XConfigureWindow(3) XLIB FUNCTIONS XConfigureWindow(3)

NAME XConfigureWindow, XMoveWindow, XResizeWindow, XMoveResizeWindow,

XSetWindowBorderWidth, XWindowChanges - configure windows and window changes structure SYNTAX int XConfigureWindow(Display *display, Window w, unsigned valuemask, XWindowChanges *changes); int XMoveWindow(Display *display, Window w, int x, y); int XResizeWindow(Display *display, Window w, unsigned width, unsigned height); int XMoveResizeWindow(Display *display, Window w, int x, int y, unsigned width, unsigned height); int XSetWindowBorderWidth(Display *display, Window w, unsigned width); ARGUMENTS display Specifies the connection to the X server. valuemask Specifies which values are to be set using information in the values structure. This mask is the bitwise inclusive OR of the valid configure window values bits. values Specifies the XWindowChanges structure. w Specifies the window to be reconfigured, moved, or resized.. width Specifies the width of the window border. width height Specify the width and height, which are the interior dimen‐ sions of the window. x y Specify the x and y coordinates, which define the new loca‐

tion of the top-left pixel of the window's border or the win‐ dow itself if it has no border or define the new position of the window relative to its parent. DESCRIPTION The XConfigureWindow function uses the values specified in the XWin‐ dowChanges structure to reconfigure a window's size, position, border, and stacking order. Values not specified are taken from the existing geometry of the window. If a sibling is specified without a stackmode or if the window is not actually a sibling, a BadMatch error results. Note that the computa‐ tions for BottomIf, TopIf, and Opposite are performed with respect to the window's final geometry (as controlled by the other arguments passed to XConfigureWindow), not its initial geometry. Any backing store contents of the window, its inferiors, and other newly visible windows are either discarded or changed to reflect the current screen contents (depending on the implementation). XConfigureWindow can generate BadMatch, BadValue, and BadWindow errors. The XMoveWindow function moves the specified window to the specified x and y coordinates, but it does not change the window's size, raise the window, or change the mapping state of the window. Moving a mapped window may or may not lose the window's contents depending on if the window is obscured by nonchildren and if no backing store exists. If the contents of the window are lost, the X server generates Expose events. Moving a mapped window generates Expose events on any formerly obscured windows.

If the override-redirect flag of the window is False and some other client has selected SubstructureRedirectMask on the parent, the X server generates a ConfigureRequest event, and no further processing is performed. Otherwise, the window is moved. XMoveWindow can generate a BadWindow error. The XResizeWindow function changes the inside dimensions of the speci‐ fied window, not including its borders. This function does not change

the window's upper-left coordinate or the origin and does not restack the window. Changing the size of a mapped window may lose its contents and generate Expose events. If a mapped window is made smaller, chang‐ ing its size generates Expose events on windows that the mapped window formerly obscured.

If the override-redirect flag of the window is False and some other client has selected SubstructureRedirectMask on the parent, the X server generates a ConfigureRequest event, and no further processing is performed. If either width or height is zero, a BadValue error results. XResizeWindow can generate BadValue and BadWindow errors. The XMoveResizeWindow function changes the size and location of the specified window without raising it. Moving and resizing a mapped win‐ dow may generate an Expose event on the window. Depending on the new size and location parameters, moving and resizing a window may generate Expose events on windows that the window formerly obscured.

If the override-redirect flag of the window is False and some other client has selected SubstructureRedirectMask on the parent, the X server generates a ConfigureRequest event, and no further processing is performed. Otherwise, the window size and location are changed. XMoveResizeWindow can generate BadValue and BadWindow errors. The XSetWindowBorderWidth function sets the specified window's border width to the specified width. XSetWindowBorderWidth can generate a BadWindow error. STRUCTURES The XWindowChanges structure contains: /* Configure window value mask bits */

#define CWX (1<<0)

#define CWY (1<<1)

#define CWWidth (1<<2)

#define CWHeight (1<<3)

#define CWBorderWidth (1<<4)

#define CWSibling (1<<5)

#define CWStackMode (1<<6) /* Values */ typedef struct { int x, y; int width, height; int borderwidth; Window sibling; int stackmode; } XWindowChanges; The x and y members are used to set the window's x and y coordinates, which are relative to the parent's origin and indicate the position of

the upper-left outer corner of the window. The width and height mem‐ bers are used to set the inside size of the window, not including the border, and must be nonzero, or a BadValue error results. Attempts to configure a root window have no effect. The borderwidth member is used to set the width of the border in pix‐

els. Note that setting just the border width leaves the outer-left corner of the window in a fixed position but moves the absolute posi‐

tion of the window's origin. If you attempt to set the border-width attribute of an InputOnly window nonzero, a BadMatch error results. The sibling member is used to set the sibling window for stacking oper‐ ations. The stackmode member is used to set how the window is to be restacked and can be set to Above, Below, TopIf, BottomIf, or Opposite. DIAGNOSTICS BadMatch An InputOnly window is used as a Drawable. 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. 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.
