(NoteLocalSelectionBody, NoteLocalSelectionFooter): Extract selection-generic code from XLNoteLocalSelection. (XLNoteLocalSelection): Reimplement in terms of the above two macros. (XLNoteLocalPrimary, GetPrimaryCallback): New functions. (XLInitXData): Select for selection input from XA_PRIMARY as well. * xdg_surface.c (AckConfigure): Improve debug code. (Commit): Clear that flag. (NoteBounds): If that flag is set, return. (HandleFreeze): Assume a configure event will arrive after a sync request; set flags accordingly. (XLGetXdgSurface): Add HandleFreeze. (XLXdgRoleSendConfigure): Clear some flags and add new state flag `StateWaitingForAckCommit'. Set it. It means that no commit has yet happened after ack_configure. (XLXdgRoleNoteRejectedConfigure): New function. Clear flags if the configure event following _NET_WM_SYNC_REQUEST was rejected. * xdg_toplevel.c (struct _XdgToplevel): New state flags StatePendingResize, StateConfigureSize, StatePendingConfigureStates. New field `configuration_timer'. (batch_state_changes): New flag. (DestroyBacking): Clear configuration timer. (NoteConfigureTime): New function; apply queued state changes. (HandleWmStateChange, HandleConfigureEvent): By default, queue state changes and configure events so they can be applied in one go. (Unmap): Clear delayed configuration timer. (Commit, CommitInsideFrame, PostResize): Improve movement delta adjustment for min_width and min_height, and queue pending motion for after ack_configure. (XLInitXdgToplevels): Set `batch_state_changes' depending on the DIRECT_STATE_CHANGES' environment variable.

This is a tool for running Wayland applications on an X server,
|
|
preferably with a compositing manager running.
|
|
|
|
It is not yet complete. What is not yet implemented includes support
|
|
for touchscreens, input methods, device switching in dmabuf feedback,
|
|
and the viewporter protocol extension.
|
|
|
|
There are also problems with output reporting in subsurfaces.
|
|
|
|
It is not portable to systems other than recent versions of GNU/Linux
|
|
running the X.Org server 1.20 or later, and has not been tested on
|
|
window (and compositing) managers other than GNOME Shell.
|
|
|
|
It will not work very well unless the compositing manager supports the
|
|
EWMH frame synchronization protocol.
|
|
|
|
Building and running this tool requires the following X protocol
|
|
extensions:
|
|
|
|
Nonrectangular Window Shape Extension, version 1.1 or later
|
|
MIT Shared Memory Extension, version 1.2 or later
|
|
X Resize, Rotate and Reflect Extension, version 1.3 or later
|
|
(this will soon be 1.4, once support for multiple GPU
|
|
systems is fully implemented)
|
|
X Synchronization Extension, version 1.0 or later
|
|
X Rendering Extension, version 1.2 or later
|
|
X Input Extension, version 2.3 or later
|
|
Direct Rendering Interface 3, version 1.2 or later
|
|
X Fixes Extension, version 1 or later
|
|
|
|
In addition, it requires Xlib to be built with the XCB transport, and
|
|
the XCB bindings for MIT-SHM and DRI3 to be available.
|
|
|
|
The following Wayland protocols are implemented to a more-or-less
|
|
complete degree:
|
|
|
|
'wl_output', version: 2
|
|
'wl_compositor', version: 5
|
|
'wl_shm', version: 1
|
|
'xdg_wm_base', version: 5
|
|
'wl_subcompositor', version: 1
|
|
'wl_seat', version: 7
|
|
'wl_data_device_manager', version: 3
|
|
'zwp_linux_dmabuf_v1', version: 4
|
|
'zwp_primary_selection_device_manager_v1', version: 1
|
|
|
|
With the main caveat being that zwp_linux_dmabuf_v1 has no real
|
|
support for multiple-provider setups (help wanted).
|
|
|
|
Window decorations are also not supported, even though they fit in
|
|
nicely with X window management.
|
|
|
|
It would also be nice to have pinch gesture support.
|
|
|
|
This directory is organized as follows:
|
|
|
|
Imakefile - the top level Makefile template
|
|
libraries.def - files for libraries that don't provide Imakefiles
|
|
*.xml - Wayland protocol definition source
|
|
*.c, *.h - C source code
|
|
|
|
Building the source code is simple, provided that you have the
|
|
necessary libwayland-server library, wayland-scanner, pixman, XCB, and
|
|
X extension libraries installed:
|
|
|
|
xmkmf # to generate the Makefile
|
|
make # to build the binary
|
|
|
|
Running the binary should be simple as well:
|
|
|
|
./12to11
|
|
|
|
Wayland programs will then run as regular X windows.
