winope(3G)winope(3G)NAMEwinope - creates a graphics window
FORTRAN 77 SPECIFICATION
integer*4 function winope(name, length)
character*(*) name
integer*4 length
PARAMETERS
name expects the window title that is displayed on the left hand side
of the title bar for the window. If you do not want a title,
pass a zero-length string.
length expects the length of the string in name.
FUNCTION RETURN VALUE
The returned value for this function is the graphics server and window
identifier for the window just created. Use this value to identify the
graphics window to other windowing functions. Only the lower 16 bits are
significant, since a graphics window identifier is the value portion of a
REDRAW event queue entry. If no additional windows are available, this
function returns -1.
DESCRIPTIONwinope creates a graphics window as defined by the current values of the
window constraints on the currently selected display. This new window
becomes the current window. If a call to foregr did not precede the
winope call, it forks and runs the calling process in the background.
The display on which the window is opened is determined by the currently
selected host, server, and screen. The host defaults to the local client
machine. You may change the host by calling dglope beforehand, or by
calling winset with the identifier of an open window on another host. If
neither of these calls precedes, the value of the environment variables
DISPLAY, DGLSERVER, and REMOTEHOST are checked in that order. The
current server defaults to 0. This too may be changed by a preceding
winset; otherwise it may set by the environment variables above. The
current screen defaults to 0. You can change it using the routine
scrnse.
Except for size and location, the graphics host maintains default values
for the constraints on a window. You can change these default window
constraints if you call the routines minsiz, maxsiz, keepas, prefsi,
prefpo, stepun, fudge, iconsi, nobord, noport, imakeb, and foregr before
you call winope. If a window's size and location (or both) are left
unconstrained, the system allows the user to place and size the window.
winope sets the graphics state of the new window (this includes window
constraints) to its default values; there are listed in the table below.
It also queues the pseudo devices INPTCH and REDRAW.

Notes
o Font 0 is a Helvetica-like font.
o Zmin and Zmax are the minimum and maximum values that you can store
in the z-buffer. These depend on the graphics hardware and are
returned by getgde(GDZMIN) and getgde(GDZMAX).
o On IRIS-4D B and G models, winope also sets lsback(.FALSE.) and
resetl(.TRUE.).

NOTES
This routine is available only in immediate mode.
When creating a window on a screen for which there is no window manage-
ment, (i.e., on a screen for which the getgde inquiry GDSTYP returns
GDSTNW), always preface the winope call with
call prefpo(0, getgde(GDXPMA)-1, 0, getgde(GDYPMA)-1)
This will guarantee compatible behavior should the screen have window
management in the future.
BUGS
On the IRIS-4D GT and GTX models only, a window region which extends
beyond 2048 in the horizontal dimension is wrapped around and mapped to a
corresponding window region starting at 512. The bug is visible only if
the window covers both regions.
