Example 4 with InvocationEvent

use of java.awt.event.InvocationEvent in project jdk8u_jdk by JetBrains.

the class XDecoratedPeer method handleWindowFocusIn.

public void handleWindowFocusIn(long serial) {
    if (null == actualFocusedWindow) {
        super.handleWindowFocusIn(serial);
    } else {
        /*
             * Fix for 6314575.
             * If this is a result of clicking on one of the Frame's component
             * then 'actualFocusedWindow' shouldn't be focused. A decision of focusing
             * it or not should be made after the appropriate Java mouse event (if any)
             * is handled by the component where 'actualFocusedWindow' value may be reset.
             *
             * The fix is based on the empiric fact consisting in that the component
             * receives native mouse event nearly at the same time the Frame receives
             * WM_TAKE_FOCUS (when FocusIn is generated via XSetInputFocus call) but
             * definetely before the Frame gets FocusIn event (when this method is called).
             */
