.IX Title "SCROLLED 1"
.TH SCROLLED 1 "2000-12-30" "perl v5.8.0" "User Contributed Perl Documentation"
.SH "NAME"
Tk::Scrolled \- Create a widget with attached scrollbar(s)
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\ \fI$whatever\fR = \fI$parent\fR\->\fBScrolled\fR(\fIWhatever\fR ?,\fB\-scrollbars\fR=>\fIwhere\fR? ?,...?);
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
To stop a flood of \fBScrlWhatever\fR widgets Perl/Tk introcuded the special
constructor \fBScrolled\fR.  \fBScrolled\fR creates a widget of the given Class
\&\fIWhatever\fR with attached scrollbar(s).
.SH "OPTIONS"
.IX Header "OPTIONS"
All options beside \fB\-scrollbars\fR explained below are passed to
the \fIWhatever\fR widget constructor.
.IP "\-scrollbars" 4
.IX Item "-scrollbars"
Expects as argument the position where the scrollbars should be
created:  \fBw\fR, \fBe\fR or \fBn\fR, \fBs\fR or a combination of
them.  If the one or both positions are prefixed with \fBo\fR the
scrollbar will only show up if there is a 'real' need to scroll.
.SH "ADVERTISED SUBWIDGETS"
.IX Header "ADVERTISED SUBWIDGETS"
See \*(L"Subwidget\*(R" in Tk::mega how to use advertised widgets.
.IP "scrolled" 4
.IX Item "scrolled"
the scrolled widget
.IP "\fIwidget\fR" 4
.IX Item "widget"
same as \fBscrolled\fR above.  \fIwidget\fR is the kind of widget passed
to scrolled as first argument in all lowercase.
.IP "xscrollbar" 4
.IX Item "xscrollbar"
the \fBScrollbar\fR widget used for horizontal scrolling (if it exists)
.IP "yscrollbar" 4
.IX Item "yscrollbar"
the \fBScrollbar\fR widget used for vertical scrolling (if it exists)
.IP "corner" 4
.IX Item "corner"
a frame in the corner between the vertical and horizontal scrolbar
.SH "BUGS"
.IX Header "BUGS"
If a widget does not support \fI\-{x,y}scrollcommand\fR options,
\&\fBScrolled\fR does not complain if the specified widget class does
not support them.  E.g.,
.PP
\&\ \fI$parent\fR\->\fBScrolled\fR(\fB'Button'\fR, ...)
.PP
One does not get an error message or warning when one tries to
configure scrollbars after the widget construction:
.PP
\&\ \fI$ascrolled\fR\->\fBconfigure\fR(\fB\-scrollbars\fR => \fB'e'\fR);
.SH "SEE ALSO"
.IX Header "SEE ALSO"

.SH "KEYWORDS"
.IX Header "KEYWORDS"
