The central design choice that has driven development is to hide +the complexity of X wherever possible but expose it when necessary. + +For example, the xevent package provides an implementation of an X event loop +that acts as a dispatcher to event handlers set up with the xevent, keybind and +mousebind packages. At the same time, the event queue is exposed and can be +modified using xevent.Peek and xevent.DequeueAt. + +Sub-packages + +The xgbutil package is considerably small, and only contains some type +definitions and the initial setup for an X connection.

Indeed, each +method has only a single comment associated with it: the EWMH property name. + +The idea is to +provide a consistent interface to use all facilities described in the EWMH +spec: http://standards.freedesktop.org/wm-spec/wm-spec-latest.html. + +Naming scheme + +Using "_NET_ACTIVE_WINDOW" as an example, +functions "ActiveWindowGet" and "ActiveWindowSet" get and set the +property, respectively. Both of these functions exist for most EWMH +properties. Additionally, some EWMH properties support sending a client +message event to request the window manager to perform some action. In the +case of "_NET_ACTIVE_WINDOW", this request is used to set the active +window. + +These sorts of functions end in "Req". So for "_NET_ACTIVE_WINDOW", +the method name is "ActiveWindowReq". Moreover, most requests include +various parameters that don't need to be changed often (like the source +indication). Thus, by default, functions ending in "Req" force these to +sensible defaults. If you need access to all of the parameters, use the +corresponding "ReqExtra" method. So for "_NET_ACTIVE_WINDOW", that would +be "ActiveWindowReqExtra". (If no "ReqExtra" method exists, then the +"Req" method covers all available parameters.) + +This naming scheme has one exception: if a property's only use is through +sending an event (like "_NET_CLOSE_WINDOW"), then the name will be +"CloseWindow" for the short-hand version and "CloseWindowExtra" +for access to all of the parameters. (Since there is no "_NET_CLOSE_WINDOW" +property, there is no need for "CloseWindowGet" and "CloseWindowSet" +functions.) + +For properties that store more than just a simple integer, name or list +of integers, structs have been created and exposed to organize the +information returned in a sensible manner. For example, the +"_NET_DESKTOP_GEOMETRY" property would typically return a slice of integers +of length 2, where the first integer is the width and the second is the +height. Xgbutil will wrap this in a struct with the obvious members. These +structs are documented. + +Finally, functions ending in "*Set" are typically only used when setting +properties on clients *you've* created or when the window manager sets +properties. Thus, it's unlikely that you should use them unless you're +creating a top-level client or building a window manager. + +Functions ending in "Get" or "Req[Extra]" are commonly used. + +N.B.

attaching callback +functions to X events, and an implementation of an X event loop. + +The X event loop + +One of the biggest conveniences offered by xgbutil is its event handler system. +That is, the ability to attach an arbitrary callback function to any X event. +In order for such things to work, xgbutil needs to control the main X event +loop and act as a dispatcher for all event handlers created by you. + +To run the X event loop, use xevent.Main or xevent.MainPing. The former +runs a normal event loop in the current goroutine and processes events. The +latter runs the event loop in a new goroutine and returns a pingBefore and +a pingAfter channel. The pingBefore channel is sent a benign value right before +an event is dequeued, and the pingAfter channel is sent a benign value right +after after all callbacks for that event have finished execution. These +synchronization points in the main event loop can be combined with a 'select' +statement to process data from other input sources. An example of this is given +in the documentation for the MainPing function. A complete example called +multiple-source-event-loop can also be found in the examples directory of the +xgbutil package. + +To quit the main event loop, you may use xevent.Quit, but there is nothing +inherently wrong with stopping dead using os.Exit. xevent.Quit is provided for +your convenience should you need to run any clean-up code after the main event +loop returns. + +The X event queue + +xgbutil's event queue contains values that are either events or errors. (Never +both and never neither.) Namely, errors are received in the event loop from +unchecked requests. (Errors generated by checked requests are guaranteed to be +returned to the caller and are never received in the event loop.) Also, a +default error handler function can be set with xevent.ErrorHandlerSet. + +To this end, xgbutil's event queue can be inspected. This is advantageous when +information about what events will be processed in the future could be helpful +(i.e., if there is an UnmapNotify event waiting to be processed.) The event +queue can also be manipulated to facilitate event compression. (Two events that +are common candidates for compression are ConfigureNotify and MotionNotify.) + +Detach events + +Whenever a window can no longer receive events (i.e., when it is destroyed), +all event handlers related to that window should be detached. (If this is +omitted, then Go's garbage collector will not be able to reuse memory occupied +by the now-unused event handlers for that window.) Moreover, its possible that +a window id can be reused after it has been discarded, which could result in +odd behavior in your application. + +To detach a window from all event handlers in the xevent package, use +xevent.Detach. If you're also using the keybind and mousebind packages, you'll +need to call keybind.Detach and mousebind.Detach too. So to detach your window +from all possible event handlers in xgbutil, use something like: + + xevent.Detach(XUtilValue, your-window-id) + keybind.Detach(XUtilValue, your-window-id) + mousebind.Detach(XUtilValue, your-window-id) + +Quick example + +A small example that shows how to respond to ConfigureNotify events sent to +your-window-id. + + xevent.ConfigureNotifyFun( + func(X *xgbutil.XUtil, e xevent.ConfigureNotifyEvent) { + fmt.Printf("(%d, %d) %dx%d\n", e.X, e.Y, e.Width, e.Height) + }).Connect(XUtilValue, your-window-id) + +More examples + +The xevent package is used in several of the examples in the examples directory +in the xgbutil package. +*/ +package xevent diff --git a/vendor/github.com/BurntSushi/xgbutil/xevent/eventloop.go b/vendor/github.com/BurntSushi/xgbutil/xevent/eventloop.go new file mode 100644 index 0000000..458f391 --- /dev/null +++ b/vendor/github.com/BurntSushi/xgbutil/xevent/eventloop.go @@ -0,0 +1,291 @@ +package xevent + +/* +xevent/eventloop.go contains code that implements a main X event loop. + +Namely, it provides facilities to read new events into xevent's event queue, +run a normal main event loop and run a main event loop that pings a channel +each time an event is about to be dequeued.
