💖 Gtk2::Curve — bestie, it's a curve widget

okay so this is Gtk2::Curve, and it's literally just the Perl wrapper for GtkCurve. that's it, that's the whole name section, we move. ✨

(also hi, this page lives in the User Contributed Perl Documentation section of the manual, section 3, and yes it's the Gtk2::Curve(3) page you were looking for 🫶)

🌸 HIERARCHY 🌸

this is the family tree, the ancestry, the lineage, and you gotta respect it:

Glib::Object
+----Glib::InitiallyUnowned
     +----Gtk2::Object
          +----Gtk2::Widget
               +----Gtk2::DrawingArea
                    +----Gtk2::Curve

so Gtk2::Curve is a Gtk2::DrawingArea is a Gtk2::Widget is a Gtk2::Object is a Glib::InitiallyUnowned is a Glib::Object. generational wealth fr fr. 👑

🦋 INTERFACES 🦋

it also rocks these interfaces, like accessories but for objects:

  • Glib::Object::_Unregistered::AtkImplementorIface
  • Gtk2::Buildable

✨ METHODS ✨

🎀 widget = Gtk2::Curve->new

make a brand new curve. that's the whole vibe. slay.

💅 $curve->set_curve_type ($type)

sets what kind of curve this is.

  • $type (a Gtk2::CurveType)

🌈 $curve->set_gamma ($gamma)

sets the gamma, bestie.

  • $gamma (double)

🍓 $curve->set_range ($min_x, $max_x, $min_y, $max_y)

the range. the whole range. all four of them.

  • $min_x (double)
  • $max_x (double)
  • $min_y (double)
  • $max_y (double)

🧚 $curve->reset

boom. reset. back to square one, no questions asked.

⭐ list = $curve->get_vector ($veclen=32)

returns a list of real numbers — that's the curve's vector, the actual data of the whole thing.

  • $veclen (integer) — and heads up, it defaults to 32

💜 $curve->set_vector (...)

sets the vector. so like, the points of the curve.

  • ... (list) of float's, the points of the curve

👑 PROPERTIES 👑

'curve-type' (Gtk2::CurveType : default "spline" : readable / writable / private / static-nick / static-blurb)

Is this curve linear, spline interpolated, or free-form

'max-x' (float : default 1 : readable / writable / private / static-nick / static-blurb)

Maximum possible X value

'max-y' (float : default 1 : readable / writable / private / static-nick / static-blurb)

Maximum possible value for Y

'min-x' (float : default 0 : readable / writable / private / static-nick / static-blurb)

Minimum possible value for X

'min-y' (float : default 0 : readable / writable / private / static-nick / static-blurb)

Minimum possible value for Y

🔥 SIGNALS 🔥

  • curve-type-changed (Gtk2::Curve)

that's the one. it fires, you handle it, iconic behavior.

💀 ENUMS AND FLAGS 💀

enum Gtk2::CurveType

the three moods a curve can be in:

  • 'linear' / GTK_CURVE_TYPE_LINEAR
  • 'spline' / GTK_CURVE_TYPE_SPLINE
  • 'free' / GTK_CURVE_TYPE_FREE
