I'm new in javafx... but the javafx language syntax seam to be many thing new... : )
And I got a problem... : |

package canvas;

Stage {
    title: "Application title"
    width: 500
    height: 500
    scene: Scene {
        var clickcount = 0;
        content:Group {
            content: for(i in [1..8], j in [1..8]){
                var zoom = 1;
                var recbig = 40;
                Rectangle {
                    x: i*recbig*zoom,
                    y: j*recbig*zoom
                    width: recbig*zoom,
                    height: recbig*zoom
                    fill: Color.BLACK
                    stroke:Color.WHITE
                    strokeWidth:1
                    onMouseEntered: function( e ):Void {
                        var rect: Rectangle = e.node as Rectangle;
                        rect.fill = Color.BLUE;
                    onMouseExited: function( e ):Void {
                        var rect: Rectangle = e.node as Rectangle;
                        rect.fill = Color.BLACK;
                    onMousePressed: function( e ):Void {
                        var rect: Rectangle = e.node as Rectangle;
                        rect.fill = Color.GREEN;
                        clickcount++;
                        //How can I get the rectangle index ...?
}*[Problem]*
I have:
1. int array [i..8,j..8]
2. rectangle array [i..8,j..8]
3. I have a rectangle array display in a window. Picture -> [http://www.onjava.com/onjava/2007/07/27/graphics/grill.gif]
4. I add mouse click event for each rectangle
*5*. Mine problem is "_How I get the index of the rectangle in the rectarray when I click on any display rectangle_"
Ex: I click on Rect[col:2,row:3] and I have the return value is col:2 & row:3.
So I can mark it on int array at col:2 & row:3
Thank for reading my problem... and thank a lot if have any answer... : )
And if you have any new best solution for this problem please share. : ) Thank much!!!

Answer 1

What do you mean "you can use those features of Java from JavaFX"?
I thought that JavaFX don't have a "true multi-dimensional arrays". Because I had tried a multi-dimensional arrays but it seam to be impossible.Correct. JavaFX doesn't have multi-dimensional arrays, and it also doesn't have a lot of the capabilities found in the Java Collections API. However, because JavaFX compiles to JVM bytecode, you can use Java functionality in your JavaFX program. For example, if you need a true multi-dimensional array, you could create a Java class that contains a multi-dimensional array and exposes getters and setters. On a related note, you could use the Collections API directly, as in the example in the following post (that also demonstrates reflection in JavaFX).
http://javafxpert.com/weblog/2009/03/answering-reader-mail-about-the-javafx-reflection-api.html
Note that the source code in that post imports java.util.Iterator, etc. to iterate over a Java collection. It also uses java.util.Date
A disadvantage of using these approaches is that JavaFX can't bind to POJOs (yet).
