下面这两个类的含义是当用户假设打开5个窗口（包含图像的框架），然后用户单击第二个框架并想要关于该图像的信息时我能得到这些帧信息吗？在我之前的问题中，有人建议做单态枚举，我有点理解它并实现，但我不能包装我的头，当用户点击内部框架时，经理类将发送路径到Info类。保持跟踪窗口及其信息
我前面的问题：How to keep track of previous opened internal frames
这是Manager类：
public class Manager implements ActionListener{
private static int openFrameCount =0;
ImagePlus image;
private static String title;
final String SHOW ="show";
static ImageWindow m;
static JMenuItem showInfo;
static JMenuItem save;
static JDesktopPane desktop;
InfoGui in;
JMenuItem fft;
public Manager(ImagePlus img, String title, JDesktopPane desktop, JMenuItem save, JMenuItem fft, JMenuItem showInfo2){
image = img;
this.desktop = desktop;
this.title = title;
this.save = save;
this.fft = fft;
this.showInfo= showInfo;
}
public enum WindowManager implements InternalFrameListener, ComponentListener {
INSTANCE;
public MyInternalFrame frame;
private Map<ImagePlus, List<MyInternalFrame>> mapWindows;
private WindowManager(){
mapWindows = new HashMap<>(25);
}
public class MyInternalFrame extends JInternalFrame {
static final int xPosition = 30, yPosition = 30;
public MyInternalFrame(String title, ImagePlus img, JMenuItem save) {
super(title, true,true, true, true);
setSize(img.getWidth(),img.getHeight());
// Set the window's location.
setLocation(xPosition * openFrameCount, yPosition * openFrameCount);
save.setEnabled(true);
}
}
public JInternalFrame createWindowFor(ImagePlus image) {
List<MyInternalFrame> frames = mapWindows.get(image);
if (frames == null) {
frames = new ArrayList<>(25);
mapWindows.put(image, frames);
}
JPanel panel = new JPanel();
ImageCanvas c = new ImageCanvas(image);
c.getImage();
//panel2.add(new JLabel(new ImageIcon(c.getImage())));
m = new ImageWindow(image);
Image n = new Image();
//frame = new MyInternalFrame(title, img, save,m);
//ImageCanvas c = m.getCanvas();
ImagePlus im = new ImagePlus();
im.setImage(image);
frame = new MyInternalFrame(image.getTitle(), image, save);
m.centerNextImage();
image.getCanvas().setScaleToFit(true);
panel.add(m.getCanvas());
panel.setBackground(Color.white);
frame.add(panel);
frames.add(frame);
frame.setVisible(true);
frame.setAutoscrolls(true);
frame.setAutoscrolls(true);
frame.setOpaque(true);
desktop.add(frame);
try {
frame.setSelected(true);
} catch (java.beans.PropertyVetoException e) {
}
frame.addInternalFrameListener(this);
frame.addComponentListener(this);
return frame;
}
public List<MyInternalFrame> getImage() {
JInternalFrame frame = null;
return mapWindows.get(title);
}

}
这是我的信息类：
public class Info implements ActionListener{
private static int openFrameCount =0;
ImagePlus image;
private static String title;
final String SHOW ="show";
static ImageWindow m;
JMenuItem showInfo;
static JMenuItem save;
static JDesktopPane desktop;
InfoGui in;

public Info(ImagePlus img, String title, JDesktopPane desktop, JMenuItem save, JMenu fft){
image = img;
this.desktop = desktop;
this.title = title;
this.save = save;
this.fft = fft;
}
public enum WindowManager implements InternalFrameListener, ComponentListener {
INSTANCE;
public MyInternalFrame frame;
private Map<ImagePlus, List<MyInternalFrame>> mapWindows;
private WindowManager(){
mapWindows = new HashMap<>(25);
}
public class MyInternalFrame extends JInternalFrame {
static final int xPosition = 30, yPosition = 30;
public MyInternalFrame(String title, ImagePlus img, JMenuItem save) {
super(title, true,true, true, true);
setSize(img.getWidth(),img.getHeight());
// Set the window's location.
setLocation(xPosition * openFrameCount, yPosition * openFrameCount);
save.setEnabled(true);
}
}
public JInternalFrame createWindowFor(ImagePlus image) {
List<MyInternalFrame> frames = mapWindows.get(image);
if (frames == null) {
frames = new ArrayList<>(25);
mapWindows.put(image, frames);
}
frame = new MyInternalFrame(image.getTitle(), image, save);
JPanel panel = new JPanel();
JPanel panel2 = new JPanel();
JTextArea text = new JTextArea();
String info = "Image Information: \n\n";
info += "Image Name: "+image.getTitle()+ "\n";
info += "Pixel Size: ";
info += (image.getHeight() +" x "+image.getWidth() +"\n");
info += ("Bit Depth: " + image.getBitDepth() + "-bit"+"\n");
info+= "Bytes/Pixel: "+image.getBytesPerPixel() + "\n";
info += "Type of: "+image.getType()+ "\n";
info += "Diplay range: " + image.getDisplayRangeMax() +"\n";
info += "Display range(min): " + image.getDefault16bitRange() + "\n";
info += image.getFileInfo();
info += image.getInfoProperty();
//System.out.println(info);
text.setText(info);
System.out.println(image.getHeight());
text.setVisible(true);
text.setEditable(false);
//text.setBackground(new Color(0,0,0,0));
panel.add(text);
JScrollPane scroll = new JScrollPane(panel);
ImageWindow m = new ImageWindow(image);
panel2.add(new JLabel(new ImageIcon(image.getImage())));
JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, scroll, panel2);
splitPane.setOpaque(true);
panel.setMinimumSize(new Dimension(500,100));
panel.setBackground(new Color(0,0,0,0));
panel2.setMinimumSize(new Dimension(200,30));
splitPane.setOneTouchExpandable(true);
splitPane.setDividerLocation(290);
frame.add(splitPane);
frame.setVisible(true);
desktop.add(frame);
try {
frame.setSelected(true);
} catch (java.beans.PropertyVetoException e) {
}
frame.addInternalFrameListener(this);
return frame;
}
public List<MyInternalFrame> getFromFor(ImagePlus image) {
JInternalFrame frame = null;
return mapWindows.get(title);
}
@Override
public void internalFrameActivated(InternalFrameEvent arg0) {
// TODO Auto-generated method stub
save.setEnabled(true);
}
@Override
public void internalFrameClosed(InternalFrameEvent arg0) {
// TODO Auto-generated method stub
save.setEnabled(false);
}
@Override
public void internalFrameClosing(InternalFrameEvent arg0) {
// TODO Auto-generated method stub
save.setEnabled(false);
}
@Override
public void internalFrameDeactivated(InternalFrameEvent arg0) {
// TODO Auto-generated method stub
save.setEnabled(false);
}
@Override
public void internalFrameDeiconified(InternalFrameEvent arg0) {
// TODO Auto-generated method stub
save.setEnabled(true);
}
@Override
public void internalFrameIconified(InternalFrameEvent arg0) {
// TODO Auto-generated method stub
save.setEnabled(false);
}
@Override
public void internalFrameOpened(InternalFrameEvent arg0) {
// TODO Auto-generated method stub
save.setEnabled(true);
}
@Override
public void componentHidden(ComponentEvent arg0) {
// TODO Auto-generated method stub
save.setEnabled(false);
}
@Override
public void componentMoved(ComponentEvent arg0) {
// TODO Auto-generated method stub
}
@Override
public void componentResized(ComponentEvent arg0) {
// TODO Auto-generated method stub
Rectangle r = frame.getBounds();
m.getCanvas().fitToWindow(r);
System.out.println("resized- the real one");
}
@Override
public void componentShown(ComponentEvent arg0) {
// TODO Auto-generated method stub
}
}
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
JInternalFrame b = WindowManager.INSTANCE.createWindowFor(image);
}
}
，并在主类中，如果用户点击打开并选择一张图片，我这样做：
v= new Manager(img, s, desktop, save, fft,showInfo);
ActionEvent e = null;
v.actionPerformed(e);
这会打开图像窗口，现在假设用户打开另外4张图像，所以这称为4次。现在，当用户点击一个框架然后点击showInfo时，我想让信息类获取图像标题并显示信息。所以这是我做的：
List<MyInternalFrame> v = WindowManager.INSTANCE.getImage();
ImagePlus i = new ImagePlus(v.get(0).getTitle()); //This is where the image is null
Info n = new Info(i,i.getTitle(), desktop, save, fft);
ActionEvent s = null;
n.actionPerformed(s);
这是我遇到的麻烦!!!!!!我希望任何人都能发现错误。提前致谢。
谢谢你相关！我现在明白了。 – selena
