.SH "WIDGET-SPECIFIC OPTIONS"
|
|
.OP \-background background Background
|
|
This option is the same as the standard \fBbackground\fR 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.
|
|
.OP \-class 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 \fBclass\fR option may not be changed with the \fBconfigure\fR
|
|
widget command.
|
|
.OP \-colormap colormap Colormap
|
|
Specifies a colormap to use for the window.
|
|
The value may be either \fBnew\fR, 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 \fIpathName\fR), in which case the new window will use the colormap
|
|
from the specified window.
|
|
If the \fBcolormap\fR option is not specified, the new window
|
|
uses the default colormap of its screen.
|
|
This option may not be changed with the \fBconfigure\fR
|
|
widget command.
|
|
.OP \-height height Height
|
|
Specifies the desired height for the window in any of the forms
|
|
acceptable to \fBTk_GetPixels\fR.
|
|
If this option is less than or equal to zero then the window will
|
|
not request any size at all.
|
|
.OP \-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 \fBconfigure\fR
|
|
widget command.
|
|
.OP \-visual visual Visual
|
|
Specifies visual information for the new window in any of the
|
|
forms accepted by \fBTk_GetVisual\fR.
|
|
If this option is not specified, the new window will use the default
|
|
visual for its screen.
|
|
The \fBvisual\fR option may not be modified with the \fBconfigure\fR
|
|
widget command.
|
|
.OP \-width width Width
|
|
Specifies the desired width for the window in any of the forms
|
|
acceptable to \fBTk_GetPixels\fR.
|
|
If this option is less than or equal to zero then the window will
|
|
not request any size at all.

.SH DESCRIPTION
|
|
.PP
|
|
The \fBtoplevel\fR command creates a new toplevel widget (given
|
|
by the \fIpathName\fR 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 \fBtoplevel\fR command returns the
|
|
path name of the new window.
|
|
.PP
|
|
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.
|
|
|
|
.SH "WIDGET COMMAND"
|
|
.PP
|
|
The \fBtoplevel\fR 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:
|
|
.CS
|
|
\fIpathName option \fR?\fIarg arg ...\fR?
|
|
.CE
|
|
\fIPathName\fR is the name of the command, which is the same as
|
|
the toplevel widget's path name. \fIOption\fR and the \fIarg\fRs
|
|
determine the exact behavior of the command. The following
|
|
commands are possible for toplevel widgets:
|
|
.TP
|
|
\fIpathName \fBcget\fR \fIoption\fR
|
|
Returns the current value of the configuration option given
|
|
by \fIoption\fR.
|
|
\fIOption\fR may have any of the values accepted by the \fBtoplevel\fR
|
|
command.
|
|
.TP
|
|
\fIpathName \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR?
|
|
Query or modify the configuration options of the widget.
|
|
If no \fIoption\fR is specified, returns a list describing all of
|
|
the available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for
|
|
information on the format of this list). If \fIoption\fR is specified
|
|
with no \fIvalue\fR, 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 \fIoption\fR is specified). If
|
|
one or more \fIoption\-value\fR 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.
|
|
\fIOption\fR may have any of the values accepted by the \fBtoplevel\fR
|
|
command.
|
|
|
|
.SH BINDINGS
|
|
.PP
|
|
When a new toplevel is created, it has no default event bindings:
|
|
toplevels are not intended to be interactive.
