In order to show how to pass a function to another funtion i adopted the reduce() function found in Effective Java: function reduce(seq: Integer[], f: function(: Integer, : Integer): Integer, init: Integer) { var result = init; for (i ...
Following is a code fragment. I am updating a rectangle using a for loop when a button is pressed. This is a model for my ultimate intention of showing visualization of data model as it changes large number of times inside a for loop. It works but I see only one change.

In JavaFx i can easy create animations, moving pieces etc., but as far as i see there is better to write program logic and communication in java. Worst i see at the moment is calling javafx part as a result of data incoming from server. Is there any convenient way to do it or its better to change to other technology (flex, qt?) assuming ...
Hi I am using a very simple JavaFx client to upload files. I read the file in chunks of 1 MB (using Byte Buffer) and upload using multi part POST to a PHP script. I want to update the progress bar of my client to show progress after each chunk is uploaded. The calculations for upload progress look correct but the progress bar is not up...
Is that possible?? I mean, I have an already working project that runs in windows mobile using the J9 virtual machine for CDC. My user interface there is using AWT and it works fine and it looks OK, but been honest it doesn't take real advantage of the devices were is running... So I start reading about JavaFX and that looks really cool...
I need a way to have a gray scale image in an ImageView and on mouse moved if the cursor position is in the ImageView bounds to show a colored spotlight on the mouse position. I have created a sample to help you understand what I need. This sample negates the colors of a colored image on the onMouseMoved event. package javafxapplicati...
I've coded small JavaFX Applet in Netbeans 6.8 IDE. Everything works fine if the applet runs on my computer. But when I put the applet (and edited JNLP files containing changed paths to server) into server, it doesn't load any data from an server text file. Paths are correct - i look at it many times - they are ok. It also doesn't load i...

Hi All. Im in the verge of starting a new RIA development. We've been using Flex/Flash for the last 2 years but we were considering using a more OS approach so we though giving JavaFX a try since it seams the only solid option available. However after a couple of days of research we found out that there is not such thing as a datagrid f...
I just solved the first problem from Project Euler in JavaFX for the fun of it and wondered what block expressions are actually good for? Why are they superior to functions? Is it the because of the narrowed scope? Less to write? Performance? Here's the Euler example. I used a block here but I don't know if it actually makes sense // s...
In Java, you sometimes do something like this: for (int a = 1, b = 2; b < high;) { if (b % 2 == 0) { result += b; } int tmp = b; b = a + b; a = tmp; } Here, I used a for loop instead of a while loop to limit the scope of a and b. But how can I achieve this in JavaFX? The for loop doesn't seem ...
