QwtScaleWidget::QwtScaleWidget (QWidget *parent = NULL) [explicit]

Create a scale with the position QwtScaleWidget::Left. Parameters:

QwtScaleWidget::QwtScaleWidget (QwtScaleDraw::Alignmentalign, QWidget *parent = NULL) [explicit]

Constructor. Parameters:

QwtScaleDraw::Alignment QwtScaleWidget::alignment () const

Returns:

See also:

int QwtScaleWidget::dimForLength (intlength, const QFont &scaleFont) const

Find the minimum dimension for a given length. dim is the height, length the width seen in direction of the title. Parameters:

Returns:

void QwtScaleWidget::drawTitle (QPainter *painter, QwtScaleDraw::Alignmentalign, const QRect &rect) const

Rotate and paint a title according to its position into a given rectangle.

Parameters:

int QwtScaleWidget::endBorderDist () const

Returns:

See also:

void QwtScaleWidget::getBorderDistHint (int &start, int &end) const

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.

Warning:

See also:

void QwtScaleWidget::getMinBorderDist (int &start, int &end) const

Get the minimum value for the distances of the scale's endpoints from the widget borders.

See also:

int QwtScaleWidget::margin () const

Returns:

See also:

QSize QwtScaleWidget::minimumSizeHint () const [virtual]

Returns:

int QwtScaleWidget::penWidth () const

Returns:

See also:

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.

const QwtScaleDraw * QwtScaleWidget::scaleDraw () const

scaleDraw of this scale

See also:

QwtScaleDraw * QwtScaleWidget::scaleDraw ()

scaleDraw of this scale

See also:

void QwtScaleWidget::setAlignment (QwtScaleDraw::Alignmentalignment)

Change the alignment

Parameters:

See also:

void QwtScaleWidget::setBorderDist (intdist1, intdist2)

Specify distances of the scale's endpoints from the widget's borders. The actual borders will never be less than minimum border distance.

Parameters:

See also:

void QwtScaleWidget::setLabelAlignment (Qt::Alignmentalignment)

Change the alignment for the labels. See also:

void QwtScaleWidget::setLabelRotation (doublerotation)

Change the rotation for the labels. See QwtScaleDraw::setLabelRotation(). Parameters:

See also:

void QwtScaleWidget::setMargin (intmargin)

Specify the margin to the colorBar/base line. Parameters:

See also:

void QwtScaleWidget::setMinBorderDist (intstart, intend)

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.

Parameters:

See also:

void QwtScaleWidget::setPenWidth (intwidth)

Specify the width of the scale pen. Parameters:

See also:

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

Assign a scale division. The scale division determines where to set the tick marks.

Parameters:

See also:

void QwtScaleWidget::setScaleDraw (QwtScaleDraw *sd)

Set a scale draw sd has to be created with new and will be deleted in ~QwtScaleWidget() or the next call of setScaleDraw().

Parameters:

See also:

void QwtScaleWidget::setSpacing (intspacing)

Specify the distance between color bar, scale and title. Parameters:

See also:

void QwtScaleWidget::setTitle (const QString &title)

Give title new text contents

Parameters:

See also:

void QwtScaleWidget::setTitle (const QwtText &title)

Give title new text contents

Parameters:

See also:

Warning:

QSize QwtScaleWidget::sizeHint () const [virtual]

Returns:

int QwtScaleWidget::spacing () const

Returns:

See also:

int QwtScaleWidget::startBorderDist () const

Returns:

See also:

QwtText QwtScaleWidget::title () const

Returns:

See also:

int QwtScaleWidget::titleHeightForWidth (intwidth) const

Find the height of the title for a given width. Parameters:

Returns:
