/**
* Grabs focus on this window.
*
* All mouse clicks that occur in this window's client area or client-areas
* of any of its unfocusable owned windows are delivered as usual. Whenever
* a click occurs on another app's window (not related via the ownership
* relation with this one, or a focusable owned window), or on non-client
* area of any window (titlebar, etc.), or any third-party app's window, or
* native OS GUI (e.g. a taskbar), the grab is automatically reset, and the
* window that held the grab receives the FOCUS_UNGRAB event.
*
* Note that for this functionality to work correctly, the window must have
* a focus upon calling this method. All owned popup windows that should be
* operable during the grabbed focus state (e.g. nested popup menus) must
* be unfocusable (see {@link #setFocusable}). Clicking a focusable owned
* window will reset the grab due to a focus transfer.
*
* The click that occurs in another window and causes resetting of the grab
* may or may not be delivered to that other window depending on the native
* OS behavior.
*
* If any of the application's windows already holds the grab, it is reset
* prior to grabbing the focus for this window. The method may be called
* multiple times for one window. Subsequent calls do not affect the grab
* status unless it is reset between the calls, in which case the focus
* is grabbed again.
*
* Note that grabbing the focus on an application window may prevent
* delivering certain events to other applications until the grab is reset.
* Therefore, if the application has finished showing popup windows based
* on a user action (e.g. clicking a menu item), and doesn't require the
* grab any more, it should call the {@link #ungrabFocus} method. The
* FOCUS_UNGRAB event signals that the grab has been reset.
*
* A user event handler associated with a menu item must be invoked after
* resetting the grab. Otherwise, if a developer debugs the application and
* has installed a breakpoint in the event handler, the debugger may become
* unoperable due to events blocking for other applications on some
* platforms.
*
* @return {@code true} if the operation is successful
* @throws IllegalStateException if the window isn't focused currently
