当我使用SeaGlass LAF所有的东西都没问题,但是当我请求一个有来自RSyntaxTextArea的对象的页面包给我一个错误时,我对nimbus没有问题,所有的东西都完美无缺...... 注意:我在主类中使用此方法来更改程序的所有窗口的整个LAF:
try {
UIManager.setLookAndFeel("com.seaglasslookandfeel.SeaGlassLookAndFeel");
} catch (Exception e) {
System.out.println("UIManager Exception : " + e);
}
整个程序使SeaGlass LAF生效,我可以手动设置每个窗口的LAF并从RSyntaxTextArea包中隔离出具有对象的窗口吗?
