XSetNormalHints()XSetNormalHints()NameXSetNormalHints – set the size hints property of a window in normal
state (not zoomed or iconified).
Synopsis
void XSetNormalHints(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 ID.
hints Specifies a pointer to the sizing hints for the window in its
normal state.
DescriptionXSetNormalHints() has been superseded by XSetWMNormalHints() as of
Release 4.
XSetNormalHints() sets the XA_WM_NORMAL_HINTS property for the speci‐
fied window. Applications use XSetNormalHints() to inform the window
manager of the size or position desirable for that window. In addi‐
tion, an application wanting to move or resize itself should call XSet‐
NormalHints() specifying its new desired location and size, in addition
to making direct X calls to move or resize. This is because some win‐
dow managers may redirect window configuration requests, but ignore the
resulting events and pay attention to property changes instead.
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.
For more information on using hints, see Volume One, Chapter 12, Inter‐
client Communication.
