Customize Netbeans Platform Splash Screen and About Dialog

October 18th, 2007 | by Tonny Kohar |

During development of our product Sketsa SVG Editor, we need to customize the default Netbeans Platform About Dialog and splash screen as part our product branding.

Nb Platform default about dialog      Nb Platform custom about dialog

Note: this is tested on Netbeans IDE 6-beta1

Customize the Splash Screen

Create the image using any image editor application to suit your particular branding. If you want to have single image for both splash and about dialog, please make sure the image have dimension 259×252 px, so it will fit nicely with the available image space in the about dialog.

Note: the about dialog will automatically use the splash screen image, if it is not supplied with its own image to use.

Update: On Netbeans 6 beta2, it no longer share the splash and about image, so you need to have two files ready: splash.gif and about.png

Now on the project suite node right click and choose properties, and go to Build-Splash Screen section. Click the browse and select your desired image for the splash screen.

In this dialog you may also customize the progress bar and running text color, size, and position

Customize the About Dialog

On the about dialog you may customize the copyright info using the following methods. In the project suite (under File, not project) expand the branding folder as show in the image

Nb Platform branding folder

Add the following in the

LBL_Copyright=<div style\="font-size\: 12pt; font-family\: Verdana, 'Verdana CE',  Arial, 'Arial CE', 'Lucida Grande CE', lucida, 'Helvetica CE', sans-serif; ">
Copyright &copy; 2003-2007 KIYUT. Please visit <a style\="color\: \#1E2A60;" href\="http\://">http\://</a>.<br>
Warning\: This computer program is protected by copyright law and international treaties. Unauthorized reproduction or distribution may result in severe civil and criminal penalties, and will be prosecuted to the maximum extend possible under the law.</div>

Customize the About Dialog Image (Optional)

If you need to have different image for splash and about dialog, you need to supply the about image file.
The image must be named about.png (not gif) with dimension 259×252 px.

The file about.png must be placed under

Nb Platform branding folder

    Dear Tony,

    Thanks for the article.

    I have managed to customize the About dialog box in NB6. However, how do I change the link ( when the top image is double clicked?

    To customize the link for the About image, you need to add the following into the org-netbeans-core.jar (the where you set LBL_Copyright)

    Hi Tonny: I just wanted to drop a quick note to say that this blog entry really helped me today when I was trying to remember where the URL_ON_IMG property gets set. Nice work!

    Hi Tonny: I tried this with NetBeans IDE 6.0 (Build 200711261600) and it doesn’t seem to be picking up my branding. It does pick up the Branding image but not the URL_ON_IMG and LBL_Copyright. Any ideas if this changed since the Beta version.

    Thanks very much.

    As far as I know, it is working up to Netbeans 6.0.1, because we use it. Please make sure you put your branding in the correct and folder (core and module folder is different).

    Also note that since Netbeans 6-beta2, it no longer share splash and about image, so you need both of them

    Nice tutorial, I’ve been trying to know how to do this for the past 6 months!!!


  8. By Steve Nelson on Mar 26, 2008 | Reply

    Thanks Tonny.

    By the way, if the folder org-netbeans-core.jar is not there, you can create it along with the other folders org, netbeans, core and ui then create a file and add the information in you have supplied.

    But beware: not only will you maybe have to make the correct directories, but also make sure the org/netbeans/etc. is within the org-netbeans-core.jar file.

    Still works with NB6.1

    I cannot get this to work. I am using the netbeans platform but not the IDE. I’ve been using Netbeans since 5.0 and have had branding working fine. However, with the upgrade to 6, my picture is no longer being used. Do I have to rename my branding jar to org-netbeans-core.jar? If not, where do I need to install it so netbeans uses it?

    It is very important to use the correct folder structure and the naming of jar is very important as well.

    Is the size 259×252 right?
    It is a rectangle, not square.
    I have my splash 432×266. It was made according to some splash image in NB 6.1.

  13. By Tonny Kohar on Feb 25, 2009 | Reply


    As far as I know Netbeans does not put a constraint for the image size. So you could use any reasonable size for the image.

    Ahh almost forget. The important things is the folder structure, not the image size

    I have a question about splash image. I try to put an image with a blurred border. To do that my image has transparency color.
    When i configure this image with netbeans wizard (project properties) , i can see that i have a splash.gif file (and when i open it into netbeans, display it correct) but when i start my application, there is a background color (blank) which is applied and my splash is so … ugly.

    Somebody has try this (a basic example is to make a splash with round corner) ?

    can we use another image format ?

    We have been trying to change the Application Icon. There is an option under Properties/Build but it does nothing. If you look at the help it says:

    “Note that this icon does not set the executable’s icon. If you want to customize the executable’s icon, you need to make use of an external resource editor, many of which are freely available on-line.”

    but they don’t say what needs to be edited in the first place. Any help will be greatly appreciated.

  17. By Tonny Kohar on Apr 2, 2009 | Reply


    For Application icon, please see this blog entry and add the following to the build-brand ant target

    <copy todir="${basedir}/branding/core/core.jar/org/netbeans/core/startup/" overwrite="true">
        <fileset dir="${basedir}">
            <include name="frame.gif"/>
            <include name="frame32.gif"/>
            <include name="frame48.gif"/>

    Please make sure it is gif file not png file. And this is the icon for the window frame. it is not executable icon (Java is cross platform), so it does not depend on any executable (exe, sh, etc)

    Thanks for this post on branding. Can you tell me where to look to change the start page as well in NetBeans or provide my own start page (when I run a module based on the NetBeans IDE)? I see it in their “welcome” project in the NetBeans build, but I want to incorporate this into my own module (app). Thanks again.

  19. By Tonny Kohar on Jun 3, 2009 | Reply


    Although I never tried it, but by looking at the Netbeans source code, the welcome screen/start page is easily customizable by the resource branding and layer.xml

    So based on the above, I guess you can easily branding the welcome screen by branding the resource bundle as described in

    Another way, is to create you own welcome screen (it is just a TopComponent). But if you create your own you must implement your own url fetching.

    note: I haven’t tried branding welcome screen, so it might or might not works.

    I’ve got almost everything going for the about dialog. I have one problem with resizing the About dialog. I am using a different image for the splash and about because the splash image is too large for the About dialog. Is it possible to set the height and width of the About dialog in this situation?

    Thanks for your branding posting. It was a huge help.

  21. By Tonny Kohar on Jul 15, 2009 | Reply


    Unfortunately, as far as I know, there is no way to specify the width * height for the About Dialog explicitly.

    However, you can influence the width (not height) by using the about.gif (width of the image) as the width of the About Dialog.

    note: it is the width of the image plus some few pixel margin.

    If you mean disable the link on the About Dialog. then just leave url empty eg:

    Very good blog.
    I though I should add that the branding folder which contains code and modules should be right inside the suite folder.

    Thanks for your blog.

    Thanks for this post. I am starting with NetBeans Platform development using NB 6.7. Created a platform application, was able to brand the splash screen but for some reason the about dialog text does not seem to change. The image on the about dialog has changed. I tried as described above by adding LBL_Copyright in under Branding/Modules…
    Any help is greatly appreciated.

  26. By Tonny Kohar on Oct 7, 2009 | Reply


    The LBL_Copyright must be located under Branding/Modules/… in the suite project (not in the module project) and make sure the path is correct.

    I recently upgraded my custom branded project from 6.5 to 6.7.1. If I run the application from NB, or if I run in debug mode, the images show as expected. However, after building the distribution package, the images and all other branding are no longer there, and the default values are used. Any ideas? Thank you.

    Hello, I’ve been trying to change the about image. I did set the image.png in the startup folder, clean the project but it doesn’t change it. Do I need to do something else?

    make sure the path is correct and it must be under project suite

    Using NetBeans 6.8:
    The project must include the platform11 / Core-UI Platform Module or the About menu item will not show up. The automatic resolver didn’t include this module.
    Also, the Feedreader sample’s About screen worked with just the splash.gif (no about.png) so apparently they’ve resolved that problem too.
    Thanks for all the hints here!

    The latest NetBeans IDE version 6.9.1 has a good resource editor for Branding Platform applications. We can change icons, splash screen, and even the resource text from this dialog box and the related files are automatically written by that dialog box.

    IMO branding platform application in NetBeans has become a piece of cake. I am loving it.

    with regards

    I want to add some more information in the About Dialog for my product.
    The default information displayed is :

    Product Version: NetBeans IDE 6.5 (Build 200811100001)
    Java: 1.6.0_11; Java HotSpot(TM) Client VM 11.0-b16
    System: Windows XP version 5.1 running on x86; Cp1252; en_US (nb)
    Userdir: C:\Documents and Settings\user1\.netbeans\6.5

    I have seen the where you can specify the copyright information. But I also need to add some other information, the values of which will be populated dynamically.
    EG: The Session start time or the user logged in.

    Can you please provide some help on this.

    Thanks in advance.

    As far as I know, currently the About Dialog is not very customizable. You can only change a little bit through properties file.

    So if you want to customize it, IMHO the best way is to hide the original About Box through layer.xml, and create your own About Box and put it into the layer.xml.

  37. By Pankaj on Jan 13, 2011 | Reply

    Thanks for your reply. Can you please let me know where I can find this layer.xml?

  38. By Tonny Kohar on Jan 14, 2011 | Reply


    For more info regarding layer.xml, please read the following


    One of the simple ways, is to add action to the menu bar for displaying your own created About Dialog

    after the image,netbeans will open the internal browser.I want to open a system default can I do.


  40. By Tonny Kohar on Jun 3, 2011 | Reply


    To enable external (system default browser), please include external html broswer under ide cluster.

    To enable it:
    – On the suite project, right click choose properties
    – Go to Library section
    – Under ide section, tick the external html browser
    – As usual just rebuild and done

    I have a similar issue to Darren. I have managed to change the url that is launched when clicking on the about box image, but want it to open in the external (system default) browser. My project is a maven project. Do I need to include an external html browser dependency?

  42. By Tonny Kohar on Jun 19, 2012 | Reply


    yes you need to include external html browser
