Detailed DescriptionThe QGeoMapTextObject class is a QGeoMapObject used to draw text on a map. The text is drawn at a given coordinate on the map. The text object is drawn such that the rendered size of the text object is independent of the zoom level of the map. Property Documentation

| Qt::Alignment | alignment () const |
| void | setAlignment ( Qt::Alignment alignment ) |
Notifier signal:
| void | alignmentChanged ( Qt::Alignment alignment ) |
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 the glyphs of the text.
The outline around the perimeter of the glyphs is drawn using the QGeoMapTextObject::pen property.
Access functions:
| QBrush | brush () const |
| void | setBrush ( const QBrush & brush ) |
Notifier signal:
| void | brushChanged ( const QBrush & brush ) |
coordinate : QGeoCoordinate
This property holds this property holds the coordinate at which this text object will be rendered.
The default value of this property is an invalid coordinate. While the value of this property is invalid the text object will not be displayed.
If QGeoMapTextObject::offset and QGeoMapTextObject::alignment are not set the text will be drawn so that it is centered both horizontally and vertically around the position of QGeoMapTextObject::coordinate on the screen.
Access functions:
| QGeoCoordinate | coordinate () const |
| void | setCoordinate ( const QGeoCoordinate & coordinate ) |
Notifier signal:
| void | coordinateChanged ( const QGeoCoordinate & coordinate ) |
font : QFont
This property holds this property holds the font that will be used to render the text for this text object.
The default value of this property is the application's default font.
It is not necessary to account for the zoom level of the map, since text objects are scaled such that they appear to be independent of the zoom level.
Access functions:
| QFont | font () const |
| void | setFont ( const QFont & font ) |
Notifier signal:
| void | fontChanged ( const QFont & font ) |
offset : QPoint
This property holds this property holds the offset in pixels from the screen position of QGeoMapTextObject::coordinate at which the text will be rendered when drawing this text object.
The default value of this property is QPoint(0,0).
Access functions:
| QPoint | offset () const |
| void | setOffset ( const QPoint & offset ) |
Notifier signal:
| void | offsetChanged ( const QPoint & offset ) |
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 text. The text itself is filled using the QGeoMapTextObject::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 ) |
text : QString
This property holds this property holds the text that will be displayed by this text object.
The default value of this property is an empty string.
Access functions:
| QString | text () const |
| void | setText ( const QString & text ) |
Notifier signal:
| void | textChanged ( const QString & text ) |
Member Function Documentation
QGeoMapTextObject::QGeoMapTextObject ()
Constructs a new text object.
QGeoMapTextObject::QGeoMapTextObject ( const QGeoCoordinate & coordinate, const QString & text = QString(), const QFont & font = QFont(), const QPoint & offset = QPoint(), Qt::Alignment alignment = Qt::AlignCenter )
Constructs a new text object which will display the text text with font font at the coordinate coordinate on the map.
The text will be displayed at an on-screen offset from the coordinate of offset pixels, and will be aligned according to alignment.
QGeoMapTextObject::~QGeoMapTextObject ()
Destroys this text object.
void QGeoMapTextObject::alignmentChanged ( Qt::Alignment alignment ) [signal]
This signal is emitted when the alignment of this text object has changed.
The new value is alignment.
void QGeoMapTextObject::brushChanged ( const QBrush & brush ) [signal]
This signal is emitted when the brush used to fill the inside of the letters for this text object has changed.
The new value is brush.
void QGeoMapTextObject::coordinateChanged ( const QGeoCoordinate & coordinate ) [signal]
This signal is emitted when the coordinate at which this text object will be drawn has changed.
The new value is coordinate.
void QGeoMapTextObject::fontChanged ( const QFont & font ) [signal]
This signal is emitted when the font use to draw this text object has changed.
The new value is font.
void QGeoMapTextObject::offsetChanged ( const QPoint & offset ) [signal]
This signal is emitted when the on screen offset from the coordinate at which this text object will be drawn has changed.
The new value is offset.
void QGeoMapTextObject::penChanged ( const QPen & pen ) [signal]
This signal is emitted when the pen used to draw the outline of the letters for this text object has changed.
The new value is pen.
void QGeoMapTextObject::textChanged ( const QString & text ) [signal]
This signal is emitted when the text to be drawn by this text object has changed.
The new value is text.
QGeoMapObject::Type QGeoMapTextObject::type () const [virtual]
Reimplemented from QGeoMapObject::type().
