System notifications

Show native toast notifications with click actions, buttons and reply fields on Windows and Linux.

Show a toast from Java. It uses WinRT on Windows and the desktop's notification service on Linux. Available since 0.3.0.

From Java

app.notify(Notification.of("Export finished", "report.pdf is ready")
        .withOnClick(() -> window.focus())
        .withButton("Open", () -> open())               // up to 5 buttons
        .withReply("Send", "Reply", text -> send(text)))  // a text field: Windows only
    .thenAccept(shown -> { /* false: the system did not show it */ });

Callbacks run on the UI thread while the app runs. To skip a toast while the user is already in your window, check window.isFocused() (since 0.3.1).

Platform notes

• On Windows the first call registers your appId as the display name under HKCU\Software\Classes\AppUserModelId (nothing is installed). The future is false if the user turned notifications off.
• On Linux the future is false when there is no notification service.

From the page

To let trusted pages do it, call window.enableNotifications(app) before the page loads, then:

await jolt.notify(title, body, {
  onclick,
  buttons: [{ label, onclick }],
  reply: { label, placeholder, onreply }
});

At most 5 notifications per 10 seconds per window.
