Detailed Description

The QRegion class specifies a clip region for a painter.

\inmodule QtGui

QRegion is used with QPainter::setClipRegion() to limit the paint area to what needs to be painted. There is also a QWidget::repaint() function that takes a QRegion parameter. QRegion is the best tool for minimizing the amount of screen area to be updated by a repaint.

This class is not suitable for constructing shapes for rendering, especially as outlines. Use QPainterPath to create paths and shapes for use with QPainter.

QRegion is an \l{implicitly shared} class.

Constructor & Destructor Documentation

◆ QRegion() [1/7]

QRegion::QRegion ( )

Constructs an empty region.

See also: isEmpty()

Definition at line 3793 of file qregion.cpp.

◆ QRegion() [2/7]

QRegion::QRegion	(	int	x,
		int	y,
		int	w,
		int	h,
		RegionType	t = Rectangle )

Constructs a rectangular or elliptic region.

If t is Rectangle, the region is the filled rectangle (x, y, w, h). If t is Ellipse, the region is the filled ellipse with center at (x + w / 2, y + h / 2) and size (w ,h).

Definition at line 160 of file qregion.cpp.

◆ QRegion() [3/7]

QRegion::QRegion	(	const QRect &	r,
		RegionType	t = Rectangle )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.Create a region based on the rectangle r with region type t.

If the rectangle is invalid a null region will be created.

See also: QRegion::RegionType

Definition at line 3798 of file qregion.cpp.

◆ QRegion() [4/7]

QRegion::QRegion	(	const QPolygon &	a,
		Qt::FillRule	fillRule = Qt::OddEvenFill )

Constructs a polygon region from the point array a with the fill rule specified by fillRule.

If fillRule is \l{Qt::WindingFill}, the polygon region is defined using the winding algorithm; if it is \l{Qt::OddEvenFill}, the odd-even fill algorithm is used.

Warning: This constructor can be used to create complex regions that will slow down painting when used.

Definition at line 3815 of file qregion.cpp.

◆ QRegion() [5/7]

QRegion::QRegion ( const QRegion & region )

Constructs a new region which is equal to region r.

Definition at line 3831 of file qregion.cpp.

◆ QRegion() [6/7]

QRegion::QRegion ( QRegion && other )

inlinenoexcept

Since: 5.7

See also: isNull()

Definition at line 36 of file qregion.h.

Constructs a region from the bitmap bm.

The resulting region consists of the pixels in bitmap bm that are Qt::color1, as if each pixel was a 1 by 1 rectangle.

This constructor may create complex regions that will slow down painting when used. Note that drawing masked pixmaps can be done much faster using QPixmap::setMask().
