static int32 xtd::forms::native::screen::pixels_per_inch ( size_t index )

staticprotected

Gets the pixels per inch of the display.

Parameters

index The screen index.

Returns: The pixels per inch of the display.

Warning: Internal use only

static bool xtd::forms::native::screen::primary ( size_t index )

staticprotected

Gets a value indicating whether a particular display is the primary device.

Parameters

index The screen index.

Returns: true if index display is primary; otherwise, false.

Warning: Internal use only

◆ scale_factor()

static double xtd::forms::native::screen::scale_factor ( size_t index )

staticprotected

Gets the scale factor of the display.

Parameters

index The screen index.

Returns: The scale factor of the display.

Warning: Internal use only

◆ standard_pixels_per_inch()

static int32 xtd::forms::native::screen::standard_pixels_per_inch ( )

staticprotected

Gets the standard pixels per inch.

Returns: The standard pixels per inch.

Remarks: The standard value is 72 for macOS; 96 for Windows and linux.

Warning: Internal use only

◆ from_handle()

static size_t xtd::forms::native::screen::from_handle ( intptr handle )

staticprotected

Retrieves a screen for the display that contains the largest portion of the object referred to by the specified handle.

Parameters

handle The window handle for which to retrieve the screen.

Returns: A screen index for the display that contains the largest region of the object. In multiple display environments where no display contains any portion of the specified handle, the display closest to the object is returned.

Warning: Internal use only

◆ from_point()

static size_t xtd::forms::native::screen::from_point ( const drawing::point & point )

staticprotected

Retrieves a screen for the display that contains the specified point.

Parameters

point A xtd::drawing::point that specifies the location for which to retrieve a screen.

Returns: A screen index for the display that contains the point. In multiple display environments where no display contains the point, the display closest to the specified point is returned.
