QCanvasPolygon(3qt)

📦 version 3.3.8b, in fedora 43, fedora 44

💖 QCanvasPolygon — bestie edition 💖

okay so this is the QCanvasPolygon(3qt) manual page, and we're gonna make it make sense. it's giving Qt 3, it's giving canvas graphics, it's giving polygon realness. let's go 🦋

✨ NAME ✨

QCanvasPolygon — a whole polygon, but make it live on a QCanvas 💅

🌸 SYNOPSIS 🌸

Inherits QCanvasPolygonalItem.

Inherited by QCanvasSpline.

👑 DESCRIPTION 👑

The QCanvasPolygon class provides a polygon on a QCanvas. no cap, that's the whole job and it does it beautifully.

It paints a polygon with a QBrush. the polygon's points can be set in the constructor, or set or changed later using setPoints(). wanna get them back? use points(). wanna get them relative to the canvas's origin? that's areaPoints()'s moment. ✨

The polygon can be drawn on a painter with drawShape(). iconic.

Like any other canvas item, polygons can be moved with QCanvasItem::move() and QCanvasItem::moveBy(), or by setting coordinates with QCanvasItem::setX(), QCanvasItem::setY() and QCanvasItem::setZ(). move it around bestie, it's your polygon 💃

⚠️ Note: QCanvasPolygon does not use the pen. like. at all. the pen is simply not invited to this party 🙈

💀 MEMBER FUNCTION DOCUMENTATION 💀

QCanvasPolygon::QCanvasPolygon ( QCanvas * canvas )

Constructs a point-less polygon on the canvas canvas. literally zero points, empty, a blank canvas of a canvas item 😭

You should call setPoints() before using it further. fr fr. do it. it's nothing without points.

QCanvasPolygon::~QCanvasPolygon ()

Destroys the polygon. bye bestie 👋💜

QPointArray QCanvasPolygon::areaPoints () const [virtual]

Returns the vertices of the polygon translated by the polygon's current x(), y() position — i.e. relative to the canvas's origin. so it's the "where is it actually" version of the points. the main character coordinates 🫶

See also setPoints() and points().

Reimplemented from QCanvasPolygonalItem.

void QCanvasPolygon::drawShape ( QPainter & p ) [virtual protected]

Draws the polygon using the painter p. slay 💅

⚠️ Note that QCanvasPolygon does not support an outline — the pen is always NoPen. so don't come looking for an outline, it's not there, it never was 🌸

Reimplemented from QCanvasPolygonalItem.

QPointArray QCanvasPolygon::points () const

Returns the vertices of the polygon, not translated by the position. so like, the raw local points, before any moving-around happens. the unedited version, if you will 💖

See also setPoints() and areaPoints().

int QCanvasPolygon::rtti () const [virtual]

Returns 4 (QCanvasItem::Rtti_Polygon). that's its little ID badge, its vibe check number, its ✨ identity ✨

See also QCanvasItem::rtti().

Reimplemented from QCanvasPolygonalItem.

Reimplemented in QCanvasSpline.

void QCanvasPolygon::setPoints ( QPointArray pa )

Sets the points of the polygon to be pa. these points will have their x and y coordinates automatically translated by x(), y() as the polygon is moved. so you set them once, and the polygon handles the moving math itself. lowkey so convenient 🦋

this little masterpiece dropped on 2 February 2007, brought to you by Trolltech AS, and it's riding with Qt 3.3.8 — ok love u bye 💜🧚🍓
