I have a modular JavaFX application. It perfectly loads all stylesheets when I run it using the IDE IntelliJ.
However, when I publish the application as PKG for Mac platform and try to run, no CSS is applied to the application. The PKG file successfully installs the JavaFX application on Mac but no stylesheet is loaded.
The app run as expected but without any css applied.
I am using openJDK-15.0.2 and generating the PKG file using jpackage.
Folder Structure:
Folder structure
To get the resources:
Class clazz = SocketClientFX.class;
Scene scene = new Scene(root);
scene.getStylesheets().add(clazz.getResource("/styles/Styles.css").toString());
I solved this problem by adding "opens" in module-info.java for each resource folder.
For example:
opens styles.common;
opens jsonFiles;
opens images.common;
opens styles.stevePane;
etc...
In the code, each resource is accessed as follows:
containerBorderPane.getStylesheets().add("/styles/stevePane/loadingWindow.css");
Then I built the project again and create a new PKG file. When I installed and run it again, all resources including the CSS files were loaded.
When the resource is accessed via getResource(), as below, we do not need to add opens directive in the module-info.java.
scene.getStylesheets().add(clazz.getResource("/styles/Styles.css").toString());
Thank you, #James_D and #Slaw, for your comments.

I recently finished my first JavaFX project and am ready for deployment. I found that when I create the jar file for my project my ide creates a folder with the jar and other necessary files. I noticed that when I run the jar in the file everything works fine. However, when I take the jar our of that folder and place it as a desktop icon, various resources no longer become available - I am assuming this is because the jar file and the various resource files are no longer in the same file path/folder. - Is this the correct assumption to make?
Regardless, I wanted to ask what is the standard method of getting JavaFX resources and the accompanying jar file to work when the resources are not located in the same folder?
Essentially, I want to have a clickable desktop icon that launches the app, which the jar file fulfills. But if I put that jar file in a folder with its resources to get the project to work properly then the user will have to press the folder and then the jar file in order to get the project to launch - which is very counterintuitive.
Any ideas on how this issue is handled?
The best way to do this is to create a shortcut to your jar file not copy it to another location. The jar file depends on these resources to execute especially if you used external libraries.
The other alternative would be to export your jar file with the libraries included in the jar. This however would make your jar very huge depending on the number of libraries you have.
I hope this helps.
I have copied a new .java file in relevant src folder. But, it doesn't appear in project explorer in STS4. No option in IDE to import file.
I know this is such a simple thing. Should have obvious options there. However I am not getting clue.
Press F5 or execute the menu item Refresh on the project once you have added a file to the project from outside the IDE, like on the file system directly.
I finished writing a little tornadofx app in IntelliJ CE and now want to export it as a single file which can be downloaded and launched by users. For now it would be sufficient to provide a single jar file. But it would be also great to know on how to export a self contained installer for OSX, Windows and Linux. Unfortunately I don't know how to do any of that. Can you help?
Have a look at the FxLauncher project, which is also from the creator of tornadoFX. FXLauncher allows you to easily distribute your javafx/tornadoFX application. The project provides a maven-plugin which allows you to generate a self containing javafx/tornadoFX application that you then publish to a web-server or common directory (e.g an internal app in your company network). After that you can generate native installers for Linux, OSX and Windows. The installer itself will only install a small app, which will know the location of your web-serve or directory. On startup it will download the latest deployed version of you application and run it.

Customizing update ui
In case you want a single jar file, you can export it as a regular Java program (not the JavaFX option in IntelliJ). You do this by creating and building an artifact.
Go to the Project Structure window, and from there select Artifacts
Click the "+" icon to create a new artifact, and select JAR > From modules with dependencies...
Select the main class and press OK
And that's it, the artifact has been set up, now, to generate jar file, just go to Build > Build Artifacts menu, and select the newly-made artifact, and the IntelliJ will generate the jar file in the "out" directory.
Not sure if this is the best solution, but it's what I've been using, and it works for me.
I'm using libgdx for a desktop game/prototype and I want to start getting into UI design.
I followed the answer here: Default Skin LibGDX? to download the necessary skin files but I'm not sure where in my project to put the ui directory with these files. I have tried to put it right in the project directory along side libs and src, so there's libs, src, ui, Referenced Libraries, and JRE System Library but when I reference the Skin with new Skin("ui/uiskin.json") it is throwing a filenotfound exception. Should this be down in my com. package in the project viewer in Eclipse?
I understand for an Android app you use the asset folder, but I don't have one in my project since it's a desktop app, even if I were to just add it.. I still don't know at which level unfortunately. This is probably really simple.
Thanks in advance.
The skin files are being looked up as "internal" files. On Android, this will look through the Android asset directory and CLASSPATH, but with the Desktop backend, only CLASSPATH will be searched.
To be consistent with the way things generally work in Libgdx, create a directory called assets next to the src and libs directories in your desktop project. Then put your ui directory inside assets. This isn't strictly necessary (see below) but will make your project a bit more compatible with other Libgdx code and projects. With an Android project the desktop assets directory is normally linked to the Android assets directory, but without an Android project you should create a regular directory.
If you used the Libgdx Libgdx "setup tool" the desktop project's assets directory should already be on the CLASSPATH. If not, you will also need to add this assets directory to your CLASSPATH: Right click on the project -> Properties -> Java Build Path -> Source tab -> Add Folder ... -> Select the assets directory.
To be clear, if you don't want to mirror the Libgdx conventions above, you just need to make sure the directory containing your skin files is on the CLASSPATH, then they will be found as "internal" Libgdx files (for example, you could add the ui directory directly to the CLASSPATH, and then look the files up without the explicit ui/ prefix).
I have wrote a Qt Quick Desktop application in c++ qnd Qt Creator(QML) on Windows7. Now I have to deploy it.
I'm using Qt Quick Desktop Components plugin in my application, I've installed it according to these instructions, and I'm using it with:"import Qt.labs.components", as written there.
I tried adding to the .pro file:
QML_IMPORT_PATH = C:\QtSDK\Desktop\Qt\4.7.4\mingw\imports\Qt\labs\components
but I saw it's working well without it, and I removed it.
I've read a guide how to deploy such an application here, and followed it; I have now a deployment folder, with: the .exe file, the needed dll's, and a folder hierarchy like:Qt/labs/components.
in components I put the styleplugin.dll(for desktop components), and a qmldir file, with the content: plugin styleplugin, excactly like in the doc.
but when I'm runnig my application.exe from the deployment folder in another computer, I'm getting a white, empty window, means: It didn't find the .dll file.
Should you explain me please what's wrong?
I know two reasons, when app can not load plugin dll:
Some of dependecies of the plugin dll are missing or can not be found and that is why it can not be loaded. Qt Creator or Visual Studio environment can be different than the system one. For example, your IDE can modify PATH environment variable. Check plugin's dependencies availability with Microsoft Dependency Walker tool in the same environment where you launch your app.
App can not find plugin in standard directories. To check this you should specify plugin import directory explicitly:
QDeclarativeView *rootView = new QDeclarativeView()
rootView->engine()->addImportPath(QLatin1String("path/to/your/imports"));
