Detailed Description

The QLine class provides a two-dimensional vector using integer precision.

A QLine describes a finite length line (or a line segment) on a two-dimensional surface. The start and end points of the line are specified using integer point accuracy for coordinates. Use the QLineF constructor to retrieve a floating point copy.

The positions of the line's start and end points can be retrieved using the p1(), x1(), y1(), p2(), x2(), and y2() functions. The dx() and dy() functions return the horizontal and vertical components of the line. Use isNull() to determine whether the QLine represents a valid line or a null line.

Finally, the line can be translated a given offset using the translate() function.

See also QLineF, QPolygon, and QRect.

Member Function Documentation

virtual void QtCore.QLine.CreateProxy ( )

virtual

new void QtCore.QLine.Dispose

(

)

new int QtCore.QLine.Dx

(

)

Returns the horizontal component of the line's vector.

See also dy().

new int QtCore.QLine.Dy

(

)

Returns the vertical component of the line's vector.

See also dx().

override bool QtCore.QLine.Equals

(

object

o

)

override int QtCore.QLine.GetHashCode

(

)

new bool QtCore.QLine.IsNull

(

)

Returns true if the line is not set up with valid start and end point; otherwise returns false.

static bool QtCore.QLine.operator!= ( QLine  arg1, QLine  arg2  )

static

Returns true if the given line is not the same as this line.

A line is different from another line if any of their start or end points differ, or the internal order of the points is different.

static bool QtCore.QLine.operator== ( QLine  arg1, QLine  arg2  )

static

Returns true if the given line is the same as this line.

A line is identical to another line if the start and end points are identical, and the internal order of the points is the same.

new void QtCore.QLine.SetLine	(	int	x1,
		int	y1,
		int	x2,
		int	y2
	)

Sets this line to the start in x1, y1 and end in x2, y2.

This function was introduced in Qt 4.4.

See also setP1(), setP2(), p1(), and p2().

new void QtCore.QLine.SetPoints	(	QPoint	p1,
		QPoint	p2
	)

Sets the start point of this line to p1 and the end point of this line to p2.

This function was introduced in Qt 4.4.

See also setP1(), setP2(), p1(), and p2().

new void QtCore.QLine.Translate

(

QPoint

p

)

Translates this line by the given offset.

new void QtCore.QLine.Translate	(	int	dx,
		int	dy
	)

This is an overloaded function.

Translates this line the distance specified by dx and dy.

new QLine QtCore.QLine.Translated

(

QPoint

p

)

Returns this line translated by the given offset.

This function was introduced in Qt 4.4.

new QLine QtCore.QLine.Translated	(	int	dx,
		int	dy
	)

This is an overloaded function.

Returns this line translated the distance specified by dx and dy.

This function was introduced in Qt 4.4.

new int QtCore.QLine.X1

(

)

Returns the x-coordinate of the line's start point.

See also p1().

new int QtCore.QLine.X2

(

)

Returns the x-coordinate of the line's end point.

See also p2().

new int QtCore.QLine.Y1

(

)

Returns the y-coordinate of the line's start point.

See also p1().

new int QtCore.QLine.Y2

(

)

Returns the y-coordinate of the line's end point.

See also p2().
