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.

Grid is one of several Geometry Managers. Some others are pack and place.
Grid is excellent for many kinds of common GUI forms, because it arranges widgets in nice rows and columns, and handles resizing quite nicely.
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 1For a little more complex example, see A little spreadsheet.
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 Services...
