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. - - After creating a layer_surface object and setting it up, the client - must perform an initial commit without any buffer attached. - The compositor will reply with a layer_surface.configure event. - The client must acknowledge it and is then allowed to attach a buffer - to map the surface. - - You may pass NULL for output to allow the compositor to decide which - output to use. Generally this will be the one that the user most - recently interacted with. - - 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. - - - - - - - - - - - - - This request indicates that the client will not use the layer_shell - object any more. Objects that have been created through this instance - are not affected. - - - - - - - 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 (layer, size, anchor, exclusive zone, - margin, interactivity) is double-buffered, and will be applied at the - time wl_surface.commit of the corresponding wl_surface is called. - - Attaching a null buffer to a layer surface unmaps it. - - Unmapping a layer_surface means that the surface cannot be shown by the - compositor until it is explicitly mapped again. The layer_surface - returns to the state it had right after layer_shell.get_layer_surface. - The client can re-map the surface by performing a commit without any - buffer attached, waiting for a configure event and handling it as usual. - - - - - Sets the size of the surface in surface-local coordinates. The - compositor will display the surface centered with respect to its - anchors. - - If you pass 0 for either value, the compositor will assign it and - inform you of the assignment in the configure event. You must set your - anchor to opposite edges in the dimensions you omit; not doing so is a - protocol error. Both values are 0 by default. - - Size is double-buffered, see wl_surface.commit. - - - - - - - - Requests that the compositor anchor the surface to the specified edges - and corners. If two orthogonal 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 with other - surfaces. The compositor's use of this information is - implementation-dependent - do not assume that this region will not - actually be occluded. - - A positive value is only meaningful if the surface is anchored to one - edge or an edge and both perpendicular edges. If the surface is not - anchored, anchored to only two perpendicular edges (a corner), anchored - to only two parallel edges or anchored to all edges, a positive value - will be treated the same as zero. - - A positive zone is the distance from the edge in surface-local - coordinates to consider exclusive. - - Surfaces that do not wish to have an exclusive zone may instead specify - how they should interact with surfaces that do. If set to zero, the - surface indicates that it would like to be moved to avoid occluding - surfaces with a positive exclusive zone. If set to -1, the surface - indicates that it would not like to be moved to accommodate for other - surfaces, and the compositor should extend it all the way to the edges - it is anchored to. - - For example, a panel might set its exclusive zone to 10, so that - maximized shell surfaces are not shown on top of it. A notification - might set its exclusive zone to 0, so that it is moved to avoid - occluding the panel, but shell surfaces are shown underneath it. A - wallpaper or lock screen might set their exclusive zone to -1, so that - they stretch below or over the panel. - - The default value is 0. - - 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 surface-local coordinates. Setting this value - for edges you are not anchored to has no effect. - - The exclusive zone includes the margin. - - Margin is double-buffered, see wl_surface.commit. - - - - - - - - - - Types of keyboard interaction possible for layer shell surfaces. The - rationale for this is twofold: (1) some applications are not interested - in keyboard events and not allowing them to be focused can improve the - desktop experience; (2) some applications will want to take exclusive - keyboard focus. - - - - - This value indicates that this surface is not interested in keyboard - events and the compositor should never assign it the keyboard focus. - - This is the default value, set for newly created layer shell surfaces. - - This is useful for e.g. desktop widgets that display information or - only have interaction with non-keyboard input devices. - - - - - Request exclusive keyboard focus if this surface is above the shell surface layer. - - For the top and overlay layers, the seat will always give - exclusive keyboard focus to the top-most layer which has keyboard - interactivity set to exclusive. If this layer contains multiple - surfaces with keyboard interactivity set to exclusive, the compositor - determines the one receiving keyboard events in an implementation- - defined manner. In this case, no guarantee is made when this surface - will receive keyboard focus (if ever). - - For the bottom and background layers, the compositor is allowed to use - normal focus semantics. - - This setting is mainly intended for applications that need to ensure - they receive all keyboard events, such as a lock screen or a password - prompt. - - - - - This requests the compositor to allow this surface to be focused and - unfocused by the user in an implementation-defined manner. The user - should be able to unfocus this surface even regardless of the layer - it is on. - - Typically, the compositor will want to use its normal mechanism to - manage keyboard focus between layer shell surfaces with this setting - and regular toplevels on the desktop layer (e.g. click to focus). - Nevertheless, it is possible for a compositor to require a special - interaction to focus or unfocus layer shell surfaces (e.g. requiring - a click even if focus follows the mouse normally, or providing a - keybinding to switch focus between layers). - - This setting is mainly intended for desktop shell components (e.g. - panels) that allow keyboard interaction. Using this option can allow - implementing a desktop shell that can be fully usable without the - mouse. - - - - - - - Set how keyboard events are delivered to this surface. By default, - layer shell surfaces do not receive keyboard events; this request can - be used to change this. - - This setting is inherited by child surfaces set by the get_popup - request. - - Layer surfaces receive pointer, touch, and tablet events normally. If - you do not want to receive them, set the input region on your surface - to an empty region. - - Keyboard interactivity 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. - - - - - - - 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. - - - - - - - - - The closed event is sent by the compositor when the surface will no - longer be shown. The output may have been destroyed or the user may - have asked for it to be removed. Further changes to the surface will be - ignored. The client should destroy the resource after receiving this - event, and create a new surface if they so choose. - - - - - - - - - - - - - - - - - - - - - - Change the layer that the surface is rendered on. - - Layer is double-buffered, see wl_surface.commit. - - - - - diff --git a/wayland/protocols/xdg-shell.c b/wayland/protocols/xdg-shell.c deleted file mode 100644 index 03826cd..0000000 --- a/wayland/protocols/xdg-shell.c +++ /dev/null @@ -1,183 +0,0 @@ -/* Generated by wayland-scanner 1.22.0 */ - -/* - * Copyright © 2008-2013 Kristian Høgsberg - * Copyright © 2013 Rafael Antognolli - * Copyright © 2013 Jasper St. Pierre - * Copyright © 2010-2013 Intel Corporation - * Copyright © 2015-2017 Samsung Electronics Co., Ltd - * Copyright © 2015-2017 Red Hat Inc. - * - * Permission is hereby granted, free of charge, to any person obtaining a - * copy of this software and associated documentation files (the "Software"), - * to deal in the Software without restriction, including without limitation - * the rights to use, copy, modify, merge, publish, distribute, sublicense, - * and/or sell copies of the Software, and to permit persons to whom the - * Software is furnished to do so, subject to the following conditions: - * - * The above copyright notice and this permission notice (including the next - * paragraph) shall be included in all copies or substantial portions of the - * Software. - * - * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR - * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, - * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
