                            | flags | 
                            
                                 Flag(s) to define the panel behavior. Multiple flags can be set
                                    by using the pipe "|". Following flags are available: 
                                
                                    - 
                                        
"FramelessWindowHint" - produces a borderless
                                            window. The user cannot move or resize a borderless
                                            window via the window system. On X11, the result of the
                                            flag is dependent on the window manager and its ability
                                            to understand Motif and/or NETWM hints. Most existing
                                            modern window managers can handle this. 
                                     
                                    - 
                                        
"NoDropShadowWindowHint" - Disables window drop
                                            shadow on supporting platforms. 
                                     
                                    - 
                                        
"CustomizeWindowHint" - is used to enable
                                            customization of the window controls. This flag must be
                                            set to allow the WindowTitleHint, WindowSystemMenuHint,
                                            WindowMinimizeButtonHint, WindowMaximizeButtonHint and
                                            WindowCloseButtonHint flags to be changed. 
                                     
                                    - 
                                        
"WindowTitleHint" - enables the title bar for the
                                            window. 
                                     
                                    - 
                                        
"WindowSystemMenuHint" - adds a window system menu
                                            and possible a close button (e.g. on Mac). If you need
                                            to hide or show a close button, it is more portable to
                                            use WindowCloseButtonHint. 
                                     
                                    - 
                                        
"WindowMinimizeButtonHint" - adds a minimize
                                            button. On some platforms this implies
                                            WindowSystemMenuHint for it to work. 
                                     
                                    - 
                                        
"WindowMaximizeButtonHint" - adds a maximize
                                            button. On some platforms this implies
                                            WindowSystemMenuHint for it to work. 
                                     
                                    - 
                                        
"WindowCloseButtonHint" - adds a close button. On
                                            some platforms this implies WindowSystemMenuHint for it
                                            to work. 
                                     
                                    - 
                                        
"WindowShadeButtonHint" - adds a shade button in
                                            place of the minimize button if the underlying window
                                            manager supports it. 
                                     
                                    - 
                                        
"WindowStaysOnTopHint" - informs the window
                                            systems that the window should stay on top of all other
                                            windows. 
                                     
                                    - 
                                        
"WindowStaysOnBottomHint" - informs the window
                                            system that the window should stay on bottom of all
                                            other windows. 
                                     
                                    - 
                                        
"WindowTransparentForInput" - informs the window
                                            system that this window is used only for output
                                            (displaying something) and does not take input.
                                            Therefore input events should pass through as if it
                                            wasn't there. 
                                     
                                    - 
                                        
"WindowDoesNotAcceptFocus" - informs the window
                                            system that this window should not receive the input
                                            focus.
