## DESCRIPTION

GTK-perl renderer for **Data::TreeDumper**.

This widget is the gui equivalent of Data::TreeDumper; it will display a perl data structure in a TreeView, allowing you to fold and unfold child data structures and get a quick feel for what's where.  Right-clicking anywhere in the view brings up a context menu, from which the user can choose to expand or collapse all items.

## EXAMPLE

**gtk\_test.pl**

## METHODS

- widget = Data::TreeDumper::Renderer::GTK::TreeDumper-\>new (...)

  Create a new TreeDumper.  The optional arguments are expect to be key/val pairs.

  - \- dumper\_setup =\> hash reference

    All data is passed to Data::TreeDumper

  - \- data =\> scalar

    Equivalent to calling `"$treedumper->set_data ($scalar)"`.

  - \- title =\> string or undef

    Equivalent to calling `"$treedumper->set_title ($string)"`.

- $treedumper-\>set\_data ($newdata)

  - •

    `$newdata` (scalar)

  Fill the tree with *$newdata*, which may be any scalar.  The tree does not reference *$newdata* -- necessary data is copied.

- $treedumper-\>set\_title ($title=undef)

  - •

    `$title` (string or undef) a new title

  Set the string displayed as the column title.  The view is created with one column, and the header is visible only if there is a title set.

## EXPORT

None
