See the options manual entry for details on the standard options.
[-background background]
This option is the same as the standard │
background option except that its value may also be
specified as an │ empty string. In this
case, the widget will display no background or
│ border, and no colors will be consumed
from its colormap for its │ background and
border. [-class class] Specifies a class
for the │ window. This class will be used
when querying the option database for │ the
window’s other options, and it will also be used later
for other │ purposes such as bindings. The
class option may not be changed with
│ the configure widget command.
[-colormap colormap] Specifies a
│ colormap to use for the window. The value
may be either new, in which │ case a
new colormap is created for the window and its children, or
the │ name of another window (which must be
on the same screen and have the │ same
visual as pathName), in which case the new window
will use the │ colormap from the specified
window. If the colormap option is not
│ specified, the new window uses the
default colormap of its screen. │ This
option may not be changed with the configure widget
command. [-height height] Specifies the
desired height for the window in any of the forms acceptable
to Tk_GetPixels. If this option is less than or equal
to zero then the window will not request any size at all.
[-screen ] Specifies the screen on which to
place the new window. Any │ valid screen
name may be used, even one associated with a different
│ display. Defaults to the same screen as
its parent. This option is │ special in
that it may not be specified via the option database, and it
│ may not be modified with the
configure widget command. │
[-visual visual] Specifies visual
information for the new window in any │ of
the forms accepted by Tk_GetVisual. If this option is
not │ specified, the new window will use
the default visual for its screen. │ The
visual option may not be modified with the
configure widget │ command.
[-width width] Specifies the desired
width for the window in any of the forms acceptable to
Tk_GetPixels. If this option is less than or equal to
zero then the window will not request any size at all.

The toplevel command creates a new toplevel widget (given by the pathName argument). Additional options, described above, may be specified on the command line or in the option database to configure aspects of the toplevel such as its background color and relief. The toplevel command returns the path name of the new window.
A toplevel is similar to a frame except that it is created as a top-level window: its X parent is the root window of a screen rather than the logical parent from its path name. The primary purpose of a toplevel is to serve as a container for dialog boxes and other collections of widgets. The only visible features of a toplevel are its background color and an optional 3-D border to make the toplevel appear raised or sunken.
The toplevel command creates a new Tcl command whose name is the same as the path name of the toplevel’s window. This command may be used to invoke various operations on the widget. It has the following general form:
pathName option ?arg arg ...?
PathName is the name of
the command, which is the same as the toplevel
widget’s path name. Option and the args
determine the exact behavior of the command. The following
commands are possible for toplevel widgets:
pathName cget option
Returns the current value of the configuration option given by │ option. Option may have any of the values accepted by the │ toplevel command.
pathName configure ?option? ?value option value ...?
Query or modify the configuration options of the widget. If no option is specified, returns a list describing all of the available options for pathName (see Tk_ConfigureInfo for information on the format of this list). If option is specified with no value, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no option is specified). If one or more option-value pairs are specified, then the command modifies the given widget option(s) to have the given value(s); in this case the command returns an empty string. Option may have any of the values accepted by the toplevel command.
When a new toplevel is created, it has no default event bindings: toplevels are not intended to be interactive.
