我在 Java Swing应用程序中使用Substance外观版本6.0.该应用程序适用于我,但一些应用程序用户,特别是那些使用Windows 7的用户正在获得物质异常：

java.lang.InternalError: Unable to instantiate org.pushingpixels.substance.internal.contrib.randelshofer.quaqua.colorchooser.ColorPalettesChooser

此异常发生在此代码的最后一行：

JXColorSelectionButton myColorSelectionButton = new JXColorSelectionButton();

myColorSelectionButton.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
myColorSelectionButton.setFocusPainted(false);
contentPane.add(myColorSelectionButton,cc.xy(29,19));
/**
  * Some code here
  */
myColorSelectionButton.setBackground( Color.WHITE );  // Excepton occurres here !!

我找不到一个问这个物质问题的地方,所以如果你可以帮助我,我将不胜感激.

解决方法

当前构建的非实质性(这是物质的维护分支)和SwingX不会出现此错误,因此它是一个已修复的错误.

这是一个代码示例

import java.awt.Color
import javax.swing.*
import org.jdesktop.swingx.JXColorSelectionButton

SwingUtilities.invokeAndWait {
@Grapes( 
[@Grab(group='org.swinglabs',module='swingx-core',version='1.6.2-2'),@Grab(group='com.github.insubstantial',module='substance-swingx',version='7.0') ]
)
    JFrame frame = new JFrame("Test");
    JXColorSelectionButton myColorSelectionButton = new JXColorSelectionButton();

    myColorSelectionButton.setFocusPainted(false);
    frame.add(myColorSelectionButton);
    myColorSelectionButton.setBackground( Color.WHITE );  // Excepton occurres here !!
    frame.pack()
    frame.setVisible(true)
}
