Detailed Description

This class typically, but not always, corresponds to a physical display connected to the system.

A fake Display may exist on a headless system, or a Display may correspond to a remote, virtual display. All size and position values are in density independent pixel (DIP) coordinates unless otherwise indicated. Methods must be called on the browser process UI thread unless otherwise indicated.

Member Function Documentation

◆ ConvertPointFromPixels()

virtual void CefDisplay::ConvertPointFromPixels ( CefPoint & point )

pure virtual

Convert |point| from pixel coordinates to DIP coordinates using this Display's device scale factor.

◆ ConvertPointToPixels()

virtual void CefDisplay::ConvertPointToPixels ( CefPoint & point )

pure virtual

Convert |point| from DIP coordinates to pixel coordinates using this Display's device scale factor.

◆ ConvertScreenPointFromPixels()

static CefPoint CefDisplay::ConvertScreenPointFromPixels ( const CefPoint & point )

static

Convert |point| from pixel screen coordinates to DIP screen coordinates.

This method is only used on Windows.

◆ ConvertScreenPointToPixels()

static CefPoint CefDisplay::ConvertScreenPointToPixels ( const CefPoint & point )

static

Convert |point| from DIP screen coordinates to pixel screen coordinates.

This method is only used on Windows.

◆ ConvertScreenRectFromPixels()

static CefRect CefDisplay::ConvertScreenRectFromPixels ( const CefRect & rect )

static

Convert |rect| from pixel screen coordinates to DIP screen coordinates.

This method is only used on Windows.

◆ ConvertScreenRectToPixels()

static CefRect CefDisplay::ConvertScreenRectToPixels ( const CefRect & rect )

static

Convert |rect| from DIP screen coordinates to pixel screen coordinates.

This method is only used on Windows.

◆ GetAllDisplays()

static void CefDisplay::GetAllDisplays ( std::vector< CefRefPtr< CefDisplay >> & displays )

static

Returns all Displays.

Mirrored displays are excluded; this method is intended to return distinct, usable displays.

◆ GetBounds()

virtual CefRect CefDisplay::GetBounds ( )

pure virtual

Returns this Display's bounds in DIP screen coordinates.

This is the full size of the display.

◆ GetDeviceScaleFactor()

virtual float CefDisplay::GetDeviceScaleFactor ( )

pure virtual

Returns this Display's device pixel scale factor.

This specifies how much the UI should be scaled when the actual output has more pixels than standard displays (which is around 100~120dpi). The potential return values differ by platform.

◆ GetDisplayCount()

static size_t CefDisplay::GetDisplayCount ( )

static

Returns the total number of Displays.

Mirrored displays are excluded; this method is intended to return the number of distinct, usable displays.

◆ GetDisplayMatchingBounds()

static CefRefPtr<CefDisplay> CefDisplay::GetDisplayMatchingBounds	(	const CefRect &	bounds,
		bool	input_pixel_coords
	)

static

Returns the Display that most closely intersects |bounds|.

Set |input_pixel_coords| to true if |bounds| is in pixel screen coordinates instead of DIP screen coordinates.

◆ GetDisplayNearestPoint()

static CefRefPtr<CefDisplay> CefDisplay::GetDisplayNearestPoint	(	const CefPoint &	point,
		bool	input_pixel_coords
	)

static

Returns the Display nearest |point|.

Set |input_pixel_coords| to true if |point| is in pixel screen coordinates instead of DIP screen coordinates.

◆ GetID()

virtual int64_t CefDisplay::GetID ( )

pure virtual

Returns the unique identifier for this Display.

◆ GetPrimaryDisplay()

static CefRefPtr<CefDisplay> CefDisplay::GetPrimaryDisplay ( )

static

Returns the primary Display.

◆ GetRotation()

virtual int CefDisplay::GetRotation ( )

pure virtual

Returns this Display's rotation in degrees.

◆ GetWorkArea()

virtual CefRect CefDisplay::GetWorkArea ( )

pure virtual

Returns this Display's work area in DIP screen coordinates.

This excludes areas of the display that are occupied with window manager toolbars, etc.
