hi folks ,
i have requirement what it is means, am showing only one image on jsff(dynamic region). by in additionally, i have to show a af:panelbox over the af:image. is this possible.?
Never supported like this.

Centering panel boxes horizontally on a page

Experts,
I have a panelStretchLayout component on my page having 3 facets top, center and bottom. In the bottom facet i have to display 5 images inside a panel box such that they are aligned equiv distance from the left and right side. That is the same on the left side of the page and right side of the page (if the resolution changes - left hand border of the first image and right side border of the last image should be same) should be same and the panel boxes should start occupying space from the center of the bottom facet.
thks
Jdev 11.1.1.5.

Can you try this?
        <af:panelBox text="PanelBox1" id="pb1">
          <af:panelGroupLayout layout="horizontal" id="pgl1" halign="center"

Creating an image from a panel

Hi everybody,
I have a panel which extends JPanel, and wrote an image() method to extract the drawn image off the panel. For some reason, though, when I call this method, I get a dialog with a black box centered in it, and not the appropriate image.
My SSCCE is as follows:
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import javax.swing.ImageIcon;
import javax.swing.JDialog;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.SwingUtilities;
public class MyPanel extends JPanel {
    private BufferedImage image;
    public BufferedImage image() {
        int x = getWidth();
        int y = getHeight();
        //image = new BufferedImage(x, y, BufferedImage.TYPE_INT_RGB);
        image = new BufferedImage(200, 200, BufferedImage.TYPE_INT_RGB);
        Graphics2D g2 = image.createGraphics();
        SwingUtilities.paintComponent( g2, this, new JPanel(), 0, 0, x, y );
        g2.dispose();
        return image;
    public static void main( String args[] ) {
         MyPanel canvas = new MyPanel() {
              public void paintComponent( Graphics g ) {
                   Graphics2D g2 = (Graphics2D)g;
                   for( int i = 1; i <= 20; i++ ) {
                        int pos = i*50;
                        g2.drawString( "This is a test", pos, pos );
         JDialog test = new JDialog();
        JLabel label = new JLabel( new ImageIcon( canvas.image() ) );
        JScrollPane scroller = new JScrollPane( label );
        scroller.setPreferredSize( new Dimension( 500, 500 ) );
        test.add( scroller );
        test.pack();
        test.setVisible( true );
}I'm pretty sure it has something to do with the sizing of the image and the timing of the repainting--when I uncomment the commented line in image(), I get an error saying width and height can't be less than or equal to 0. But anyway, I need to paint and then show an image of what was painted, not the actual painted panel--that's what I'm having trouble with. If anyone could help me out, I'd appreciate it. Can anyone help me fix this, please?
Thanks,

Odd choice to both have the panel with a getImage() method, and also override paintComponent(Graphics).
Here is an alternate form of your code.
import java.awt.*;
import java.awt.image.BufferedImage;
import javax.swing.*;
public class MyPanel extends JPanel {
private BufferedImage image;
public BufferedImage image() {
    int x = 200;
    int y = 200;
    image = new BufferedImage(x,y, BufferedImage.TYPE_INT_RGB);
    Graphics2D g2 = image.createGraphics();
    g2.setColor(Color.yellow);
    g2.fillRect(0,0,x,y);
    g2.setColor(Color.black);
    for( int i = 1; i <= 20; i++ ) {
      int pos = i*50;
      g2.drawString( "This is a test", pos, pos );
    g2.dispose();
    return image;
public static void main( String args[] ) {
    Runnable r = new Runnable() {
      public void run() {
        MyPanel canvas = new MyPanel();
        JDialog test = new JDialog();
        JLabel label = new JLabel( new ImageIcon( canvas.image() ) );
        JOptionPane.showMessageDialog(null, label);
        JScrollPane scroller = new JScrollPane( label );
        scroller.setPreferredSize( new Dimension( 500, 500 ) );
        JOptionPane.showMessageDialog(null, scroller);
    EventQueue.invokeLater(r);
}

How to align text in Panel Box to the center

Hi,
I would like to align the text in the Panel Box to the center. Here is my code snipplet:
+<af:panelBox text="22" id="pb8"+
titleHalign="center" ramp="highlight"
background="dark"
icon="/images/warningind_active.gif"
showDisclosure="false"
contentStyle="height: 50px; width: 100%; horizontal-align:center;">
+<f:facet name="toolbar"/>+
+<af:outputText value="Update RFC with Approval Info"+
id="ot8"
inlineStyle="font-size:medium; font-weight:bold;"/>
+</af:panelBox>+
But it didn't work. The text "Update RFC with Approval Info" is still align to the left by default.
Any ideas?
Thanks.

You can't do it without panelGroupLayout. Try this way...
        <af:panelBox text="PanelBox1" id="pb1" titleHalign="center" ramp="highlight"
            background="dark">
            <f:facet name="toolbar"/>
           <af:panelGroupLayout id="pgl1" layout="horizontal" halign="center" valign="top">
            <af:outputText value="***centered***" id="ot1"/>
           </af:panelGroupLayout>
        </af:panelBox>

Getting the bounds of a drawn image on a panel

Hello, I have a problem with getting the bounds of a drawn image on a panel...Since it is drawn as graphics, i tried getClipBounds and since my class extends JPanel i tried to get the bounds from the panel but neither of them worked properly. It only gets the bounds of a jframe that contains the panel.Then i tried to put the panel in a layeredpane and then a container; but this time the image disappeared completely. Hope someone can help or tell me what I am doing wrong. Thanks in advance. Here is the code below:
By the way what I am trying to do in this code is basically zooming the image in and out by dragging or the mouse wheel. But I need to get the bounds so that I can use this.

You'll need a stable point in the component to track and orient to the scaling transform(s).
From this you can construct whatever you need in the way of image location and size.
Let's try a center–of–image tracking point:
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
import java.awt.image.BufferedImage;
import javax.swing.*;
import javax.swing.event.MouseInputAdapter;
public class ZD extends JPanel {
    BufferedImage image;
    Point center;
    AffineTransform at = new AffineTransform();
    Point2D.Double origin = new Point2D.Double(0,0);
    public ZD(BufferedImage image) {
        this.image = image;
        center = new Point(image.getWidth()/2, image.getHeight()/2);
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2 = (Graphics2D)g;
        g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
                            RenderingHints.VALUE_INTERPOLATION_BICUBIC);
        g2.drawRenderedImage(image, at);
        g2.setPaint(Color.red);
        g2.fill(new Ellipse2D.Double(origin.x-1.5, origin.y-1.5, 4, 4));
        g2.setPaint(Color.blue);
        g2.fill(new Ellipse2D.Double(center.x-1.5, center.y-1.5, 4, 4));
    private void setTransform(double scale) {
        // keep image centered over Point "center"
        double x = center.x - scale*image.getWidth()/2;
        double y = center.y - scale*image.getHeight()/2;
        origin.setLocation(x, y);
        at.setToTranslation(x, y);
        at.scale(scale, scale);

        test.addMouseMotionListener(test.mia);
    /** MouseAdapter okay in j2se 1.6+ */
    private MouseInputAdapter mia = new MouseInputAdapter() {
        final double SCALE_INC = 0.05;
        final int SCALE_STEP = 20;
        double scale = 1.0;
        double lastStep;
        public void mousePressed(MouseEvent e) {
            Point p = e.getPoint();
            center.setLocation(p);
            //System.out.printf("center = [%3d, %3d]%n", p.x, p.y);
            setTransform(scale);
            repaint();
        public void mouseDragged(MouseEvent e) {
            // scale up/down with relative vertical motion
            int step = (e.getY() - center.y)/SCALE_STEP;
            if(step != lastStep) {
                scale += SCALE_INC*((step < lastStep) ? -1 : 1);
                //System.out.printf("step = %3d scale = %.3f%n", step, scale);
                setTransform(scale);

I can't view multiple images in tabbed panels in photoshop CC (do not have this problem in PS5 or 6)

I can't set up multiple images in tabbed panels in photoshop CC (do not have this problem in PS5 or 6). Has anyone had this problem with CC and if so do they know the fix?

I just discovered something really weird. If I open the images in
photoshop (and the tabs are not showing) and then open another window on
top of photoshop (for example word or safari) , then the images and tabs
show in the photoshop window. But if I move Pshop to the front screen then
the tabs disappear!

I gave you a simple solution in your other posting. You never responded to the suggestion stating why the given solution wouldn't work, so it can't be that urgent.

Photoshop Elements 5.0 - won't let me change image aspect ratio. Box is greyed out. Have reinstalled

I've been using Photoshop Elements 5.0 for years. As of today, it won't let me change image aspect ratio. Box is greyed out. Have reinstalled the program with no change

Where in photoshop elements 5 are you seeing the "Box" geyed out?
Or how are you trying to change the image aspect ratio?

Displaying thumbnail images in another panel when it mouse clicked

hi,
I am using JAI, what i am trying to do is i am decoding the tiff file and creating thumbnail of that images and adding thumbnail images to one panel and enlarged images to another panel using DisplayJAI. Now when i will click i thumbnail images on left panel then that image should be display to another panel on right side. Adding both panel to JSplit panel.
I have no idia how to do it, i tried to do in different way but not able to do that. I hope anybody can give me the hints about this.
Thanks

i am adding thumbnail of all images in left panel and enlarged view of each thumbnail is added in right panel , and what i require that when i click thumbnail in left side it's corresponding enlarged image should be visible, suppose in right panel page no. 1 is visible and when i click thumbnail of 13 page in left panel that should be in viewport of right panel.You should put your right panel inside a JScrollPane and call [scrollRectToVisible() |http://java.sun.com/javase/6/docs/api/javax/swing/JComponent.html#scrollRectToVisible(java.awt.Rectangle)] from your panel. You can put the rectangles corresponding to enlarged images in a hash map with the keys being some unique attribute of your thumbnails in left panel. That will help in getting the rectangle to make visible, real fast. Or, you can just put the rectangles in some array indexed according to the thumbnails in left panel.
I also want to hide the left panel, i think it's possible by Frame.Yes it is possible, but you said you have both your panels in a split pane, so maybe you can use its setDividerLocation() function to hide your left panel.
Thanks!

Adding images in custom dialog box

Hi!
Do you know if it's possibile to insert an image in a custom dialog box? I mean during the custom dialog box design (during the .dre file creation).
Thanks to all!

Hi Stemens,
I'm hesitant to answer your questions anymore because somebody always comes behind and shows everybody how much I don't know Anyway, I do not know of a way. I remember that there have been other developers discussing this and I think everybody just gave up. I have never seen an image in a dialog box, so that tends to indicate to me that no one has found a way.

Hide/Show a Panel group or Panel Box with a command link

I need to show and hide a panel group/box that has a lot of components inside ..with a command link ...I need to do this with partial submit ....please advise.
<af:commandLink >
hide the panel box with all the comps inside it ..change commandlink text ....
use the same command link to show the panel box and change the command link
text back
</af:commandLink>
<af:panelGroup layout="vertical">
<af:panelBox>
<af:panelGroup>
ALOT of components .......
</af:panelGroup>
</af:panelBox>
</af:panelGroup>
I tried with partial trigger ..I tried everything i know ..it did not work .....it only worked I do a I full submit and setting some processScope(session) variables ..
Thanks.

Hi,
- have a managed bean in session scope
- define a boolean variable that is set to true
- expose the variable through a public method
- use EL on the panelBox rendered property to link to this boolean method
- define an action listener on the command link and set the autosubmit property to true
- use the action listener to set the boolean value
- define a value for the ID property of the command link
- set the ID vaule to the PartialTrigger property of the panelGroup component
