为什么用JColorChooser后界面都看不到了?
Failed to create live visual subcomponent contentPane as JPanel contentPane;. Creating using default constructor javax.swing.JPanelFailed to create live visual subcomponent ccc as JColorChooser ccc = new JColorChooser();. Creating a red component in its place.
这个是什么意思???

我以前也遇到类似的问题,后来发现是因为使用了char型的变量删去使用char的变量(换成int型试试),我的问题解决了问题是有些诡异,我也不太明白
