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.
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.
