widget associated with the tabset. When a user selects a tab, a Tcl command
is invoked. The actual command consists of this option followed by a space
and a number. The number is the numerical index of the tab that has been
selected.
of true means constrain tabs to be equal sized. A value of false
allows each tab to size based on the text label size. The value
may have any of the forms accepted by the Tcl_GetBoolean, such as
true, false, 0, 1, yes, or no.

outside edge of the tabset than the unselected tabs. A value of

For vertically positioned tabs, this is the amount of space between the top of the tabset and the top of the first tab. This value may change if the user performs a MButton-2 scroll on the tabs.

argument) and makes it into a tabset widget. Additional options, described above may be specified on the command line or in the option database to configure aspects of the tabset such as its colors, font, and text. The tabset command returns its pathName argument. At the time this command is invoked, there must not exist a window named pathName, but pathName's parent must exist.
plays these tabs in a row or column depending on it tabpos. When
a tab is clicked on, it becomes the only tab in the tab set that
is selected. All other tabs are deselected. The Tcl command pre-
fix associated with this tab (through the command tab configure
option) is invoked with the tab index number appended to its
argument list. This allows the tabset to control another widget
such as a Notebook.
draws an edge boundary along one of its edges. This edge is known
as the attachment edge. This edge location is dependent on the
value of tabPos. For example, if tabPos is s, the attachment edge
wil be on the top side of the tabset (in order to attach to the
bottom or south side of its attached widget). The selected tab is

pattern
form is used. Pattern is pattern-matched against the label of
each tab in the tabset, in order from the first to the last tab,
until a matching entry is found. The rules of Tcl_StringMatch are
used.
pathName add ?option value option value ...?
pathName. If additional arguments are present, they specify any
of the following options:
-angle value
of the tab. An angle of 0 specifies square tabs. Valid ranges are
0 to 45 degrees inclusive. Default is 15 degrees. If this option
is specified as an empty string (the default), then the angle
option for the overall tabset is used.
-background value
are in their normal state (unselected). If this option is speci-
fied as an empty string (the default), then the background option
for the overall tabset is used.
-bevelamount value
0 results in square tabs. A bevelAmount of 4, means that the tab
will be drawn with angled corners that cut in 4 pixels from the
edge of the tab. The default is 0. This is generally only set at
the tabset configuration level. Tabs normally will want to share
the same bevelAmount.
-bitmap value
the tab. Bitmap may be of any of the forms accepted by Tk_Get-
-disabledforeground value
when tabs are in their disable state. If this option is specified
as an empty string (the default), then the disabledforeground
option for the overall tabset is used.
-font value
this option is specified as an empty string then the font option
for the overall tabset is used.
-foreground value
when tabs are in their normal unselected state. If this option is
specified as an empty string (the default), then the foreground
option for the overall tabset is used.
-image value
the tab. Image must have been created with the image create com-
mand. Typically, if the image option is specified then it over-
rides other options that specify a bitmap or textual value to
display in the widget; the image option may be reset to an empty
string to re-enable a bitmap or text display.
-label value
value is set, the bitmap option is overridden and this option is
used instead. This label serves as an additional identifier used
to reference the tab. This label may be used for the index value
in widget commands.
-selectbackground value
tab. If this option is specified as an empty string (the
default), then the selectBackground option for the overall tabset
is used.
-selectforeground value
tab. If this option is specified as an empty string (the
default), then the selectForeground option for the overall tabset
is used.
-padx value
request for a tab around its label in the X-direction. When computing how large a window it needs, the tab will add this amount to the width it would normally need The tab will end up with extra internal space to the left and right of its text label. This value may have any of the forms acceptable to Tk_Get-
default), then the padX option for the overall tabset is used
-pady value
request for a tab around its label in the Y-direction. When com- puting how large a window it needs, the tab will add this amount to the height it would normally need The tab will end up with extra internal space to the top and bottom of its text label.
then the padY option for the overall tabset is used
-state value
be selectable. Specifying disabled disables the this tab causing
its tab label to be drawn in the disabledForeground color. The
tab will not respond to events until the state is set back to
normal.
pathName configure ?option? ?value option value ...?
option is specified, returns a list describing all of the avail-
able 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 tabset command.
pathName delete index1 ?index2?
index2 is omitted then it defaults to index1. Returns an empty
string.
pathName index index
pathName insert index ?option value option value ...?
pathName next
insertion order). If the currently selected tab is the last tab
in the tabset, the selection wraps around to the first tab. It
behaves as if the user selected the next tab.
pathName tabconfigure index ?option? ?value?
applies to the options for an individual tab, whereas configure
applies to the options for the tabset as a whole. Options may
have any of the values accepted by the add widget command. If
options are specified, options are modified as indicated in the
command and the command returns an empty string. If no options
are specified, returns a list describing the current options for
tab index (see Tk_ConfigureInfo for information on the format of
this list).
pathName prev
by insertion order). If the currently selected tab is the first
tab in the tabset, the selection wraps around to the last tab in
the tabset. It behaves as if the user selected the previous tab.

from the list also selects the corresponding tab.
