options - Standard options supported by widgets
<H3><A NAME="M3">DESCRIPTION</A></H3>
This manual entry describes the common configuration options supported
by widgets in the Tk toolkit.  Every widget does not necessarily support
every option (see the manual entries for individual widgets for a list
of the standard options supported by that widget), but if a widget does
support an option with one of the names listed below, then the option
has exactly the effect described below.
<P>
In the descriptions below, ``Command-Line Name'' refers to the
switch used in class commands and <B>configure</B> widget commands to
set this value.  For example, if an option's command-line switch is
<B>-foreground</B> and there exists a widget <B>.a.b.c</B>, then the
command
<PRE><B>.a.b.c  configure  -foreground black</B></PRE>
may be used to specify the value <B>black</B> for the option in the
the widget <B>.a.b.c</B>.  Command-line switches may be abbreviated,
as long as the abbreviation is unambiguous.
``Database Name'' refers to the option's name in the option database (e.g.
in .Xdefaults files).  ``Database Class'' refers to the option's class value
in the option database.
<DL>
<DT>Command-Line Name: <B><A NAME="M-activebackground">-activebackground</A></B>
<DT>Database Name: <B>activeBackground</B>
<DT>Database Class: <B>Foreground</B>
<DD>Specifies background color to use when drawing active elements.
An element (a widget or portion of a widget) is active if the
mouse cursor is positioned over the element and pressing a mouse button
will cause some action to occur.
If strict Motif compliance has been requested by setting the
<B>tk_strictMotif</B> variable, this option will normally be
ignored;  the normal background color will be used instead.
For some elements on Windows and Macintosh systems, the active color
will only be used while mouse button 1 is pressed over the element.
<P><DT>Command-Line Name: <B><A NAME="M-activeborderwidth">-activeborderwidth</A></B>
<DT>Database Name: <B>activeBorderWidth</B>
<DT>Database Class: <B>BorderWidth</B>
<DD>Specifies a non-negative value indicating
the width of the 3-D border drawn around active elements.  See above for
definition of active elements.
The value may have any of the forms acceptable to <B><A HREF="../TkLib/GetPixels.htm">Tk_GetPixels</A></B>.
This option is typically only available in widgets displaying more
than one element at a time (e.g. menus but not buttons).
<P><DT>Command-Line Name: <B><A NAME="M-activeforeground">-activeforeground</A></B>
<DT>Database Name: <B>activeForeground</B>
<DT>Database Class: <B>Background</B>
<DD>Specifies foreground color to use when drawing active elements.
See above for definition of active elements.
<P><DT>Command-Line Name: <B><A NAME="M-anchor">-anchor</A></B>
<DT>Database Name: <B>anchor</B>
<DT>Database Class: <B>Anchor</B>
<DD>Specifies how the information in a widget (e.g. text or a bitmap)
is to be displayed in the widget.
Must be one of the values <B>n</B>, <B>ne</B>, <B>e</B>, <B>se</B>,
<B>s</B>, <B>sw</B>, <B>w</B>, <B>nw</B>, or <B>center</B>.
For example, <B>nw</B> means display the information such that its
top-left corner is at the top-left corner of the widget.
<P><DT>Command-Line Name: <B><A NAME="M-background">-background or -bg</A></B>
<DT>Database Name: <B>background</B>
<DT>Database Class: <B>Background</B>
<DD>Specifies the normal background color to use when displaying the
widget.
<P><DT>Command-Line Name: <B><A NAME="M-bitmap">-bitmap</A></B>
<DT>Database Name: <B>bitmap</B>
<DT>Database Class: <B>Bitmap</B>
<DD>Specifies a bitmap to display in the widget, in any of the forms
acceptable to <B><A HREF="../TkLib/GetBitmap.htm">Tk_GetBitmap</A></B>.
The exact way in which the bitmap is displayed may be affected by
other options such as <B>anchor</B> or <B>justify</B>.
Typically, if this option is specified then it overrides other
options that specify a textual value to display in the widget;
the <B>bitmap</B> option may be reset to an empty string to re-enable
a text display.
In widgets that support both <B>bitmap</B> and <B>image</B> options,
<B>image</B> will usually override <B>bitmap</B>.
<P><DT>Command-Line Name: <B><A NAME="M-borderwidth">-borderwidth or -bd</A></B>
<DT>Database Name: <B>borderWidth</B>
<DT>Database Class: <B>BorderWidth</B>
<DD>Specifies a non-negative value indicating the width
of the 3-D border to draw around the outside of the widget (if such a
border is being drawn;  the <B>relief</B> option typically determines
this).  The value may also be used when drawing 3-D effects in the
interior of the widget.
The value may have any of the forms acceptable to <B><A HREF="../TkLib/GetPixels.htm">Tk_GetPixels</A></B>.
<P><DT>Command-Line Name: <B><A NAME="M-cursor">-cursor</A></B>
<DT>Database Name: <B>cursor</B>
<DT>Database Class: <B>Cursor</B>
<DD>Specifies the mouse cursor to be used for the widget.
The value may have any of the forms acceptable to <B><A HREF="../TkLib/GetCursor.htm">Tk_GetCursor</A></B>.
<P><DT>Command-Line Name: <B><A NAME="M-disabledforeground">-disabledforeground</A></B>
<P><DT>Command-Line Name: <B><A NAME="M-disabledbackground">-disabledbackground</A></B>
<DT>Database Name: <B>disabledBackground</B>
<DT>Database Class: <B>DisabledBackground</B>
<DD>Specifies background color to use when drawing a disabled element.
If the option is specified as an empty string (which is typically the
case on monochrome displays), disabled elements are drawn with the
normal background color but they are dimmed by drawing them
with a stippled fill pattern.
<DT>Database Name: <B>disabledForeground</B>
<DT>Database Class: <B>DisabledForeground</B>
<DD>Specifies foreground color to use when drawing a disabled element.
If the option is specified as an empty string (which is typically the
case on monochrome displays), disabled elements are drawn with the
normal foreground color but they are dimmed by drawing them
with a stippled fill pattern.
<P><DT>Command-Line Name: <B><A NAME="M-exportselection">-exportselection</A></B>
<DT>Database Name: <B>exportSelection</B>
<DT>Database Class: <B>ExportSelection</B>
<DD>Specifies whether or not a selection in the widget should also be
the X selection.
The value may have any of the forms accepted by <B><A HREF="../TclLib/GetInt.htm">Tcl_GetBoolean</A></B>,
such as <B>true</B>, <B>false</B>, <B>0</B>, <B>1</B>, <B>yes</B>, or <B>no</B>.
If the selection is exported, then selecting in the widget deselects
the current X selection, selecting outside the widget deselects any
widget selection, and the widget will respond to selection retrieval
requests when it has a selection.  The default is usually for widgets
to export selections.
<P><DT>Command-Line Name: <B><A NAME="M-font">-font</A></B>
<DT>Database Name: <B><A HREF="../TkCmd/font.htm">font</A></B>
<DT>Database Class: <B><A HREF="../TkCmd/font.htm">Font</A></B>
<DD>Specifies the font to use when drawing text inside the widget.
<P><DT>Command-Line Name: <B><A NAME="M-foreground">-foreground or -fg</A></B>
<DT>Database Name: <B>foreground</B>
<DT>Database Class: <B>Foreground</B>
<DD>Specifies the normal foreground color to use when displaying the widget.
<P><DT>Command-Line Name: <B><A NAME="M-highlightbackground">-highlightbackground</A></B>
<DT>Database Name: <B>highlightBackground</B>
<DT>Database Class: <B>HighlightBackground</B>
<DD>Specifies the color to display in the traversal highlight region when
the widget does not have the input focus.
<P><DT>Command-Line Name: <B><A NAME="M-highlightcolor">-highlightcolor</A></B>
<DT>Database Name: <B>highlightColor</B>
<DT>Database Class: <B>HighlightColor</B>
<DD>Specifies the color to use for the traversal highlight rectangle that is
drawn around the widget when it has the input focus.
<P><DT>Command-Line Name: <B><A NAME="M-highlightthickness">-highlightthickness</A></B>
<DT>Database Name: <B>highlightThickness</B>
<DT>Database Class: <B>HighlightThickness</B>
<DD>Specifies a non-negative value indicating the width of the highlight
rectangle to draw around the outside of the widget when it has the
input focus.
The value may have any of the forms acceptable to <B><A HREF="../TkLib/GetPixels.htm">Tk_GetPixels</A></B>.
If the value is zero, no focus highlight is drawn around the widget.
<P><DT>Command-Line Name: <B><A NAME="M-image">-image</A></B>
<DT>Database Name: <B>image</B>
<DT>Database Class: <B>Image</B>
<DD>Specifies an image to display in the widget, which must have been
created with the <B><A HREF="../TkCmd/image.htm">image create</A></B> command.
Typically, if the <B>image</B> option is specified then it overrides other
options that specify a bitmap or textual value to display in the widget;
the <B>image</B> option may be reset to an empty string to re-enable
a bitmap or text display.
<P><DT>Command-Line Name: <B><A NAME="M-insertbackground">-insertbackground</A></B>
<DT>Database Name: <B>insertBackground</B>
<DT>Database Class: <B>Foreground</B>
<DD>Specifies the color to use as background in the area covered by the
insertion cursor.  This color will normally override either the normal
background for the widget (or the selection background if the insertion
cursor happens to fall in the selection).
<P><DT>Command-Line Name: <B><A NAME="M-insertborderwidth">-insertborderwidth</A></B>
<DT>Database Name: <B>insertBorderWidth</B>
<DT>Database Class: <B>BorderWidth</B>
<DD>Specifies a non-negative value indicating the width
of the 3-D border to draw around the insertion cursor.
The value may have any of the forms acceptable to <B><A HREF="../TkLib/GetPixels.htm">Tk_GetPixels</A></B>.
<P><DT>Command-Line Name: <B><A NAME="M-insertofftime">-insertofftime</A></B>
<DT>Database Name: <B>insertOffTime</B>
<DT>Database Class: <B>OffTime</B>
<DD>Specifies a non-negative integer value indicating the number of
milliseconds the insertion cursor should remain ``off'' in each blink cycle.
If this option is zero then the cursor doesn't blink:  it is on
all the time.
<P><DT>Command-Line Name: <B><A NAME="M-insertontime">-insertontime</A></B>
<DT>Database Name: <B>insertOnTime</B>
<DT>Database Class: <B>OnTime</B>
<DD>Specifies a non-negative integer value indicating the number of
milliseconds the insertion cursor should remain ``on'' in each blink cycle.
