I'm creating a new JFrame from within an already running JFrame. Both frames are separate applications, but in this case, the second application gets a "plugin handle" of the first application instead of using its default stuff. For some operations in the second app, a callback is made to the first app to know what to do/display.
This way, the second application can be reused by many other applications. It is and will NOT be possible to manually start some java.exe command to achieve a real separate process.
Now, to emphasize that the second JFrame is another application, I want the taskbar entry to not be grouped together with the entry that was already there for the first JFrame. So basically this is a Windows 7 issue in combination with Java.
The icons on the taskbar are grouped together by default, there is enough space for them to be displayed separately but they simply don't.
How can I display the JFrame's icons separately on the taskbar? I can't find anything on JFrame that does what I want.

Currently I have one application that creates four new process. The four processes that are created create a JFrame, display a video on a AWT Canvas, and run some rendering processes.
My question is, if there is anyway for me to instead of having four separate JFrames, combine all of them into one JFrame. Ideally have something like a JTabbedPanel that would switch from displaying each process.
They must stay in different processes.

I have the following simple question. Is it possible for someone to have two Java Swing application windows from which events could be captured?
I have the following scenario. I have an app which runs on a touch enabled device running Windows 7. Said app spawns another child JFrame. Now, if I click on the parent frame, I get the window's focus and I can perform actions. Doing the same on the child frame also does the same getting the focus from the parent.
What I want to do, is to be able to handle click events on both screens - that is don't block the other frame when someone is interacting with the other one.
Is there a way to do something like that?
Hey so I have a Java application where I use a JFrame as the main window. My problem is when I pin the executable to the taskbar and then run the executable a second icon is placed on the taskbar instead of a "glow" being placed on top of the icon that is already pinned. In other words, two icons on the taskbar when I pin and run the executable. Is there any coding solution to this problem?
Please even let me know if you think there is no way or if you have come across this before.
There could be multiple reasons for this:
Do you have more than one JFrame getting a task-bar icon? Referencing this question: how to restrict more than one java application icon on taskbar?
It could be that the pinned version is not the same as the one that actually runs, i.e. trying pinning the second icon that appears, then using that icon in the future.
You might need a setting in your configuration if you have any, Eclipse (the IDE) seems to suffer from this problem and requires the JVM tp be specified in it's ini file, referencing: How to make Eclipse behave well in the Windows 7 taskbar?
Last Resort. The IsHostApp setting in the registry can change the way java behaves on the task bar, you would still have two icons, they would just stack:

Back in my, ahem, Visual Basic programming days, I remember it was very easy to create a multi-form program.
In the gui designer I could simply create as many forms as I wanted and then load them in my program where needed.
I'm having a very difficult time doing this in Java.
I started out using the Java FX Scene Builder but soon discovered there doesn't seem to be good MDI support. So, back to Swing. But, again, I don't see a simple way to design a multi form application.
I read somewhere that JDesktopPane was the way to go as it will allow you to have different internal frames, but there is no way, that I can see, to design multiple frames in the NetBeans gui designer.
You would think that you could hide an internal frame in the designer so you can layout another frame. While I can add multiple frames to my JDesktopPane, they all overlap each other making it impossible to design multiple frames.
Are there any tools available to do what I'm trying to do, or do I just need to bite the bullet and code the guis without the help of a designer?
In brief, I just want to create a simple application that displays three or four options on a home screen
Enter new customer
Search for existing customer
Quick estimate
And depending on which the user selects, opens the appropriate form. It would seem that this would be a basic requirement for almost any program and I don't understand why it seems like actually creating an application with multiple windows/forms was never thought of when developing the design/development tools. Thoughts? Suggestions?
If you're really keen on using the multi document interface (MDI) of the JDesktopPane, create each form in it's own class form. Don't drag them to the desktop. This will allow you to isolate them.
(You can double click a internal frame and it should enter "isolation" mode, basically making it the only thing you can see)
However, unless the windows are sharing information (ie you want to see the information in one window to change the information in another), I'd avoid it.
A better solution might be to use a CardLayout which will allow you to switch between each form as you need.
Again, I'd start by building your forms from something like a JPanel, individually, and when you're ready, add them to your main form.
I always encourage people who are coming into Swing anew to hand code their forms, it will give you a great appreciation for how to design forms and the power of the layout managers.
I Have Create a One Swing Application and I Want To Run My Swing Application In To My Local Web Browser So Plz Tell Me How Can I Do This Because For Applet Program There Is No Any Longer Process For This.
Browsers do not know to run applications. They run applets.
There are 2 ways to refactor you application.
if you wish the application to run in its own window, just write applet that calls YourApplication.main() from its method start()
If you wish to see your application into the browser's window (as a part of your web page) you have to create applet (that extends Pannel), set its layout to BorderLayout and then put the main panel of your application into center of applet. That's it.
If you do not have one panel that contains all elements, e.g. you are adding all elements directly to JFrame you have to fix your application. Create one main panel, add all elements there and put this panel to the center of your JFrame.
