See the options manual entry for details on the standard
options.
Command-Line Name: -background
Database Name: background
Database Class: 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.
Command-Line Name: -class
Database Name: class
Database 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.
Command-Line Name: -colormap
Database Name: colormap
Database Class: 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 same colormap as its
parent. This option may not be changed with the configure widget
command.
Command-Line Name: -height
Database Name: height
Database Class: 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.
Command-Line Name: -labelanchor
Database Name: labelAnchor
Database Class: LabelAnchor
- Specifies where to place the label. A label is only displayed if the
-text option is not the empty string. Valid values for this option
are (listing them clockwise) nw, n, ne, en,
e, es, se, s,sw, ws, w
and wn. The default value is nw.
Command-Line Name: -labelwidget
Database Name: labelWidget
Database Class: LabelWidget
- Specifies a widget to use as label. This overrides any -text
option. The widget must exist before being used as -labelwidget and
if it is not a descendant of this window, it will be raised above it in
the stacking order.
Command-Line Name: -visual
Database Name: visual
Database Class: 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 same visual as its parent. The -visual option
may not be modified with the configure widget command.
Command-Line Name: -width
Database Name: width
Database Class: 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 labelframe command creates a new window (given by the
pathName argument) and makes it into a labelframe widget. Additional
options, described above, may be specified on the command line or in the
option database to configure aspects of the labelframe such as its
background color and relief. The labelframe command returns the path
name of the new window.
A labelframe is a simple widget. Its primary purpose is to act as
a spacer or container for complex window layouts. It has the features of a
frame plus the ability to display a label.
The labelframe command creates a new Tcl command whose name
is the same as the path name of the labelframe'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 labelframe
widget's path name. Option and the args determine the exact
behavior of the command. The following commands are possible for frame
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
labelframe 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 labelframe command.
When a new labelframe is created, it has no default event
bindings: labelframes are not intended to be interactive.
This shows how to build part of a GUI for a hamburger vendor. The
labelframe widgets are used to organize the available choices by the
kinds of things that the choices are being made over.
