20\membersection{wxDisplay::wxDisplay}\label{wxdisplayctor}
21
22\func{}{wxDisplay}{\param{size\_t }{index = 0}}
23
24Constructor, 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
29and lower than the value returned by \helpref{GetCount()}{wxdisplaygetcount}.}

32\membersection{wxDisplay::\destruct{wxDisplay}}\label{wxdisplaydtor}
33
34\func{void}{\destruct{wxDisplay}}{\void}
35
36Destructor.

38
39\membersection{wxDisplay::ChangeMode}\label{wxdisplaychangemode}
40
41\func{bool }{ChangeMode}{\param{const wxVideoMode\& }{mode = wxDefaultVideoMode}}
42
43Changes the video mode of this display to the mode specified
44in the mode parameter.
45
46If wxDefaultVideoMode is passed in as the mode parameter,
47the defined behaviour is that wxDisplay will reset the video
48mode to the default mode used by the display. On Windows,
49the behavior is normal. However, there are differences on other
50platforms. On Unix variations using X11 extensions it should
51behave as defined, but some irregularities may occur.
52
53On wxMac passing in wxDefaultVideoMode as the mode
54parameter does nothing. This happens because carbon
55no longer has access to DMUseScreenPrefs, an undocumented
56function that changed the video mode to the system
57default by using the system's 'scrn' resource.

60\membersection{wxDisplay::GetClientArea}\label{wxdisplaygetclientarea}
61
62\constfunc{wxRect }{GetClientArea}{\void}
63
64Returns the client area of the display. The client area is the part of the
65display available for the normal (non full screen) windows, usually it is the
66same as \helpref{GetGeometry}{wxdisplaygetgeometry} but it could be less if
67there is a taskbar (or equivalent) on this display.

74\membersection{wxDisplay::GetCount}\label{wxdisplaygetcount}
75
76\func{static size\_t}{GetCount}{\void}
77
78Returns the number of connected displays.

80
81\membersection{wxDisplay::GetCurrentMode}\label{wxdisplaygetcurrentmode}
82
83\constfunc{wxVideoMode }{GetCurrentMode}{\void}
84
85Returns the current video mode that this display is in.
86
87
88\membersection{wxDisplay::GetDepth}\label{wxdisplaygetdepth}
89
90\constfunc{int }{GetDepth}{\void}
91
92Returns the bit depth of the display whose index was passed to the constructor.
93
94
95\membersection{wxDisplay::GetFromPoint}\label{wxdisplaygetfrompoint}
96
97\func{static int}{GetFromPoint}{\param{const wxPoint\& }{pt}}
98
99Returns the index of the display on which the given point lies. Returns
100\texttt{wxNOT\_FOUND} if the point is not on any connected display.
101
102\wxheading{Parameters}
103
104\docparam{pt}{The point to locate.}
105
106
107\membersection{wxDisplay::GetFromWindow}\label{wxdisplaygetfromwindow}
108
109\func{static int}{GetFromWindow}{\param{wxWindow* }{win}}
110
111Returns the index of the display on which the given window lies.
112
113If the window is on more than one display it gets the display that overlaps the window the most.
114
115Returns \texttt{wxNOT\_FOUND} if the window is not on any connected display.
116
117\wxheading{Parameters}
118
119\docparam{win}{The window to locate.}
120
121
122\membersection{wxDisplay::GetGeometry}\label{wxdisplaygetgeometry}
123
124\constfunc{wxRect }{GetGeometry}{\void}
125
126Returns the bounding rectangle of the display whose index was passed to the
127constructor.

134\membersection{wxDisplay::GetModes}\label{wxdisplaygetmodes}
135
136\constfunc{wxArrayVideoModes }{GetModes}{\param{const wxVideoMode\& }{mode = wxDefaultVideoMode}}
137
138Fills and returns an array with all the video modes that
139are supported by this display, or video modes that are
140supported by this display and match the mode parameter
141(if mode is not wxDefaultVideoMode).
142
143
144\membersection{wxDisplay::GetName}\label{wxdisplaygetname}
145
146\constfunc{wxString }{GetName}{\void}
147
148Returns the display's name. A name is not available on all platforms.
149
150
151\membersection{wxDisplay::IsPrimary}\label{wxdisplayisprimary}
152
153\func{bool }{IsPrimary}{\void}
154
155Returns true if the display is the primary display. The primary display is the
156one whose index is 0.
