Hi everyone,
as promised, here is the source code of the demo you asked for!
I hope it is useful for you to learn and experiment. Let me know what you think! What do you like? What would you do differently? Post your improvements and suggestions here on the forum.

Suggestion: commit a Gradle wrapper to the repo, so that potential users don’t have to install Gradle in order to run the app.

capdevon · May 22, 2022, 4:48pm

ok, I will do it asap

Edit:
Done, let me know if everything works.

This is a general problem with the way Unix does work permissions. I’m trying to figure out how to do what you ask me in Windows. Could you send me a PR please by editing the file with the permissions chmod = + x gradlew?

sgold · May 22, 2022, 6:28pm

I’ll send you a PR ASAP.

capdevon · May 22, 2022, 6:29pm

Thanks

I still need build instructions, however…

OpenJfx requires a module info to include the jfx modules for the package, make sure you have module-info.java at src/main :

module hellofx {
    requires javafx.controls;
    
    exports mainPackage;
}

If you don’t want to use java modules then you need to specify a mainClassName explicitly, i think, those are the openjfx samples :

The non-modular :

github.com

openjfx/samples/blob/f44ca19e4178ee01663d7a2ae8a5da8e58eee1fa/CommandLine/Non-modular/Gradle/hellofx/build.gradle#L22


      
          //    runtimeOnly "org.openjfx:javafx-graphics:$javafx.version:win"
          //    runtimeOnly "org.openjfx:javafx-graphics:$javafx.version:linux"
          //    runtimeOnly "org.openjfx:javafx-graphics:$javafx.version:mac"
          }
          
          javafx {
              version = "16"
              modules = [ 'javafx.controls' ]
          }
          
          mainClassName = 'hellofx.HelloFX'
          
          jar {
              manifest {
                  attributes 'Main-Class': 'hellofx.Launcher'
              }
              from {
                  configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
              }
          }

The modular :

github.com

openjfx/samples/blob/f44ca19e4178ee01663d7a2ae8a5da8e58eee1fa/CommandLine/Modular/Gradle/hellofx/build.gradle#L16


      
          
          repositories {
              mavenCentral()
          }
          
          javafx {
              version = "16"
              modules = [ 'javafx.controls' ]
          }
          
          mainClassName = "$moduleName/hellofx.HelloFX"
          
          
          jlink {
              options = ['--strip-debug', '--compress', '2', '--no-header-files', '--no-man-pages']
              launcher {
                  name = 'hellofx'
              }
          }

EDIT:
I added a PR that will fix this problem and another one for readme .

Pavl_G · May 24, 2022, 12:09am

@capdevon I will do a PR, if you don’t mind with building…and how to build…

EDIT :
BTW, to run a java11+ app, you must use gradle7.0+ wrapper, i will make sure to update this, no worry.

I got an exception running on lwjgl-2 :

However, the project runs fine on lwjgl-3…anyone knows why ?? Seems incompatibility of native binaries, not sure, last time i was running jme3-lwjgl-3.3.2 fine w/o problems…

EDIT: or just the jdk !!

EDIT2: just ignore this for now, i will investigate into it later, isn’t related to your project…

Thank you so much for your contributions guys. Sorry if I answer late, unfortunately these days I don’t have much free time. If you both agree on the solution, I accept the PR software changes. I apologize for the inconvenience, but there are some technical aspects of ‘gradle’ that I still don’t know well.
