	23
	24	Constructor, setting up a wxDisplay instance with the specified display.
	25
	26	\wxheading{Parameters}
	27
	28	\docparam{index}{The index of the display to use. This must be non-negative
	29	and lower than the value returned by \helpref{GetCount()}{wxdisplaygetcount}.}

	32	\membersection{wxDisplay::\destruct{wxDisplay}}\label{wxdisplaydtor}
	33
	34	\func{void}{\destruct{wxDisplay}}{\void}
	35
	36	Destructor.
	37
	38
	39	\membersection{wxDisplay::ChangeMode}\label{wxdisplaychangemode}
	40
	41	\func{bool }{ChangeMode}{\param{const wxVideoMode\& }{mode = wxDefaultVideoMode}}
	42
	43	Changes the video mode of this display to the mode specified
	44	in the mode parameter.
	45
	46	If wxDefaultVideoMode is passed in as the mode parameter,
	47	the defined behaviour is that wxDisplay will reset the video
	48	mode to the default mode used by the display. On Windows,
	49	the behavior is normal. However, there are differences on other
	50	platforms. On Unix variations using X11 extensions it should
	51	behave as defined, but some irregularities may occur.
	52
	53	On wxMac passing in wxDefaultVideoMode as the mode
	54	parameter does nothing. This happens because carbon
	55	no longer has access to DMUseScreenPrefs, an undocumented
	56	function that changed the video mode to the system
	57	default by using the system's 'scrn' resource.
	58
	59
	60	\membersection{wxDisplay::GetCount}\label{wxdisplaygetcount}
	61
	62	\func{static size\_t}{GetCount}{\void}
	63
	64	Returns the number of connected displays.
	65
	66
	67	\membersection{wxDisplay::GetCurrentMode}\label{wxdisplaygetcurrentmode}
	68
	69	\constfunc{wxVideoMode }{GetCurrentMode}{\void}
	70
	71	Returns the current video mode that this display is in.
	72
	73
	74	\membersection{wxDisplay::GetDepth}\label{wxdisplaygetdepth}
	75
	76	\constfunc{int }{GetDepth}{\void}
	77
	78	Returns the bit depth of the display whose index was passed to the constructor.
	79
	80
	81	\membersection{wxDisplay::GetFromPoint}\label{wxdisplaygetfrompoint}
	82
	83	\func{static int}{GetFromPoint}{\param{const wxPoint\& }{pt}}
	84
	85	Returns the index of the display on which the given point lies. Returns -1 if
	86	the point is not on any connected display.
	87
	88	\wxheading{Parameters}
	89
	90	\docparam{pt}{The point to locate.}
	91
	92
	93	\membersection{wxDisplay::GetFromWindow}\label{wxdisplaygetfromwindow}
	94
	95	\func{static int}{GetFromWindow}{\param{wxWindow* }{win}}
	96
	97	Returns the index of the display on which the given window lies.
	98
	99	If the window is on more than one display it gets the display that overlaps the window the most.
	100
	101	Returns -1 if the window is not on any connected display.
	102
	103	Currently wxMSW only.
	104
	105	\wxheading{Parameters}
	106
	107	\docparam{win}{The window to locate.}
	108
	109
	110	\membersection{wxDisplay::GetGeometry}\label{wxdisplaygetgeometry}
	111
	112	\constfunc{wxRect }{GetGeometry}{\void}
	113
	114	Returns the bounding rectangle of the display whose index was passed to the
	115	constructor.
	116
	117
	118	\membersection{wxDisplay::GetModes}\label{wxdisplaygetmodes}
	119
	120	\constfunc{wxArrayVideoModes }{GetModes}{\param{const wxVideoMode\& }{mode = wxDefaultVideoMode}}
	121
	122	Fills and returns an array with all the video modes that
	123	are supported by this display, or video modes that are
	124	supported by this display and match the mode parameter
	125	(if mode is not wxDefaultVideoMode).
	126
	127
	128	\membersection{wxDisplay::GetName}\label{wxdisplaygetname}
	129
	130	\constfunc{wxString }{GetName}{\void}
	131
	132	Returns the display's name. A name is not available on all platforms.
	133
	134
	135	\membersection{wxDisplay::IsPrimary}\label{wxdisplayisprimary}
	136
	137	\func{bool }{IsPrimary}{\void}
	138
	139	Returns true if the display is the primary display. The primary display is the
	140	one whose index is 0.
