Install the JavaFX library.\n\n3. Run the sketch snippet; the output will show that the JavaFX modules are not in the classpath.\n\n### snippet\n\n``` processing\nimport processing.javafx.*;\n\nString classPaths = System.getProperty(\"java.class.path\");\n\nprintln(classPaths);\nprintln();\n\nString [] path = classPaths.split(\";\"); \nprintArray(path);\n```\n\n### Additional context\n\nA search for JavaFX related issues in these repositories will provide some history and context:\n\nhttps://github.com/processing/processing4\nhttps://github.com/processing/processing4-javafx\n\nRelated discussion on Processing discourse:\n\nhttps://discourse.processing.org/t/processing-and-javafx/45692/16\n\nI had some success modifying the Processing source code and adding the modules to the classpath during a collaborative session with Google Gemini.\nI can share the details on request.\n\n### Would you like to work on the issue?\n\nNo, I’m just reporting the issue","author":{"url":"https://github.com/glvjr","@type":"Person","name":"glvjr"},"datePublished":"2025-11-24T22:12:20.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/1344/processing4/issues/1344"}
