XSetWMNormalHints() XSetWMNormalHints()
Name
XSetWMNormalHints - set a window's XA_WM_NORMAL_HINTS property.
Synopsis
void XSetWMNormalHints(display, w, hints)
Display *display;
Window w;
XSizeHints *hints;
Arguments
display Specifies a connection to an X server; returned from XOpenDisplay().
w Specifies the window.
hints Specifies the size hints for the window in its normal state.
Availability
Release 4 and later.
Description
XSetWMNormalHints() sets the size hints in the XA_WM_NORMAL_HINTS property on the specified window. The property is stored with a type of
WM_SIZE_HINTS and a format of 32. XSetWMNormalHints() supersedes XSetNormalHints(). This property can also be set with XSetWMProper-
ties().
Applications use XSetNormalHints() to inform the window manager of the sizes desirable for that window.
To set size hints, an application must assign values to the appropriate elements in the hints structure, and also set the flags field of
the structure to indicate which members have assigned values and the source of the assignment. These flags are listed in the Structures
section below.

XGetWMNormalHints() XGetWMNormalHints()
Name
XGetWMNormalHints - read a window's XA_WM_NORMAL_HINTS property.
Synopsis
Status XGetWMNormalHints(display, w, hints_return, supplied_return)
Display *display;
Window w;
XSizeHints *hints_return;
long *supplied_return;
Arguments
display Specifies a connection to an X server; returned from XOpenDisplay().
w Specifies the window.
hints_return
Returns the size hints for the window in its normal state.
supplied_return
Returns the hints that were supplied by the user.
Returns
Zero on failure, non-zero on success.
Availability
Release 4 and later.
Description
XGetWMNormalHints() returns the size hints stored in the XA_WM_NORMAL_HINTS property on the specified window. If the property is of type
XA_WM_SIZE_HINTS, of format 32, and is long enough to contain either an old (pre-ICCCM) or new size hints structure, XGetWMNormalHints()
sets the various fields of the XSizeHints structure, sets the supplied_return argument to the list of fields that were supplied by the user
(whether or not they contained defined values) and returns a non-zero status. XGetWMNormalHints() returns a zero status if the application
specified no normal size hints for this window.
XGetWMNormalHints() supersedes XGetNormalHints().
If XGetWMNormalHints() returns successfully and a pre-ICCCM size hints property is read, the supplied_return argument will contain the fol-
lowing bits:
(USPosition USSize PPosition PSize PMinSize PMaxSize PResizeInc PAspect)
If the property is large enough to contain the base size and window gravity fields as well, the supplied argument will also contain the
following bits:
(PBaseSize PWinGravity)
This function is normally used only by a window manager.
