XSetZoomHin(3x) — HP-UX ANSI C A.09.00

NAME

XSetZoomHints − set the size hints property of a zoomed window.

Synopsis

XSetZoomHints(display, w, zhints)
Display *display;
Window w;
XSizeHints *zhints;

Arguments

displaySpecifies a connection to an X server; returned from XOpenDisplay().

wSpecifies the ID of the window for which zoom hints are to be set.

zhintsSpecifies a pointer to the zoom hints.

Description

XSetZoomHints() is no longer used as of Release 3. XSetZoomHints() sets the XA_WM_ZOOM_HINTS property for an application’s top-level window in its zoomed state. Many window managers think of windows in three states: iconified, normal, or zoomed, corresponding to small, medium, and large. Applications use XSetZoomHints() to inform the window manager of the size or position desirable for the zoomed window. In addition, an application wanting to move or resize its zoomed window should call XSetZoomHints() specifying its new desired location and size, in addition to making direct X calls to move or resize. This is because some window 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 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 10, Interclient Communication.
