Fetches the current color used to render the selection.

Usage

From source file:Main.java

/**
 * Determines whether the SelectedTextColor should be used for painting text
 * foreground for the specified highlight.
 *
 * Returns true only if the highlight painter for the specified highlight
 * is the swing painter (whether inner class of javax.swing.text.DefaultHighlighter
 * or com.sun.java.swing.plaf.windows.WindowsTextUI) and its background color
 * is null or equals to the selection color of the text component.
 *
 * This is a hack for fixing both bugs 4761990 and 5003294
