Main Activity. Line 52: Define a class of the type StringSelection that implement a text data flavor. * * @return Returns an Image if successful; otherwise returns null. JavaWorld's most popular long-running series, featuring new and classic Java programming tips from your peers in the Java developer community. This interface is used to notify when the data originally placed in the clipboard has been overwritten, Represents all the data types that transferable support, One type of transferable that is supplied with Java, Wrapper to objects passed to the clipboard, Exception thrown by transferable for an unsupported data flavor, Set the content of the clipboard along with owner object, Get the content of the clipboard in the form of a Transferable object. This is probably the most useful version of the script as it allows you to generate text in JavaScript, which is not visible on the page at all, then place that text on to the clipboard. Any content that is overwritten in the Clipboard means that the ClipboardOwner object has lost its ownership of that content. JTextArea textArea = new JTextArea (""); Now, paste the clipboard text −. It includes three methods, which are defined in the following table: The three Clipboard class methods above allow you to name the clipboard, send information to it, or get information from it. document.execCommand('Paste');} function copyToClipboard(s) {var input = document.getElementById("ta1"); input.focus(); input.select(); document.execCommand('Copy'); if ( document.selection ) {document.selection.empty();} else if ( window.getSelection ) {window.getSelection().removeAllRanges();}} Relevant Links Many of the user components provided by the Java GUI, such as Swing or AWT, have built-in support of this mechanism. The most common methods of this class are the setContents() and getContents(). Get the content of the clipboard. This means that when we extract data from an application, however simple it seems visibly, it also copies the formatting and other information about the data in the Clipboard. Java offers two types of clipboards: local and system. What usually happens is that when we issue a cut or copy command from a user component, the data is extracted to a global memory location managed by the underlying platform's Clipboard manager. While retrieving content from the Clipboard, care should be taken to check if the data flavor is supported by the receiving component where the data is intended to be pasted. Notice that we must supply the owner of this class, in this case, this applet. After this brief tour of the classes involving clipboard manipulation, we'll follow the suggested recipe to write a simple applet that transfers text to the system clipboard. Restart your browser. This method will cause your program to relinquish ownership of the clipboard. Line 27: Create a clipboard object that references a local clipboard. This article will give you a good understanding of how to send and get information from the clipboard in Java. FlavorListener s may be registered on an instance of the Clipboard class to be notified about changes to the set of DataFlavor s available on this clipboard (see addFlavorListener (java.awt.datatransfer.FlavorListener)). It gets the System Clipboard from the default Toolkit. With any luck, this issue will be addressed in the next release of the JDK. This object is notified as soon as some other data overwrites the content of the Clipboard. Because Java is a multiplatform language, and because operating systems behave differently toward clipboards, the authors of the Java language had to come up with a mechanism to deal with subtle differences. If the clipboardData object exists, then it will contain the items property (by default undefined if the clipboard is empty): var items = pasteEvent.clipboardData.items; Because the clipboard only accepts objects of type Transferable, the object that you want to send to the clipboard must implement this interface. One disadvantage of using the system clipboard is that you can only transfer text data. Create a class called xxxxSelection. Line 41: Set the sourImage control to Image.gif. Use the getContent method in the Clipboard class. The ClipboardOwner, also an interface defined in java.awt.datatransfer, refers to the owner of the contents of the Clipboard. Java provides no implementation of a cut operation. Define a class to access the clipboard. Otherwise, an exception is thrown. Quick intro to JavaFX CSS. Line 53: Set the content of the clipboard to the fieldContent class that we defined on the previous line. I'm following the established convention of use with the StringSelection provided in the JDK, but you can name this class anything you want. It is primarily used as a means to provide data for the transfer operation. Create a class called xxxxSelection. For example, an image class can be represented as a Java class or as an array of bits (GIF, JPEG, and so on). Local clipboards are only available inside the virtual machine that your applet or application is running. Here, xxx should name the type represented by this flavor. Bear this in mind when experimenting with the following code that everything copied cannot be pasted everywhere. The data retrieved from the Clipboard with getContents() also receives a Transferable object. The setContents() method is used to set contents to Clipboard, like cut-copy operations, and the getContents() method is used to retrieve the content from Clipboard, like the paste operation. If you are planning to transfer text, the StringSelection class should be used instead. Lines 111 to 130: Implement the Transferable methods. This article focuses into this API to give an idea how to implement it in Java code. To do this, you must manually erase the data once it is copied to the clipboard. These classes, listed in the table below, are all part of the java.awt.datatransfer package. Here’s the source code for a Java method that I use to retrieve an image from the system clipboard. Line 68: Ensure that the content is not null and that the flavor we are looking for is supported. The instance of this class is used to refer to the system resource called Clipboard. System clipboards are directly linked with the peer operating system, allowing your application to transfer information among any applications running under that operating system. The image will implement its own flavor. Copy data into the clipboard and then import the clipboard data into MATLAB ®. Step 3. textArea.paste (); Note − Let’s say our clipboard text is “This is clipboard text that got inserted in the text area”. Accessing a particular local clipboard is as easy as referring to it by name. The Clipboard class defines many other methods, but all centers around a few classes, such as DataFlavor, Transferable, and ClipboadOwner, and to implement data flavor events through the FlavorListeners event classes. We then get the content of the source text field. It is for this reason that when we cut or copy a text from, say, a Swing textfield, it is also available to any other Java or non-Java application, say, the notepad. Line 66: Get the content of the clipboard. To access the system clipboard, assign a reference from the system clipboard to the Clipboard class, such as: Clipboard clipboard = getToolkit ().getSystemClipboard (); On the other hand, to create a local clipboard you only need to create a Clipboard object with the name that you want to assign to it, for example: Clipboard clipboard = new Clipboard ("My first clipboard"); Accessing the system clipboard or creating a local clipboard is different but straightforward. In Listing 2, we went further by implementing our own data flavor java.awt.Image. If the MimeType is application/x-java-serialized-object, then the result will be the same as if you called the previous constructor. 4. clipboardData is IE only, it works with character string and return null if we paste an image. In this article, we are using MS Word to create a new document and copy few lines from some java tutorial for reference in our demonstration. Java provides a dedicated class called Clipboard, defined in java.awt.datatransfer. In general, you can only access the clipboard during a systemcut, copy, or paste event.

One way to transfer java objects is to encode them as string and put into the system clipboard, then retrieving the string from the system clipboard and decoding them to the respective object. You will then be asked if you want to leave the data in the clipboard. Line 123: Return the content of the clipboard with this method. Line 71: Get the data in the appropriate flavor. Select the lines below, right-click, and then select Copy . args){ TextTransfer textTransfer = new TextTransfer(); //display what is currently on the clipboard log("Clipboard contains:" + textTransfer.getClipboardContents()); //change the contents and then re-display textTransfer.setClipboardContents("blah, blah, blah"); log("Clipboard contains:" + textTransfer.getClipboardContents()); } /** * Empty implementation of the ClipboardOwner interface. It is for this reason that when we cut or copy a text from, say, a Swing textfield, it is also available to any other Java or non-Java application, say, the notepad. Implementing the ClipboardOwner interface is relatively straightforward because there is only one method to implement. Finally, we'll cover the multiple personalities of clipboards and how they provide support for more than one data flavor. This means that the global memory we are referring to is actually outside the periphery of the application from where it was extracted. In reality, a DataFlavor class is a wrapper to a MIME type. The Toolkit is an abstract superclass that comprises all the functionalities of the Abstract Window Toolkit and binds with the usability of native windowing toolkit implementations, such as the effect of scrolling, visibility of window, sizing, modality, and so on. The returned DataFlavor will have representationClass = representationClass and a mimeType = application/x-java-serialized-object.
