Can't mport javafx - javafx

I'm using Netbeans 8.0.2. I used the wizard to created a Java class library project so I could share a class among several projects. I now want to add some capability that requires me to import from javafx (SimpleStringProperty). Fix imports didn't work and Intellisense says it doesn't know javafx.
I looked at the Project Properties | Libraries setting of one of my JavaFX applications and I see javafx.classpath.extension. I think I need this, but I don't know how to add it. I searched and someone suggested adding the jdk's jfxrt.jar file to the compile libraries, but that didn't work.
Is the lack of javafx.classpath.extension my problem? If so, how do I add it?

I finally found this bug that addresses this: Bug 213219 .
Basically, you: "...go to Project Properties, Deployment panel, and check "Keep JavaFX Runtime on Classpath"..."
Thanks everyone!

Unable to create a JavaFX project in Netbeans IDE 16 [duplicate]

I've been banging my head on this one for ages and all of the tutorials I've found don't seem to work. When I try to create a new JavaFX project in Netbeans 14, using JDK 18 and the latest JFX download for Windows here:
https://gluonhq.com/products/javafx/
Also tried with JDK and JFX 17 and still no luck. I get this error:
I've added the libraries like so:
If I try to add the platform folder, it won't let me progress through the dialogue:
I can't find solutions to this anywhere and, again this is the same with JDK 17 and 18, and JFX 17 and 18. I've checked the documentation and there's nothing that seems to solve the issue.
It says to go to the JavaFX tab and enable JavaFX, but there's no JavaFX tab... Unless they mean this:
But if that's it then, as you can see, it's already enabled and it's still not working. I'm totally lost. I don't understand why the documentation is so poor for FX, for every IDE. It's honestly like they don't want people to use it and every tutorial I'm finding is using outdated versions of NetBeans, the JDK and JFX D-: (they also don't solve the issue even if I do follow them).
If anyone could help guide me, I'd really appreciate it.
I would suggest you go to New Project -> Java with Maven -> either Simple JavaFX Maven Archetype(Gluon) or FXML JavaFX Maven Archetype(Gluon). Use the POM to change your version of JavaFX from the default to whatever version you like. I also use the POM to change the JavaFX-Maven-Plugin to the latest version.
I strongly endorse the approach using maven suggested here. This project started exactly the same way; I'd welcome learning of any issues you encounter.
Alternatively, follow the steps outlined in JavaFX and NetBeans: Non-modular projects: IDE. You've created a JavaFX library, but "Don't try to create a JavaFX project." Instead, choose Java with Ant and Java Application to create a new project, shown below, then follow the remaining steps carefully. It's a convenient alternative for a scratch project while you assay maven.
Addendum: The ant code for a JavaFX project, not selected in the image above, may attempt to package dependencies that are no longer required. In particular, a project using module javafx.web may fail with the following error, seen here and here. The easiest fix is to recreate the Java application by choosing Java Project with Existing Sources.
Unable to create javax script engine for javascript.
Alternatively, a simple example using a custom ant script is cited here.

add module in qt(QML module) [duplicate]

So when I create a new Qt project inside Qt Creator I'm only asked for some simple details like location of the project, build targets, the main window class name (along with header, source and form file) and at the enda choice to add it to version control.
After I create the project I'm only given the qt core and gui modules. My question is how do I add other modules (such as network or opengl). I've looked and looked, yet I cannot find anything on how to add other Qt modules easily. I know I can edit the .pro file, but unfortunately I don't know all the modules in Qt, nevermind the name I'm supposed to put there. Adding external libraries is easy, but how come there's no (obvious) option to add Qt libraries?
Help would be much appreciated ^_^ Thanks!
Oh yeah... I'm running Arch Linux if that's any help.
Edit your .pro file. It should has one line like this:
QT += core gui
Append the desired modules in this line. To get the module's names, just remove the "Qt" part in this list. (e.g. QtSql turns "sql")
I can't find that either.
It seems that in older versions of the "New project" wizard you used to be able to specify which modules you wanted to use, but even then you were not able to alter your choice later. And this seems gone now, so your only choice is to manually edit the .pro file.
As others have pointed out, you simply #include the module you want in the source and add the name of the module in the .pro file to the QT variable.
However the actual documentation you need which no one else has mentioned is the qmake Project Files page. qmake is very powerful and it's well worth getting familiar with how it works and I think that's why they don't provide a complete GUI for it, as it can handle some very complex scenarios.
You have to read the documentation to add the modules.
Frankly speaking, I never really felt like that there needs to be a GUI for that.

Add DLL to ASP.NET vNext Project

My goal is to add a reference of my ASP.NET vNext to the old MySql.Data.dll. I think that this should be possible.
I put it in a NuGet package but if I compiled my project, I receive an error message.
Anything there is wrong.
Is there a guideline anywhere showing how to add DLL references? I searched a lot until now, but haven't had found anything.
I assume this is same question as the post below? If you still have questions please do let us know.

One workaround is to create a class library project with your library reference. Then use a project reference from your website to the class library project.

Customize Adobe File

I have a problem with my Flex Builder Plug-in.
I'm using the Flex Builder 3 Plug-in in my Flex application (in Eclipse).
Now I want to customize the MessageResponder.as File in the Plug-In. I found the ActionScript File without any problems, but the point is, that my changes doesn't cause anything because the file is allready compiled. (That's my guess)
Now my question:
How can I compile the file after editing it? Is there a possibility at all?
Thanks for your help!!
What you want to do is called "Monkey Patching." What you need to do is create your own version of the file in the same package location, and yours will be used in preference to the one from the swc.
The MessageResponder.as class is a file in the Flex Framework. You can modify it if you want, and--in essence--create your own version of the Flex SDK. However, you will most likely have to re-buld the entire framework for this to work. You're best bet for doing this is to get the source for the most current Apache Flex SDK; modify your class and then build the framework from scratch. After that you can use the Flash Builder "multi-SDK feature" to use your modified SDK in a Flex Project.
I'm not sure if Flex Builder 3.x supports multiple SDKs.
This may be a time consuming process. The alternative is to extend the MessageResponder and add your changes. Then you'll have to make sure that your new MessageResponder class is used instead of the old MessageResponder class. This could difficult due to many private methods used in the Flex Framework.

Flex drawing example error

I am new to flex and i am trying to run the code for flex drawing application example given at following path:
http://www.flashcomguru.com/components/flex_whiteboard/whiteboard_demo/srcview/index.html
But I get the following error at the compile time:
''Unable to locate specified base class 'Whiteboard.WhiteboardManager' for component class 'Whiteboard.Whiteboard'.''
Please someone suggest me that why it is coming and how i can overcome this.I am using Flash player version 10 and flex 3.0 sdk for the project.
Please help.
Thanks in advance.
You need to include the WhiteBoard.swc library in your project. If you're using Eclipse/Flex Builder go to project properties -> flex build path -> library path -> add swc. Or moving it to the libs folder should be enough.
The sources for the component are not included in that demo as it is not a free component. I didn't see a demo version either, so unless you buy it, you probably won't be able to run those sources locally.
Sounds to me like your source paths aren't set up correctly. Have a read of this article to see how source paths are set up
