Weiss einer , wie man ne JCheckBox transparent machen kann?
public void setOpaque(boolean isOpaque)
If true the component paints every pixel within its bounds. Otherwise, the component may not paint some or all of its pixels, allowing the underlying pixels to show through.
The default value of this property is false for JComponent. However, the default value for this property on most standard JComponent subclasses (such as JButton and JTree) is look-and-feel dependent.
Parameters:
isOpaque - true if this component should be opaque
