This allows clients to change the size and rotation of the +root window of a screen, along with the ability to reflect the screen +about either axis (if supported by the implementation). Rotation and +reflection may be implemented by software and may result in slower +performance if rotation and reflection are implemented in this fashion +(as are all implementations as of October 2002). +.PP +The Xrandr library does some minimal caching to avoid roundtrips to +provide clients frequently used information. See "The X Resize and +Rotate Extension" for a detailed description; also note that depth +switching, as described in the document is not implemented, and may +(or may not) ever be implemented, as display memory is growing rapidly, +and toolkits are already beginning to support migration, mitigating the +need for depth switching. If it is implemented in the future, we +expect to do so via an upward compatible extension to the +current library/protocol; functionality described here should continue +to work. +.PP +Rotation and reflection and how they interact can be confusing. In +Randr, the coordinate system is rotated in a counter-clockwise +direction relative to the normal orientation. Reflection is along the +window system coordinate system, not the physical screen X and Y axis, +so that rotation and reflection do not interact. The other way to +consider reflection is to is specified in the "normal" orientation, +before rotation, if you find the other way confusing. +.PP +The +.B XRRScreenChangeNotify +event is sent to clients that ask to be informed whenever the root window +configuration changes. Configuration changes may include resolution, +physical size, subpixel order (see XRender(3)), and rotation. Note +that changes to any or all of these could occur due to external events +(user control in the X server, a different monitor/flat panel display +being hot-plugged) and is not only the result of a protocol/library +request to the X server. +.PP +Additionally, to eliminate a potential race condition, +this event may be generated +immediately upon selecting for notification if the screen has changed +since the client of Xrandr connected to the X server, to enable +reliable screen resolution changing when a user may log in and +change the configuration while one or many clients are starting up. +.PP +.B Xlib notification +.PP +Clients must call back into Xlib using +.B XRRUpdateConfiguration +when screen configuration change notify events are generated +(or root window configuration changes occur, to update Xlib's +view of the resolution, size, rotation, reflection or subpixel order. +Generally, toolkits will perform this operation on behalf of applications; +we did not want to change display structure data behind the back of toolkits, +as in multithreaded clients, various race conditions might occur. +Toolkits should provide clients some mechanism for notification of +screen change, of course. + +.SH FUNCTIONS +There are two classes of interfaces: those which can be safely called +even if RandR is not implemented on a screen (to make common idioms not +dependent on the server having support), and those which will return +errors if the extension is not present. +.PP +.B XRRRotations +returns both the possible set of rotations/reflections supported +(as a bitmask) as the value of the function, along with the current +rotation/reflection of the screen. +.PP +.B XRRSizes +returns the size and a pointer to the current sizes supported by +the specified screen. The first size specified is the default size +of the server. If RandR is not supported, it returns 0 for +the number of sizes. +.PP +.B XRRRates +returns a pointer to a the rates supported by the specified size. +If RandR is not supported, it returns 0 for the number of rates. +.PP +.B XRRTimes +returns the time last reported by the server along with the +timestamp the last configuration changed. +If the configuration has changed since the client last updated +its view of the server time, requests to change the configuration +will fail until the client has an up to date timestamp. +.PP +.B XRRRootToScreen +returns the screen number given a root window (for example, from +an \fBXRRScreenChangeNotifyEvent\fI. +.PP +The rest of the functions will fail if applied to screens not +implementing the RandR extension. +.B XRRSetScreenConfig +sets the screen size and rotation and reflection to the desired +values on the screen specified by \fIdraw\fP, or returns a +.B BadValue +error. +\fIsize_index\fP specifies which size configuration is to be used, +\fIrotation\fP specifies which rotation or reflection is to +be used (or a +.B BadValue +error is returned). +The \fItimestamp\fP is used by the server to make sure the client +has up to date configuration information. Status is returned +to indicate success or failure; a client must refresh its configuration +information if it fails and try the call again (by calling +\fBXRRGetScreenInfo\fP). +.PP +.B XRRSetScreenConfigAndRate +like +.B XRRSetScreenConfig +but also set the refresh rate. If specified rate is not supported a +.B BadValue +error is returned. +.PP +.B XRRConfigRotations, +.B XRRConfigSizes, +.B XRRConfigCurrentConfiguration, +.B XRRConfigTimes, +.B XRRConfigRates, +and +.B XRRConfigCurrentRate +are used to get specific configuration information out of a screen +configuration. +.PP +.B XRRGetScreenInfo +Returns a screen configuration for later use; the information is +private to the library. +Call +.B XRRFreeScreenConfigInfo +to free this information when you are finished with it. +It forces a round trip to the server. + +Other functions include: +.B XRRQueryExtension +which returns the event and error base codes, +.B XRRQueryVersion +, which returns the current version of the extension (this information +is cached by the library). +.SH RESTRICTIONS +.B Xrandr +will remain upward compatible after the current 1.0 release. +.SH AUTHOR +Jim Gettys, and Keith Packard, HP. + diff --git a/nx-X11/lib/Xrandr/Xrandrint.h b/nx-X11/lib/Xrandr/Xrandrint.h new file mode 100644 index 000000000..78a8fcf11 --- /dev/null +++ b/nx-X11/lib/Xrandr/Xrandrint.h @@ -0,0 +1,87 @@ +/* + * $XFree86: xc/lib/Xrandr/Xrandrint.h,v 1.2 2001/06/07 15:33:43 keithp Exp $ + * + * + * Copyright © 2000, Compaq Computer Corporation, + * Copyright © 2002, Hewlett Packard, Inc. + * + * Permission to use, copy, modify, distribute, and sell this software and its + * documentation for any purpose is hereby granted without fee, provided that + * the above copyright notice appear in all copies and that both that + * copyright notice and this permission notice appear in supporting + * documentation, and that the name of Compaq or HP not be used in advertising + * or publicity pertaining to distribution of the software without specific, + * written prior permission.
