How to write a custom swing component




Java has matured over the years. It has been a decade and a half since its inception, and the language is still going strong and is keen on exploring newer technological paradigms and parlance. Since the coinage of the famed phrase "Write Once, Run Anywhere" how to write a custom swing component abbreviated to WORAthe language has broken all traditional programming barriers. Till date, there is no mainstream programming language that can compile code that runs everywhere.

In fact, all. NET programming languages owe their existence to the wonderful language that is Java. Although this article is written for extreme beginners in Java, it still requires the knowledge cell homework help the fundamentals of the language and a little understanding of how the Java Swing framework works.

Swing, basically, is a windowing framework that helps developers write code to create Windows essay writing for class desktop applications. Throughout this article, I will try my best to explain some of the design principles click here Swing as well.

Although the Swing framework has pretty much every UI component available at the developer's disposal, i. It turns cultural relativism essay that creating such how to write a custom swing component components in Swing is extremely easy to do.

And, once you start working your way around the initial confusion, you'll begin enjoying the experience. One of the main concerns that I had before writing this article was probably the fact that there was no decent article available on CodeProject that explained how to create a custom component in Swing. So, here goes. Every custom component built using the Swing framework has to follow some very important guidelines. The first of which is inheriting the javax.

JComponent class. Following is how you geometry connections help go about creating a custom component:. In a nutshell, the above code creates a custom component named FancyButtonwhich identifies itself as a component just by inheriting the javax.

You would not be able to run the code, however. The reasons being:. We have now set the stage for our experiments to begin. In the above code, we create a javax. Here we provide the title of the window as "Test Frame", appropriate enough for this tutorial. But, note one important thing: we haven't yet constructed our custom component, nor have we placed it on the frame yet.

Let's do that now. You'd surely be disappointed if you run the code now. That's because you'd see the same old JFrame as in the previous example and nothing much would have had changed. A reason for that would be that your component is not being painted on the screen. Let's fix how to write a custom swing component now. Plus, you how to write a custom swing component to note the growing imports at the beginning of the program code. We will also truncate the main String[] method for the sake of clarity, but you should include that in your program from the previous example.

Source time when you'll run the code, you'll note that the whole window frame would turn into a red colored how to write a custom swing component see the screenshot below.

Everything that turns red on the frame is the area bounds for our newly painted component. Painting on a component is enabled by overriding the paintComponent Graphics method in the JComponent class. Notice the explicit use of the Override annotation before the method declaration. This ensures that the method is properly overridden in the sub-class FancyButton. Because our component is spread across the entirety of the window frame, we witness the complete window frame as a block of red.

Within the body of the paintComponent Graphics method, we use the acquired java. Graphics objects to paint. The graphics. This is achieved using the graphics. Now, since we placed the component right in the center of the window frame, it takes up all the space on the frame, giving the illusion of the window frame turning red throughout. Now, before we start exploring the process of painting components, we need to learn a bit more about the java.

Graphics class. The Graphics class presents us with various methods to paint different shapes, line dissertation grants public administration and fonts on any component or container, thus enabling us to completely design a component from scratch. Hence, by overriding the paintComponent Graphics method on any component, we get the possibilities of designing an aesthetically appealing design for our components.

Some of the methods this class has to offer are as follows:. Spoiled with choice, we may choose any of these methods to paint pretty shapes to define the design and structure of our component. The difference between the shape fill and shape stroke methods is how to write a custom swing component simple. Shape fill methods fill the area of a certain shape with the color buffer the color we set with the setColor Color method of the Graphics class.

We will find use to almost all these methods over the course of further parts to this tutorial. For now, we would need to define what kind how to write a custom swing component component we'd like to create. Since, for the sake of this tutorial, we already named our component FancyButtonyou would already have guessed it would be something to do with being a button.

But, before we go any further, we need to define what we really want our button to do, or at least how we would want our button to look like. I call this process the Component Design Checklist. It might sound like a mundane task, but when it comes down to it, there's no better way than to keep tabs on your progress. The best place to start would be to create a simple checklist of do's and dont's.

This simple checklist would help us prioritize what needs to be done and what we should not care about. An initial attempt at creating a Component Design Checklist. This helps confine my creativity to a simple list of do's and dont's. The http://carrborocommons.org/writing-an-essay/dissertation-professor-killings.html include changing the color of the component from flashing red to a decent gray so it's easier on the eyes.

Instead of fillRect This simple effect gives the button a more pleasing and rounded look. Plus, I managed to add a 2px border around the component by changing the values within the fillRoundRect This would help me to later visualize the border settings that I mentioned in my checklist.

If you look at the screenshot below, you'll immediately notice the difference. Dissertation study groups screenshot displays the amends made to the initial code after implementing a few of the actions in my Component Design Checklist.

But soon afterwards, you begin to see some new and immediate problems emerge. One such problem is the dithering of the rounded corners. That should be easy to fix. More than that, this problem goes directly onto my checklist as: Enable anti-alias rendering.

In revisions to follow, we will look at how we solve these individual problems to create an aesthetically pleasing custom UI component for Swing. Stay tuned for more. Copy Code.
