enterNestedEventLoop as public API?

Hi List,
Any chance that Toolkit.getToolkit().enterNestedEventLoop() will in the
future become public API?
I'm currently using this to create Dialogs based on a Pane to avoid
creating Stages (which have the nice show and showAndWait
functionality). I duplicated this functionality in a Pane, allowing me
to create Dialogs on top of existing Scenes without creating a Stage,
and it makes use of the enterNestedEventLoop and exitNestedEventLoop
functions in com.sun.javafx.tk.Toolkit.
The reason I'm avoiding the Stages is because they donot play well with
an application that never has the mouse or keyboard focus (my
application is fully remote controlled) -- creating a Stage, even one to
just show a Dialog, will cause Windows to try and attract the user's
attention by flashing its taskbar button (for which I filed a
bug/feature request) and this is undesired.
Regards,
John
(Here's a part of the DialogPane to show and close it:)
public R showDialog(Scene scene, boolean synchronous) {
this.synchronous = synchronous;
this.scene = scene;
this.oldFocusOwner = scene.getFocusOwner();
Parent root = scene.getRoot();
stackPane.getChildren().add(root);
stackPane.getChildren().add(this);
scene.setRoot(stackPane);
requestFocus();
if(synchronous) {
return (R)Toolkit.getToolkit().enterNestedEventLoop(this);
}
return null;
}
public void close() {
Parent originalRoot = (Parent)stackPane.getChildren().remove(0);
scene.setRoot(originalRoot);
scene = null;
if(oldFocusOwner != null) {
oldFocusOwner.requestFocus();
}
if(synchronous) {
Toolkit.getToolkit().exitNestedEventLoop(this, getResult());
}
}
