Javafx Developer Tips and Hacks.

I have been a java software developer for about three years now.About a year ago i have been using javafx to develop software applications.The amazing thing about javafx it embraces the philosophy in which Java was built upon,which is WORA(write once,run anywhere)this means java can run on any platform and system architecure.Using Javafx you can write amazing software applications for a variety of platforms mobile included; this has been made possible by the Java developer community.The code snippets am going to post on this blog are just but a few tips that may appear confusing to newbies.You can run and test them.If you want to use them in a production environment you notice you will have to optimize the code.You can do that or contact me so that i can optimize the code for you.For questions or interactions mail me at:kelvinkagia@gmail.com.Thanks in advance.
