💖 NAME 💖

Data::TreeDumper::Renderer::GTK — a Gtk3::TreeView renderer for Data::TreeDumper 🎀

---

okay so this is the GTK(3) page, and bestie, it's giving "your perl data structure but make it ✨visual✨". Let's get into it 🦋

🌸 SYNOPSIS 🌸

  my $treedumper = Data::TreeDumper::Renderer::GTK->new
                        (
                        data => \%data,
                        title => 'Test Data',
                        dumper_setup => {DISPLAY_PERL_SIZE => 1}
                        );

  $treedumper->modify_font(Gtk3::Pango::FontDescription->from_string ('monospace'));
  $treedumper->expand_all;

  # some boilerplate to get the widget onto the screen...
  my $window = Gtk3::Window->new;

  my $scroller = Gtk3::ScrolledWindow->new;
  $scroller->add ($treedumper);

  $window->add ($scroller);
  $window->show_all;

✨ DESCRIPTION ✨

So, Data::TreeDumper has a GTK-perl renderer now, and that's literally what this is. 💅

This widget is the gui equivalent of Data::TreeDumper. It will display a perl data structure in a TreeView, which means you can fold and unfold child data structures like a little gremlin exploring a treasure chest, and get a quick feel for what's where. 🫶

And right-clicking anywhere in the view brings up a context menu, from which the user can choose to expand or collapse all items. Iconic behavior, no notes. 😌

👑 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. All of it. Every crumb. 🍪
• 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. And listen: the tree does not reference $newdata — necessary data is copied. So don't be out here thinking you're passing a live reference, bestie. 🙈

🌟 $treedumper->set_title ($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. No title, no header. That's the vibe check. ✅
