NAME ^

Tk::Labelframe - Create and manipulate Labelframe widgets

SYNOPSIS ^

$labelframe = $parent->Labelframe(?options?);

 -borderwidth -highlightbackground -pady
 -cursor      -highlightcolor      -relief
 -font        -highlightthickness  -takefocus
 -foreground  -padx                -text

WIDGET-SPECIFIC OPTIONS ^

Option: -background
Name: background
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.

Option: -class
Name: 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 class option may not be changed with the configure method.

Option: -colormap
Name: colormap
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 $widget), 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 method.

Option: -container
Name: container
Class: 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 -use 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 configure method.

Option: -height
Name: height
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.

Option: -labelanchor
Name: labelAnchor
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.

Option: -labelwidget
Name: labelWidget
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.

Option: -visual
Name: visual
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 method.

Option: -width
Name: width
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.

DESCRIPTION ^

The Labelframe method creates a new window (given by the $labelframe 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.

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.

WIDGET METHODS ^

The Labelframe method may be used to invoke various operations on the widget. It has the following general form:

 $widget->method(?arg arg ...?);

The following methods are possible for Labelframe widgets:

$widget->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.

$widget->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 $widget (see Tk::configure 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.

BINDINGS ^

When a new Labelframe is created, it has no default event bindings: Labelframes are not intended to be interactive.
