WIDGET-SPECIFIC OPTIONS
Name: background |
Class: Background |
Command-Line Switch:-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.
Name: class |
Class: Class |
Command-Line Switch:-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.
Name: colormap
Class: Colormap
Command-Line Switch:-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.
Name: height
Class: Height
Command-Line Switch:-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.

Name: None |
Class: None |
Command-Line Switch:-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.
Name: visual |
Class: Visual |
Command-Line Switch:-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.
Name: width
Class: Width
Command-Line Switch:-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.
