.SH "WIDGET-SPECIFIC OPTIONS"
.OP \-background background Background
This option is the same as the standard \fB\-background\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.
.VS "8.7, TIP262"
An empty background will disable drawing the background image.
.OP \-backgroundimage backgroundImage BackgroundImage
This specifies an image to display on the frame's background within
the border of the frame (i.e., the image will be clipped by the
frame's highlight ring and border, if either are present); subwidgets
of the frame will be drawn on top. The image must have been created
with the \fBimage create\fR command. If specified as the empty string,
no image will be displayed.
.VE "8.7, TIP262"
.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 \fB\-class\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 \fB\-colormap\fR option is not specified, the new window
uses the same colormap as its parent.
This option may not be changed with the \fBconfigure\fR
widget command.
.OP \-container 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 \fB\-use\fR 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 \fBconfigure\fR
widget command.
Note that \fB\-borderwidth\fR, \fB\-padx\fR and \fB\-pady\fR are ignored when
configured as a container since a container has no border.
.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 negative or
zero then the window will not request any size at all.  Note that this
sets the total height of the frame, any \fB\-borderwidth\fR or similar is
not added.  Normally \fB\-height\fR should not be used if a propagating
geometry manager, such as \fBgrid\fR or \fBpack\fR, is used within the
frame since the geometry manager will override the height of the frame.
.OP \-tile tile Tile
.VS "8.7, TIP262"
This specifies how to draw the background image (see
\fB\-backgroundimage\fR) on the frame.
If true (according to \fBTcl_GetBoolean\fR), the image will be tiled
to fill the whole frame, with the origin of the first copy of the
image being the top left of the interior of the frame.
If false (the default), the image will be centered within the frame.
.VE "8.7, TIP262"
.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 same
visual as its parent.
The \fB\-visual\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 negative or
zero then the window will not request any size at all.  Note that this
sets the total width of the frame, any \fB\-borderwidth\fR or similar is
not added.  Normally \fB\-width\fR should not be used if a propagating
geometry manager, such as \fBgrid\fR or \fBpack\fR, is used within the
frame since the geometry manager will override the width of the frame.

.SH DESCRIPTION
.PP
The \fBframe\fR command creates a new window (given by the
\fIpathName\fR argument) and makes it into a frame widget.
Additional
options, described above, may be specified on the command line
or in the option database
to configure aspects of the frame such as its background color
and relief.  The \fBframe\fR command returns the
path name of the new window.
.PP
A frame is a simple widget.  Its primary purpose is to act as a
spacer or container for complex window layouts.  The only features
of a frame are its background and an optional 3-D border to make the
frame appear raised or sunken.
.SH "WIDGET COMMAND"
.PP
The \fBframe\fR command creates a new Tcl command whose
name is the same as the path name of the frame's window.  This
command may be used to invoke various
operations on the widget.  It has the following general form:
.PP
.CS
\fIpathName option \fR?\fIarg ...\fR?
.CE
.PP
\fIPathName\fR is the name of the command, which is the same as
the frame widget's path name.  \fIOption\fR and the \fIarg\fRs
determine the exact behavior of the command.  The following
commands are possible for frame widgets:
.\" METHOD: cget
.TP
\fIpathName \fBcget\fI option\fR
.
Returns the current value of the configuration option given
by \fIoption\fR.
\fIOption\fR may have any of the values accepted by the \fBframe\fR
command.
.\" METHOD: configure
.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 \fBframe\fR
command.
.SH BINDINGS
.PP
When a new frame is created, it has no default event bindings:
frames are not intended to be interactive.
