XCreateWindow(3)		XLIB FUNCTIONS		      XCreateWindow(3)

NAME
       XCreateWindow, XCreateSimpleWindow, XSetWindowAttributes - create win‐
       dows and window attributes structure

SYNTAX
       Window XCreateWindow(Display *display, Window parent, int x, int y,
	      unsigned int width, unsigned int height, unsigned int bor‐
	      der_width, int depth, unsigned int class, Visual *visual,
	      unsigned long valuemask, XSetWindowAttributes *attributes);

       Window XCreateSimpleWindow(Display *display, Window parent, int x, int
	      y, unsigned int width, unsigned int height, unsigned int bor‐
	      der_width, unsigned long border, unsigned long background);

ARGUMENTS
       attributes
		 Specifies the structure from which the values (as specified
		 by the value mask) are to be taken.  The value mask should
		 have the appropriate bits set to indicate which attributes
		 have been set in the structure.

       background
		 Specifies the background pixel value of the window.

       border	 Specifies the border pixel value of the window.

       border_width
		 Specifies the width of the created window's border in pixels.

       class	 Specifies the created window's class.	You can pass InputOut‐
		 put, InputOnly, or CopyFromParent.  A class of CopyFromParent
		 means the class is taken from the parent.

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

       display	 Specifies the connection to the X server.

       parent	 Specifies the parent window.

       valuemask Specifies 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.

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

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

       x
       y	 Specify the x and y coordinates, which are the top-left out‐
		 side corner of the window's borders and are relative to the
		 inside of the parent window's borders.

DESCRIPTION
       The XCreateWindow function creates an unmapped subwindow for a speci‐
       fied parent window, returns the window ID of the created window, and
       causes the X server to generate a CreateNotify event.  The created win‐
       dow 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 inte‐
       gral, 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 border_width for an InputOnly window must be zero, or a BadMatch
       error results.  For class InputOutput, the visual type and depth must
       be a combination supported for the screen, or a BadMatch error results.
       The depth need not be the same as the parent, but the parent must not
       be a window of class InputOnly, or a BadMatch error results.  For an
       InputOnly window, the depth must be zero, and the visual must be one
       supported by the screen.	 If either condition is not met, a BadMatch
       error results.  The parent window, however, may have any depth and
       class.  If you specify any invalid window attribute for a window, a
       BadMatch error results.

       The created window is not yet displayed (mapped) on the user's display.
       To display the window, call XMapWindow.	The new window initially uses
       the same cursor as its parent.  A new cursor can be defined for the new
       window by calling XDefineCursor.	 The window will not be visible on the
       screen unless it and all of its ancestors are mapped and it is not
       obscured by any of its ancestors.

       XCreateWindow can generate BadAlloc BadColor, BadCursor, BadMatch, Bad‐
       Pixmap, BadValue, and BadWindow errors.

       The XCreateSimpleWindow function creates an unmapped InputOutput sub‐
       window for a specified parent window, returns the window ID of the cre‐
       ated 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.  Any part of the window that extends outside its parent
       window is clipped.  The border_width for an InputOnly window must be
       zero, or a BadMatch error results.  XCreateSimpleWindow inherits its
       depth, class, and visual from its parent.  All other window attributes,
       except background and border, have their default values.

       XCreateSimpleWindow can generate BadAlloc, BadMatch, BadValue, and Bad‐
       Window errors.

STRUCTURES
       The XSetWindowAttributes structure contains:

       /* Window attribute value mask bits */

       #define	 CWBackPixmap		     (1L<<0)
       #define	 CWBackPixel		     (1L<<1)
       #define	 CWBorderPixmap		     (1L<<2)
       #define	 CWBorderPixel		     (1L<<3)

       #define	 CWCursor		     (1L<<14)
       /* Values */

       typedef struct {
	    Pixmap background_pixmap;/* background, None, or ParentRelative */
	    unsigned long background_pixel;/* background pixel */
	    Pixmap border_pixmap;    /* border of the window or CopyFromParent */
	    unsigned long border_pixel;/* border pixel value */
	    int bit_gravity;	     /* one of bit gravity values */
	    int win_gravity;	     /* one of the window gravity values */
	    int backing_store;	     /* NotUseful, WhenMapped, Always */
	    unsigned long backing_planes;/* planes to be preserved if possible */
	    unsigned long backing_pixel;/* value to use in restoring planes */
	    Bool save_under;	     /* should bits under be saved? (popups) */
	    long event_mask;	     /* set of events that should be saved */
	    long do_not_propagate_mask;/* set of events that should not propagate */
	    Bool override_redirect;  /* boolean value for override_redirect */
	    Colormap colormap;	     /* color map to be associated with window */
	    Cursor cursor;	     /* cursor to be displayed (or None) */
       } XSetWindowAttributes;

       C Language X Interface.

DIAGNOSTICS
       BadAlloc	 The server failed to allocate the requested resource or
		 server memory.

       BadColor	 A value for a Colormap argument does not name a defined Col‐
		 ormap.

       BadCursor A value for a Cursor argument does not name a defined Cursor.

       BadMatch	 The values do not exist for an InputOnly window.

       BadMatch	 Some argument or pair of arguments has the correct type and
		 range but fails to match in some other way required by the
		 request.

       BadPixmap A value for a Pixmap argument does not name a defined Pixmap.

       BadValue	 Some numeric value falls outside the range of values accepted
		 by the request.  Unless a specific range is specified for an
		 argument, the full range defined by the argument's type is
		 accepted.  Any argument defined as a set of alternatives can
		 generate this error.

       BadWindow A value for a Window argument does not name a defined Window.
