NAME
toplevel - Create and manipulate 'toplevel' main and popup window widgets
SYNOPSIS
toplevel pathName ?options?
STANDARD OPTIONS
-borderwidth -highlightcolor -pady
-cursor -highlightthickness -relief
-highlightbackground -padx -takefocus
See the options manual entry for details on the standard options.
WIDGET-SPECIFIC OPTIONS
Command-Line Name:-background
Database Name: background
Database Class: 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.
Command-Line Name:-class
Database Name: class
Database 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. Some window managers display the class name for windows
in their dock while some others display the window title. The -class option may
not be changed with the configure widget command.
Command-Line Name:-colormap
Database Name: colormap
Database Class: 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.
Command-Line Name:-container
Database Name: container
Database Class: Container
The value must be a boolean. If true, it means that this window will be used as a
container in which some other application will be embedded (for example, a Tk
toplevel can be embedded using the -use option). The window will support the
appropriate window manager protocols for things like geometry requests. The window
should not have any children of its own in this application. This option may not
be changed with the configure widget command.
Command-Line Name:-height
Database Name: height
Database Class: 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.
Command-Line Name:-menu
Database Name: menu
Database Class: Menu
Specifies a menu widget to be used as a menubar. On the Macintosh, the menubar will
be displayed across the top of the main monitor. On Microsoft Windows and all UNIX
platforms, the menu will appear across the toplevel window as part of the window
dressing maintained by the window manager.
Command-Line Name:-screen
Database Name:
Database Class:
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.
Command-Line Name:-use
Database Name: use
Database Class: Use
This option is used for embedding. If the value is not an empty string, it must be
the window identifier of a container window, specified as a hexadecimal string like
the ones returned by the winfo id command. The toplevel widget will be created as a
child of the given container instead of the root window for the screen. If the
container window is in a Tk application, it must be a frame or toplevel widget for
which the -container option was specified. This option may not be changed with the
configure widget command.
Command-Line Name:-visual
Database Name: visual
Database Class: 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.
Command-Line Name:-width
Database Name: width
Database Class: 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.

DESCRIPTION
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 Tk 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.
WIDGET COMMAND
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.
BINDINGS
When a new toplevel is created, it has no default event bindings: toplevels are not
intended to be interactive.
Be aware that bindings on toplevels may receive events from subwidgets.
