问题 This is usually done in JavaScript/ JQuery . I'd like an implementation in Java/ JavaFx. A bit more details: I have a gallery of pictures I'd like to list, first as small 32 * 32 , then when a user clicks on one of the 32 * 32 icons, a larger one of the clicked should appear on another pane.

问题 I am desperately trying to create an Image from a pixel-array with integer values. Regardless of using the WritableImage or the Canvas, it is always said that the PixelFormat is BYTE_RGB or BYTE_BGRA_PRE, so that I am forced to use a byte-array.

问题 Is it possible to create a Stage in JavaFx whose height changes dynamically? Or, in other words, is it possible to change the height of a Stage once it has been created ( stage.show() ), so that the stage morph's into its new height? 回答1: Use stage.sizeToScene() to resize the stage to whatever the current preferred size of it's root is. stage.setScene(new Scene(someContent)); stage.show(); .... stage.getScene().setRoot(someNewContent)); stage.sizeToScene(); You can also just call stage
