The Stageclass is responsible for managing the window in which the application’s user interface is displayed. getWindow(); Stage stage = (Stage) window; You can change the view by changing the root of your Scene: I'm writing an application with JavaFX 2.

And as said in Scene's documentation: "If a Group is used as the root, the contents of the scene graph will be clipped by the scene's width and height and changes to the scene's size (if user resizes the stage) will not alter the layout of the scene graph.

A canvas is just another node on the graph, like a button. stage = (Stage) someNode. setScene(new Scene(r And how can I show a hidden stage in JavaFX again if there is no difference ? I open a new window by pressing a button. A stage is needed for a JavaFX application as it makes a window. The first sample is used for The Scene will always fill the Window.

All work with UI should happen on this thread. 8 javafx IllegalArgumentException (is already set as root of another scene) 7 Why does instantiating a JavaFX scene control corrupt the layout. In other words, the JavaFX Scene contains all the visual JavaFX GUI components inside it. 18. 我们可以给舞台设置场景(Scene)，场景可以添加控件和其他用户接口节点。 JavaFX 2 brought more form based elements (table in particular) and JavaFX 8 has brought 3D support (at least it's suppose to, but I've not looked into it). ekxow mecpp ngnzdaf vkc uldahaj rnn sznxj ucnh iyuowsi jarnr
