        use the more targeted installJComponentRepainterOnWindowFocusChanged(JComponent) method.
        Creates and installs a WindowFocusListener on the given Window which calls the Window's repaint() method on focus state changes.
        Parameters:
        window - the Window to repaint on focus state changes.
        Returns:
        the listener installed.

      • isParentWindowFocused

        true if the given Component's has a parent Window (i.e. it's not null) and that Window is currently active (focused).
        Parameters:
        component - the Component to check the parent Window's focus for.
        Returns:
        true if the given Component's parent Window is currently active.

        public static void installWeakWindowFocusListener​(javax.swing.JComponent component,
                                                  java.awt.event.WindowFocusListener focusListener)
        Installs a WindowFocusListener on the given JComponent's parent Window. If the JComponent doesn't yet have a parent, then the listener will be installed when the component is added to a container.
        Parameters:
        component - the component who's parent frame to listen to focus changes on.
        focusListener - the WindowFocusListener to notify when focus changes.

        public static void installJComponentRepainterOnWindowFocusChanged​(javax.swing.JComponent component)
        Installs a listener on the given JComponent's parent Window that repaints the given component when the parent window's focused state changes. If the given component does not have a parent at the time this method is called, then an ancestor listener will be installed that installs a window listener when the components parent changes.
        Parameters:
        component - the JComponent to add the repaint focus listener to.
