An * application can have multiple clients (like for dialogs) or none at all * (like command line applications). Clients are usually grouped by classes. A * class is the name used by X11 to help window manager distinguish between * window and write rules for them. See the `xprop` command line application. A * client also have a `type` and `size_hints` used to define its behavior. * * ![Client geometry](../images/client_geo.svg) * * The client `:geometry()` return a table with *x*, *y*, *width* and *height*. * The area returned **exclude the border width**. All clients also have a * `shape_bounding` and `shape_clip` used to "crop" the client content. Finally, * each clients can have titlebars (see `awful.titlebar`). * * Furthermore to the classes described here, one can also use signals as * described in @{signals} and X properties as described in @{xproperties}. * * Some signal names are starting with a dot. These dots are artefacts from * the documentation generation, you get the real signal name by * removing the starting dot. * * Accessing client objects can be done in multiple ways depending on the * context. To get the current focused client, use: * * local c = client.focus * * if c then * -- do something * end * * To get a list of all clients, use `client:get` * * for _, c in ipairs(client.get()) do * -- do something * end * * To get a callback when a new client is added, use the `manage` signal: * * client.connect_signal("manage", function(c) * -- do something * end * * To be notified a property changed in a client, use: * * client.connect_signal("property::name", function(c) * -- do something * end * * To be notified when a property change for a specific client (assuming it is * stored in the variable `c`), use: * * c:connect_signal("property::name", function() * -- do something * end * * To get all the clients for a screen, use either `screen.clients` or * `screen.tiled_clients` * * @author Julien Danjou <julien@danjou.info> * @copyright 2008-2009 Julien Danjou * @release @AWESOME_VERSION@ * @classmod client */ #include "objects/client.h" #include "common/atoms.h" #include "common/xutil.h" #include "event.h" #include "ewmh.h" #include "objects/drawable.h" #include "objects/screen.h" #include "objects/tag.h" #include "property.h" #include "spawn.h" #include "systray.h" #include "xwindow.h" #include "math.h" #include #include #include /** Client class. * * @table object */ /** * The focused `client` or nil (in case there is none). * * @tfield client focus */ /** * The X window id. * * **Signal:** * * * *property::window* * * @property window * @param string */ /** * The client title. * * **Signal:** * * * *property::name* * * @property name * @param string */ /** * True if the client does not want to be in taskbar. * * **Signal:** * * * *property::skip\_taskbar* * * @property skip_taskbar * @param boolean */ /** * The window type. * * Valid types are: * * * **desktop**: The root client, it cannot be moved or resized. * * **dock**: A client attached to the side of the screen. * * **splash**: A client, usually without titlebar shown when an application starts. * * **dialog**: A dialog, see `transient_for`. * * **menu**: A context menu. * * **toolbar**: A floating toolbar. * * **utility**: * * **dropdown_menu**: A context menu attached to a parent position. * * **popup_menu**: A context menu. * * **notification**: A notification popup. * * **combo**: A combobox list menu. * * **dnd**: A drag and drop indicator. * * **normal**: A normal application main window. * * More information can be found [here](https://specifications.freedesktop.org/wm-spec/wm-spec-latest.html#idm140200472629520) * * **Signal:** * * * *property::type* * * @property type * @param string */ /** * The client class. * * If the client has multiple classes, the first one is used. * * To get a client class from the command line, use te `xprop` command. * * **Signal:** * * * *property::class* * * @property class * @param string */ /** * The client instance. * * **Signal:** * * * *property::instance* * * @property instance * @param string */ /** * The client PID, if available. * * **Signal:** * * * *property::pid* * * @property pid * @param number */ /** * The window role, if available. * * **Signal:** * * * *property::role* * * @property role * @param string */ /** * The machine client is running on. * * **Signal:** * * * *property::machine* * * @property machine * @param string */ /** * The client name when iconified. * * **Signal:** * * * *property::icon\_name* * * @property icon_name * @param string */ /** * The client icon. * * **Signal:** * * * *property::icon* * * @property icon * @param surface */ /** * Client screen. * * **Signal:** * * * *property::screen* * * @property screen * @param screen */ /** * Define if the client must be hidden, i.e. never mapped, * invisible in taskbar. * * **Signal:** * * * *property::hidden* * * @property hidden * @param boolean */ /** * Define it the client must be iconify, i.e. only visible in * taskbar. * * **Signal:** * * * *property::minimized* * * @property minimized * @param boolean */ /** * Honor size hints, e.g. respect size ratio. * * For example, a terminal such as `xterm` require the client size to be a * multiple of the character size.
