Class API¶
wx.Display(object)¶Possible constructors:
Display()
Display(index)
Display(window)
Determines the sizes and locations of displays connected to the system.
__init__(self, *args, **kw)¶
Overloaded Implementations:
__init__ (self)
Default constructor creating wx.Display object representing the primary display.
__init__ (self, index)
Constructor, setting up a wx.Display instance with the specified display.
index (int) – The index of the display to use. This must be non-negative and lower than the value returned by GetCount .
__init__ (self, window)
Constructor creating the display object associated with the given window.
This is the most convenient way of finding the display on which the given window is shown while falling back to the default display if it is not shown at all or positioned outside of any display.
window (wx.Window) – A valid, i.e. non-null, window.
New in version 4.1/wxWidgets-3.1.2.
ChangeMode(self, mode=DefaultVideoMode)¶Changes the video mode of this display to the mode specified in the mode parameter.
If DefaultVideoMode is passed in as the mode parameter, the defined behaviour is that wx.Display will reset the video mode to the default mode used by the display. On Windows, the behaviour 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.
mode (wx.VideoMode) –
bool
GetClientArea(self)¶Returns the client area of the display.
The client area is the part of the display available for the normal (non full screen) windows, usually it is the same as GetGeometry but it could be less if there is a taskbar (or equivalent) on this display.
GetCount()¶Returns the number of connected displays.
int
GetCurrentMode(self)¶Returns the current video mode that this display is in.
GetDepth(self)¶Returns display depth, i.e.
number of bits per pixel (0 if unknown)
int
New in version 4.1/wxWidgets-3.1.2.
GetFromPoint(pt)¶Returns the index of the display on which the given point lies, or NOT_FOUND if the point is not on any connected display.
pt (wx.Point) – The point to locate.
int
GetFromWindow(win)¶Returns the index of the display on which the given window lies.
If the window is on more than one display it gets the display that overlaps the window the most.
Returns NOT_FOUND if the window is not on any connected display.
win (wx.Window) – The window to locate.
int
GetGeometry(self)¶Returns the bounding rectangle of the display whose index was passed to the constructor.
See also
GetModes(self, mode=DefaultVideoMode)¶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 DefaultVideoMode).
mode (wx.VideoMode) –
ArrayVideoModes
GetName(self)¶Returns the display’s name.
The returned value is currently an empty string under all platforms except MSW.
string
GetPPI(self)¶Returns display resolution in pixels per inch.
Horizontal and vertical resolution are returned in x and y components of the wx.Size object respectively.
If the resolution information is not available, returns:
wx.Size(0, 0)
New in version 4.1/wxWidgets-3.1.2.
GetScaleFactor(self)¶Returns scaling factor used by this display.
The scaling factor is the ratio between GetPPI and GetStdPPI (it is implicitly assumed that this ratio is the same for both horizontal and vertical components).
float
New in version 4.1/wxWidgets-3.1.5.
GetStdPPI()¶Returns default display resolution for the current platform as wx.Size.
This function is equivalent to constructing wx.Size object with both components set to GetStdPPIValue .
New in version 4.1/wxWidgets-3.1.5.
GetStdPPIValue()¶Returns default display resolution for the current platform in pixels per inch.
This function mostly used internally, use GetPPI to get the actual display resolution.
Currently the standard PPI is the same in both horizontal and vertical directions on all platforms and its value is 96 everywhere except under Apple devices (those running macOS, iOS, watchOS etc), where it is 72.
int
New in version 4.1/wxWidgets-3.1.5.

IsPrimary(self)¶Returns True if the display is the primary display.
The primary display is the one whose index is 0.
bool

CurrentMode¶See GetCurrentMode
Geometry¶See GetGeometry
