Such surfaces are assigned to a "layer" of the output and + rendered with a defined z-depth respective to each other. They may also be + anchored to the edges and corners of a screen and specify input handling + semantics. This interface should be suitable for the implementation of + many desktop shell components, and a broad number of other applications + that interact with the desktop. + + + + + Create a layer surface for an existing surface. This assigns the role of + layer_surface, or raises a protocol error if another role is already + assigned. + + Creating a layer 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 layer_surface.configure call + must also be treated as errors. + + Clients can specify a namespace that defines the purpose of the layer + surface. + + + + + + + + + + + + + + + + + + These values indicate which layers a surface can be rendered in. They + are ordered by z depth, bottom-most first. Traditional shell surfaces + will typically be rendered between the bottom and top layers. + Fullscreen shell surfaces are typically rendered at the top layer. + Multiple surfaces can share a single layer, and ordering within a + single layer is undefined. + + + + + + + + + + + + An interface that may be implemented by a wl_surface, for surfaces that + are designed to be rendered as a layer of a stacked desktop-like + environment. + + Layer surface state (anchor, exclusive zone, margin) is double-buffered. + Protocol requests modify the pending state, as opposed to the current + state in use by the compositor. The wl_surface.commit request atomically + applies all pending state, replacing the current state. After commit, the + new pending state is as documented for each related request. + + + + + Requests that the compositor anchor the surface to the specified edges + and corners. If two orthoginal edges are specified (e.g. 'top' and + 'left'), then the anchor point will be the intersection of the edges + (e.g. the top left corner of the output); otherwise the anchor point + will be centered on that edge, or in the center if none is specified. + + Anchor is double-buffered, see wl_surface.commit. + + + + + + + Requests that the compositor avoids occluding an area of the surface + with other surfaces. The compositor's use of this information is + implementation-dependent - do not assume that this region will not + actually be occluded. + + This value is only meaningful if the surface is anchored to an edge, + rather than a corner. The zone is the number of pixels from the edge + that are considered exclusive. + + Exclusive zone is double-buffered, see wl_surface.commit. + + + + + + + Requests that the surface be placed some distance away from the anchor + point on the output, in pixels. Setting this value for edges you are + not anchored to has no effect. + + Margin is double-buffered, see wl_surface.commit. + + + + + + + + + + This assigns an xdg_popup's parent to this layer_surface. This popup + should have been created via xdg_surface::get_popup with the parent set + to NULL, and this request must be invoked before committing the popup's + initial state. + + See the documentation of xdg_popup for more details about what an + xdg_popup is and how it is used. + + + + + + + This creates a layer input for this layer surface. This can be used to + control input semantics for the layer surface on the specified wl_seat. + + + + + + + + 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. + + 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 + event the client really is responding to. + + + + + + + This request destroys the layer surface. + + + + + + The configure event asks the client to resize its surface. + + Clients should arrange their surface for the new states, and then send + an ack_configure request with the serial sent in this configure event at + some point before committing the new surface. + + The client is free to dismiss all but the last configure event it + received. + + The width and height arguments specify the size of the window in + surface-local coordinates. + + The size is a hint, in the sense that the client is free to ignore it if + it doesn't resize, pick a smaller size (to satisfy aspect ratio or + resize in steps of NxM pixels). If the client picks a smaller size and + is anchored to two opposite anchors (e.g. 'top' and 'bottom'), the + surface will be centered on this axis. + + If the width or height arguments are zero, it means the client should + decide its own window dimension. + + + + + + + + + + + + + + + + + + + + + + Clients can use this interface to specify input semantics for a layer + surface on a given seat. By default, layer surfaces are considered + non-interactive by seats, and will not participate in their focus + semantics or receive input events for them. + + Input state is double-buffered. Protocol requests modify the pending + state, as opposed to the current state in use by the compositor. The + wl_surface.commit request for the associated layer surface atomically + applies all pending state, replacing the current state. After commit, the + new pending state is as documented for each related request. + + + + + Requests that the seat send input events for the specified input devices + to this layer surface. + + Positional events (pointer and touch) will only be sent if the layer + surface is the top-most interactive surface, and only when the position + of these events are relative to the surface. Enter and leave events will + be signalled normally in these cases. + + Keyboard events will treat the layer surface as the only focused surface + on the seat. Upon requesting keyboard events, the layer surface will + receive a keyboard enter event.
