JEditorPane displaying "image" arrow-icon

windows 1.4.1
using a JEditorPane to display html.
little icons with the word "image" in an arrow pointing left are sprinkled through the page rendering. any ideas on what this is about?
comments:
i render the same URL in two JeditorPanes. in the first it paints successfully (no arrow icons). in the latter it gets the arrow icons.
successful rendering JeditorPane is in a JFrame.
bizarre rendering is in a JWindow.
thanks

i set the editorpane to setEditable(false) and the arrow icons went away.

  • Alias to Image does not display image preview icon (Regression!)

    I noticed that an alias to an image no longer displays the underlying image preview in the icon, instead you get the standard "JPEG" icon.
    I have turned on icon previews (since other images in the same folder are correctly displayed) and all that. Also if you press Space on the Alias, the fancy Preview window will open and show the correct image. The icon however is dead. I've tested this with many images and with both OS created Aliases and using "ln -s".
    This seems to apply to all kinds of alises that in the past would show the icon of their parent, not only images.
    The alias "arrow" overlay is enough to inform the user that the file is an alias, there is no need to display the standard "JPEG" icon, that is so passé.
    Not very leopardy.

    The same thing appears to be a latent bug from Tiger -- I am seeing this in 10.4.11, and as Rob notes, it's not always consistent.
    What's worse, Rob's suggestion won't work for me... because the "Select New Original..." button is greyed out! I realize this is technically a Leopard thread, but I can't imagine this was deliberately changed between 10.4 and 10.5, so I would think it would be applicable pretty broadly.
    Any ideas or suggestions would be very welcome indeed.

  • Problem Displaying Images in a JFrame

    I am writing a program that displays images on a JFrame window. I have been reading the other postings about this topic however I have not been able to make my code work. I am hoping there is some obvious solution that I am not noticing. Please help, I am very confused!
    public class WelcomeWindow {
    private JLabel label;
    private ImageIcon logo;
    public WelcomeWindow() {
    label = new JLabel();
    logo = new ImageIcon("/images/logo.gif");
    label.setIcon(logo);
    this.getContentPane().add(label);

    Instead of a JLabel, have you tried to use a JButton containing the Icon?
    Also (but I think you've done it already), you could do that :
    File iconFile = new File("/images/logo.gif");
    if (!iconFile.isFile()) {
    System.out.println("Not a file");
    That way you'll be certain that the path given is correct.
    Hope this helps.

  • Display image in html mail

    I was recently sent an email that used an HTML stationery wih several photos embedded in it.  The email opens normally, but all of the images are icons, displaying file name and size.  If I click the icon, the image opens correcly in a separate window. 
    I am running OS X 10.7.3 and Mail 5.2 (1257) and have checked "display remote images in html email" in preferences.  A friend with identical software versions receives the same email and the photos are visible in the original email. Suggestions?

    No-one replied, but I found a solution on another board. Run Terminal (do a Spotlight search if you don't know where to find this), and type: (or copy and past the next line)
    defaults write com.apple.mail DisableInlineAttachmentViewing -bool false
    This will force Mail not to disable inline attachment viewing. Obviously, to reverse this, simple replace 'false' at the end with 'true'.

  • I have connected my new Macbook Air to my existing Samsung large external monitor with a VGA adaptor but I can't get the full mac desktop to display. No icons but then websites are coming up. Help!

    I have connected my new Macbook Air to my existing Samsung large external monitor with a VGA adaptor but I can't get the full mac desktop to display. No icons but then websites are coming up. Help!  Further info:  I am a complete newbie to Mac.  Had three macs prior to 2000 then four PCs.  Just come back and struggling a bit with the unfamiliarity. On my old PC laptop I could simply switch from the laptop screen to the large external monitor (and back)  with the F4 function key.  While I can get the background image from my MBA to display, that's it.  Until I noticed on the far left of the external monitor, the very edge of one of the web pages I was on.  So Idragged it over to display in the centre.  But that's all that's there.  And now I have gone out of those web pages but they are still displaying on the monitor.  There is some wierd disconnect.  I'm sure it is just a setting thing.  Will keep searching for answer but any advice welcome!

    Your dsplay is getting extended onto the external monitor. Chcnage the setting to duplicate it or only display on the external monitor and you should be fine,
    Let me know if this worked for you.

  • Problem in displaying images one by one in JList

    I have a problem in displaying images one by one in Jlist. I want to show 100 images as a thumbnailview in jlist but it is talking too much time to show all the images after scalling 100 images to thumbnail view and making it into ImageIcon. So, i thought that it would be better way to show one by one after scaling it into thumnailview. But my renderer is getting calling after 100 images scaled down and setting into list. I have posted my code 2 days back but there is no reply.
    http://forum.java.sun.com/thread.jspa?threadID=789943
    I donno where i am missing in this code.
    Plz suggest me some solution for it.

    Where is the scaling done? In the ListCellRenderer? Regardless of where that is being done, I assume you are caching the scaled images after you scale them, right? If not, consider adding some sort of caching.
    This should do the trick...
    Rework your ListCellRenderer to check to see if a scaled version of the image is available. If not, start a thread to do the scaling and create an ImageIcon. In the meantime, while that thread is running, have the renderer return some sort of stock icon, like a little generic image icon. When the scaling thread completes, make a call to repaint() on the JList so the cell renderer gets re-asked for the icons. This time around, the renderer should notice that a scaled version (the ImageIcon) is available. Return that. So, this method doesn't guarantee that the images will be produced in order, 1...2...3..., but it will return images as they become available, and the overall JList rendering won't wait until all 100 are ready. If you want them returned in order, just do all of the scaling in a single thread and queue up the images to be scaled, in order.
    I hoped this helps. (If it does, please throw me some Duke Dollars.)

  • Help with displaying images (gif, jpeg...) within a JFrame (or similar)

    Hi all,
    i'm new to the forum and i'll be granted if you kind gentlemen/women could use some advices for my gui home application.
    My purpose is to display a static image in a container (i'd prefer to use javax.swing objects, but if you think that java.awt is more suitable for my app, please feel free to tell me about...). I used a modified code from one of the Java Tutorial's examples, tht actually is an applet and displays images as it is using the paint() method. I just can't realize how to set the GraphicContext in a JFrame or a JPanel to contain the image to display, without using applets. Following part of the code I use (a JButton will fire JApplet start, JApplet is another class file called Apple.java):

    Read the Swing tutorial on "How to Use Labels" or "How to Use Icons" for working examples:
    http://java.sun.com/docs/books/tutorial/uiswing/TOC.html
    By the way you should never override the paint() method. Custom painting (not required in this case) is done by overriding the paintComponent(...) method in Swing. Overriding paint() is an old AWT trick.

    I am using Oracle JDeveloper 11g R2.

  • WD4A : Displaying images in ALV table

    Hi,
    Does anyone know how to display images in ALV tables in Webdynpro?

    Hello,
    You can define an attribute in the context with the type CHAR 30 and define it value like an icon from WDA (like ~Icon/GreenLed). And then you need to create an method to define the attributes of the column that will have the image like follows:
    METHOD display_alv .

  • Default image loading icon changed

    Hello,
    I installed a social app that has hijacked my "image loading" icon.
    What I mean is that when I am using ANY app that requires time to download an image, the icon that displays on the screen to indicate that there is a pending image loading has changed and been hijacked by this social app.
    I have wiped my ipad to factory defaults and set it up as a new ipad WITHOUT syncing any data. I downloaded an app fresh like dropbox and flickr stacker, and the chat app image remains (Even though the social app has NOT been installed on this fresh wipe) when pending an image download
    I'm hoping somone has an idea as how to get rid of this blasted artifact!
    TIA!

    If I remember well, in the Report Attributes, you should select the linked column. At the link image, there are 2 edit images(the default is the big one), but there is one more image which is smaller.
    Hope it helps.

  • Image Adjust icon missing from tool bar

    I've got the latest Keynote running on my Macbook, but it seems to be missing the Image Adjust icon, the one that sits right next to Inspector icon on my desktop G5 running the exact same version of the program.
    I can get to image adjust through the menu bar going to View>Show Adjust Image, but on my desktop computer, there is an icon right in the Keynote toolbar.
    Can't for the life of me determine why it doesn't present itself on my laptop. Any ideas? Many thanks, Bob Krist

    Try right clicking on the toolbar and choose Costumize Toolbar (or via the View menu (it should be the last option in the View menu) then you will see a array of icons which can be placed on the toolbar as you see fit.
    and maybe the window is to narrow to be able to display the icon and it falls of at the end, there then should be an '>>' icon, which when pressed should show all the icons that dont fit.
