问题
I mean that when using a stage with stageStyle.UTILITY, I don't want to show the "solid white background " but a transparent background.
I need a stage doesn't shown on the windows' task bar below(stageStyle.UTILITY can satisfy), and I need a transparent background(StageStyle.TRANSPARENT can satisfy)so that I can define the close button style of my stage.
But it seems strange that stageStyle.UTILITY or StageStyle.TRANSPARENT only fit one of my request.
Thank you.

Already OK! Also invoke dialogStage.initOwner(parentStage) http://docs.oracle.com/javafx/2/api/javafx/stage/Stage.html#initOwner%28javafx.stage.Window%29
回答2:
something thus?

has an effect on the background
leads code
dialog.initModality(Modality.WINDOW_MODAL);
回答3:
It is not yet possible in javafx but javafx is swing compatible so you can use swing to make a swing equivalent to a transparent utility stage. See here for some examples. I hope that this helps.

final Stage stage = new Stage(StageStyle.TRANSPARENT);
Group rootGroup = new Group();
Scene scene = new Scene(rootGroup, 339, 319, Color.TRANSPARENT);
stage.setScene(scene);
stage.centerOnScreen();
stage.show();

Look here How can I remove my javafx program from the taskbar
just add (to move it out of sight)
primaryStage.setX(Double.MAX_VALUE);
primaryStage.setY(Double.MAX_VALUE);
and replace
mainStage.initStyle(StageStyle.UNDECORATED);
with
mainStage.initStyle(StageStyle.TRANSPARENT);
