Javafx Graphics Animations And Applications

You can use JavaFX to quickly develop applications with rich user experiences. In this Getting Started tutorial, you will learn to create animated objects and attain complex effects with very little coding.

The tool used in this Getting Started tutorial is NetBeans IDE. Before you begin, ensure that the version of NetBeans IDE that you are using supports JavaFX 8. See the Certified System Configurations section of the Java SE Downloads page for details.

For the ColorfulCircles application, it is appropriate to use a group node as the root node for the scene. The size of the group is dictated by the size of the nodes within it. For most applications, however, you want the nodes to track the size of the scene and change when the stage is resized. In that case, you use a resizable layout node as the root, as described in Creating a Form in JavaFX.

Figure 7-3 shows the application. Because the code does not yet specify a unique location for each circle, the circles are drawn on top of one another, with the upper left-hand corner of the window as the center point for the circles. The opacity of the overlaid circles interacts with the black background, producing the gray color of the circles.

Continue by applying a box blur effect to the circles so that they appear slightly out of focus. The code is in Example 7-3. Add this code before the

. The rectangle is the same width and height as the scene and is filled with a linear gradient that starts in the lower left-hand corner (0, 1) and ends in the upper right-hand corner (1, 0). The value of

The next two lines of code make the linear gradient adjust as the size of the scene changes by binding the width and height of the rectangle to the width and height of the scene. See Using JavaFX Properties and Bindings for more information on binding.

An overlay blend is a common effect in graphic design applications. Such a blend can darken an image or add highlights or both, depending on the colors in the blend. In this case, the linear gradient rectangle is used as the overlay. The black rectangle serves to keep the background dark, while the nearly transparent circles pick up colors from the gradient, but are also darkened.

Figure 7-7 shows the results. You will see the full effect of the overlay blend when you animate the circles in the next step.

Javafx Application Structure

Figure 5-8 shows the 30 colorful circles in motion, which completes the application. For the complete source code, see the ColorfulCircles.java file.In JavaFX, by altering the property by time, animation can be done to a particular node. For this, a package javafx.animation is provided by JavaFX. It consists of classes that help in animating the nodes. For all these classes, the animation is considered the base class. There are different animations like Fill Transition, Scale Transition, Fade Transition, Stroke Transition, Rotate Transition, Sequential Transition, etc in this. In this article, we will see more in animation.

First, import all the necessary packages. Then, create a hexagon and add coordinates to the created hexagon. After this, fill color for the created hexagon. Moreover, set the node, angle, and cycle count also for the rotate transition created. Then, set false as the auto-reverse value and start playing the animation using the play() method. Next is to create a Group object and a scene object. Also, set the title for the created stage and add a scene to it. After this, display the contents of the stage st using the method show().

On executing the code, it can be seen that a hexagon of yellow color is rotating 360 degrees. This rotation will be for around 2000 seconds. The screenshots provided are taken two times for showing that the hexagon is rotating.

Using Javafx In A Netbeans Application

In JavaFX, the package “javafx.animation” is utilized to incorporate animation functionality. This package includes classes that assist in animating nodes within a JavaFX application. It offers various types of animations, such as Fill Transition and Scale Transition, which can be utilized to create dynamic visual effects.
