JxBrowser HEAVYWEIGHT Dispose on WINDOW_CLOSE_REQU

Question

I'm currently playing around with the Evaluation License for JxBrowser 6.2.

I'm creating the BrowserView as follows:

Browser browser = new Browser(BrowserType.HEAVYWEIGHT);
BrowserView browser_view = new BrowserView(browser);

I'm attaching the BrowserView component as follows:

stage.setScene(new Scene(browser_view));

If the Browser is configured to operate in LIGHTWEIGHT mode, I'm able to execute:

browser_view.getBrowser().dispose();
Platform.exit();

However, if the Browser is configured to operate in HEAVYWEIGHT mode, then the application hangs when executing:

browser_view.getBrowser().dispose();

I can see in the logs that the Dispose message was written, but it appears as though the JxBrowser Chromium processes never receive/process the message.

Any ideas?

Answer 1

It looks like you need to ensure that the stage has been closed before calling dispose.

stage.close();
browser_view.getBrowser().dispose();
Platform.exit();

Answer 2

Please try calling this code asynchronously. Maybe it's just a deadlock:

Platform.runLater(new Runnable() {
    @Override
    public void run() {
        browser_view.getBrowser().dispose();
        Platform.exit();
    }
});

Answer 3

As answered before me the solution to this is to dispose the browser after the stage has been hidden (closed).
A good approach would be to put those commands on the stop() method of JavaFX Application.
So that either way you close the window (by clicking the close button or programmatically by calling Platform.exit()), the browser will dispose (and the whole application will finish and exit).

Something like that:

@Override
public void stop() throws Exception {
    stage.hide();
    browser.dispose();
}

Answer 4

As a reference, I used configuration described here link (Section: 9. Pop-up Windows).

Platform.runLater(() -> {
    browser.dispose();
});

Platform.runLater(() -> {
    stage.close();
});
