NAME

       xforms -   A GUI Toolkit for X Window Systems

SYNOPSIS

       Forms  Library for X (xforms) is a GUI toolkit and builder for the X Window Systems and runs on all major UNIX platforms as well as OpenVMS
       and OS2.  Forms Library is too complex to be described in the "man" page format.  Ask your system administrator for  the  location  of  the
       HTML, PDF or PostScript document or follow the links on the Forms Library's home page for an online version of the documentation.

DESCRIPTION

       Forms  Library  is  a graphical user interface toolkit based on Xlib for X Window Systems. It comes with a rich set of objects such as but-
       tons, browsers, sliders and menus integrated into an elegant event/object callback execution model that allows fast and	easy  construction
       of  X  applications.  In  addition,  the  library  has support for image read and write, format conversion and simple image processing. The
       library consists of a flexible set of C-routines that can be used in C and C++ programs (As of this writing, perl,  ada95,  pascal,  scheme
       and Fortran bindings to the Forms Library are in beta.)

       The  library  is  efficient  and  portable and runs on all major Unix platforms, including Sun, SGI, HP, DEC Alpha/OSF, IBM RS6000, Convex,
       Cray, Linux, FreeBSD, NetBSD, SCO, Unixware, OpenBSD , BSDi, DecSystem(mips)/Ultrix and others.	Non-unix platforms include OpenVMS,  OS/2,
       and Window/NT.

       Bundled	with the library is also a Form designer, fdesign, which can be used to build interaction forms in a WYSIWYG (what you see is what
       you get) way and to generate the corresponding C (or any of the binding languages) code for you.  50+ demos in source code are  distributed
       with the library.

OPTIONS

       All programs written using the Forms Library recognize the following command line options

       -display host:dpy
	     specifies the server to connect to.

       -bw borderwidth
	     specifies the border width to use for built-in objects.

       -flversion
	     prints the xforms version information.

       -visual visualName
	     requests a visual by name such as TrueColor etc. By default the Forms Library always selects the visual that has the most depth.

       -depth depth
	     requests a specific depth.

       -fldebug level
	     generates	some  info about the state of the XForms.  where level is an integer between 1-5 and controls the amount of information to
	     output. Depending on the options used when the Forms Library was built, a level more than 3 might not be available.

       -sync runs the application in synchronous mode with debug level set to 4.

       -private
	     requests a private colormap for the application.

       -shared
	     requests a shared colormap even if the application needs more colors than available. For those colors that can't be allocated in  the
	     shared colormap, substitutions are made so the closest matching color is used.

       -stdcmap
	     requests a standard colormap.

       -name  newname
	     specifies the application name under which resources are to be obtained, rather than the default executable file name.

NAME

       Tk_GetVisual - translate from string to visual

SYNOPSIS

       #include <tk.h>

       Visual *
       Tk_GetVisual(interp, tkwin, string, depthPtr, colormapPtr)

ARGUMENTS

       Tcl_Interp *interp (in)		     Interpreter to use for error reporting.

       Tk_Window tkwin (in)		     Token for window in which the visual will be used.

       const char *string (in)		     String that identifies the desired visual.  See below for valid formats.

       int *depthPtr (out)		     Depth of returned visual gets stored here.

       Colormap *colormapPtr (out)	     If non-NULL then a suitable colormap for visual is found and its identifier is stored here.
_________________________________________________________________

DESCRIPTION

       Tk_GetVisual  takes a string description of a visual and finds a suitable X Visual for use in tkwin, if there is one.  It returns a pointer
       to the X Visual structure for the visual and stores the number of bits per pixel for it at *depthPtr.  If string is unrecognizable or if no
       suitable  visual could be found, then NULL is returned and Tk_GetVisual leaves an error message in interp->result.  If colormap is non-NULL
       then Tk_GetVisual also locates an appropriate colormap for use with the result visual and stores its X identifier at *colormapPtr.

       The string argument specifies the desired visual in one of the following ways:

       class depth    The string consists of a class name followed by an integer depth, with  any  amount  of  white  space  (including  none)	in
		      between.	 class	selects  what sort of visual is desired and must be one of directcolor, grayscale, greyscale, pseudocolor,
		      staticcolor, staticgray, staticgrey, or truecolor, or a unique abbreviation.  depth specifies how many bits  per	pixel  are
		      needed for the visual.  If possible, Tk_GetVisual will return a visual with this depth; if there is no visual of the desired
		      depth then Tk_GetVisual looks first for a visual with greater depth, then one with less depth.

       default	      Use the default visual for tkwin's screen.

       pathName       Use the visual for the window given by pathName.	pathName must be the name of a window on the same screen as tkwin.

       number	      Use the visual whose X identifier is number.

       best ?depth?   Choose the "best possible" visual, using the following rules, in decreasing order of priority:

		      (a)    a visual that has exactly the desired depth is best, followed by a visual with greater depth than requested  (but	as
			     little extra as possible), followed by a visual with less depth than requested (but as great a depth as possible);

		      (b)    if no depth is specified, then the deepest available visual is chosen;

		      (c)    pseudocolor  is  better  than truecolor or directcolor, which are better than staticcolor, which is better than stat-
			     icgray or grayscale;

		      (d)    the default visual for the screen is better than any other visual.

CREDITS

       The idea for Tk_GetVisual, and the first implementation, came from Paul Mackerras.
