问题 I noticed that when I run JavaFX application on JVM 7 and JVM 8 I get different default skins. How I can set the default skin to be same on every JVM? 回答1: You can set the default skin: @Override public void start(Stage stage) throws Exception { .... setUserAgentStylesheet(STYLESHEET_CASPIAN); .... } http://fxexperience.com/2013/01/modena-new-theme-for-javafx-8/ 回答2: The default stylesheet for JavaFX 2 is caspian.css. You can find it in jfxrt.jar under com.sun.javafx.scene.control.skin

问题 Since I am using JavaFX 8, all my textarea s do not apply the transparency that has been defined in the corresponding css. It works fine in Java 7, but for the release candidate of JavaFX 8, I can't get it to behave like before. EDIT: This question is about JavaFX TextArea, not a JTextArea. -fx-background-color: rgba(53,89,119,0.2); does not have any effect on the textarea anymore, although it should have an alpha value of 0.2, but it is opague... Is that a known issue? 回答1: The TextArea

No matter what i try menu item inside menu-button remains unchanged. .menu-button { -fx-background-color:black; } .menu-button .label { -fx-background-color:black; } Now how can i change color that is left out?? 回答1: MenuButton uses Menu internally and has a similar API. In such way that MenuButton contains MenuItem s list just like Menu . So I think you need to try to play with .menu , .menu

问题 I tried to make a plane in JavaFX application using official tutorial and has the next code: Image diifuseMap = new Image(getClass().getResource("t.jpg").toExternalForm()); TriangleMesh planeMesh = new TriangleMesh(); float[] points = { -5, 5, 0, -5, -5, 0, 5, 5, 0, 5, -5, 0 }; float[] texCoords = { 0, 0, 0, 1, 1, 0, 1, 1 }; int[] faces = { 0, 0, 1, 1, 2, 2, 2, 2, 3, 3, 1, 1 }; planeMesh.getPoints().addAll(points); planeMesh.getTexCoords().addAll(texCoords); planeMesh.getFaces().addAll(faces)

问题 In JavaFX, how can I display values which continuously change with time using "label" ? 回答1: There are numerous ways to achieve that, the most convenient would be to use JavaFX's DataBinding mechanism: // assuming you have defined a StringProperty called "valueProperty" Label myLabel = new Label("Start"); myLabel.textProperty().bind(valueProperty); This way, every time your valueProperty gets changed by calling it's set method, the label's text is updated. 回答2: How about using
