Method Detail

getLibrary

public static SharedLibrary getLibrary()

Returns the X11 SharedLibrary.

nXOpenDisplay

public static long nXOpenDisplay(long display_name)

Unsafe version of: XOpenDisplay(java.nio.ByteBuffer)

XOpenDisplay

public static long XOpenDisplay(@Nullable
                                java.nio.ByteBuffer display_name)

public static long XOpenDisplay(@Nullable
                                java.lang.CharSequence display_name)

Returns a Display structure that serves as the connection to the X server and that contains all the information about that X server. XOpenDisplay connects your application to the X server through TCP or DECnet communications protocols, or through some local inter-process communication protocol. If the hostname is a host machine name and a single colon (:) separates the hostname and display number, XOpenDisplay connects using TCP streams. If the hostname is not specified, Xlib uses whatever it believes is the fastest transport. If the hostname is a host machine name and a double colon (::) separates the hostname and display number, XOpenDisplay connects using DECnet. A single X server can support any or all of these transport mechanisms simultaneously. A particular Xlib implementation can support many more of these transport mechanisms.

Parameters:

display_name - the hardware display name, which determines the display and communications domain to be used. On a POSIX-conformant system, if the display_name is NULL, it defaults to the value of the DISPLAY environment variable.

XCloseDisplay

public static void XCloseDisplay(long display)

Closes the connection to the X server for the display specified in the Display structure and destroys all windows, resource IDs (Window, Font, Pixmap, Colormap, Cursor, and GContext), or other resources that the client has created on this display, unless the close-down mode of the resource has been changed (see XSetCloseDownMode()). Therefore, these windows, resource IDs, and other resources should never be referenced again or an error will be generated. Before exiting, you should call XCloseDisplay() explicitly so that any pending errors are reported as XCloseDisplay() performs a final XSync() operation.

Parameters:

display - the connection to the X server

XDefaultScreen

public static int XDefaultScreen(long display)

Returns a pointer to the default screen.

Parameters:

display - the connection to the X server

XRootWindow

public static long XRootWindow(long display,
                               int screen_number)

Returns the root window of the specified screen.

Parameters:

display - the connection to the X server

screen_number - the appropriate screen number on the host server

nXCreateColormap

public static long nXCreateColormap(long display,
                                    long w,
                                    long visual,
                                    int alloc)

Unsafe version of: XCreateColormap(long, long, org.lwjgl.system.linux.Visual, int)

XCreateColormap

public static long XCreateColormap(long display,
                                   long w,
                                   Visual visual,
                                   int alloc)

Creates a colormap of the specified visual type for the screen on which the specified window resides and returns the colormap ID associated with it. Note that the specified window is only used to determine the screen.

Parameters:

display - the connection to the X server

w - the window

visual - a visual type supported on the screen. If the visual type is not one supported by the screen, a BadMatch error results.

alloc - the colormap entries to be allocated. You can pass AllocNone or AllocAll.

XFreeColormap

public static int XFreeColormap(long display,
                                long colormap)

Deletes the association between the colormap resource ID and the colormap and frees the colormap storage. However, this function has no effect on the default colormap for a screen. If the specified colormap is an installed map for a screen, it is uninstalled. If the specified colormap is defined as the colormap for a window, XFreeColormap() changes the colormap associated with the window to None and generates a ColormapNotify event. X does not define the colors displayed for a window with a colormap of None.

Parameters:

display - the connection to the X server

colormap - the colormap to destroy

nXCreateWindow

public static long nXCreateWindow(long display,
                                  long parent,
                                  int x,
                                  int y,

                                  int border_width,
                                  int depth,
                                  int windowClass,
                                  long visual,
                                  long valuemask,
                                  long attributes)

Unsafe version of: XCreateWindow(long, long, int, int, int, int, int, int, int, org.lwjgl.system.linux.Visual, long, org.lwjgl.system.linux.XSetWindowAttributes)

XCreateWindow

public static long XCreateWindow(long display,
                                 long parent,
                                 int x,
                                 int y,
                                 int width,
                                 int height,
                                 int border_width,
                                 int depth,
                                 int windowClass,
                                 Visual visual,
                                 long valuemask,
                                 XSetWindowAttributes attributes)

Creates an unmapped subwindow for a specified parent window, returns the window ID of the created window, and causes the X server to generate a CreateNotify event. The created window is placed on top in the stacking order with respect to siblings.

The coordinate system has the X axis horizontal and the Y axis vertical with the origin [0, 0] at the upper-left corner. Coordinates are integral, in terms of pixels, and coincide with pixel centers. Each window and pixmap has its own coordinate system. For a window, the origin is inside the border at the inside, upper-left corner.

The x and y coordinates are the top-left outside corner of the window's borders and are relative to the inside of the parent window's borders.

The width and height are the created window's inside dimensions and do not include the created window's borders.

Parameters:

display - the connection to the X server

parent - the parent window

x - the window x-coordinate

y - the window y-coordinate

width - the window width

height - the window height

border_width - the border width

depth - the window's depth. A depth of CopyFromParent means the depth is taken from the parent.

windowClass - the created window's class. One of:

InputOutput

InputOnly

CopyFromParent

visual - the visual type. A visual of CopyFromParent means the visual type is taken from the parent.

valuemask - which window attributes are defined in the attributes argument. This mask is the bitwise inclusive OR of the valid attribute mask bits. If valuemask is zero, the attributes are ignored and are not referenced.

attributes - the structure from which the values (as specified by the value mask) are to be taken

XDestroyWindow

public static int XDestroyWindow(long display,
                                 long w)

Destroys the specified window as well as all of its subwindows and causes the X server to generate a DestroyNotify event for each window. The window should never be referenced again. If the window specified by the w argument is mapped, it is unmapped automatically. The ordering of the DestroyNotify events is such that for any given window being destroyed, DestroyNotify is generated on any inferiors of the window before being generated on the window itself. The ordering among siblings and across subhierarchies is not otherwise constrained. If the window you specified is a root window, no windows are destroyed. Destroying a mapped window will generate Expose events on other windows that were obscured by the window being destroyed.

Parameters:

display - the connection to the X server

w - the window

nXFree

XSendEvent

public static int XSendEvent(long display,
                             long w,
                             boolean propagate,
                             long event_mask,
                             XEvent event_send)

The XSendEvent function identifies the destination window, determines which clients should receive the specified events, and ignores any active grabs. This function requires you to pass an event mask. This function uses the w argument to identify the destination window as follows:

• If w is PointerWindow, the destination window is the window that contains the pointer.
• If w is InputFocus and if the focus window contains the pointer, the destination window is the window that contains the pointer; otherwise, the destination window is the focus window.

To determine which clients should receive the specified events, XSendEvent uses the propagate argument as follows:

• If event_mask is the empty set, the event is sent to the client that created the destination window. If that client no longer exists, no event is sent.
• If propagate is False, the event is sent to every client selecting on destination any of the event types in the event_mask argument.
• If propagate is True and no clients have selected on destination any of the event types in event-mask, the destination is replaced with the closest ancestor of destination for which some client has selected a type in event-mask and for which no intervening window has that type in its do-not-propagate-mask. If no such window exists or if the window is an ancestor of the focus window and InputFocus was originally specified as the destination, the event is not sent to any clients. Otherwise, the event is reported to every client selecting on the final destination any of the types specified in event_mask.

The event in the XEvent structure must be one of the core events or one of the events defined by an extension (or a BadValue error results) so that the X server can correctly byte-swap the contents as necessary. The contents of the event are otherwise unaltered and unchecked by the X server except to force send_event to True in the forwarded event and to set the serial number in the event correctly; therefore these fields and the display field are ignored by XSendEvent.

XSendEvent returns zero if the conversion to wire protocol format failed and returns nonzero otherwise. XSendEvent can generate BadValue and BadWindow errors.

The server may retain the recent history of the pointer motion and do so to a finer granularity than is reported by MotionNotify events. The XGetMotionEvents(long, long, long, long) function makes this history available.

Parameters:

display - the connection to the X server

w - specifies the window the event is to be sent to

propagate - specifies a Boolean value

event_mask - specifies the event mask

event_send - specifies the event that is to be sent

XGetMotionEvents

@Nullable
public static XTimeCoord.Buffer XGetMotionEvents(long display,
                                                 long w,
                                                 long start,
                                                 long stop)

The XGetMotionEvents function returns all events in the motion history buffer that fall between the specified start and stop times, inclusive, and that have coordinates that lie within the specified window (including its borders) at its present placement.

If the server does not support motion history, if the start time is later than the stop time, or if the start time is in the future, no events are returned; XGetMotionEvents returns NULL. If the stop time is in the future, it is equivalent to specifying CurrentTime. XGetMotionEvents can generate a BadWindow error.

Parameters:

display - the connection to the X server

                                            CLongBuffer child_return)

Translates window coordinates.

If XTranslateCoordinates returns True, it takes the src_x and src_y coordinates relative to the source window's origin and returns these coordinates to dest_x_return and dest_y_return relative to the destination window's origin. If XTranslateCoordinates returns False, src_w and dest_w are on different screens, and dest_x_return and dest_y_return are zero. If the coordinates are contained in a mapped child of dest_w, that child is returned to child_return. Otherwise, child_return is set to None.

XTranslateCoordinates can generate a BadWindow error.

Parameters:

display - the connection to the X server

src_w - specifies the source window

dest_w - specifies the destination window

src_x - specifies the x coordinate within the source window

src_y - specifies the x coordinate within the source window

dest_x_return - returns the x coordinate within the destination window

dest_y_return - returns the y coordinate within the destination window

child_return - returns the child if the coordinates are contained in a mapped child of the destination window
