voidQwtSlider::setBorderWidth(intwidth)
Change the slider's border width. The border width is used for drawing the slider handle and the trough.
Parameters:width Border width
Seealso:borderWidth()voidQwtSlider::setGroove(boolon)
En/Disable the groove
The slider can be cutomized by showing a groove for the handle.
Parameters:on When true, the groove is visible
Seealso:hasGroove(), setThrough()
voidQwtSlider::setHandleSize(constQSize&size)
Set the slider's handle size. When the size is empty the slider handle will be painted with a default
size depending on its orientation() and backgroundStyle().
Parameters:size New size
Seealso:handleSize()voidQwtSlider::setOrientation(Qt::Orientationorientation)
Set the orientation.
Parameters:orientation Allowed values are Qt::Horizontal and Qt::Vertical.
Seealso:orientation(), scalePosition()voidQwtSlider::setScaleDraw(QwtScaleDraw*scaleDraw)
Set a scale draw. For changing the labels of the scales, it is necessary to derive from QwtScaleDraw and
overload QwtScaleDraw::label().
Parameters:scaleDraw ScaleDraw object, that has to be created with new and will be deleted in ~QwtSlider() or
the next call of setScaleDraw().

scaleDraw()
voidQwtSlider::setScalePosition(ScalePositionscalePosition)
Change the position of the scale.
Parameters:scalePosition Position of the scale.
Seealso:ScalePosition, scalePosition()voidQwtSlider::setSpacing(intspacing)
Change the spacing between trough and scale. A spacing of 0 means, that the backbone of the scale is
covered by the trough.
The default setting is 4 pixels.
Parameters:spacing Number of pixels
