GtSizeHints(3X) — DeltaWindows 1.3.3 Release 4 Version 4.3

NAME

XGetSizeHints — read any property of type XA_WM_SIZE_HINTS.

SYNOPSIS

Status XGetSizeHints(display, w, hints_return, property) Display ∗display; Window w; XSizeHints ∗hints_return; Atom property;

ARGUMENTS

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

wSpecifies the ID of the window for which size hints will be returned.

hints_return
Returns the size hints structure.

propertySpecifies a property atom of type XA_WM_SIZE_HINTS. May be XA_WM_NORMAL_HINTS, XA_WM_ZOOM_HINTS (in Release 3), or a property defined by an application.

RETURNS

Zero on failure, non-zero on success.

DESCRIPTION

XGetSizeHints() has been superseded by XGetWMSizeHints() as of Release 4, because the interclient communication conventions are now standard.

XGetSizeHints() returns the XSizeHints structure for the named property and the specified window. XGetSizeHints() is used by XGetNormalHints() and XGetZoomHints(), and can be used to retrieve the value of any property of type XA_WM_SIZE_HINTS; thus, it is useful if other properties of that type get defined. This function is used almost exclusively by window managers.

XGetSizeHints() returns a non-zero Status if a size hint was defined, and zero otherwise.

For more information on using hints, see Volume One, Chapter 10, Interclient Communication.
