TWaver With JavaFX
JavaFX Script被抛弃以后，很久不关心JavaFX了，偶然发现JavaFX已经发展到2.2，而且已经绑定到JDK7中，看来Oracle对它还是蛮重视的。
看到有人在论坛提问TWaver有没有JavaFX版本，于是去Oracle网站上逛了一下，发现可以将JavaFX集成进Swing程序中，真是福音啊，立马动手写了个Demo，集成起来还是很方便的。
运行效果
代码分析
窗体中间是个很典型的Network，上下各是一个JavaFX容器，上面容器中包含一个Slider，滑动时可以改变TWaver选中Node的RenderColor，下面的容器中包含一些Text，选中Network中的Node并拖动的时候在Text组件上显示Node的name和location。
在这个Demo里，程序架构还是Swing，JavaFX提供了一个名为JFXPanel的组件可以嵌入到Swing容器中，JFXPanel内可以放JavaFX的组件，需要注意，Swing和JavaFX的线程不同，官方的原文是："JavaFX data should be accessed only on the JavaFX User thread","Swing data should be changed only on the EDT"，所以如果要在Swing中修改JavaFX的数据，应该使用Platform#runLater包装，本例中，拖动Node时修改JavaFX的Text组件的相关代码：
network.getDataBox().addElementPropertyChangeListener(new PropertyChangeListener() {
@Override
public void propertyChange(PropertyChangeEvent evt) {
if("location".equals(evt.getPropertyName())){
Element element= (Element) evt.getSource();
final String name=element.getName();
final double x=element.getX();
final double y=element.getY();
Platform.runLater(new Runnable() {
@Override
public void run() {
nameText.setText(name);
locationText.setText("X:"+x+" Y:"+y);
}
});
}
}
});
同样，如果要在JavaFX中修改Swing数据，也要用SwingUtilities#invokeLater包装，本例中，滑动Slider修改选中Node的Render Color代码如下：
slider.valueProperty().addListener(new ChangeListener<Number>() {
public void changed(ObservableValue<? extends Number> ov,
Number old_val,final Number new_val) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
Iterator it=network.getSelectionModel().selection();
while (it.hasNext()){
Element element= (Element) it.next();
element.putRenderColor(new java.awt.Color(new_val.intValue()));
}
}
});
}
});
最后附上全部代码：
public class Test1 {
static TNetwork network;
static Text nameText;
static Text locationText;
static Slider slider;
private static void initAndShowGUI() {
initNetwork();
JFrame frame = new JFrame("TWaver With JavaFX");
frame.getContentPane().setLayout(new BorderLayout());
frame.setSize(500, 300);
frame.setVisible(true);
frame.getContentPane().add(network);
final JFXPanel controlFXPanel = new JFXPanel();
frame.add(controlFXPanel,BorderLayout.NORTH);
final JFXPanel statusFXPanel = new JFXPanel();
frame.add(statusFXPanel,BorderLayout.SOUTH);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
network.getDataBox().addElementPropertyChangeListener(new PropertyChangeListener() {
@Override
public void propertyChange(PropertyChangeEvent evt) {
if("location".equals(evt.getPropertyName())){
Element element= (Element) evt.getSource();
final String name=element.getName();
final double x=element.getX();
final double y=element.getY();
Platform.runLater(new Runnable() {
@Override
public void run() {
nameText.setText(name);
locationText.setText("X:"+x+" Y:"+y);
}
});
}
}
});
