How to make "Open File..." window in netbeans PLATFORM? - java

I need to create something like internal frame in netbeans platform, which loads file from any location.
I tried it by jInternalFrame, but I was not able to find some container to which I can add my frame. I am working in netbeans platform, which has own pre-created main window.
Pease help me by any advice, I am dealing with this about 10 hours, still without result.

Use WindowManager.getDefault().getMainWindow() as parent for JFileChooser dialog.

GUI designer in netbeans does not load a specific JPanel designer

It has been a few days that I've started using netbeans's gui designer.
I have built and tested all the panels I need for my project,
but today when I wanted to add some action listeners to my MainPanel.java class and tried to open it in design view, it didn't open.
It shows loading the panel but there is no sign of viewing it.
I can see the JPanel's code and I can see and open my other panels' design view.
It's only this one.
I searched the net but I couldn't find a proper answer.
Can anyone help me?
Does anyone have any idea what is the problem?
I'm using windows 7 and netbeans 8.0.2.
here are my design classes:
FinancialDocumentsJFrame.java
MainPanel.java
BillEntryPanel.java
ReceiptEntryPanel.java
SearchPanel.java
PaymentJFrame.java
I can open the design view of other classes. It's only MainPanel.java that dose not open and can see its code only. I'm also using some other java classes, too. Rather than form classes.
I made a new class and copied the existing class code in to it and it worked again.
Good Luck with your codes.

Two icons on taskbar when running java application

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:

NetBeans GUI designer window to change between design and source not showing

Right now I am working on a GUI application In java using the GUI builder that comes with NetBeans.
However I have found some kind of strange bug/feature, as I am no longer able to see the window that allows users to change between "source" and "design" (Design is the drag and drop NetBeans gui builder while source is the code where you can add your own methods and so forth).
NOTE: the red is censored information that is not necessary.
When I right click on a component to add event code, then it takes me to the source (without a window for me to change back to design, it goes back to design when i close and reopen it). So I know that NetBeans recognizes that this is indeed a JFrame form with the NetBeans GUI designer, and the source code is indeed availible..
I could not find any answers to this question on this site or on the web, I have tried resetting the windows but it did not work, I also couldn't find the window when I clicked on the window option. I am sure there is some easy question but I am unable to find it. Please forgive me if this was an easy question.
On the menu bar, try clicking View -> Show Editor Toolbar

Java Window in another Window

Multi-window applications often have a main-window, and all other windows are kind of 'parented' to it. Minimizing such a sub-window will hide its content and show the title-bar at the bottom-left of the screen. Also, these windows do not have their own Icon in the Task-bar, only the main-window does.
How can I make a window being attached this way to another window?
If that is possible, is it also possible without a referenfe to the actual main window?
#2: I'm embedding Java into such an application and I would like to be able to use awt or swing additionally to the native dialogs, which have this behavior by default.

have look at JInternalFrames for MDI application

Creating a Gallery in Java - Netbeans

I don't know very much about Java (I know the basics). I want to create an Image Gallery with Netbeans, but I have absolutely no clue how to do this.
What I want to do:
The User should see all Images inside a specified folder (as thumbs) and should be able to view it in "original size" upon clicking on the Photo. Also (via a Button) he should be able to "transfer" an Image file to that folder.
So basically I have a database of misc. articles, each article has some Images in a unique folder on the Filesystem (eg. /images/art_01), I want to display all images within this folder and have the possibility to add (speaking, copying) new Images into this folder (there is no need to delete an Image) arranged, so it doesn't look too disgusting ;).
Since I just now the basics of Java, I qould appreciate if someone could help me, with something I can adapt directly into a JFrame - if that's possible.
Thanks ;)
With netbeans it's really easy, netbeans has a JFrame/JPanel drag&drop designer/gui builder (right click on package -> new -> JFrame form). After customizing the GUI you can make your main class extend your custom frame, or add a new custom panel to your JFrame, depending on whether you choose to make a JFrame or a JPanel.
http://netbeans.org/kb/docs/java/quickstart-gui.html some details on how to use the netbeans gui builder.
With this builder you can also add events to the different components. If you want to view a directory use JFileChooser.
