Class

WPEPlatformScreen

Description [src]

abstract class WPEPlatform.Screen : GObject.Object
{
  WPEScreenPrivate* priv
}

A monitor connected to a WPEDisplay.

WPEScreen is an abstract class that platform implementations derive to represent a monitor. Enumerate the screens of a display with wpe_display_get_n_screens() and wpe_display_get_screen().

A screen exposes its position, size, physical size, scale and refresh rate, and provides a WPEScreenSyncObserver to be notified on vertical sync.

Instance methods

wpe_screen_get_height

Get the height of screen in logical coordinates.

wpe_screen_get_id

Get the screen identifier. The identifier is a non-zero value to uniquely identify a WPEScreen.

wpe_screen_get_physical_height

Get the physical height of screen in millimeters.

wpe_screen_get_physical_width

Get the physical width of screen in millimeters.

wpe_screen_get_refresh_rate

Get the refresh rate of screen in milli-Hertz.

wpe_screen_get_scale

Get the screen scale factor.

wpe_screen_get_sync_observer

Get the WPEScreenSyncObserver of screen. If screen sync is not supported, NULL is returned.

wpe_screen_get_width

Get the width of screen in logical coordinates.

wpe_screen_get_x

Get the x coordinate of the screen position in logical coordinates.

wpe_screen_get_y

Get the y coordinate of the screen position in logical coordinates.

wpe_screen_invalidate

Invalidate screen. This will release all the platform resources associated with screen. The properties cached will not be modified so they are still available after invalidation.

wpe_screen_set_physical_size

Set the physical size of screen in millimeters.

wpe_screen_set_position

Set the position of screen in logical coordinates.

wpe_screen_set_refresh_rate

Set the refresh rate of screen in milli-Hertz.

wpe_screen_set_scale
