为什么在从Netbeans运行的Java应用程序和从Jar运行的Java应用程序中，相同的字体看起来有所不同? [英] Why the same font looks different in Java app run from Netbeans and run from Jar?

问题描述

在我的Java Swing应用程序中，我有一些JTextAreas，我意识到从Netbeans运行时和从Jar文件运行时，文本看起来都不同，为什么?如何使它们看起来相同?

In my Java Swing app I have some JTextAreas, I realize the text looks different when it's run from Netbeans and when the app is run from a Jar file, why ? How to make them look the same ?

JTextArea Client_Side_TextArea=new JTextArea(),Network_TextArea=new JTextArea();

setLayout(new BorderLayout());

Client_Side_TextArea.setFont(new Font("Monospaced",0,15));
Client_Side_TextArea.setForeground(new Color(0,28,218));
Client_Side_TextArea.setPreferredSize(new Dimension(290,300));
Client_Side_TextArea.append("           Client Side\n================================\n");
add("West",Client_Side_TextArea);

Network_TextArea.setFont(new Font("Monospaced",0,15));
Network_TextArea.setBackground(new Color(226,226,226));
Network_TextArea.setForeground(new Color(0,28,218));
Network_TextArea.setPreferredSize(new Dimension(270,300));
Network_TextArea.append("            Network Connection\n =========================================\n");
add("Center",Network_TextArea);

在下图中，上半部分是使用Netbeans运行的应用程序，下半部分是从Jar文件运行时的外观:

In the following image, the upper part is from the app run with Netbeans, the lower part is how it looks when run from a Jar file :

推荐答案

这是预期的行为:如外观& feel 可能会进一步针对特定目的改进字体的选择.除非平台，版本和设置相同，否则字体可能会有所不同.可以在此处找到完整的示例以及有关映射的更多信息.

This is the expected behavior: as discussed in the Font API, each supported platform may map a different physical font to a particulate logical font such as Font.MONOSPACED. Each look & feel may further refine the choice of font for a particular purpose. Unless the platforms, versions and settings are identical, the fonts may vary. A complete example and more on the mapping may be found here.

此外，出于此处所引用的原因，请勿使用setPreferredSize().如果您选择覆盖getPreferredSize()，请确保不属于此陷阱.

In addition, for the reasons cited here, don't use setPreferredSize(). If you choose to override getPreferredSize(), be certain not to fall into this trap.
