XSetWMSizeHints()XSetWMSizeHints()NameXSetWMSizeHints – set a window's XA_WM_SIZE_HINTS property.
Synopsis
void XSetWMSizeHints(display, w, hints, property)
Display *display;
Window w;
XSizeHints *hints;
Atom property;
Arguments
display Specifies a connection to an X server; returned from
XOpenDisplay().
w Specifies the window.
hints Specifies the XSizeHints structure to be used.
property Specifies the property name.
Availability
Release 4 and later.
DescriptionXSetWMSizeHints() sets the size hints for the specified property on the
named window. The property is stored with a type of XA_WM_SIZE_HINTS
and a format of 32. To set a window's normal size hints, you can use
the XSetWMNormalHints() function instead. XSetWMSizeHints() supersedes
XSetSizeHints().
This routine is useful if new properties of type XA_WM_SIZE_HINTS are
defined.
The flags member of XSizeHints must be set to the OR of the symbols
representing each member to be set.

cation.
