WIDGET-SPECIFIC OPTIONS
Name: height
Class: Height
Command-Line Switch: -height
Specifies the height of the scrolled text as an entire unit.
The value may be specified in any of the forms acceptable to
Tk_GetPixels. Any additional space needed to display the other
components such as labels, margins, and scrollbars force the
text to be compressed. A value of zero along with the same
value for the width causes the value given for the visibleitems
option to be applied which administers geometry constraints in a
different manner. The default height is zero.
Name: hscrollMode
Class: ScrollMode
Command-Line Switch: -hscrollmode
Specifies the the display mode to be used for the horizontal
scrollbar: static, dynamic, or none. In static mode, the scroll
bar is displayed at all times. Dynamic mode displays the scroll
bar as required, and none disables the scroll bar display. The
default is static.
Name: sbWidth
Class: Width
Command-Line Switch: -sbwidth
Specifies the width of the scrollbar in any of the forms accept-
able to Tk_GetPixels.
Name: scrollMargin
Class: Margin
Command-Line Switch: -scrollmargin
Specifies the distance between the text area and scrollbar in
any of the forms acceptable to Tk_GetPixels. The default is 3
pixels.
Name: textBackground
Class: Background
Command-Line Switch: -textbackground
Specifies the background color for the text area in any of the
forms acceptable to Tk_GetColor.
Name: textFont
Class: Font
Command-Line Switch: -textfont
Specifies the font to be used in the scrolled text area.
Name: visibleitems
Class: VisibleItems
Command-Line Switch: -visibleitems
Specifies the widthxheight in characters and lines for the text.
This option is only administered if the width and height options
are both set to zero, otherwise they take precedence. The
default value is 80x24. With the visibleitems option engaged,
geometry constraints are maintained only on the text. The size
of the other components such as labels, margins, and scroll
bars, are additive and independent, effecting the overall size
of the scrolled text. In contrast, should the width and height
options have non zero values, they are applied to the scrolled
text as a whole. The text is compressed or expanded to maintain
the geometry constraints.
Name: vscrollMode
Class: ScrollMode
Command-Line Switch: -vscrollmode
Specifies the the display mode to be used for the vertical
scrollbar: static, dynamic, or none. In static mode, the scroll
bar is displayed at all times. Dynamic mode displays the scroll
bar as required, and none disables the scroll bar display. The
default is static.
Name: width
Class: Width
Command-Line Switch: -width
Specifies the width of the scrolled text as an entire unit. The
value may be specified in any of the forms acceptable to Tk_Get-
Pixels. Any additional space needed to display the other compo-
nents such as labels, margins, and scrollbars force the text to
be compressed. A value of zero along with the same value for
the height causes the value given for the visibleitems option to
be applied which administers geometry constraints in a different
manner. The default width is zero.

DESCRIPTION
The iwidgets::scrolledtext command creates a scrolled text widget with
additional options to manage the scrollbars. This includes options to
control the method in which the scrollbars are displayed, i.e. stati-
cally or dynamically. Options also exist for adding a label to the
scrolled text area and controlling its position. Import/export of
methods are provided for file I/O.
METHODS
The iwidgets::scrolledtext command creates a new Tcl command whose name
is pathName. This command may be used to invoke various operations on
the widget. It has the following general form:
pathName option ?arg arg ...?
Option and the args determine the exact behavior of the command. The
following commands are possible for scrolledtext widgets:
ASSOCIATED METHODS
bbox compare debug delete
dlineinfo get image index
insert mark scan search
see tag window xview
yview
See the "text" manual entry for details on the standard methods.
WIDGET-SPECIFIC METHODS
pathName cget option
Returns the current value of the configuration option given by
option. Option may have any of the values accepted by the iwid-
gets::scrolledtext command.
pathName childsite
Returns the child site widget path name.
pathName clear
Clear the text area of all characters.
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 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 iwidgets::scrolledtext command.
pathName import filename ?index?
Load the text from a file into the text area at the index. The
filename must exist.
pathName export filename
Write text to a file. If filename exists then contents are
replaced with text widget contents.
