[−][src]Enum wayland_protocols::wlr::unstable::screencopy::v1::client::zwlr_screencopy_frame_v1::Event
Variants (Non-exhaustive)
buffer information
Provides information about the frame's buffer. This event is sent once as soon as the frame is created.
The client should then create a buffer with the provided attributes, and send a "copy" request.
frame flags
Provides flags about the frame. This event is sent once before the "ready" event.
Fields of Flags
flags: Flags
indicates frame is available for reading
Called as soon as the frame is copied, indicating it is available for reading. This event includes the time at which presentation happened at.
The timestamp is expressed as tv_sec_hi, tv_sec_lo, tv_nsec triples, each component being an unsigned 32-bit value. Whole seconds are in tv_sec which is a 64-bit value combined from tv_sec_hi and tv_sec_lo, and the additional fractional part in tv_nsec as nanoseconds. Hence, for valid timestamps tv_nsec must be in [0, 999999999]. The seconds part may have an arbitrary offset at start.
After receiving this event, the client should destroy the object.
frame copy failed
This event indicates that the attempted frame copy has failed.
After receiving this event, the client should destroy the object.
carries the coordinates of the damaged region
This event is sent right before the ready event when copy_with_damage is requested. It may be generated multiple times for each copy_with_damage request.
The arguments describe a box around an area that has changed since the last copy request that was derived from the current screencopy manager instance.
The union of all regions received between the call to copy_with_damage and a ready event is the total damage since the prior ready event.
Only available since version 2 of the interface
