.IP "Name: \fB\-showcommand\fR" 4
.IX Item "Name: -showcommand"
Specifies a callback for selecting a Pod module (Button\-1 binding).
.IP "Name: \fB\-showcommand2\fR" 4
.IX Item "Name: -showcommand2"
Specifies a callback for selecting a Pod module in a different window
(Button\-2 binding).
.IP "Name: \fB\-usecache\fR" 4
.IX Item "Name: -usecache"
True, if a cache of Pod modules should be created and used. The
default is true.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBTk::Pod::Tree\fR widget shows all available Perl Pod documentation
in a tree.
.SH "WIDGET METHODS"
.IX Header "WIDGET METHODS"
.IP "\fI\f(CI$tree\fI\fR\->\fBFill\fR(?\fI\-nocache => 1\fR?, ?\fI\-forked => 0|1\fR?, ?\fI\-fillcb => ...\fR?)" 4
.IX Item "$tree->Fill(?-nocache => 1?, ?-forked => 0|1?, ?-fillcb => ...?)"
Find Pod modules and fill the tree widget. If \fI\-nocache\fR is
specified, then no cache will be used for loading.
.Sp
A cache of Pod modules is written unless the \fB\-usecache\fR
configuration option of the widget is set to false.
.Sp
If \f(CW\*(C`\-forked\*(C'\fR is specified, then searching for Pods is done in the
background, if possible. Note that the default is currently
unspecified.
.Sp
A callback may be specified with the \f(CW\*(C`\-fillcb\*(C'\fR option and will be
called after the tree is filled.
.IP "\fI\f(CI$tree\fI\fR\->\fBSeePath\fR($path)" 4
.IX Item "$tree->SeePath($path)"
Move the anchor/selection and view to the given \f(CW$path\fR and open
subtrees to make the \f(CW$path\fR visible, if necessary.
