Now you don't need the latest Wayland installed to build with newer protocols supported, as they'll build correctly; even if your system can't use them, we can make intelligent decisions at runtime about what's available on the current machine anyhow. This also simplifies some logic and possible failure cases in the configure and CMake scripts. Fixes Bugzilla #4207.

<description summary="child surface positioner">
|
|
The xdg_positioner provides a collection of rules for the placement of a
|
|
child surface relative to a parent surface. Rules can be defined to ensure
|
|
the child surface remains within the visible area's borders, and to
|
|
specify how the child surface changes its position, such as sliding along
|
|
an axis, or flipping around a rectangle. These positioner-created rules are
|
|
constrained by the requirement that a child surface must intersect with or
|
|
be at least partially adjacent to its parent surface.
|
|
|
|
See the various requests for details about possible rules.
|
|
|
|
At the time of the request, the compositor makes a copy of the rules
|
|
specified by the xdg_positioner. Thus, after the request is complete the
|
|
xdg_positioner object can be destroyed or reused; further changes to the
|
|
object will have no effect on previous usages.
|
|
|
|
For an xdg_positioner object to be considered complete, it must have a
|
|
non-zero size set by set_size, and a non-zero anchor rectangle set by
|
|
set_anchor_rect. Passing an incomplete xdg_positioner object when
|
|
positioning a surface raises an error.

<description summary="desktop user interface surface base interface">
|
|
An interface that may be implemented by a wl_surface, for
|
|
implementations that provide a desktop-style user interface.
|
|
|
|
It provides a base set of functionality required to construct user
|
|
interface elements requiring management by the compositor, such as
|
|
toplevel windows, menus, etc. The types of functionality are split into
|
|
xdg_surface roles.
|
|
|
|
Creating an xdg_surface does not set the role for a wl_surface. In order
|
|
to map an xdg_surface, the client must create a role-specific object
|
|
using, e.g., get_toplevel, get_popup. The wl_surface for any given
|
|
xdg_surface can have at most one role, and may not be assigned any role
|
|
not based on xdg_surface.
|
|
|
|
A role must be assigned before any other requests are made to the
|
|
xdg_surface object.
|
|
|
|
The client must call wl_surface.commit on the corresponding wl_surface
|
|
for the xdg_surface state to take effect.
|
|
|
|
Creating an xdg_surface from a wl_surface which has a buffer attached or
|
|
committed is a client error, and any attempts by a client to attach or
|
|
manipulate a buffer prior to the first xdg_surface.configure call must
|
|
also be treated as errors.
|
|
|
|
For a surface to be mapped by the compositor, the following conditions
|
|
must be met: (1) the client has assigned a xdg_surface based role to the
|
|
surface, (2) the client has set and committed the xdg_surface state and
|
|
the role dependent state to the surface and (3) the client has committed a

buffer to the surface.

When a configure event is received, if a client commits the

surface in response to the configure event, then the client
|
|
must make an ack_configure request sometime before the commit
|
|
request, passing along the serial of the configure event.
|
|
|
|
For instance, for toplevel surfaces the compositor might use this
|
|
information to move a surface to the top left only when the client has
|
|
drawn itself for the maximized or fullscreen state.
|
|
|
|
If the client receives multiple configure events before it
|
|
can respond to one, it only has to ack the last configure event.
|
|
|
|
A client is not required to commit immediately after sending
|
|
an ack_configure request - it may even ack_configure several times
|
|
before its next surface commit.
|
|
|
|
A client may send multiple ack_configure requests before committing, but
|
|
only the last request sent before a commit indicates which configure

The configure event marks the end of a configure sequence. A configure

|
|
|
|
Where applicable, xdg_surface surface roles will during a configure

The app ID identifies the general class of applications to which

The compositor shell will try to group application surfaces together

A popup can be made to take an explicit grab. See xdg_popup.grab for

When the popup is dismissed, a popup_done event will be sent out, and at

The parent of an xdg_popup must be mapped (see the xdg_surface

|
client destroys the xdg_popup. This can be done by the user clicking
|
|
outside the surface, using the keyboard, or even locking the screen
|
|
through closing the lid or a timeout.
|
|
|
|
If the compositor denies the grab, the popup will be immediately
|
|
dismissed.
|
|
|
|
This request must be used in response to some sort of user action like a
|
|
button press, key press, or touch down event. The serial number of the
|
|
event should be passed as 'serial'.
|
|
|
|
The parent of a grabbing popup must either be an xdg_toplevel surface or
|
|
another xdg_popup with an explicit grab. If the parent is another
|
|
xdg_popup it means that the popups are nested, with this popup now being
|
|
the topmost popup.
|
|
|
|
Nested popups must be destroyed in the reverse order they were created
|
|
in, e.g. the only popup you are allowed to destroy at all times is the
|
|
topmost one.
|
|
|
|
When compositors choose to dismiss a popup, they may dismiss every
|
|
nested grabbing popup as well. When a compositor dismisses popups, it
|
|
will follow the same dismissing order as required from the client.
|
|
|
|
The parent of a grabbing popup must either be another xdg_popup with an
|
|
active explicit grab, or an xdg_popup or xdg_toplevel, if there are no
|
|
explicit grabs already taken.
|
|
|
|
If the topmost grabbing popup is destroyed, the grab will be returned to
|
|
the parent of the popup, if that parent previously had an explicit grab.
|
|
|
|
If the parent is a grabbing popup which has already been dismissed, this
|
|
popup will be immediately dismissed. If the parent is a popup that did
|
|
not take an explicit grab, an error will be raised.
|
|
|
|
During a popup grab, the client owning the grab will receive pointer
|
|
and touch events for all their surfaces as normal (similar to an
|
|
"owner-events" grab in X11 parlance), while the top most grabbing popup
|
|
will always have keyboard focus.
