\membersection{wxDisplay::wxDisplay}\label{wxdisplayctor}
|
|
|
|
\func{}{wxDisplay}{\param{size\_t }{index = 0}}
|
|
|
|
Constructor, setting up a wxDisplay instance with the specified display.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{index}{The index of the display to use. This must be non-negative
|
|
and lower than the value returned by \helpref{GetCount()}{wxdisplaygetcount}.}
|
|
|
|
|
|
\membersection{wxDisplay::\destruct{wxDisplay}}\label{wxdisplaydtor}
|
|
|
|
\func{void}{\destruct{wxDisplay}}{\void}
|
|
|
|
Destructor.
|
|
|
|
|
|
\membersection{wxDisplay::ChangeMode}\label{wxdisplaychangemode}
|
|
|
|
\func{bool }{ChangeMode}{\param{const wxVideoMode\& }{mode = wxDefaultVideoMode}}
|
|
|
|
Changes the video mode of this display to the mode specified
|
|
in the mode parameter.
|
|
|
|
If wxDefaultVideoMode is passed in as the mode parameter,
|
|
the defined behaviour is that wxDisplay will reset the video
|
|
mode to the default mode used by the display. On Windows,
|
|
the behavior is normal. However, there are differences on other
|
|
platforms. On Unix variations using X11 extensions it should
|
|
behave as defined, but some irregularities may occur.
|
|
|
|
On wxMac passing in wxDefaultVideoMode as the mode
|
|
parameter does nothing. This happens because carbon
|
|
no longer has access to DMUseScreenPrefs, an undocumented
|
|
function that changed the video mode to the system
|
|
default by using the system's 'scrn' resource.
|
|
|
|
|
|
\membersection{wxDisplay::GetCount}\label{wxdisplaygetcount}
|
|
|
|
\func{static size\_t}{GetCount}{\void}
|
|
|
|
Returns the number of connected displays.
|
|
|
|
|
|
\membersection{wxDisplay::GetCurrentMode}\label{wxdisplaygetcurrentmode}
|
|
|
|
\constfunc{wxVideoMode }{GetCurrentMode}{\void}
|
|
|
|
Returns the current video mode that this display is in.
|
|
|
|
|
|
\membersection{wxDisplay::GetDepth}\label{wxdisplaygetdepth}
|
|
|
|
\constfunc{int }{GetDepth}{\void}
|
|
|
|
Returns the bit depth of the display whose index was passed to the constructor.
|
|
|
|
|
|
\membersection{wxDisplay::GetFromPoint}\label{wxdisplaygetfrompoint}
|
|
|
|
\func{static int}{GetFromPoint}{\param{const wxPoint\& }{pt}}
|
|
|
|
Returns the index of the display on which the given point lies. Returns -1 if
|
|
the point is not on any connected display.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{pt}{The point to locate.}
|
|
|
|
|
|
\membersection{wxDisplay::GetGeometry}\label{wxdisplaygetgeometry}
|
|
|
|
\constfunc{wxRect }{GetGeometry}{\void}
|
|
|
|
Returns the bounding rectangle of the display whose index was passed to the
|
|
constructor.
|
|
|
|
|
|
\membersection{wxDisplay::GetModes}\label{wxdisplaygetmodes}
|
|
|
|
\constfunc{wxArrayVideoModes }{GetModes}{\param{const wxVideoMode\& }{mode = wxDefaultVideoMode}}
|
|
|
|
Fills and returns an array with all the video modes that
|
|
are supported by this display, or video modes that are
|
|
supported by this display and match the mode parameter
|
|
(if mode is not wxDefaultVideoMode).
|
|
|
|
|
|
\membersection{wxDisplay::GetName}\label{wxdisplaygetname}
|
|
|
|
\constfunc{wxString }{GetName}{\void}
|
|
|
|
Returns the display's name. A name is not available on all platforms.
|
|
|
|
|
|
\membersection{wxDisplay::IsColour}\label{wxdisplayiscolour}
|
|
|
|
\constfunc{bool }{IsColour}{\void}
|
|
|
|
Returns true if the display is color (has a depth greater than 1).
|
|
|
|
|
|
\membersection{wxDisplay::IsColor}\label{wxdisplayiscolor}
|
|
|
|
\constfunc{bool }{IsColor}{\void}
|
|
|
|
Same as \helpref{IsColour()}{wxdisplayiscolour}.
|
|
|
|
|
|
\membersection{wxDisplay::IsPrimary}\label{wxdisplayisprimary}
|
|
|
|
\func{bool }{IsPrimary}{\void}
|
|
|
|
Returns true if the display is the primary display. The primary display is the
|
|
one whose index is 0.
