I am writing a JavaFX application that contains a Java Swing GUI panel (it's the OpenBlocks workspace to be specific).
I want to detect certain events that occur in the Java Swing panel from the JavaFX side and respond to them. I have an event listener in the JavaFX environment, and when that listener "hears" an event, I want to make some JavaFX GUI object visible, so I was thinking of trying to bind the "visible" property of these objects to some variable Java variable that will update when the events of interest occur; but I tried to do this binding, and it is not working for me.
So my general question is: Is there a way to bind a JavaFX variable to a Java variable/object, and if so, how is this done?
Thank you in advance for any help on this!!! :)
In JavaFX 2.0 you can do this the javafx.beans.binding.ObjectProperty<T> (and related) classes.

I am currently working on a self-project using Java SE-13 on Eclipse with Window builder.
I intend to create a program that has the following design flow using individual button as the event-source.
[Edit](for those who do not wish to visit the link)
Default Package Swing application <---> Package A swing application
I using package to help me simulate then I am using people program and integrate it. Trying to think of modular and keeping the project organize
[/Edit]
I had tried to use the following two approach.
Destroy the "current Swing application"(extend Frame) using
XXX.dispose(), create the instance of the second Swing application
and set it visible.
It works fine if the flow is one direction but not bidirectional. When I try to return back to the "current Swing application" it was unable to destroy the second-swing application which it throws a Nullpointer exception.
Using CardLayout. By creating multiple Jpanel and only set the one I wish to display as visible(true).
It allows me to have the bi-direction flow. But I am not using packages.
I had heard about the getContentpane() method but I am unsure if it will meet my requirement or it the best practice. If so, how will you be implementing else if not, what will you do to achieve my desire flow.
Thank you and take care
I'm looking for a program, application, or some way to examine a java application, and be able to view its GUI information. This would include buttons, labels, panels, and list information. Ideally you could examine things by using the mouse pointer, and either hovering over an object or clicking on it. The separate program or application could display things like type of object, object name, and position of object in a console or a window.
I've found some applications that can examine a java application if it's using the Java Access Bridge, but I'm looking for a way that does not require the target java application to have the JAB.
Java Native Interface (JNI) allows you to get mouse clicks, positioning, and keyboard presses, but it does not appear to return information, like button names, inside a java application. Any ideas?
Answers to this question will be highly subjective, depending on the type of GUI technology used and the personal views of the answering person.
That being said, when I do JavaFX development, I use ScenicView. It works really well in my experience and can be loaded a number of different ways. It has most of the features you mentioned and displays a ton of data about the GUI objects, as well as highlighting the selected object's boundaries.
I want to make all Windows open in a Java swing application sharing same language InputMethod, that is, changing InputMethod in one window will result InputMethod changing in every other Window.
I have tried to create a single global InputContext and override getInputContext() of each window to return that Context, but it's not working reliably for some language input methods. Any idea?
I am working with JFrame and observers. I have a functioning GUI with multiple buttons and functions.
I am trying to create a button which opens a new window, that is exactly the same as the main window. All changes in any window, should be automatically updated to all open windows.
Any help how to begin?
General suggestions:
Use Model-View-Control or MVC design pattern,
use a factory method to create your sub-views (or as you call them, windows), createWindow(Model model), and
give each sub-view the same shared model object.
If I have Java program and I need to alter it to an interface and include icons,
is there any easy I can do this and is there a good application that can help me to do it ?
or do I have to code it in myself?
Nop, /me thinks ur need 1337 mad Java programin' skillz!
Translation for the rest of the world: Sorry, you'll need to program in Java.
Added: Hey, what's with the downvotes? He started it! :P Besides - no matter if he wants to add or modify (the original text wasn't clear on this) the UI of a Java program, he will need to program in Java to bring his UI together with the code. There is no miracle tool that can allow you to draw an UI and it will suddenly do what you do.
Netbeans has a Swing GUI Builder. Quoting from their website. Let's hope this doesn't count has hidden advertising :)
Design Swing GUIs by dragging and
positioning GUI components from a
palette onto a canvas. The GUI builder
automatically takes care of the
correct spacing and alignment. Click
into JLabels, JButtons, ButtonGroups,
JTrees, JTextFields, ComboBoxes and
edit their properties directly in
place. You can use the GUI builder to
prototype GUIs right in front of
customers.
If you want to add a UI to your Java program there are tools to help you, such as the Swing GUI Builder inside of IntelliJ Idea. However, you're still going to have to write the appropriate code to hook into the UI.
It's just a website? Well depending on whether it uses CSS you might be able to just modify a .css file. This will only let you modify how the site looks as opposed to works.
See here for an example of how this technology works. However this depends on how css-dependent the website is and it's possible you may still run into some difficulties.
You want to use a Java framework to help you with the UI. For example, you can use JSF (Javaserver faces), which allows you to drag and drop components for a UI onto the site. Otherwise, you can use web programs such as Dreamweaver to design the UI, before coding the backend logic yourself in java.
