How do I get the text of two JLabels when copying JLabel's text with TransferHandler?
Label1111111 How can I keep the text of both JLabels when copied to Label2222222.
For this reason, I will take control of two Jlabel's texts. This shape can only get the text of JLabel, which was first held. Thank you in advance for your help.

Maybe in this way. I added inner class MyLabel and console output in your handlerLabel. Ctrl+v this under your main. It will print to console the original String property of each MyLabels.
public class MyLabel extends JLabel {
String original;
public MyLabel (String text)
{
super(text);
this.original=text;
}
public String getOriginal() {
return original;
}
public void setOriginal(String original) {
this.original = original;
}
}
public deneme2() {
JPanel panel= new JPanel();
MouseListener listener = (MouseListener) new DragMouseAdapter();
MyLabel label1 = new MyLabel("Label1111111");
handlerLabel(label1);
label1.addMouseListener(listener);
panel.add(label1);
MyLabel label2 = new MyLabel("Label2222222");
handlerLabel(label2);
label2.addMouseListener(listener);
panel.add(label2);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 450, 300);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
contentPane.setLayout(new BorderLayout(0, 0));
contentPane.add(panel);
setContentPane(contentPane);
}
private void handlerLabel(MyLabel lbl) {
lbl.setTransferHandler(new TransferHandler("text") {
#Override
protected void exportDone(JComponent source, Transferable data, int action) {
if (action == COPY) {
System.out.println(((MyLabel) lbl.getDropTarget().getDropTargetContext().getComponent()).getOriginal());
}
}
});
}
Edit: check this out. Ctrl+V this under your main. It will print to console text of source label and text of target label, also the original property. Class MyLabel implements DropTargetListener , which is then registered by new DropTarget(this, this). Then we define what will happen in overriden drop method.
public class MyLabel extends JLabel implements DropTargetListener {
String original;
public MyLabel(String text) {
super(text);
this.original = text;
new DropTarget(this, this);
this.setTransferHandler(new TransferHandler("text"));
final MouseListener listener = new MouseAdapter() {
#Override
public void mousePressed(final MouseEvent me) {
final MyLabel label = (MyLabel) me.getSource();
final TransferHandler handler = label.getTransferHandler();
handler.exportAsDrag(label, me, TransferHandler.COPY);
}
};
this.addMouseListener(listener);
}
public String getOriginal() {
return original;
}
public void setOriginal(String original) {
this.original = original;

It also prints original property to console. Those could be organised differently (MyLabel, MyLabelTransferable, MyLabelDropTargetListener, MyLabelTransferHandler classes, just to give an idea for future refactoring) but it works in this way too. Consider it a quickfix for your use case.
So main class is this:
public class Deneme2 extends JFrame {
private static final int COPY = 0;
private static final int NONE = 0;
public static void main(String[] args) {
Deneme2 mainFrame = new Deneme2();
SwingUtilities.invokeLater(() -> {//let's get that frame on EDT rollin lambda style:)
mainFrame.setVisible(true);
});
}
public Deneme2() {
JPanel panel = new JPanel();
panel.setLayout(new BorderLayout());
MyLabel label1 = new MyLabel("Label1111111a");
panel.add(label1, BorderLayout.WEST);
MyLabel label2 = new MyLabel("Label2222222b");
panel.add(label2, BorderLayout.EAST);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setBounds(100, 100, 450, 300);
panel.setBorder(new EmptyBorder(5, 5, 5, 5));
this.add(panel);
}
}
Then MyLabel.java :
public class MyLabel extends JLabel implements DropTargetListener, Transferable {
String original;
protected static final DataFlavor MYLABEL_DATA_FLAVOR = new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType + "; class=\"" + MyLabel.class.getCanonicalName() + "\"",
"MyLabel label");
protected static final DataFlavor[] SUPPORTED_FLAVORS = {MYLABEL_DATA_FLAVOR};
public MyLabel(String text) {
super(text);
this.original = text;
new DropTarget(this, this);
this.setTransferHandler(new MyLabelTransferHandler()); //here we use our custom TransferHandler
final MouseListener listener = new MouseAdapter() {
#Override
public void mousePressed(final MouseEvent me) {
final MyLabel label = (MyLabel) me.getSource();
final TransferHandler handler = label.getTransferHandler();
handler.exportAsDrag(label, me, TransferHandler.COPY);
}
};
this.addMouseListener(listener);
}
public String getOriginal() {
return original;
}
public void setOriginal(String original) {
this.original = original;
}
#Override
public void dragEnter(DropTargetDragEvent dtde) {
if (dtde.getTransferable().isDataFlavorSupported(MyLabel.MYLABEL_DATA_FLAVOR)) {
System.out.println("Drop accept - MyLabel");
dtde.acceptDrag(DnDConstants.ACTION_COPY_OR_MOVE);
} else {
dtde.rejectDrag();
}
}
#Override
public void dragOver(DropTargetDragEvent dtde) {
//System.out.println("Drag over");
}
#Override
public void dropActionChanged(DropTargetDragEvent dtde) {
System.out.println("Action changed");
}
#Override
public void dragExit(DropTargetEvent dte) {
System.out.println("Exited");
}
#Override
public void drop(DropTargetDropEvent dtde) {
System.out.println("Drop detected");
if (dtde.getTransferable().isDataFlavorSupported(MyLabel.MYLABEL_DATA_FLAVOR)) {
Transferable t = dtde.getTransferable();
if (t.isDataFlavorSupported(MyLabel.MYLABEL_DATA_FLAVOR)) {
try {
Object transferData = t.getTransferData(MyLabel.MYLABEL_DATA_FLAVOR);
if (transferData instanceof MyLabel) {
MyLabel mySourceLabel = (MyLabel) transferData;
if (!(mySourceLabel.equals(this))) {
dtde.acceptDrop(DnDConstants.ACTION_COPY_OR_MOVE);
this.setText(mySourceLabel.getText());
mySourceLabel.setText("Empty");
System.out.println(mySourceLabel.getOriginal() + " " + this.getOriginal());
} else {
dtde.rejectDrop();
System.out.println("Drop rejected - the same MyLabel");
}
} else {
dtde.rejectDrop();
}
} catch (UnsupportedFlavorException | IOException ex) {
dtde.rejectDrop();
}
} else {
dtde.rejectDrop();
}
}
}
#Override
public DataFlavor[] getTransferDataFlavors() {
return SUPPORTED_FLAVORS;
}
#Override
public boolean isDataFlavorSupported(DataFlavor flavor) {
return flavor.equals(MYLABEL_DATA_FLAVOR) || flavor.equals(DataFlavor.stringFlavor);
}
#Override
public Object getTransferData(DataFlavor flavor) throws UnsupportedFlavorException, IOException {
if (flavor.equals(MYLABEL_DATA_FLAVOR)) {
return this;
} else if (flavor.equals(DataFlavor.stringFlavor)) {
return this.getText();
} else {
throw new UnsupportedFlavorException(flavor);
}
}
}
And then MyLabelTransferHandler.java :
public class MyLabelTransferHandler extends TransferHandler {
#Override
public boolean canImport(TransferHandler.TransferSupport support) {
return (support.getComponent() instanceof MyLabel) && support.isDataFlavorSupported(MyLabel.MYLABEL_DATA_FLAVOR);
}
#Override
public boolean importData(JComponent src, Transferable transferable) {
return src instanceof MyLabel;
}
#Override
public int getSourceActions(JComponent c) {
return DnDConstants.ACTION_COPY;
}
#Override
protected Transferable createTransferable(JComponent c) {
Transferable t = (MyLabel)c;
return t;
}
#Override
protected void exportDone(JComponent source, Transferable data, int action) {
System.out.println("Export done.");
}
}
After final edit result looks like this:
Little clarification:
protected static final DataFlavor MYLABEL_DATA_FLAVOR = new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType + "; class=\"" + MyLabel.class.getCanonicalName() + "\"",
"MyLabel label");
in MyLabel. That's important line. This will make getTransferData() return the same instance of MyLabel. If you would do it like:
protected static final DataFlavor MYLABEL_DATA_FLAVOR = new DataFlavor(MyLabel.class, "MyLabel label");
you won't be able to change mySourceLabel text to "Empty" in overridden drop() method, since you would be given a copy of that object.
Also Why shouldn't you extend JFrame and other components? . And you can provide checking for "Empty" text (if getText() returns "Empty", then don't change text in target MyLabel).
This is a service running in the background, no Activity, began operating normally, but After about four hours, there will be a ConnectTimeoutException.
Connect to xxx.xxx.xxx.xxx time out.
This problem occurs in Android 6, I did not find this issue Android 4. When this problem occurs, I have to restart this phone, after which it connects properly for some time. When this problem occurs, other network applications on the phone runs properly.

The answer is pretty obvious - because Window title is not a Swing component, it's OS native entity.
So changes don't have to go through Swing Event Queue, but go to XDecoratedPeer.updateWMName directly in case of Unix and to some other class in other OSes.
The more interesting question would be how to avoid that UI blocking, but I don't think that's possible with just Swing, you'll have to implement some lazy loading, or rendering in batches.

just pass the string to your activity and change the parameter of the functiontorun as string
I am trying to make a straight ended connection between widgets.But when I am doing so, the orientation of my connector is coming wrong.Its always coming parallel to the required one.Also , it is independent of the connecting widgets i.e when I move my widget, my connector does not move.Snippet of my code is given as :

I know this is quite old, but I was having similar issues with the gwt-connector library.
The connectors will not appear in the correct placement if you are using standards mode. Use quirks mode instead.
Additionally, you need to manually perform a connector.update() while your dnd components are being dragged (in your drag listener) for the connection to move with the endpoint while you are dragging.
