JFXPanel (original) (raw)

I'm pretty sure I do this without any issues. Assuming the app is Using JFXPanel in the first place. Trying to start Swing from a "pure" FX app didn't work for me. I had to make sure I started the FX Platform thread after Swing/AWT was initialized.

Is it possible to run a JOptionPane from the FXApplicationThread with SwingUtilities.invokeAndWait()?

I tried it and it hangs in CCursorManager.nativeGetCursorPosition() (which I've seen before when I've accidentally run swing code from the FXApplication thread). jeff On Dec 14, 2012, at 10:19 AM, Werner Lehmann <lehmann at media-interactive.de> wrote:

Scott,

JFXPanel has quite a few issues (look for JFXPanel or Swing in Jira). Among those is the filechooser problem. It is probably just one instance of the problem that a JavaFX stage cannot be modal or on top of Swing windows. To work around this we have to put JFXPanels in JDialogs. Not really sexy: apart from the overhead in code we know today that we have to touch this again one day to convert the JDialog to a stage. Regarding your problem of how to get from a node to the JFXPanel: no idea why you would want to do this. I have a dozen jfxpanels but never needed such a thing. I guess you could extend JFXPanel and add a reference to the fxpanel to some userdata on a node, or something like that.

In order to work around some of them I am wondering if it is possible to get a reference to the JFXPanel if all I have is a Node? I can get the Scene's Window, an "Embedded" Window that seems to be the root of a lot of problems with popups and dialogs. That seems to be enough to determine that the Node is hosted by a JFXPanel, but can I actually get the JFXPanel instance?

If there is a way via public APIs that don't rely on me peaking at implementation details like com.sun.javafx.stage.EmbeddedWindow? Along this line… why is it that things like the FileChooser and other JavaFX dialogs don't respect the window ordering when used from a JFXPanel? They easily flip behind the parent JFrame. I would have thought that the correct Window hierarchy in native land could still include the native window of the JFrame and that should prevent such things. Scott
