WIDGET-SPECIFIC 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.

DESCRIPTION

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

METHODS

       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:

WIDGET-SPECIFIC METHODS

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.

COMPONENTS

       Name:           shellchildsite

              entry for details on the shellchildsite component item.

        package require Iwidgets 4.0
        iwidgets::shell .sh -modality application -padx 20 -pady 20 -title Shell
