Gtk2::E...Expander(3)

👑 Gtk2::E...Expander(3) 💖

okay bestie, so this is Gtk2::Ex::FormFactory::Expander — it lives in the User Contributed Perl Documentation section of the manual, and it's genuinely one of those lil modules that just quietly slays. come sit with me 💅

---

✨ NAME ✨

Gtk2::Ex::FormFactory::Expander — an Expander, but make it FormFactory framework energy 🦋

---

🌸 SYNOPSIS 🌸

Gtk2::Ex::FormFactory::Expander->new (
  ...
  Gtk2::Ex::FormFactory::Container attributes
  Gtk2::Ex::FormFactory::Widget attributes
);

that's the whole vibe. you pass in the Container attributes and the Widget attributes and the ... is doing its little mysterious main-character thing 🎀

---

💫 DESCRIPTION 💫

so this class implements an Expander inside a Gtk2::Ex::FormFactory framework. no cap, that's literally the job.

and here's the cute part: the expansion state isn't something you micromanage — it's controlled by the associated application object attribute, which should have a boolean value. so like, true/false, open/closed, expanded/collapsed. your app object is holding the remote control 🫶

🧚 OBJECT HIERARCHY 🧚

the family tree, and yes she's giving nobility:

Gtk2::Ex::FormFactory::Intro

Gtk2::Ex::FormFactory::Widget
+--- Gtk2::Ex::FormFactory::Container
     +--- Gtk2::Ex::FormFactory::Expander

Gtk2::Ex::FormFactory::Layout
Gtk2::Ex::FormFactory::Rules
Gtk2::Ex::FormFactory::Context
Gtk2::Ex::FormFactory::Proxy

look at her, way down at the bottom of the Widget → Container → Expander line. iconic lineage fr fr 👑

💅 ATTRIBUTES 💅

so, tea time: this module has no additional attributes over the ones it inherits from Gtk2::Ex::FormFactory::Container. she's not out here inventing new ones. but there are some special notes that absolutely apply, so don't skip this part bestie 😭

• content = ARRAYREF of Gtk2::Ex::FormFactory::Widget's [optional] — you may add only one child widget to this container. one. single. child. she is not sharing the spotlight, periodt.

🙈 POD ERRORS 🙈

not me having to report this, but the doc had some coding errors and here's the explanation:

Around line 107:

Non-ASCII character seen before =encoding in 'Jörn'. Assuming UTF-8

so the parser clocked that little ö in Jörn before it saw any =encoding declaration, and just went "eh, assuming UTF-8, we ball" 🌸 honestly? relatable. the umlaut stays. the umlaut always stays.
