int QwtScaleWidget::endBorderDist ( ) const

Devuelve:: end border distance

Ver también:: QwtScaleWidget::setBorderDist

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.

Parámetros:

oldFont Previous font

Reimplementado de QWidget.

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.

Atención:

The minimum border distance depends on the font.

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

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