Hi Cameron, Yes, you will need an extension for ULCFrame.
Please see the snippet at the end of this mail In the snippet you can add code for letting the user specify the file name and location for the image to be saved. In fact you can make PrintableFrame implement java.awt.print.Printable Interface to directly print it to a printer as described in http://forum.java.sun.com/thread.jspa?forumID=57&threadID=263262 I hope this helps. Thanks and regards, Janak PS: Sorry for the delay in replying. Last week there was some problem with our mail server and the dev list mails did not get forwarded. >-----Original Message----- >From: [EMAIL PROTECTED] >[mailto:[EMAIL PROTECTED] Behalf Of Cameron Taggart >Sent: Wednesday, May 10, 2006 11:17 PM >To: [email protected] >Subject: [ULC-developer] capture/print window > > >Users need to print the forms that they are viewing once in a while. >Anyone done this already.

It says to use java.awt.Robot (http://java.sun.com/j2se/1.5.0/docs/api/java/awt/Robot.html) to capture a BufferedImage. Once the BufferedImage is captured, I'm sure it can be turned into a PNG and sent to the user or even a PDF as the second link describes. Would this functionality need to be packaged up as a ULC extension? cheers, Cameron ------------------------------- import java.awt.AWTException; import java.awt.Rectangle; import java.awt.Robot; import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; import javax.imageio.ImageIO; import javax.swing.JFrame; import com.ulcjava.base.application.AbstractApplication; import com.ulcjava.base.application.ULCButton; import com.ulcjava.base.application.ULCFrame; import com.ulcjava.base.application.event.ActionEvent; import com.ulcjava.base.application.event.IActionListener; import com.ulcjava.base.client.UIFrame; import com.ulcjava.base.development.DevelopmentRunner; import com.ulcjava.base.shared.internal.Anything; public class PrintableFrameSnippet extends AbstractApplication { public void start() { final ULCPrintableFrame frame = new ULCPrintableFrame( "PrintableFrameSnippet"); frame.setDefaultCloseOperation(ULCFrame.TERMINATE_ON_CLOSE); ULCButton button = new ULCButton("Print Fame"); button.addActionListener(new IActionListener() { public void actionPerformed(ActionEvent event) { frame.printFrame(); } }); frame.add(button); frame.setSize(300, 200); frame.setVisible(true); } public static void main(String[] args) { DevelopmentRunner.setApplicationClass(PrintableFrameSnippet.class); DevelopmentRunner.main(args); } public static class ULCPrintableFrame extends ULCFrame { public ULCPrintableFrame(String title) { super(title); } protected String typeString() { return UIPrintableFrame.class.getName(); } public void printFrame() { sendUI("printFrame"); } } public static class UIPrintableFrame extends UIFrame { protected Object createBasicObject(Anything args) { String title = args.get("title", ""); return new PrintableFrame(title); } public void handleRequest(String request, Anything args) { if (request.equals("printFrame")) { getBasicPrintableFrame().printFrame(); } else { super.handleRequest(request, args); } } private PrintableFrame getBasicPrintableFrame() { return (PrintableFrame) getBasicFrame(); } public static class PrintableFrame extends JFrame { public PrintableFrame(String title) { super(title); } public void printFrame() { Robot r; try { r = new Robot(); Rectangle rect = getBounds(); BufferedImage image = r.createScreenCapture(rect); try { // Save as PNG File file = new File("c:\\PrintFrame.png"); ImageIO.write(image, "png", file); } catch (IOException e1) { } } catch (AWTException e1) { e1.printStackTrace(); } } } } } _______________________________________________ ULC-developer mailing list [email protected] http://lists.canoo.com/mailman/listinfo/ulc-developer
