如何创建JavaFX对话框？

Question

I need to create a dialog in JavaFX. I know that I can make the Stage behave like a dialog by modifying modal, owner and resizable properties.

But how do I hide the "minimize" and "maximize" buttons from the Stage window? Typical dialogs only have the "close" button.

Answer 1

Under Windows 7, initializing to StageStyle.UTILITY before you show the window will create a window with only a close button and no minimize or maximize button:

Stage dialog = new Stage();
dialog.initStyle(StageStyle.UTILITY);
Scene scene = new Scene(new Group(new Text(25, 25, "Hello World!")));
dialog.setScene(scene);
dialog.show();

If you would like a complete set of basic JavaFX dialogs I would recommend the JavaFX UI sandbox dialogs .

The JavaFX UI Sandbox was not created by me and is not hosted on my site (source is hosted by Oracle). I requested Oracle to document the sandbox dialog API . If you like, you may vote for or comment on the request.

Makery's blog has some minimal 3rd party documentation of the sandbox dialogs, including basic usage examples as well as a backport of the dialog portion to JavaFX 2.2.

Update

The JavaFX UI Sandbox has been superseded by the ControlsFX project .

Update

Java 8u40 will include JavaFX dialogs built into the core platform APIs. You can try an early access release of Java8u40 . The relevant class is javafx.scene.control.Dialog and it's related subclasses such as javafx.scene.control.Alert (the Alert class is for showing standard dialogs which are similar to Swing's JOptionPane class - so you don't need to use JOptionPane to get out of the box standard dialog functionality).

Makery wrote a new blog tutorial for dialog functionality provided in Java 8u40 .

You can also try my approach to the custom dialog window for Java FX 8. Both: source code with practical use example, and runnable demo are available in the link below:
