💖 Goo::Canvas::ItemSimple — the manual, but make it cute 💖

okay bestie, welcome to the User Contributed Perl Documentation page for Goo::Canvas::ItemSimple ✨ this is the whole thing, every flag, every enum, every lil' default, nothing skipped, periodt.

🌸 NAME 🌸

Goo::Canvas::ItemSimple — it's a wrapper for GooCanvasItemSimple. that's it, that's the vibe. it wraps the thing so you don't have to touch the thing directly 🫶

🦋 HIERARCHY 🦋

the family tree, and it's giving nepo baby:

Glib::Object
+----Goo::Canvas::ItemSimple

🎀 INTERFACES 🎀

it also does this interface, so it's got range:

Goo::Canvas::Item

✨ METHODS ✨

here's every method, no gatekeeping 💅

  • $item->goo_canvas_item_simple_changed ($recompute_bounds) — tells the item "hey, something changed, pls update". takes:
    • $recompute_bounds — a boolean. yes or no, true or false, iconic or not.
  • boolean = $item->goo_canvas_item_simple_check_in_path ($x, $y, $cr, $pointer_events) — checks whether a point is inside the path. returns a boolean. args:
    • $x — a double
    • $y — a double
    • $cr — a cairo_t
    • $pointer_events — a Goo::Canvas::PointerEvents
  • $item->goo_canvas_item_simple_check_style — checks the style. no args, no notes, just vibes.
  • GooCanvasBounds = $item->goo_canvas_item_simple_get_path_bounds ($cr) — hands you the path bounds back as a GooCanvasBounds. args:
    • $cr — a cairo_t
  • $item->goo_canvas_item_simple_paint_path ($cr) — paints the path. args:
    • $cr — a cairo_t
  • $item->goo_canvas_item_simple_set_model ($model) — sets the model. args:
    • $model — a Goo::Canvas::ItemModel
  • GooCanvasBounds = $item->goo_canvas_item_simple_user_bounds_to_device ($cr) — converts user bounds → device bounds, returns GooCanvasBounds. args:
    • $cr — a cairo_t
  • GooCanvasBounds = $item->goo_canvas_item_simple_user_bounds_to_parent ($cr) — converts user bounds → parent bounds, returns GooCanvasBounds. args:
    • $cr — a cairo_t

💜 PROPERTIES 💜

the full lineup, all 21 of them, no skips. format is 'name' (type : default : readable / writable) and then what it actually does 🍓

  • 'antialias' (Goo::Cairo::Antialias : default "gray" : readable / writable) — the antialiasing mode to use.
  • 'clip-fill-rule' (Goo::Cairo::FillRule : default "winding" : readable / writable) — the fill rule that decides which parts of the item get clipped.
  • 'clip-path' (string : default undef : writable) — the sequence of path commands that specify the clip path.
  • 'fill-color' (string : default undef : writable) — the color used to paint the inside of the item. wanna turn painting OFF? set the 'fill-pattern' property to NULL.
  • 'fill-color-rgba' (Glib::UInt : default 0 : readable / writable) — same deal, the color for the item's interior, but given as a 32-bit integer value. and again: to disable painting, set 'fill-pattern' to NULL.
  • 'fill-pattern' (Goo::Cairo::Pattern : default undef : readable / writable) — the pattern used to paint the interior, or NULL to disable painting entirely.
  • 'fill-pixbuf' (Gtk2::Gdk::Pixbuf : default undef : writable) — the pixbuf used to paint the interior. yep, you guessed it: set 'fill-pattern' to NULL to disable painting.
  • 'fill-rule' (Goo::Cairo::FillRule : default "winding" : readable / writable) — the fill rule that decides which parts of the item get filled.
  • 'font' (string : default undef : readable / writable) — the base font used for the text.
  • 'font-desc' (Pango::FontDescription : default undef : readable / writable) — the attributes specifying which font to use.
  • 'hint-metrics' (GooCairoHintMetrics : default "off" : readable / writable) — the hinting used for font metrics.
  • 'line-cap' (Goo::Cairo::LineCap : default "butt" : readable / writable) — the line cap style to use.
  • 'line-dash' (Goo::Canvas::LineDash : default undef : readable / writable) — the dash pattern to use.
  • 'line-join' (Goo::Cairo::LineJoin : default "miter" : readable / writable) — the line join style to use.
  • 'line-join-miter-limit' (double : default 10 : readable / writable) — the smallest angle to use with miter joins, in degrees. below this limit it switches to bevel joins.
  • 'line-width' (double : default 2 : readable / writable) — the line width for the item's perimeter.
  • 'operator' (Goo::Cairo::Operator : default "over" : readable / writable) — the compositing operator to use.
  • 'stroke-color' (string : default undef : writable) — the color for the item's perimeter. to disable painting, set the 'stroke-pattern' property to NULL.
  • 'stroke-color-rgba' (Glib::UInt : default 0 : readable / writable) — the perimeter color, but as a 32-bit integer value. disable painting by setting 'stroke-pattern' to NULL.
  • 'stroke-pattern' (Goo::Cairo::Pattern : default undef : readable / writable) — the pattern used to paint the item's perimeter, or NULL to disable painting.
  • 'stroke-pixbuf' (Gtk2::Gdk::Pixbuf : default undef : writable) — the pixbuf used to draw the item's perimeter. disable painting by setting 'stroke-pattern' to NULL.
