How to disable mnemonic for JavaFX MenuBar?

阅读更多关于 How to disable mnemonic for JavaFX MenuBar?

问题 In my stage I have inserted a menubar at the top like usual for programs. I want to give the ALT key (together with arrow keys) some logic in another context within the stage. But everytime I press ALT and arrows I unintentionally navigate through the menus of the menubar, too. I want to avoid that or better completely disable this mnemonic behavior. Setting the mnemonicParsing properties of all menus to false failed. I also tried this approach without success: menubar.addEventFilter(KeyEvent

How to force anti-aliasing in JavaFX fonts?

问题 While testing the GUI of my JavaFX 8 application, I noticed that some labels are not displaying anti-aliased text. After some googling and struggling, I found out a very annoying thing that is happening. The anti-aliasing is being applied only on labels which font size is greater than 80px. Here is an example comparing JavaFX and Swing applications with AA applied: Sample code: https://gist.github.com/anonymous/be60bb89181376ff12aa Is there a way to force the AA in all font sizes? Does this

Java9模块化指南

阅读更多关于 Java9模块化指南

1. 概述 Java9在包之上引入了一个新的抽象级别，正式称为Java平台模块系统（JPMS），简称“模块”。在本文中，我们将介绍新系统并讨论其各个方面。 2. 什么是模块？首先，我们需要先了解模块是什么，然后才能了解如何使用它们。模块是一组密切相关的包和资源以及一个新的模块描述符文件。换句话说，它是一个“Java包的包”的抽象，允许我们使代码更加可重用。 2.1 Packages 模块中的包与我们自Java诞生以来一直使用的Java包是相同的。当我们创建一个模块时，我们将代码内部组织在包中，就像我们以前对任何其他项目所做的那样。除了组织我们的代码外，还使用包来确定哪些代码可以在模块外部公开访问。我们将在本文后面花更多的时间讨论这个问题。 2.2 Resources 每个模块负责其资源，如媒体或配置文件。以前，我们将所有资源放在项目的根级别，并手动管理属于应用程序不同部分的资源。通过模块，我们可以将所需的图像和XML文件与需要的模块一起发送，从而使我们的项目更易于管理。 2.3 模块描述符创建模块时，我们会包含一个描述符文件，该文件定义了新模块的几个方面： Name–我们模块的名称依赖项–此模块依赖的其他模块的列表公共包–我们希望从模块外部访问的所有包的列表提供的服务–我们可以提供其他模块可以使用的服务实现已使用的服务

问题 I have a new pc, I have installed inteliJ with JDK and JRE 9.0.1. I also installed SceneBuilder 9.0.1. I have copied the project that I had on old pc and when I run it I get this error: Error:(3, 26) java: package javafx.application does not exist. Do I need to install something else that contains this package? Thank you. 回答1: The JavaFX package is not included in JDK 9 and later. You need to install JDK 8, or you can add the JavaFX package separately, for example, from JDK 8 ( jfxrt.jar ).

Why does some nodes have a x and y position and others not

阅读更多关于 Why does some nodes have a x and y position and others not

问题 I'm trying to understand the coordinate system of JavaFX. For some nodes (shapes?) like Line or Rectangle I can (or should) specify a x and y value in the coordinate system. What exactly is this? Is this a translation and stretch which is later appended to the node or something else? Other nodes only have a setLayoutX() method, whereas e.g. the Line has both setLayoutX() as well as setStartX() . Thanks! 回答1: Every Node has two different bounds properties (ignoring Node#layoutBounds) relating

JavaFX - Bind stage size to the root node's preferred size

问题 I would like to automatically adjust the width/height of a javafx.stage.Stage whenever the preferred width/height of the Scene 's root node changes. It's a small utility window (not resizable by the user) that contains multiple javafx.scene.control.TitledPane s and the window's height should increase when one of these TitledPanes is expanded (otherwise the TitlePane's content may be out of bounds). Unfortunately I could only find javafx.stage.Window.sizeToScene() , which initially sets the
