25 | ||
26 | \func{}{wxDisplay}{\param{unsigned }{index = 0}} | |
27 | ||
28 | Constructor, setting up a wxDisplay instance with the specified display. | |
29 | ||
30 | \wxheading{Parameters} | |
31 | ||
32 | \docparam{index}{The index of the display to use. This must be non-negative | |
33 | and lower than the value returned by \helpref{GetCount()}{wxdisplaygetcount}.} | |
34 | ||
35 | ||
36 | \membersection{wxDisplay::\destruct{wxDisplay}}\label{wxdisplaydtor} | |
37 | ||
38 | \func{void}{\destruct{wxDisplay}}{\void} | |
39 | ||
40 | Destructor. | |
41 | ||
42 | ||
43 | \membersection{wxDisplay::ChangeMode}\label{wxdisplaychangemode} | |
44 | ||
45 | \func{bool }{ChangeMode}{\param{const wxVideoMode\& }{mode = wxDefaultVideoMode}} | |
46 | ||
47 | Changes the video mode of this display to the mode specified | |
48 | in the mode parameter. | |
49 | ||
50 | If wxDefaultVideoMode is passed in as the mode parameter, | |
51 | the defined behaviour is that wxDisplay will reset the video | |
52 | mode to the default mode used by the display. On Windows, | |
53 | the behavior is normal. However, there are differences on other | |
54 | platforms. On Unix variations using X11 extensions it should | |
55 | behave as defined, but some irregularities may occur. | |
56 | ||
57 | On wxMac passing in wxDefaultVideoMode as the mode | |
58 | parameter does nothing. This happens because carbon | |
59 | no longer has access to DMUseScreenPrefs, an undocumented | |
60 | function that changed the video mode to the system | |
61 | default by using the system's 'scrn' resource. | |
62 | ||
63 | ||
64 | \membersection{wxDisplay::GetClientArea}\label{wxdisplaygetclientarea} | |
65 | ||
66 | \constfunc{wxRect }{GetClientArea}{\void} | |
67 | ||
68 | Returns the client area of the display. The client area is the part of the | |
69 | display available for the normal (non full screen) windows, usually it is the | |
70 | same as \helpref{GetGeometry}{wxdisplaygetgeometry} but it could be less if | |
71 | there is a taskbar (or equivalent) on this display. | |

77 | ||
78 | \membersection{wxDisplay::GetCount}\label{wxdisplaygetcount} | |
79 | ||
80 | \func{static unsigned }{GetCount}{\void} | |
81 | ||
82 | Returns the number of connected displays. | |
83 | ||
84 | ||
85 | \membersection{wxDisplay::GetCurrentMode}\label{wxdisplaygetcurrentmode} | |
86 | ||
87 | \constfunc{wxVideoMode }{GetCurrentMode}{\void} | |
88 | ||
89 | Returns the current video mode that this display is in. | |
90 | ||
91 | ||
92 | \membersection{wxDisplay::GetDepth}\label{wxdisplaygetdepth} | |
93 | ||
94 | \constfunc{int }{GetDepth}{\void} | |
95 | ||
96 | Returns the bit depth of the display whose index was passed to the constructor. | |
97 | ||
98 | ||
99 | \membersection{wxDisplay::GetFromPoint}\label{wxdisplaygetfrompoint} | |
100 | ||
101 | \func{static int}{GetFromPoint}{\param{const wxPoint\& }{pt}} | |
102 | ||
103 | Returns the index of the display on which the given point lies. Returns | |
104 | \texttt{wxNOT\_FOUND} if the point is not on any connected display. | |
105 | ||
106 | \wxheading{Parameters} | |
107 | ||
108 | \docparam{pt}{The point to locate.} | |
109 | ||
110 | ||
111 | \membersection{wxDisplay::GetFromWindow}\label{wxdisplaygetfromwindow} | |
112 | ||
113 | \func{static int}{GetFromWindow}{\param{const wxWindow* }{win}} | |
114 | ||
115 | Returns the index of the display on which the given window lies. | |
116 | ||
117 | If the window is on more than one display it gets the display that overlaps the window the most. | |
118 | ||
119 | Returns \texttt{wxNOT\_FOUND} if the window is not on any connected display. | |
120 | ||
121 | \wxheading{Parameters} | |
122 | ||
123 | \docparam{win}{The window to locate.} | |
124 | ||
125 | ||
126 | \membersection{wxDisplay::GetGeometry}\label{wxdisplaygetgeometry} | |
127 | ||
128 | \constfunc{wxRect }{GetGeometry}{\void} | |
129 | ||
130 | Returns the bounding rectangle of the display whose index was passed to the | |
131 | constructor. | |
132 | ||

138 | \membersection{wxDisplay::GetModes}\label{wxdisplaygetmodes} | |
139 | ||
140 | \constfunc{wxArrayVideoModes }{GetModes}{\param{const wxVideoMode\& }{mode = wxDefaultVideoMode}} | |
141 | ||
142 | Fills and returns an array with all the video modes that | |
143 | are supported by this display, or video modes that are | |
144 | supported by this display and match the mode parameter | |
145 | (if mode is not wxDefaultVideoMode). | |
146 | ||
147 | ||
148 | \membersection{wxDisplay::GetName}\label{wxdisplaygetname} | |
149 | ||
150 | \constfunc{wxString }{GetName}{\void} | |
151 | ||
152 | Returns the display's name. A name is not available on all platforms. | |
153 | ||
154 | ||
155 | \membersection{wxDisplay::IsPrimary}\label{wxdisplayisprimary} | |
156 | ||
157 | \func{bool }{IsPrimary}{\void} | |
158 | ||
159 | Returns true if the display is the primary display. The primary display is the | |
160 | one whose index is 0. | |
