Question

我在Java Swing应用程序中使用了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例外：

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，所以如果你能帮助我，我将不胜感激。

Answer 1

物质不再更新，在Java 7上已被破坏。

然而，有人通过分叉并称之为未经证实来挑选项目：http://shemnon.com/speling/

它支持Java 7，似乎对下一次更新有很大的计划。

它应该像交换库一样简单，以使其在您的项目中工作。

Answer 2

非实质性的当前构建（物质的维护分支）和SwingX不会出现此错误，因此这是一个已修复的错误。

这是

中的代码示例

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)
}
