NetBeans 如何实现启动画面功能有效吗?
NetBeans 新手,刚刚注意到在文件>>中项目属性>> “应用程序”对话框中有一个标记为“启动画面”的文本字段,允许您指定程序启动时要显示的图像的路径。
我想自定义启动屏幕的工作方式(添加进度条等),并且想从头开始编写代码,但不知道从哪里开始。基于 Java/Swing 的启动屏幕的最佳实践是什么?
感谢您的任何意见!
New to NetBeans and just noticed that in the File >> Project Properties >> Application dialog there is a text field labeled Splash Screen that allows you to specify a path to an image that you would like displayed when your program is launching.
I want to customize the way my splash screen works (adding a progress bar, etc.) and would like to code it from the ground up but don't know where to start. What are the best practices for Java/Swing-based splash screens?
Thanks for any and all input!

项目属性->应用->启动画面允许您将图像添加到应用程序。此属性在
MANIFEST.MF
中设置一个名为SplashScreen-Image:
的值,例如SplashScreen-Image: META-INF/GlassFish316x159.jpg
此属性将自动使图像显示为闪屏。它在 NetBeans 内部不起作用,必须在 IDE 外部运行。有一个教程启动屏幕初学者教程详细介绍了如何使用它。本教程是针对 NetBeans 6.8 完成的,但也适用于撰写本文时最新的 7.2.1。
The project properties -> Application -> Splash Screen allows you to add an image to an application. This property sets a value in the
MANIFEST.MF
calledSplashScreen-Image:
e.g.SplashScreen-Image: META-INF/GlassFish316x159.jpg
This property will automatically cause the image to display as a splash screen. It does not work inside NetBeans, and must be run outside the IDE.There is a tutorial Splash Screen Beginner Tutorial that details how to use it more detail. The tutorial was done for NetBeans 6.8, but will work on 7.2.1 which is the latest at the time of this post.
我不确定 NetBeans 是如何做到这一点的,但自版本 6 以来,JRE 支持启动屏幕。请参阅
I'm not sure how NetBeans does it, but Splash Screens are supported by the JRE since version 6. See http://java.sun.com/developer/technicalArticles/J2SE/Desktop/javase6/splashscreen/
启动屏幕只是 java.awt.Window 或未修饰的 javax.swing.JFrame 的实例。
要创建窗口,只需说
new Window(null)
,然后设置大小和位置(使用takeit你可以计算屏幕中心的位置),然后说window.setVisible(true)
>由于这是您自己的窗口,您可以执行您想要的操作:设置布局、图像、向南添加进程栏等。
您还可以使用 JFrame:new JFrame().setUndecorated(true)`
Splash screen is just a instance of java.awt.Window or undecorated javax.swing.JFrame.
To create window just say
new Window(null)
, then set size and position (using tookit you can calculate where the screen center is) and then saywindow.setVisible(true)
Due to this is your own window you can do what you want: set layout, image, add process bar to the SOUTH etc.
You can also use JFrame: new JFrame().setUndecorated(true)`
有几种方法可以做到这一点。
要制作一个简单的启动屏幕(图像),您可以在 java 应用程序的命令行中指定它。
这是一个简单的示例
但是,如果您想要进度条,你将不得不做一些更复杂的事情,并自己编写一些代码。这是通过以下方式完成的。
这应该显示几乎立即启动,然后在应用程序完全加载后隐藏。
要查看一些启动屏幕代码,请查看此处。链接中的实现仅显示如何使用 -splash 命令实现您可以实现的目标,但它将为您提供一个良好的开始,还包括您请求的进度条。
There are a couple of ways to do this.
To do a simple splash screen (an image) you can specify this in the command line of you java application.
Here is a simple example
However, if you want a progress bar, you are going to have to do something a little more complicated, and write some code yourself. This is done in the following way.
This should show the splash almost immediately, and then hide once the your application is fully loaded.
To see some splash screen code, take a look here. The implementation in the link only shows how to achieve what you can with the -splash command, but it will give you a good start to also include the progress bar that you requested.
我希望这对您有所帮助,这是一个如何使用虚拟进度栏为自己创建简单启动屏幕的小示例:
干杯!
I hope this helps you, it is a small example of how to create yourself a simple splash screen using a dummy Progress Bar:
Cheers!
还可以考虑在 NetBeans 平台(基于 Swing 的 RCP)之上构建应用程序。众多好处之一:它配备了带有进度条的可定制启动屏幕。
进度条示例:

Also consider to build your application on top of the NetBeans Platform (a Swing-based RCP). One of the many benefits: it comes with a customizable splash screen with progress bar.

有一个相当于启动屏幕的 Javafx 示例。然而,这个启动屏幕基本上是一个 java swing 小程序,它从 javafx 调用并显示给用户,并使用进度条和加载内容的标题或多或少地模拟 eclipse 和 netbeans 启动屏幕。 这是链接。
您必须能够获取代码并分离出用 java swings 编写的启动屏幕代码并为自己使用。
这是一个自定义的 java swings 启动屏幕。因此为了使闪屏居中,它使用传统的
There is a sample Javafx equivalent of Splash screen. However this splash screen is basically a java swing applet that is called from javafx to be displayed to the user and simulates more or less eclipse and netbeans splash screen using progress bar and titles for the loaded contents. This is the link.
You must be able to get the code and separate out the splash screen code written in java swings and use it for yourself.
This is a custom java swings splash screen. and hence to center the splash screen it uses the traditional
