FAQPage Schema

How do I bridge Swing and Compose state changes in IntelliJ plugins?▼

To bridge Swing and Compose state changes in IntelliJ plugins, use MutableSharedFlow for cross-thread communication. This ensures safe state bridging between the Swing EDT and Compose runtime without causing recomposition races.

How does Jewel theming trigger Compose recomposition in an IDE?▼

Jewel theming triggers Compose recomposition by synchronizing UIManager and LafManager updates. When the Look and Feel changes, LafManager initiates recomposition to ensure the Compose UI reflects the updated theme.

What is the best way to mount Compose panels inside Swing editor tabs?▼

The best way to mount Compose panels inside Swing editor tabs is lazy mounting. Deferring panel mounting avoids initialization-time costs and prevents editor restoration issues within IntelliJ plugin environments.

Why do I get recomposition races when mixing Swing EDT and Compose?▼

Recomposition races occur when mixing Swing EDT and Compose due to unsafe cross-thread state updates. Using MutableSharedFlow to bridge state changes provides a stable channel that prevents these synchronization conflicts.

Does Compose interop work with IntelliJ's UIManager for Look and Feel updates?▼

Yes, Compose interop works with UIManager for Look and Feel updates. The bridge uses UIManager-based theming combined with LafManager to actively trigger Compose recomposition when the IDE theme changes.
