Detailed DescriptionThe QGeoMapRectangleObject class is a QGeoMapObject used to draw a rectangular region on a map. The rectangle is specified by either a valid QGeoBoundingBox instance or a pair of valid QGeoCoordinate instances which represent the top left and bottom right coordinates of the rectangle respectively.

| QGeoCoordinate | bottomRight () const |
| void | setBottomRight ( const QGeoCoordinate & bottomRight ) |
Notifier signal:
| void | bottomRightChanged ( const QGeoCoordinate & bottomRight ) |
brush : QBrush
This property holds this property holds the brush that will be used to draw this object.
The brush is used to fill in rectangle.
The outline around the perimeter of the rectangle is drawn using the QGeoMapRectangleObject::pen property.
Access functions:
| QBrush | brush () const |
| void | setBrush ( const QBrush & brush ) |
Notifier signal:
| void | brushChanged ( const QBrush & brush ) |
pen : QPen
This property holds this property holds the pen that will be used to draw this object.
The pen is used to draw an outline around the rectangle. The rectangle is filled using the QGeoMapRectangleObject::brush property.
The pen will be treated as a cosmetic pen, which means that the width of the pen will be independent of the zoom level of the map.
Access functions:
| QPen | pen () const |
| void | setPen ( const QPen & pen ) |
Notifier signal:
| void | penChanged ( const QPen & pen ) |
topLeft : QGeoCoordinate
This property holds this property holds the top left coordinate of the rectangle to be drawn by this rectangle object.
The default value of this property is an invalid coordinate. While the value of this property is invalid the rectangle object will not be displayed.
Access functions:
| QGeoCoordinate | topLeft () const |
| void | setTopLeft ( const QGeoCoordinate & topLeft ) |
Notifier signal:
| void | topLeftChanged ( const QGeoCoordinate & topLeft ) |
Member Function Documentation
QGeoMapRectangleObject::QGeoMapRectangleObject ()
Constructs a new rectangle object.
QGeoMapRectangleObject::QGeoMapRectangleObject ( const QGeoBoundingBox & boundingBox )
Constructs a new rectangle object based on the bounding box boundingBox.
QGeoMapRectangleObject::QGeoMapRectangleObject ( const QGeoCoordinate & topLeft, const QGeoCoordinate & bottomRight )
Constructs a new rectangle object with the top left coordinate at topLeft and the bottom right coordinate at bottomRight.
QGeoMapRectangleObject::~QGeoMapRectangleObject ()
Destroys this rectangle object.
void QGeoMapRectangleObject::bottomRightChanged ( const QGeoCoordinate & bottomRight ) [signal]
This signal is emitted when the bottom right coordinate of this rectangle object has changed.
The new value is bottomRight.
QGeoBoundingBox QGeoMapRectangleObject::bounds () const
Returns a QGeoBoundingBox instance which corresponds to the rectangle that will be drawn by this object.
This is equivalent to
QGeoMapRectangleObject *object;
// setup object
QGeoBoundingBox(object->topLeft(), object->bottomRight());
See also setBounds().
void QGeoMapRectangleObject::brushChanged ( const QBrush & brush ) [signal]
This signal is emitted when the brush used to fill in the interior of this rectangle object has changed.
The new value is brush.
void QGeoMapRectangleObject::penChanged ( const QPen & pen ) [signal]
This signal is emitted when the pen used to draw the perimeter of this rectangle object has changed.
The new value is pen.
void QGeoMapRectangleObject::setBounds ( const QGeoBoundingBox & bounds )
Sets the rectangle that will be drawn by this object to bounds.
This is equivalent to
QGeoMapRectangleObject *object;
// setup object
object->setTopLeft(bounds.topLeft());
object->setBottomRight(bounds.bottomRight());
See also bounds().
void QGeoMapRectangleObject::topLeftChanged ( const QGeoCoordinate & topLeft ) [signal]
This signal is emitted when the top left coordinate of this rectangle object has changed.
The new value is topLeft.
QGeoMapObject::Type QGeoMapRectangleObject::type () const [virtual]
Reimplemented from QGeoMapObject::type().
