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 (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. + + + + + 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 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. + + A positive value is only meaningful if the surface is anchored to an + edge, rather than a corner. The zone is the number of surface-local + coordinates from the edge that are considered 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 excluzive zone. If set to -1, the surface + indicates that it would not like to be moved to accomodate 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. + + + + + + + + + + Set to 1 to request that the seat send keyboard events to this layer + surface. For layers below the shell surface layer, the seat will use + normal focus semantics. For layers above the shell surface layers, the + seat will always give exclusive keyboard focus to the top-most layer + which has keyboard interactivity set to true. + + 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. + + Events 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. + + + + + + + + + + + + + + + + + diff --git a/swaybg/main.c b/swaybg/main.c index 2fdd4220b..94e982282 100644 --- a/swaybg/main.c +++ b/swaybg/main.c @@ -1,20 +1,11 @@ -#include "wayland-desktop-shell-client-protocol.h" +#include #include #include #include -#include -#include -#include #include -#include "client/window.h" -#include "client/registry.h" -#include "client/cairo.h" -#include "log.h" -#include "list.h" -#include "util.h" - -list_t *surfaces; -struct registry *registry; +#include +#include +#include enum scaling_mode { SCALING_MODE_STRETCH, @@ -24,21 +15,11 @@ enum scaling_mode { SCALING_MODE_TILE, }; -void sway_terminate(int exit_code) { - int i; - for (i = 0; i < surfaces->length; ++i) { - struct window *window = surfaces->items[i]; - window_teardown(window); - } - list_free(surfaces); - registry_teardown(registry); - exit(exit_code); -} - bool is_valid_color(const char *color) { int len = strlen(color); if (len != 7 || color[0] != '#') { - sway_log(L_ERROR, "%s is not a valid color for swaybg.
