Examples with FlavorListener java.awt.datatransfer.FlavorListener used on opensource projects

Example 1 with FlavorListener

use of java.awt.datatransfer.FlavorListener in project jdk8u_jdk by JetBrains.

the class SunClipboard method checkChange.

     * Checks change of the <code>DataFlavor</code>s and, if necessary,
     * posts notifications on <code>FlavorEvent</code>s to the
     * AppContexts' EDTs.
     * The parameter <code>formats</code> is null iff we have just
     * failed to get formats available on the clipboard.
     *
     * @param formats data formats that have just been retrieved from
     *        this clipboard
