<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.
|
|
|
|
Mapping an xdg_surface-based role surface is defined as making it
|
|
possible for the surface to be shown by the compositor. Note that
|
|
a mapped surface is not guaranteed to be visible once it is mapped.
|
|
|
|
For an xdg_surface to be mapped by the compositor, the following
|
|
conditions must be met:
|
|
(1) the client has assigned an 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
|
|
(3) the client has committed a buffer to the surface
|
|
|
|
A newly-unmapped surface is considered to have met condition (1) out
|
|
of the 3 required conditions for mapping a surface if its role surface
|
|
has not been destroyed.

<description summary="set the new window geometry">
|
|
The window geometry of a surface is its "visible bounds" from the
|
|
user's perspective. Client-side decorations often have invisible
|
|
portions like drop-shadows which should be ignored for the
|
|
purposes of aligning, placing and constraining windows.
|
|
|
|
The window geometry is double buffered, and will be applied at the
|
|
time wl_surface.commit of the corresponding wl_surface is called.
|
|
|
|
When maintaining a position, the compositor should treat the (x, y)
|
|
coordinate of the window geometry as the top left corner of the window.
|
|
A client changing the (x, y) window geometry coordinate should in
|
|
general not alter the position of the window.
|
|
|
|
Once the window geometry of the surface is set, it is not possible to
|
|
unset it, and it will remain the same until set_window_geometry is
|
|
called again, even if a new subsurface or buffer is attached.
|
|
|
|
If never set, the value is the full bounds of the surface,
|
|
including any subsurfaces. This updates dynamically on every
|
|
commit. This unset is meant for extremely simple clients.
|
|
|
|
The arguments are given in the surface-local coordinate space of
|
|
the wl_surface associated with this xdg_surface.
|
|
|
|
The width and height must be greater than zero. Setting an invalid size
|
|
will raise an error. When applied, the effective window geometry will be
|
|
the set window geometry clamped to the bounding rectangle of the
|
|
combined geometry of the surface of the xdg_surface and the associated
|
|
subsurfaces.

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

drawn itself for the maximized or fullscreen state.

If the client receives multiple configure events before it

A client is not required to commit immediately after sending

an ack_configure request - it may even ack_configure several times

A client may send multiple ack_configure requests before committing, but

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

Unmapping an xdg_toplevel means that the surface cannot be shown

The app ID identifies the general class of applications to which

For D-Bus activatable applications, the app ID is used as the D-Bus

|
The compositor shell will try to group application surfaces together
|
|
by their app ID. As a best practice, it is suggested to select app

ID's that match the basename of the application's .desktop file.

For example, "org.freedesktop.FooViewer" where the .desktop file is

"org.freedesktop.FooViewer.desktop".

border fill is undefined, but should be assumed to be in some way that
|
|
attempts to blend into the surrounding area (e.g. solid black).
|
|
|
|
If the fullscreened surface is not opaque, the compositor must make
|
|
sure that other screen content not part of the same surface tree (made
|
|
up of subsurfaces, popups or similarly coupled surfaces) are not
|
|
visible below the fullscreened surface.

After requesting that the surface should be unfullscreened, the
|
|
compositor will respond by emitting a configure event.
|
|
Whether this actually removes the fullscreen state of the client is
|
|
subject to compositor policies.
|
|
|
|
Making a surface unfullscreen sets states for the surface based on the following:
|
|
* the state(s) it may have had before becoming fullscreen
|
|
* any state(s) decided by the compositor
|
|
* any state(s) requested by the client while the surface was fullscreen
|
|
|
|
The compositor may include the previous window geometry dimensions in
|
|
the configure event, if applicable.
|
|
|
|
The client must also acknowledge the configure when committing the new
|
|
content (see ack_configure).

If you are looking to throttle redrawing when minimized, please

<event name="configure">

<description summary="suggest a surface change">
|
|
This configure event asks the client to resize its toplevel surface or
|
|
to change its state. The configured state should not be applied
|
|
immediately. See xdg_surface.configure for details.
|
|
|
|
The width and height arguments specify a hint to the window
|
|
about how its surface should be resized in window geometry
|
|
coordinates. See set_window_geometry.
|
|
|
|
If the width or height arguments are zero, it means the client
|
|
should decide its own window dimension. This may happen when the
|
|
compositor needs to configure the state of the surface but doesn't
|
|
have any information about any previous or expected dimension.
|
|
|
|
The states listed in the event specify how the width/height
|
|
arguments should be interpreted, and possibly how it should be
|
|
drawn.
|
|
|
|
Clients must send an ack_configure in response to this event. See
|
|
xdg_surface.configure and xdg_surface.ack_configure for details.

the user clicking the close button in client-side decorations,

if your application has any.
|

This is only a request that the user intends to close the

<description summary="short-lived, popup surfaces for menus">
|
|
A popup surface is a short-lived, temporary surface. It can be used to
|
|
implement for example menus, popovers, tooltips and other similar user
|
|
interface concepts.
|
|
|
|
A popup can be made to take an explicit grab. See xdg_popup.grab for
|
|
details.
|
|
|
|
When the popup is dismissed, a popup_done event will be sent out, and at
|
|
the same time the surface will be unmapped. See the xdg_popup.popup_done
|
|
event for details.
|
|
|
|
Explicitly destroying the xdg_popup object will also dismiss the popup and
|
|
unmap the surface. Clients that want to dismiss the popup when another
|
|
surface of their own is clicked should dismiss the popup using the destroy
|
|
request.
|
|
|
|
A newly created xdg_popup will be stacked on top of all previously created
|
|
xdg_popup surfaces associated with the same xdg_toplevel.
|
|
|
|
The parent of an xdg_popup must be mapped (see the xdg_surface
|
|
description) before the xdg_popup itself.
|
|
|
|
The client must call wl_surface.commit on the corresponding wl_surface
|
|
for the xdg_popup state to take effect.

<description summary="make the popup take an explicit grab">
|
|
This request makes the created popup take an explicit grab. An explicit
|
|
grab will be dismissed when the user dismisses the popup, or when the
|
|
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.

Reposition an already-mapped popup. The popup will be placed given the

by the previous positioner will be discarded.

The passed token will be sent in the corresponding

xdg_popup.repositioned event. The new popup position will not take

effect until the corresponding configure event is acknowledged by the

client. See xdg_popup.repositioned for details. The token itself is

opaque, and has no other special meaning.

If the popup is repositioned in response to a configure event for its

If the popup is repositioned together with a parent that is being
