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.
