Xtst::RecordExtension

Connects to the display and raises if Record Extension Library was not found on the system.

Returns a new context. A range can be created with create_range.

Example usage:

range = record.create_range
range.device_events.first = X11::KeyPress
range.device_events.last = X11::ButtonRelease
context = record.create_context(record_range)

Create a mutable range for usage in create_context.

The underlying Display object. Docs recommend using two separate connections for control and data.

Start listening for the events configured in context.range. This method does not block. The block does not get run on its own, you need to additionally repeatedly call process_replies. For the structure of record_data.data, please refer to xEvent (NOT XEvent) at _xEvent in Xproto.h. There are no docs available for this, only other reference implementations.

Example usage:

record.enable_context_async(context) do |record_data|
  next if record_data.category != Xtst::LibXtst::RecordInterceptDataCategory::FromServer.value
  xevent = record_data.data
  repeat = xevent[2] == 1
  next if repeat
  type = xevent[0]
  keycode = xevent[1]
  state = xevent[28]
  pp! type, keycode, state
end
fd = IO::FileDescriptor.new record.data_display.connection_number
loop do
  dpy_fd.wait_readable
  record.process_replies
end
