我无法找到有关如何在OS X(OS X 10.10 Yosemite中引入)中为暗模式设置菜单栏图标的任何信息。我已经看过这篇文章http://mail.openjdk.java.net/pipermail/macosx-port-dev/2014-October/006740.html,但没有任何答案。我知道这里已经为Objective-C讨论了How to detect dark mode in Yosemite to change the status bar menu icon,但不确定这是否可以用Java来完成。
有没有办法实现这个目标?

我遇到了同样的问题,通过调用defaults read
命令并分析退出代码来解决它:
/**
* @return true if <code>defaults read -g AppleInterfaceStyle</code> has an exit status of <code>0</code> (i.e. _not_ returning "key not found").
*/
private boolean isMacMenuBarDarkMode() {
try {
// check for exit status only. Once there are more modes than "dark" and "default", we might need to analyze string contents..
final Process proc = Runtime.getRuntime().exec(new String[] {"defaults", "read", "-g", "AppleInterfaceStyle"});
proc.waitFor(100, TimeUnit.MILLISECONDS);
return proc.exitValue() == 0;
} catch (IOException | InterruptedException | IllegalThreadStateException ex) {
// IllegalThreadStateException thrown by proc.exitValue(), if process didn't terminate
LOG.warn("Could not determine, whether 'dark mode' is being used. Falling back to default (light) mode.");
return false;
}
}
现在您可以加载不同的图片并在java.awt.TrayIcon中使用它们:
// java.awt.* controls are well suited for displaying menu bar icons on OS X
final Image image;
if (isMacMenuBarDarkMode()) {
image = Toolkit.getDefaultToolkit().getImage(getClass().getResource("/tray_icon_darkmode.png"));
} else {
image = Toolkit.getDefaultToolkit().getImage(getClass().getResource("/tray_icon_default.png"));
}
