Detailed Description

Specialized shape representing a rectangle.

This class inherits all the functions of gf::Transformable (position, rotation, scale, bounds, ...) as well as the functions of gf::Shape (outline, color, texture, ...).

Usage example:

rectangle.setSize({ 100.0f, 50.0f });
rectangle.setOutlineThickness(5);
rectangle.setPosition({ 10.0f, 20.0f });
...
window.draw(rectangle);

Constructor & Destructor Documentation

◆ RectangleShape() [1/2]

gf::RectangleShape::RectangleShape ( Vector2f  size = Vector2f{ 0.0f, 0.0f })

Default constructor.

Parameters
sizeSize of the rectangle

◆ RectangleShape() [2/2]

gf::RectangleShape::RectangleShape ( const RectF rect)
explicit

Constructor with a rectangle.

The shape takes the size of the rectangle and the position of the rectangle.

Parameters
rectA rectangle with a size and a position

Member Function Documentation

◆ getPoint()

virtual Vector2f gf::RectangleShape::getPoint ( std::size_t  index) const
overridevirtual

Get a point of the shape.

The returned point is in local coordinates, that is, the shape's transforms (position, rotation, scale) are not taken into account.

The result is undefined if index is out of the valid range.

Parameters
indexIndex of the point to get, in range \( [0, n-1] \) where \( n \) is the number of points of the shape.
Returns
index-th point of the shape
See also
getPointCount()

Implements gf::Shape.

◆ getPointCount()

virtual std::size_t gf::RectangleShape::getPointCount ( ) const
overridevirtual

Get the total number of points of the shape.

Returns
Number of points of the shape
See also
getPoint()

Implements gf::Shape.

◆ getSize()

Vector2f gf::RectangleShape::getSize ( ) const
inline

Get the size of the rectangle.

Returns
Size of the rectangle
See also
setSize()

◆ setSize()

void gf::RectangleShape::setSize ( Vector2f  size)

Set the size of the rectangle.

Parameters
sizeNew size of the rectangle
