.AP "const char" *string in
Potentially multi-line string whose dimensions are to be computed and
stored in the text layout.  The \fIstring\fR must remain valid for the
lifetime of the text layout.
.AP int numChars in
The number of characters to consider from \fIstring\fR.  If
\fInumChars\fR is negative, then assumes \fIstring\fR is null
terminated and uses \fBTcl_NumUtfChars\fR to determine the length of
\fIstring\fR.
.AP int wrapLength in
Longest permissible line length, in pixels.  Lines in \fIstring\fR will
automatically be broken at word boundaries and wrapped when they reach
this length.  If \fIwrapLength\fR is too small for even a single
character to fit on a line, it will be expanded to allow one character to

\fBTk_PointToChar\fR uses the information in \fIlayout\fR to determine the
character closest to the given point.  The point is specified with respect
to the upper-left hand corner of the \fIlayout\fR, which is considered to be
located at (0, 0).  Any point whose \fIy\fR-value is less that 0 will be
considered closest to the first character in the text layout; any point
whose \fIy\fR-value is greater than the height of the text layout will be
considered closest to the last character in the text layout.  Any point
whose \fIx\fR-value is negative will be considered closest to the first
character on that line; any point whose \fIx\fR-value is greater than the
width of the text layout will be considered closest to the last character on
that line.  The return value is the index of the character that was closest
to the point, or one more than the index of any character (to indicate that
the point was after the end of the string and that the corresponding caret
would be at the end of the string).  Given a \fIlayout\fR with no characters,
the value 0 will always be returned, referring to a hypothetical zero-width

Specifies an increment for horizontal scrolling, in any of the usual forms
permitted for screen distances. If the value of this option is greater
than zero, the horizontal view in the window will be constrained so that
the canvas x coordinate at the left edge of the window is always an even
multiple of \fBxScrollIncrement\fR; furthermore, the units for scrolling
(e.g., the change in view when the left and right arrows of a scrollbar
are selected) will also be \fBxScrollIncrement\fR. If the value of
this option is negative or zero, then horizontal scrolling
is unconstrained.
.OP \-yscrollincrement yScrollIncrement ScrollIncrement
Specifies an increment for vertical scrolling, in any of the usual forms
permitted for screen distances. If the value of this option is greater
than zero, the vertical view in the window will be constrained so that
the canvas y coordinate at the top edge of the window is always an even
multiple of \fByScrollIncrement\fR; furthermore, the units for scrolling
(e.g., the change in view when the top and bottom arrows of a scrollbar
are selected) will also be \fByScrollIncrement\fR. If the value of

.IP \fInumber\fR 10
A decimal number giving the position of the desired character
within the text item.
0 refers to the first character, 1 to the next character, and
so on. If indexes are odd for lines and polygons, they will be
automatically decremented by one.
A negative number  is treated as if it were zero, and a
number greater than the length of the text item is treated
as if it were equal to the length of the text item. For
polygons, negative numbers or numbers greater than the length
of the coordinate list will be adjusted by adding or subtracting
the length until the result is between zero and the length,
inclusive.
.IP \fBend\fR 10
Refers to the character or coordinate just after the last one
in the item (same as the number of characters or coordinates
in the item).

the dialog, to the left of the text.
If this is an empty string then no bitmap is displayed in the dialog.
.IP \fIdefault\fR
If this is an integer greater than or equal to zero, then it gives
the index of the button that is to be the default button for the dialog
(0 for the leftmost button, and so on).
If negative or an empty string then there will not be any default
button.
.IP \fIstring\fR
There will be one button for each of these arguments.
Each \fIstring\fR specifies text to display in a button,
in order from left to right.

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

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"

.OP \-wraplength wrapLength WrapLength
For widgets that can perform word-wrapping, this option specifies
the maximum line length.
Lines that would exceed this length are wrapped onto the next line,
so that no line is longer than the specified length.
The value may be specified in any of the standard forms for
screen distances.
If this value is negative or zero then no wrapping is done:  lines
will break only at newline characters in the text.
.OP \-xscrollcommand xScrollCommand ScrollCommand
Specifies the prefix for a command used to communicate with horizontal
scrollbars.
When the view in the widget's window changes (or
whenever anything else occurs that could change the display in a
scrollbar, such as a change in the total size of the widget's

as an empty string, no label is displayed.
.OP \-length length Length
Specifies the desired long dimension of the scale in screen units
(i.e. any of the forms acceptable to \fBTk_GetPixels\fR).
For vertical scales this is the scale's height;  for horizontal scales
it is the scale's width.
.OP \-resolution resolution Resolution
A real value specifying the resolution for the scale.
If this value is greater than zero then the scale's value will always be
rounded to an even multiple of this value, as will
the endpoints of the scale.  If the value is negative then no
rounding occurs.  Defaults to 1 (i.e., the value will be integral).
.OP \-showvalue showValue ShowValue
Specifies a boolean value indicating whether or not the current
value of the scale is to be displayed.
.OP \-sliderlength sliderLength SliderLength
Specifies the size of the slider, measured in screen units along the slider's
long dimension.  The value may be specified in any of the forms acceptable
