Grid is one of several [Geometry Managers]. Some others are [pack] and [place].

The [Book Practical Programming in Tcl and Tk, Fourth Edition] contains an excellent introduction into the grid command which is available online at [http://www.beedub.com/book/].

Grid is excellent for many kinds of common GUI forms, because it arranges widgets in nice rows and columns, and handles resizing quite nicely.

[DKF] - The term ''Grid'' also refers to the very high end of resource sharing systems over the internet which it is likely that people will be hearing a lot more about in the future, especially in phrases like [Grid Service]s...


TclGlobus is a project to allow Grid interfaces in Tcl: http://tclglobus.ligo.caltech.edu/

'''grid''' ''slave ?slave ...? ?options?''

'''[grid bbox]''' ''master ?column row? ?column2 row2?''

'''[grid columnconfigure]''' ''master index ?-option value...?''

'''[grid configure]''' ''slave ?slave ...? ?options?''

'''[grid forget]''' ''slave ?slave ...?''

'''[grid info]''' ''slave''

'''[grid location]''' ''master x y''

'''[grid propagate]''' ''master ?boolean?''

'''[grid remove]''' ''slave ?slave ...?''

'''[grid rowconfigure]''' ''master index ?-option value...?''

'''[grid size]''' ''master''

'''[grid slaves]''' ''master ?-option value?''

If the first argument to '''grid''' is suitable as the first slave argument to [grid configure], 
either a window name (any value starting with '''.''') or one of the characters '''x''' or '''^''' 
(see the "RELATIVE PLACEMENT" section below), then the command is processed in the same way as [grid configure].

A Simple example is a panel with just a few labels and entries.

    package require Tk

    foreach field {Name Address City State Phone} {
	#  Create a couple of widgets
	set l [label .lab$field -text $field]
	set e [entry .ent$field -justify right ]
	#  Assign both to a row in the grid
	grid $l $e -padx 4 -pady 4
	#  Then adjust how they appear
	grid $l -sticky e
	grid $e -sticky ew
    }

    # X-resize is done by the entry column
    grid columnconfigure . 1 -weight 1

    #  Y-resize should be at the bottom...
    set lastrow [lindex [grid size .] 1]
    grid rowconfigure . $lastrow -weight 1
