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. 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 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.
