-
-1. Overview
-
- The client-to-server DMX extension to the X protocol (DMX) provides
- normal client applications with the ability to determine information
- about the characteristics of the Xdmx server and the back-end X
- servers that DMX is using.
-
- The name for this extension is "DMX".
-
-
-
-2. Syntactic conventions
-
- This document uses the same syntactic conventions requests and data
- types as [X11R6.4].
-
-
-
-3. Data types
-
- No new data types are defined by this extension. All data types
- referenced in this document are defined in [X11R6.4].
-
-
-
-4. Requests
-
- DMXQueryVersion
- ==>
- majorVersion: CARD32
- minorVersion: CARD32
- patchVersion: CARD32
-
- Errors: None
-
- The protocol this extension actually supports is indicated by
- majorVersion and minorVersion (patchVersion indicates the
- patchlevel and is for informational purposes only).
-
- Any incompatible changes to the protocol should be indicated by
- incrementing majorVersion.
-
- Small, upward-compatible changes should be indicated by incrementing
- minorVersion.
-
- Servers that support the protocol defined in this document will
- return a majorVersion of 2 and a minorVersion of 2.
-
- (Version 1.5 was the last version in the 1.x series; version 2.0 was
- a testing version that was poorly defined.)
-
-
-
- DMXSync
- ==>
- status: CARD32
-
- Errors: None
-
- This request was first supported in version 1.5 of this protocol.
- The status field in the reply was introduced in version 2.0 of this
- protocol. Since the status field is ignored, no changes to the
- underlying protocol were required.
-
- This request flushes all pending protocol requests between the Xdmx
- server and each back-end X server. It is used by clients that
- talk directly to back-end X servers to ensure that all pending Xdmx
- requests have reached all back-end servers and have been processed
- by those servers.
-
- The value of status is always 0.
-
-
-
- DMXForceWindowCreation
- window: CARD32
- ==>
- status: CARD32
-
- Errors: Window
-
- This request was first supported in version 1.2 of this protocol.
- This request was changed to have a reply in version 2.0 of this
- protocol. The old version of this request was deprecated and will
- return BadImplementation.
-
- When using the lazy window creation optimization, windows are not
- created on the back-end X servers until they are required. This
- request forces the immediate creation of the window requested.
-
- The value of status is always 0.
-
-
-
-
- DMXGetScreenCount
- ==>
- screenCount: CARD32
-
- Errors: None
-
- This request returns the number of screens that the Xdmx server
- controls. Since a DMX screen usually fills all of the available
- area on a back-end server, there is usually a one-to-one
- correspondence between DMX screens and backend servers. However, it
- is also possible for a DMX screen to cover only part of the
- available area on a back-end server, and for more than one DMX
- screen to occupy different parts of the visible area on the same
- back-end server.
-
- A DMX screen may be managed as a regular X screen in the Xdmx server
- or may be joined with other DMX screens using Xinerama.
-
-
-
- DMXGetScreenAttributes
- physicalScreen: CARD32
- ==>
- displayName: STRING8
- logicalScreen: CARD32
- screenWindowWidth: CARD16
- screenWindowHeight: CARD16
- screenWindowXoffset: INT16
- screenWindowYoffset: INT16
- rootWindowWidth: CARD16
- rootWindowHeight: CARD16
- rootWindowXoffset: INT16
- rootWindowYoffset: INT16
- rootWindowXorigin: INT16
- rootWindowYorigin: INT16
-
- Errors: Value
-
- This request is new in version 2.0 of this protocol. The old
- DMXGetScreenInformation request is deprecated and will now return
- BadImplementation.
-
- This request returns attributes about a single DMX screen.
-
- The physicalScreen value is between 0 and screenCount-1, inclusive
- (values outside this range will result in a Value error).
-
- The displayname is the name used to open the display, either from
- the Xdmx command-line or from the configuration file.
-
- The logicalScreen value is the value of the screen that that Xdmx
- server exports to clients. When Xinerama is in use, this value is
- typically 0 for all values of physicalScreen. If Xinerama is in
- use, the rootWindowXOrigin and rootWindowYOrigin values specify
- where the physical screen is positioned in the global Xinerama
- coordinate system. Otherwise, these values are set to 0.
-
- The screenWindow values comprise a geometry specification (see
- X(7x)) for the location of the DMX screen on the back-end screen.
- The coordinant system of the back-end display is used.
-
- The first four rootWindow values comprise a geometry specification
- (see X(7x)) for the location of the root window on the screen
- window. The coordinant system of the screen window is used. In
- most cases, the root window will have the same geometry as the DMX
- screen window, and will occupy the same area of the back-end
- display. (This would not be the case, for example, if automatic
- projector alignment is used.)
-
-
-
- DMXChangeScreensAttributes
- screenCount: CARD32
- maskCount: CARD32
- screens: LISTofCARD32
- valueMasks: LISTofCARD32
- valueList: LISTofVALUES
- ==>
- status: CARD32
- errorScreen: CARD32
-
- Errors: Length, Alloc
-
- This request was first supported in version 2.0 of this protocol.
- (A singular version of this request with the ability to change some
- RootWindow attributes was supported in version 1.3 of this protocol,
- has been deprecated, and will return BadImplementation.)
-
- This request changes the geometries and positions of the DMX screen
- and DMX root windows on the back-end X servers.
-
- The valueMask and valueList specify which attributes are to be
- changed. The possible values are:
-
- Attribute Type
-
- ScreenWindowWidth CARD16
- ScreenWindowHeight CARD16
- ScreenWindowXoffset INT16
- ScreenWindowYoffset INT16
- RootWindowWidth CARD16
- RootWindowHeight CARD16
- RootWindowXoffset INT16
- RootWindowYoffset INT16
- RootWindowXorigin INT16
- RootWindowYorigin INT16
-
- The attribute values have the same meaning as do the corresponding
- values for DMXGetScreenAttributes.
-
- Non-fatal errors will be returned in status (0 otherwise):
- DmxBadXinerama: Xinerama is not active
- DmxBadValue: The resulting position is not allowed
- (e.g., one corner is outside the bounding box)
- On error, errorScreen will contain the number of the screen that
- caused the first error.
-
-
-
- DMXAddScreen
- displayName: STRING8
- physicalScreen: CARD32
- valueMask: CARD32
- valueList: LISTofVALUES
- ==>
- status: CARD32
- physicalScreen: CARD32
-
- Errors: Length, Alloc, Value
-
- This request was first supported in version 2.2 of this protocol.
-
- This request re-attaches the back-end physicalScreen to the Xdmx
- server. Only back-end screens that have been previously detached
- with DMXRemoveScreen may be added. The name of the back-end display
- is given in displayName, and this will replace the name of the
- back-end screen that was detached. Both the displayName and
- physicalScreen must be correct for this request to work.
-
- The valueMask and valueList specify the attributes to be used. The
- possible values are:
-
- Attribute Type
-
- ScreenWindowWidth CARD16
- ScreenWindowHeight CARD16
- ScreenWindowXoffset INT16
- ScreenWindowYoffset INT16
- RootWindowWidth CARD16
- RootWindowHeight CARD16
- RootWindowXoffset INT16
- RootWindowYoffset INT16
- RootWindowXorigin INT16
- RootWindowYorigin INT16
-
- The attribute values have the same meaning as do the corresponding
- values for DMXGetScreenAttributes.
-
- On success, status will be 0 and physicalScreen will contain the new
- screen number. On failure, status will be non-zero. The status
- will be 1 if any of the following occured:
- * the -addremovescreens command-line option was not specified on
- the Xdmx command line
- * the value of physicalScreen is out of range
- * physicalScreen has not been detached (with DMXRemoveScreen)
- * displayName cannot be opened
- * the visuals of displayname do not match the visuals that Xdmx
- is using
- * the screen data for displayName does not match the data for the
- previously removed display
- The status will be DmxBadValue if the attribute values are out of
- range.
-
-
-
- DMXRemoveScreen
- physicalScreen: CARD32
- ==>
- status: CARD32
-
- Errors: None
-
- This request was first supported in version 2.2 of this protocol.
-
- This request detaches the physicalScreen screen.
-
- On success, status will be 0. On failure, the status will 1 if any
- of the following occur:
- * the -addremovescreens command-line option was not specified on
- the Xdmx command line
- * the value of physicalScreen is out of range
- * the back-end screen has already been detached.
-
-
-
- DMXGetWindowAttributes
- window: CARD32
- ==>
- screenCount: CARD32
- screens: LISTofCARD32
- windows: LISTofCARD32
- pos: LISTofRECTANGLE
- vis: LISTofRECTANGLE
-
- Errors: Window, Alloc
-
- This request computes the return values incorrectly for version 1.0
- of this protocol. Version 1.1 of this protocol conforms to this
- description. In version 2.0, the name of this request was changed
- from DMXGetWindowInformation. However, since the request itself did
- not change, no changes to the underlying protocol were made.
-
- Given a window ID on the Xdmx server, this request returns data
- about how the window is represented on the back-end X servers. For
- each back-end X server that displays a portion of the window, the
- following information is returned:
- 1) the number of the physical screen containing that portion
- (which can be used with the DMXGetScreenAttributes request
- to obtain more information about the screen),
- 2) the window ID on the back-end X server of the window
- containing that portion,
- 3) the position and dimensions of the window on the back-end, in
- screen coordinates, and
- 4) the visible area of the window on the back-end, in
- window-relative coordinates (all zeros for windows that are
- not visible).
- Note that DMX allows multiple back-end windows to overlap in their
- view of the DMX logical window. Further, a logical window does not
- have to be completely covered by back-end windows -- there may be
- gaps.
-
- As an example, consider a 500x500 window that spans the top two
- 1024x768 back-end displays (A and B) of a 2048x1536 DMX display
- composed of 4 1024x768 back-end displays arranged in a cube:
- A B
- C D
-
- In this case, the DMXGetWindowAttributes call would return the
- following information for the 500x500 window:
-
- display A: 500x500 window at 1024-250,0 (relative to back end)
- with 250x500 visible at 0,0 (relative to window origin)
-
- display B: 500x500 window at -250,0 (relative to back end)
- with 250x500 visible at 250,0 (relative to window origin)
-
- display C: 500x500 window at 1024-250,-768 with 0x0 visible at 0,0
-
- display D: 500x500 window at -250,-768 with 0x0 visible at 0,0
-
- Note that if the specified window has not yet been mapped when
- DMXGetWindowAttributes is called, then a subsequent XMapWindow call
- might be buffered in xlib while requests directly to the back-end X
- servers are processed. This race condition can be solved by calling
- DMXSync before talking directly to the back-end X servers.
-
-
-
- DMXGetDesktopAttributes
- ==>
- width: INT16
- height: INT16
- shiftX: INT16
- shiftY: INT16
-
- Errors: None
-
- This request was first supported in version 2.0 of this protocol.
-
- This request returns the size of the bounding box of the whole
- screen in width and height. The shiftX and shiftY values will
- always be 0. The global bounding box is computed whether or not
- Xinerama is active, and may be larger than the Xinerama screen size
- because of information in the configuration file.
-
-
-
- DMXChangeDesktopAttributes
- valueMask: BITMASK
- valueList: LISTofVALUE
- ==>
- status: CARD32
-
- Errors: Length, Value
-
- This request was first supported in version 2.0 of this protocol.
-
- This request resizes the bounding box of the whole screen when using
- the Xinerama extension. Otherwise, it has no effect on the screen
- layout. The valueMask and valueList specify which attributes are to
- be changed. The possible values are:
-
- Attriubute Type
-
- Width INT16
- Height INT16
- ShiftX INT16
- ShiftY INT16
-
- Width and Height specify the new width and height for the bounding
- box. ShiftX and ShiftY specify where the Xinerama origin will be
- placed with respect to the origin of the new bounding box. This
- allows the left and upper edges of the bounding box to be changed
- without changing the visual position of the windows on the desktop.
- If Width or Height is not specified, the current values will be
- used. If ShiftX or ShiftY is not specified, 0 will be used.
-
- All coordinants are in the global DMX coordinant system. If
- Xinerama is not active, this request is not useful.
-
- Non-fatal errors will be returned in status (0 otherwise):
- DmxBadXinerama: Xinerama is not active
- DmxBadValue: The size of the bounding box is too large
-
-
-
- DMXGetInputCount
- ==>
- inputCount: CARD32
-
- This request was first supported in version 1.1 of this protocol.
-
- This request returns the number of input devices connected to the
- Xdmx server. This number is the same as that returned by
- XListInputDevices, but is available even when the XInput extension
- is not supported.
-
-
-
- DMXGetInputAttributes
- deviceId: CARD32
- ==>
- inputType: CARD32
- physicalScreen: CARD32
- physicalId: CARD32
- isCore: BOOL
- sendsCore: BOOL
- detached: BOOL
- name: STRING8
-
- Errors: Value
-
- This request was first supported in version 1.1 of this protocol.
- In version 2.0, the name of this request was changed from
- DMXGetInputInformation. However, since the request itself did not
- change, no changes to the underlying protocol were made. In version
- 2.2, the name of detached was changed from reservation. There was
- no change in underlying protocol.
-
- This request returns information about the specified input device
- that cannot be obtained from the XListInputDeivices call. The
- deviceId is the same as that used by the XListInputDevices call, and
- must be in the range 0 to inputCount-1, inclusive (values outside
- this range will result in a Value error).
-
- The value of inputType will always be valid, and will be one of the
- following values:
- 0 for local (and dummy) devices,
- 1 for console devices, and
- 2 for back-end devices.
-
- For local devices, all other fields returned, except isCore and
- sendsCore, are invalid.
-
- For console devices, the physicalScreen and physicalID will be
- invalid, and the name will return the name of the X server on which
- the console window is displayed.
-
- For back-end devices, the physicalScreen will identify the back-end
- display and can be used as an argument to DMXGetScreenAttributes to
- obtain more information; the physicalId will be the XInput device id
- on the back-end X server; and the name will be invalid (since it
- does not provide any additional information that cannot be obtained
- with DMXGetScreenAttributes).
-
- If isCore is True, then this device is active as a true core input
- device and will send core events. If sendsCore is True, then this
- device is an XInput extension device, but sends core events instead
- of extension events. Note that this behavior is different from that
- of XFree86 or Xorg, where XInput extension devices may send both
- extension events and core events.
-
- If detached is True, then this device has been detached and is no
- longer producing input events. The device may be reattached using
- DMXAddInput.
-
-
-
- DMXAddInput
- displayName: STRING8
- valueMask: CARD32
- valueList: LISTofVALUES
- ==>
- status: CARD32
- physicalId: CARD32
-
- Errors: Value, Access
-
- This request was first supported in version 2.2 of this protocol.
-
- The valueMask and valueList specify the attributes to be used. The
- possible values are:
-
- Attribute Type
-
- InputType CARD32
- InputPhysicalScreen CARD32
- InputSendsCore BOOL
-
- This request attaches an input device to the Xdmx server. The value
- of inputType will be one:
- 1 for console devices, and
- 2 for back-end devices.
- Other values of InputType will return a BadValue error. Local
- devices (inputType=0 in DMXGetInputAttributes) cannot be attached or
- removed. For console devices, displayName will store the name of
- the display to be used.
-
- For back-end devices, InputPhysicalScreen will specify the screen
- number. BadValue will be returned if the screen number is out of
- range. BadAccess will be returned if the input has already been
- attached or if the backend screen is currently detached.
-
- If InputSendsCore is True, the new device will be added as a true
- core device.
-
- If a device was removed with DMXRemoveInput an attempt will be made
- to reconnect the previous devices (InputSendsCore is ignored in this
- case).
-
-
-
- DMXRemoveInput
- physicalId: CARD32
- ==>
- status: CARD32
-
- Errors: Value, Access
-
- This request was first supported in version 2.2 of this protocol.
-
- This request detaches the input device with physicalId, and all
- associated inputs (e.g., if the physicalId is a backend mouse, and a
- keyboard is also attached to the backend, then both devices will be
- detached). If the physicalId is outside the valid range (0 to one
- less than the value returned by DMXInputCount), BadValue is
- returned. If the physicalId has already been detached, BadAccess is
- returned. The status is always 0.
