public class QStyleOptionSlider
extends QStyleOptionComplex
implements java.lang.Cloneable

The QStyleOptionSlider class is used to describe the parameters needed for drawing a slider. QStyleOptionSlider contains all the information that QStyle functions need to draw QSlider and QScrollBar.

For performance reasons, the access to the member variables is direct (i.e., using the . or -> operator). This low-level feel makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.

For an example demonstrating how style options can be used, see the Styles example.

Constructor Detail

QStyleOptionSlider

public QStyleOptionSlider()
Constructs a QStyleOptionSlider, initializing the members variables to their default values.


QStyleOptionSlider

public QStyleOptionSlider(QStyleOptionSlider other)
Constructs a copy of the other style option.

Method Detail

setTickInterval

public final void setTickInterval(int tickInterval)
This variable holds the interval that should be drawn between tick marks. The default value is 0.


tickInterval

public final int tickInterval()
This variable holds the interval that should be drawn between tick marks. The default value is 0.


setMinimum

public final void setMinimum(int minimum)
This variable holds the minimum value for the slider. The default value is 0.


minimum

public final int minimum()
This variable holds the minimum value for the slider. The default value is 0.


setNotchTarget

public final void setNotchTarget(double notchTarget)
This variable holds the number of pixel between notches. The default value is 0.0.

See also:
QDial::notchTarget().


notchTarget

public final double notchTarget()
This variable holds the number of pixel between notches. The default value is 0.0.

See also:
QDial::notchTarget().


setMaximum

public final void setMaximum(int maximum)
This variable holds the maximum value for the slider. The default value is 0.


maximum

public final int maximum()
This variable holds the maximum value for the slider. The default value is 0.


setSliderPosition

public final void setSliderPosition(int sliderPosition)
This variable holds the position of the slider handle. If the slider has active feedback (i.e., QAbstractSlider::tracking is true), this value will be the same as sliderValue. Otherwise, it will have the current position of the handle. The default value is 0.

See also:
QAbstractSlider::tracking, and sliderValue.


sliderPosition

public final int sliderPosition()
This variable holds the position of the slider handle. If the slider has active feedback (i.e., QAbstractSlider::tracking is true), this value will be the same as sliderValue. Otherwise, it will have the current position of the handle. The default value is 0.

See also:

See also:
QDial::wrapping().


setSliderValue

public final void setSliderValue(int sliderValue)
This variable holds the value of the slider. If the slider has active feedback (i.e., QAbstractSlider::tracking is true), this value will be the same as sliderPosition. Otherwise, it will have the value the slider had before the mouse was pressed.

The default value is 0.

setUpsideDown

public final void setUpsideDown(boolean upsideDown)
