Your TODO List

Install VS Code extension for better JavaFx CSS Support

• There is an extension for better JavaFx CSS support in vscode-extension folder
• You can install that with this command on your IntelliJ terminal:

code --install-extension "vscode-extension\css-helper-for-javafx-1.0.1.vsix"

• (Optional) Also after that open your VS Code press CTRL+SHIFT+P, enter user settings, open settings.json and finally add this line there:

"css.lint.vendorPrefix": "ignore",

Main.java

• Load the FXML file using FXMLLoader
• Create a Scene, set its title, attach CSS file to it, and show it on the Stage

Controller.java

• Wire up the "Shop" buttons → show payment alerts
• Implement theme toggle (Dark ↔ Light)

Learning Goals

By working through this workshop, you'll be able to:

• Understand the structure of a JavaFX Maven project
• Read and write basic FXML layouts
• Connect your visual design (FXML) to Java code (Controllers)
• Handle UI events with @FXML methods
• Switch CSS themes dynamically
• Create and show JavaFX dialogs

Notes

Always run your Javafx app from the Launcher.java, Launching from the Main.class (where you have extended from Jfx Application) sometimes doesn't work due to building issues, and you get error of not finding Javafx.

Don't forget to set your jdk in the Project Structure > SDK !
