See the "Toplevel" manual entry for details on the above
inherited options.

Name:           height
Class:          Height
Command‐Line Switch:           ‐height
Specifies the height of the shell.  The value may be specified in
any of the forms acceptable to Tk_GetPixels.  A value of zero
causes the height to be adjusted to the required value based on
the size requests of the components placed in the childsite.
Otherwise, the height is fixed.  The default is zero.  NOTE: This
may cause some amount of flickering on slower machines.  To
prevent it simply set the width and height to a appropriate
value.
Name:           master
Class:          Window
Command‐Line Switch:           ‐master
Defines the shell as being a transient window with the master
window given by the master option.  The master window should be
either another existing toplevel window or {} for no master.  The
default is {} for shells and "." for dialogs.
Name:           modality
Class:          Modality
Command‐Line Switch:           ‐modality
Allows the shell to grab control of the screen in one of three
different ways: application, system, or none.  Application modal
prevents any other toplevel windows within the application which
are direct children of ’.’ from gaining focus.  System modal
locks the screen and prevents all windows from gaining focus
regardless of application.  A modality of none performs no grabs
at all.  The default is none.
Name:           padX
Class:          Pad
Command‐Line Switch:           ‐padx
Specifies a padding distance for the childsite in the X‐direction
in any of the forms acceptable to Tk_GetPixels.  The default is
10.
Name:           padY
Class:          Pad
Command‐Line Switch:           ‐pady
Specifies a padding distance for the childsite in the Y‐direction
in any of the forms acceptable to Tk_GetPixels.  The default is
10.
Name:           width
Class:          Width
Command‐Line Switch:           ‐width
Specifies the width of the shell.  The value may be specified in
any of the forms acceptable to Tk_GetPixels.  A value of zero
causes the width to be adjusted to the required value based on
the size requests of the components placed in the childsite.
Otherwise, the width is fixed.  The default is zero.  NOTE: This
may cause some amount of flickering on slower machines.  To
prevent it simply set the width and height to a appropriate
value.

The iwidgets::shell command creates a shell which is a top level
widget which supports modal operation.

The iwidgets::shell command create a new Tcl command whose name
is pathName.  This command may be used to invoke various
operations on the widget.  It has the following general form:
pathName option ?arg arg ...?  Option and the args determine the
exact behavior of the command.  The following commands are
possible for shell widgets: pathName activate Display the shell
and wait based on the modality.  For application and system modal
activations, perform a grab operation, and wait for the result.
The result may be returned via an argument to the deactivate
method.  pathName center ?widget?  Centers the shell with respect
to another widget.  The widget argument is optional.  If
provided, it should be the path of another widget with to center
upon.  If absent, then the shell will be centered on the screen
as a whole.  pathName cget option Returns the current value of
the configuration option given by option.  Option may have any of
the values accepted by the iwidgets::shell command.  pathName
childsite Returns the pathname of the child site widget.
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 iwidgets::shell command.  pathName deactivate
?arg?  Deactivate the display of the shell.  The method takes an
optional argument to be passed to the activate method which
returns the value.  The optional argument is only effective for
application and system modal dialogs.

Name:           shellchildsite
Class:          frame
The shellchildsite component is the user child site for the
shell.  See the "frame" widget manual entry for details on the
shellchildsite component item.
