@Ruckus Can you use type-safe css with Scene Builder? I tried a type safe class and an FXML file that referenced the companion object style but it didn't take effect.

@edvin I'm getting a strange error when I try to import a css file Exception in Application constructor Exception in thread "main" java.lang.NoSuchMethodException: bkcourse.app.BKCourseApp.main([Ljava.lang.String;) at java.lang.Class.getMethod(Class.java:1786) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:126) This is the class class BKCourseApp : App(MainView::class) { val api: Rest by inject() init { api.baseURI = "http://localhost:8080/bkcoursews/api" line? importStylesheet("/bkcourse.css") } }

When I comment the importStylesheet() call, the program runs without error

@carlw It might be possible to use type safe css with scene builder, if you have tornadofx.jar on the classpath, but you'd need to instantiate a Stylesheet somehow. That would take care of installing the custom url handler needed to locate the stylesheet. I might be able to create some special support for scene builder...

@carlw Can you try to call importStylesheet in a try/catch block? Seems like it's throwing an error somehow.

@edvin sry. I meant fxml rather than scene builder

@carlw So you want to have a stylesheet that is only loaded with the fxml file, not globally with the application?

@carlw You should be able to use the url

<css://package.className>

@carlw About the exception, I think it just can't find the stylesheet at /bkcourse.css. Can you confirm that it is in fact at the root of your classpath?

I'll try to create a better error message when it can't find the stylesheet.

@carlw If you try with 1.5.9-SNAPSHOT you should now get a warning log message instead of the error when you try to import a stylesheet that can't be found.

@edvin I'll try this in a few minutes. I used a few different paths including the one that typically works in non-tornadofx programs

@carlw The path needs to be an absolute classpath link. In a maven app that means that bkcourse.css should be in

src/main/resources/bkcourse.css

@edvin same with gradle? I'm running this through an IntelliJ application target with the gradle module as the classpath

@carlw Yeah, Gradle uses the same default layout, right? Check that the css-file is in the target/classes (or build/classes, don't remember where Gradle puts it, I'm a Maven guy :)

@edvin Here's the error message with a try / catch in the init of the App java.lang.NullPointerException at tornadofx.FXKt.importStylesheet(FX.kt:204) at bkcourse.app.BKCourseApp.<init>(MainView.kt:86) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at com.sun.javafx.application.LauncherImpl.lambda$launchApplication1$161(LauncherImpl.java:819) at com.sun.javafx.application.PlatformImpl.lambda$runAndWait$175(PlatformImpl.java:326) at com.sun.javafx.application.PlatformImpl.lambda$null$173(PlatformImpl.java:295) at java.security.AccessController.doPrivileged(Native Method) at com.sun.javafx.application.PlatformImpl.lambda$runLater$174(PlatformImpl.java:294) at com.sun.glass.ui.InvokeLaterDispatcher$Future.run(InvokeLaterDispatcher.java:95) at com.sun.glass.ui.gtk.GtkApplication._runLoop(Native Method) at com.sun.glass.ui.gtk.GtkApplication.lambda$null$49(GtkApplication.java:139) at java.lang.Thread.run(Thread.java:745)

@carlw Yeah, then the file is just not at / on your classpath

@carlw I've added a logging message instead of it throwing an exception in 1.5.9-SNAPSHOT. Do a find . in the build folder, and you'll see that the css-file is not at the root of your classpath 🙂

Can I see the project?

Do you have a bitbucket account?

I think so..

I've tried quite a few paths...Could it be that it's not finding the stylesheet relative to FK.kt?

You need to use a full class path reference, starting with /.

I added a Bitbucket account to contribute to ControlsFX it seems 🙂

@edvin If i put bkcourse.css in a folder tornadofx and use this importStylesheet, it works

importStylesheet("/tornadofx/bkcourse.css")

Seems to be using the framework classloader instead of the app's

Can I see the project?

That should be the same classloader? 🙂
