double | y, | |||
double | width, | |||
double | height | |||
) |
Construct a rectangle.
Constructs a rectangle with top left point (x, y) and size width x height.
Construct a rectangle.
Constructs a rectangle from the two points topLeft and bottomRight.
bool Wt::WRectF::isNull | ( | ) | const |
void Wt::WRectF::setX | ( | double | x | ) |
Changes the X-position of the left side.
The right side of the rectangle does not move, and as a result, the rectangle may be resized.
void Wt::WRectF::setY | ( | double | y | ) |
Changes the Y-position of the top side.
The bottom side of the rectangle does not move, and as a result, the rectangle may be resized.
void Wt::WRectF::setWidth | ( | double | width | ) | [inline] |
Changes the width.
The right side of the rectangle may move, but does not change the X position of the left side.
void Wt::WRectF::setHeight | ( | double | height | ) | [inline] |
Changes the Y-position of the top side.
The bottom side of the rectangle may move, but does not change the Y position of the top side.
