显然Java识别出已选择了Dark模式,但是在进行相应的调整方面做得不好。最紧迫的问题是,文本颜色需要从黑色更改为白色,但是还有其他问题。
我使用的是Java 8的最新版本(jdk1.8.0_231.jdk),尚无法移至Java 13,但从release notes发出的声音听起来好像他们仍然对Dark模式有问题。
是否有确定的方法可以解决此不确定的最佳方法。
同样值得注意的是,JDialog子类的其他页面不会变为黑色(除了菜单栏,因此仍然可读,但看起来不正确)

从UIDefaults开始
public static boolean isDarkModeEnabled()
{
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);
boolean result = proc.exitValue() == 0;
MainWindow.logger.severe("Is Dark Mode:" + result);
return result;
}
catch (IOException | InterruptedException | IllegalThreadStateException ex)
{
// IllegalThreadStateException thrown by proc.exitValue(), if process didn't terminate
MainWindow.logger.severe("Unable to determine dark mode");
return false;
}
public static void displayAsDarkMode()
{
Color whitish = new Color(250,250, 250);
Color fadedWhite = new Color(200,200, 200);
Color lightGray = new Color(49,52, 56);
Color darkGray = new Color(30,34,38);
UIManager.put("Label.foreground", whitish);
UIManager.put("Panel.background", lightGray);
UIManager.put("CheckBox.textForeground", whitish);
UIManager.put("CheckBox.foreground", whitish);
UIManager.put("TextField.background", darkGray);
UIManager.put("TextField.foreground", whitish);
UIManager.put("ComboBox.foreground", darkGray);
UIManager.put("ComboBox.textForeground", whitish);
UIManager.put("Button.background", lightGray);
UIManager.put("Button.textForeground", fadedWhite);
UIManager.put("List.background", darkGray);
UIManager.put("List.foreground", whitish);
UIManager.put("TextArea.background", darkGray);
UIManager.put("TextArea.inactiveBackground", darkGray);
UIManager.put("Table.background", darkGray);
UIManager.put("Table.gridColor", lightGray);
}
但是我知道我不是第一个遇到这个问题的人
