketplace website.

To import the Vertical Parallax Animation component, do the following:

  1. Open your app project in Kony Visualizer.
  2. On the File menu, point to Import, and click Component. The Open dialog appears.
  3. Navigate to the location where you downloaded the component (zip file) on your computer, select the component, and click Open. The Import Marketplace Item dialog appears.

  4. In the Library Name box, type a name if you want to create a new library. Otherwise, you can select the existing library name.
  5. In the Collection Name box, type a name if you want to create a new collection. Otherwise, you can select the existing collection name.
  6. In the Component Name box, the com.konymp.verticalparallax name is displayed by default.

When you import a component, the component is imported to Visualizer's workspace, but not directly into your app. Thus, after you import a component, you must add the component to your app.

Adding a Vertical Parallax Animation Component to your App

You can add a Vertical Parallax Animation component to FlexForms, FlexContainer, and FlexScrollContainer widgets.

To add a Vertical Parallax Animation component:

  1. Open your app, and then open the form to which you want to add the component.
  2. On the My Libraries tab, select the defined Marketplace library from the drop-down list in which the component exists.

  3. From the Collections sub-tab, drag the component onto the form on the Visualizer canvas. The component is added to the form.
    You can also see a new element, com.konymp.verticalparallax in the Components section on the Templates tab.
Note:

Ensure that the component is set to occupy 100 percent width of the device. You can achieve this by setting the width of the parent widget to 100 percent.

After adding a component to a form, you can configure the component the way you want it using the Look, Skin, and Action tabs on the Properties pane. Configuring the properties on the Properties pane is similar to configuring the properties of any widget in Kony Visualizer. For more information, refer Button Widget.

You can also see that a new tab, Component, is added on the Properties pane. The Component tab contains assorted properties relevant to the component that allow you to customize the component as required.

You can also add a Vertical Parallax Animation Component dynamically. To do so,

  1. In the Project Explorer, on the Projects tab, click Controllers section to access the respective formController. Create a method and implement the code snippet similar to the sample code mentioned below.
/* creating a component's Object */
var verticalparallax = new com.konymp.verticalparallax({
		"clipBounds": true,
		"height": "100%",
		"id": "verticalparallax",
		"isVisible": true,
		"layoutType": kony.flex.FREE_FORM,
		"left": "0dp",
		"masterType": constants.MASTER_TYPE_USERWIDGET,
		"skin": "konympSknFlxbackground",
		"top": "0dp",
		"width": "100%"
		}, {}, {});

/* Setting the component's properties */
      verticalparallax.parallaxSpeed = 5;
      verticalparallax.isBgPlaceholderVisible = true;
      verticalparallax.isFgPlaceholderVisible = true;
      vverticalparallax.isImgDetailsVisible = true;
      
/*Adding the Vertical Parallax component to a Form*/
            this.view.add(verticalparallax); 

In the code snippet, you can edit the properties of the component as per your requirement. For more information, see Properties.

Save the file.
