Class
CoglOutput
Description [src]
final class Cogl.Output : GObject.Object
{
/* No available fields */
}Information about an output device
The CoglOutput object holds information about an output device
such as a monitor or laptop display. It can be queried to find
out the position of the output with respect to the screen
coordinate system and other information such as the resolution
and refresh rate of the device.
There can be any number of outputs which may overlap: the same area of the screen may be displayed by multiple output devices.
XXX: though it’s possible to query the position of the output
with respect to screen coordinates, there is currently no way
of finding out the position of a CoglOnscreen in screen
coordinates, at least without using windowing-system specific
API’s, so it’s not easy to get the output positions relative
to the CoglOnscreen.
Instance methods
cogl_output_get_mm_height
Gets the physical height of the output. In some cases (such as as a projector), the value returned here might correspond to nominal resolution rather than the actual physical size of the output device.
cogl_output_get_mm_width
Gets the physical width of the output. In some cases (such as as a projector), the value returned here might correspond to nominal resolution rather than the actual physical size of the output device.
cogl_output_get_refresh_rate
Gets the number of times per second that the output device refreshes the display contents.
cogl_output_get_subpixel_order
For an output device where each pixel is made up of smaller components with different colors, returns the layout of the subpixel components.
cogl_output_get_x
Gets the X position of the output with respect to the coordinate system of the screen.
cogl_output_get_y
Gets the Y position of the output with respect to the coordinate system of the screen.
Signals
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
