A Widget which contains a scale.
This Widget can be used to decorate composite widgets with a scale.
Create a scale with the position QwtScaleWidget::Left.
parent | Parent widget |
QwtScaleWidget::QwtScaleWidget | ( | QWidget * | parent, |
const char * | name | ||
) | [explicit] |
Create a scale with the position QwtScaleWidget::Left.
parent | Parent widget |
name | Object name |
QwtScaleWidget::QwtScaleWidget | ( | QwtScaleDraw::Alignment | align, |
QWidget * | parent = NULL |
||
) | [explicit] |
Constructor.
align | Alignment. |
parent | Parent widget |
QwtScaleWidget::~QwtScaleWidget | ( | ) | [virtual] |
Destructor.

QwtDoubleInterval QwtScaleWidget::colorBarInterval | ( | ) | const |
int QwtScaleWidget::colorBarWidth | ( | ) | const |
const QwtColorMap & QwtScaleWidget::colorMap | ( | ) | const |
Find the minimum dimension for a given length. dim is the height, length the width seen in direction of the title.
length | width for horizontal, height for vertical scales |
scaleFont | Font of the scale |
void QwtScaleWidget::draw | ( | QPainter * | p | ) | const [protected] |
draw the scale
void QwtScaleWidget::drawTitle | ( | QPainter * | painter, |
QwtScaleDraw::Alignment | align, | ||
const QRect & | rect | ||
) | const |
Rotate and paint a title according to its position into a given rectangle.

int QwtScaleWidget::endBorderDist | ( | ) | const |
void QwtScaleWidget::fontChange | ( | const QFont & | oldFont | ) | [protected, virtual] |
Notify a change of the font.
This virtual function may be overloaded by derived widgets. The default implementation resizes the scale and repaints the widget.
oldFont | Previous font |
Reimplementado de QWidget.
Calculate a hint for the border distances.
This member function calculates the distance of the scale's endpoints from the widget borders which is required for the mark labels to fit into the widget. The maximum of this distance an the minimum border distance is returned.
Get the minimum value for the distances of the scale's endpoints from the widget borders.
bool QwtScaleWidget::isColorBarEnabled | ( | ) | const |
void QwtScaleWidget::layoutScale | ( | bool | update = true | ) | [protected] |

Reimplementado de QWidget.
void QwtScaleWidget::scaleChange | ( | ) | [protected] |
Notify a change of the scale.
This virtual function can be overloaded by derived classes. The default implementation updates the geometry and repaints the widget.
void QwtScaleWidget::scaleDivChanged | ( | ) | [signal] |
Signal emitted, whenever the scale divison changes.
const QwtScaleDraw * QwtScaleWidget::scaleDraw | ( | ) | const |
scaleDraw of this scale
QwtScaleDraw * QwtScaleWidget::scaleDraw | ( | ) |
scaleDraw of this scale
void QwtScaleWidget::setAlignment | ( | QwtScaleDraw::Alignment | alignment | ) |
Specify distances of the scale's endpoints from the widget's borders. The actual borders will never be less than minimum border distance.

Change the rotation for the labels. See QwtScaleDraw::setLabelRotation().
void QwtScaleWidget::setMargin | ( | int | margin | ) |
Specify the margin to the colorBar/base line.
margin | Margin |
Set a minimum value for the distances of the scale's endpoints from the widget borders. This is useful to avoid that the scales are "jumping", when the tick labels or their positions change often.

void QwtScaleWidget::setScaleDiv | ( | QwtScaleTransformation * | transformation, |
const QwtScaleDiv & | scaleDiv | ||

Set a scale draw sd has to be created with new and will be deleted in QwtScaleWidget::~QwtScale or the next call of QwtScaleWidget::setScaleDraw.
void QwtScaleWidget::setSpacing | ( | int | spacing | ) |
Specify the distance between color bar, scale and title.
spacing | Spacing |
void QwtScaleWidget::setTitle | ( | const QString & | title | ) |
void QwtScaleWidget::setTitle | ( | const QwtText & | title | ) |
