-highlightbackground -padx -takefocus
See the options manual entry for details on the standard
options.
[-background 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. [-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.
[-colormap 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
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
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.
[-menu 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. [-use
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
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 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.
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.
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.
When a new toplevel is created, it has no default event bindings: toplevels are
not intended to be interactive.
