XSetWMNormalHints()XSetWMNormalHints()NameXSetWMNormalHints – 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.
DescriptionXSetWMNormalHints() sets the size hints in the XA_WM_NORMAL_HINTS prop‐
erty on the specified window. The property is stored with a type of
WM_SIZE_HINTS and a format of 32. XSetWMNormalHints() supersedes XSet‐
NormalHints(). This property can also be set with XSetWMProperties().
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.

cation.
