| SSlider | | public class SSlider extends SComponent implements SConstants,LowLevelEventListener(Code) | | A component that lets the user graphically select a value by sliding
a knob within a bounded interval.
The displayed slider is highly dependent on the graphics used,

| Field Summary | |
| protected ChangeListener | changeListener
The changeListener (no suffix) is the listener we add to the
Sliders model. | | protected int | majorTickSpacing
The number of values between the major tick marks. | | protected int | orientation
| | protected BoundedRangeModel | sliderModel
The data model that handles the numeric maximum value,
minimum value, and current-position value for the slider. | | protected boolean | snapToTicks
If true, the knob (and the data value it represents)
resolve to the closest tick mark next to where the user
positioned the knob. |
| Constructor Summary | |
| public | SSlider()
Creates a horizontal slider with the range 0 to 100 and
an initial value of 50. | | public | SSlider(int orientation)
Creates a slider using the specified orientation with the
range 0 to 100 and an initial value of 50. | | public | SSlider(int min, int max)
Creates a horizontal slider using the specified min and max
with an initial value equal to the average of the min plus max. | | public | SSlider(int min, int max, int value)
Creates a horizontal slider using the specified min, max and value. | | public | SSlider(int orientation, int min, int max, int value)
Creates a slider with the specified orientation and the
specified minimum, maximum, and initial values. |
| majorTickSpacing | | protected int majorTickSpacing(Code) | | The number of values between the major tick marks.
|
| sliderModel | | protected BoundedRangeModel sliderModel(Code) | | The data model that handles the numeric maximum value,
minimum value, and current-position value for the slider.
|
| snapToTicks | | protected boolean snapToTicks(Code) | | If true, the knob (and the data value it represents)
resolve to the closest tick mark next to where the user
positioned the knob. The default is false.

| SSlider | | public SSlider()(Code) | | Creates a horizontal slider with the range 0 to 100 and
an initial value of 50.
|
| SSlider | | public SSlider(int orientation)(Code) | | Creates a slider using the specified orientation with the
range 0 to 100 and an initial value of 50.
|
| SSlider | | public SSlider(int min, int max)(Code) | | Creates a horizontal slider using the specified min and max
with an initial value equal to the average of the min plus max.
|
| SSlider | | public SSlider(int min, int max, int value)(Code) | | Creates a horizontal slider using the specified min, max and value.
|
| createChangeListener | | protected ChangeListener createChangeListener()(Code) | | Subclasses that want to handle model ChangeEvents differently
can override this method to return their own ChangeListener
implementation. The default ChangeListener just forwards
ChangeEvents to the ChangeListeners added directly to the slider.
See Also: SSlider.fireStateChanged |
| fireFinalEvents | | public void fireFinalEvents()(Code) | | |
| fireIntermediateEvents | | public void fireIntermediateEvents()(Code) | | |
| fireStateChanged | | protected void fireStateChanged()(Code) | | Notifies all listeners that have registered interest in
ChangeEvents.
|
| getChangeListeners | | public ChangeListener[] getChangeListeners()(Code) | | Returns an array of all the ChangeListeners added
to this slider with addChangeListener.
all of the ChangeListeners added or an emptyarray if no listeners have been added |
| getMajorTickSpacing | | public int getMajorTickSpacing()(Code) | | This method returns the major tick spacing. The number that is returned
represents the distance, measured in values, between each major tick mark.
If you have a slider with a range from 0 to 50 and the major tick spacing
is set to 10, you will get major ticks next to the following values:
0, 10, 20, 30, 40, 50.
the number of values between major ticks
See Also: SSlider.setMajorTickSpacing |
| getMaximum | | public int getMaximum()(Code) | | Returns the maximum value supported by the slider.
the value of the models maximum property
See Also: SSlider.setMaximum |
| getMinimum | | public int getMinimum()(Code) | | Returns the minimum value supported by the slider.
the value of the models minimum property
See Also: SSlider.setMinimum |
| getOrientation | | public int getOrientation()(Code) | | Return this slider's vertical or horizontal orientation.
VERTICAL or HORIZONTAL
See Also: SSlider.setOrientation |
| getSnapToTicks | | public boolean getSnapToTicks()(Code) | | Returns true if the knob (and the data value it represents)
resolve to the closest tick mark next to where the user
positioned the knob.
true if the value snaps to the nearest tick mark, else false
See Also: SSlider.setSnapToTicks |
| getValue | | public int getValue()(Code) | | Returns the sliders value.
the models value property
See Also: SSlider.setValue |
| isEpochCheckEnabled | | public boolean isEpochCheckEnabled()(Code) | | |
| processLowLevelEvent | | public void processLowLevelEvent(String action, String[] values)(Code) | | |
| setMajorTickSpacing | | public void setMajorTickSpacing(int n)(Code) | | This method sets the major tick spacing. The number that is passed-in
represents the distance, measured in values, between each major tick mark.
If you have a slider with a range from 0 to 50 and the major tick spacing
is set to 10, you will get major ticks next to the following values:
0, 10, 20, 30, 40, 50.
See Also: SSlider.getMajorTickSpacing |
| setMaxPixelConstraint | | public void setMaxPixelConstraint(int max)(Code) | | The maximum number of pixels the slider thumb can be moved. Usefull when
using different slider thumb or bar graphics.
Parameters:
max - pixels |
| setSnapToTicks | | public void setSnapToTicks(boolean b)(Code) | | Specifying true makes the knob (and the data value it represents)
resolve to the closest tick mark next to where the user
positioned the knob.
Parameters:
b - true to snap the knob to the nearest tick mark
See Also: SSlider.getSnapToTicks |
| setValue | | public void setValue(int n)(Code) | | Sets the sliders current value. This method just forwards
the value to the model.
See Also: SSlider.getValue |
