Synopsis#

toplevel pathName ?options?

Standard Options#

See the options manual entry for details on the standard options.

Widget-specific options#

-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. An empty background will disable drawing the background image.

-backgroundimage#

Database name	backgroundImage
Database class	BackgroundImage

This specifies an image to display on the toplevel's background within the border of the toplevel (i.e., the image will be clipped by the toplevel's highlight ring and border, if either are present) on top of the background; subwidgets of the toplevel will be drawn on top. The image must have been created with the image create command. If specified as the empty string, no image will be displayed.

-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.

-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.

-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.

-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 negative or zero then the window will not request any size at all.

-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.

-screen#

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.

-tile#

Database name	tile
Database class	Tile

This specifies how to draw the background image (see -backgroundimage) on the toplevel. If true (according to Tcl_GetBoolean), the image will be tiled to fill the whole toplevel, with the origin of the first copy of the image being the top left of the interior of the toplevel. If false (the default), the image will be centered within the toplevel.

-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.

-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.

-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 negative or 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 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 ...?

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.
