Lang: Java
We are trying to copy the list of pojo to the clipboard in the table format.
Bullet point: what we are trying to achieve here :
1. convert list of pojo into table format
2. If the user copy it in some excel sheet then the it should be copied easily or even if the user try to copy in notepad it should print in the table format.
3. Add some meta data to clipboard to determine the pojo when we will import the table again.
For converting the list of pojo to table format i have used the jtable but i am not able to export all the jtable content to clipboard.
can anyone suggest if i should follow the jtable approach and copy the table to clipboard or any other solution is also available.
Update: as suggested in the comment I tried using the flavours
public class ClipboardTest implements ClipboardOwner {
public static void main(String[] args) {
ClipboardTest clipboardTest = new ClipboardTest();
clipboardTest.copyToClipboard();
//clipboardTest.getFromClipboard();
}
public void copyToClipboard() {
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
Pojo data = new Pojo("1", "2", "ame2", "2", "2");
MyObjectSelection dataSelection = new MyObjectSelection(data);
StringSelection selection = new StringSelection("testing string");
clipboard.setContents(dataSelection, ClipboardTest.this);
System.out.println("copied to clipboard");
}
public void getFromClipboard() {
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
Transferable clipboardContent = clipboard.getContents(this);
DataFlavor[] flavors = clipboardContent.getTransferDataFlavors();
System.out.println("flavors.length = " + flavors.length);
for (int i = 0; i < flavors.length; i++) {
System.out.println("flavor[" + i + "] = " + flavors[i]);
}
}
// ClipboardOwner implementation
@Override
public void lostOwnership(Clipboard clipboard, Transferable transferable) {
System.out.println("ClipboardTest: Lost ownership");
}
}

myobjectselection.java
public class MyObjectSelection implements Transferable, ClipboardOwner {
private static DataFlavor dmselFlavor = new DataFlavor(Pojo.class,
"Test data flavor");
private Pojo selection;
public MyObjectSelection(Pojo selection) {
this.selection = selection;
}
// Transferable implementation
@Override
public DataFlavor[] getTransferDataFlavors() {
System.out.println("getTransferDataFlavors");
DataFlavor[] ret = { dmselFlavor };
return ret;
}
@Override
public boolean isDataFlavorSupported(DataFlavor flavor) {
return dmselFlavor.equals(flavor);
}
@Override
public synchronized Object getTransferData(DataFlavor flavor)
throws UnsupportedFlavorException {
if (isDataFlavorSupported(flavor)) {
return this.selection;
} else {
throw new UnsupportedFlavorException(dmselFlavor);
}
}
// ClipboardOwner implementation
@Override
public void lostOwnership(Clipboard clipboard, Transferable transferable) {
System.out.println("MyObjectSelection: Lost ownership");
}
}
-- pojo.java
public class Pojo implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private String name;
private String name1;
private String name2;
private String name3;
private String name4;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getName1() {
return name1;
}
public void setName1(String name1) {
this.name1 = name1;
}
public String getName2() {
return name2;
}
public void setName2(String name2) {
this.name2 = name2;
}
public String getName3() {
return name3;
}
public void setName3(String name3) {
this.name3 = name3;
}
public String getName4() {
return name4;
}
public void setName4(String name4) {
this.name4 = name4;
}
public Pojo(String name, String name1, String name2, String name3,
String name4) {
super();
this.name = name;
this.name1 = name1;
this.name2 = name2;
this.name3 = name3;
this.name4 = name4;
}
}
When i am trying to copy the string value to clipboard it is working but when i am trying to copy the pojo then is it not working.
