grabFocus

public boolean grabFocus()

Description copied from interface: com.sun.javafx.embed.HostInterface

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 #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 HostInterface.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.

Returns:

true if the operation is successful

ungrabFocus

public void ungrabFocus()

Description copied from interface: com.sun.javafx.embed.HostInterface

Manually ungrabs focus grabbed on this window previously. This method resets the grab, and forces sending of the FOCUS_UNGRAB event. It should be used when popup windows (such as menus) should be dismissed manually, e.g. when a user clicks a menu item which usually causes the menus to hide.
