| BoundedRangeAdapter | | final public class BoundedRangeAdapter implements BoundedRangeModel,Serializable(Code) | | Converts a ValueModel to the BoundedRangeModel interface.
Honors an upper and lower bound and returns the adapter's minimum
in case the subject value is null.
Example:
int minSaturation = 0;
int maxSaturation = 255;
PresentationModel pm = new PresentationModel(settings);
ValueModel saturationModel = pm.getModel("saturation");
JSlider saturationSlider = new JSlider(
new BoundedRangeAdapter(saturationModel,
0,
minSaturation,
maxSaturation));

| Constructor Summary | |
| public | BoundedRangeAdapter(ValueModel subject, int extent, int min, int max)
Constructs a BoundedRangeAdapter on the given subject
using the specified extend, minimum and maximum values. |
| Method Summary | |
| public void | addChangeListener(ChangeListener l)
Adds a ChangeListener. | | protected void | fireStateChanged()
Runs each ChangeListeners stateChanged() method. | | public int | getExtent()
Returns this model's extent. | | public int | getMaximum()
Returns this model's upper bound, the maximum. | | public int | getMinimum()
Returns this model's lower bound, the minimum. | | public int | getValue()
Returns the current subject value, or the minimum if
the subject value is null. | | public boolean | getValueIsAdjusting()
Returns true if the value is in the process of changing
as a result of actions being taken by the user. | | public void | removeChangeListener(ChangeListener l)
Removes a ChangeListener. | | public void | setExtent(int n)
Sets the extent to n. | | public void | setMaximum(int n)
Sets the maximum to n. | | public void | setMinimum(int n)
Sets the minimum to n. | | public void | setRangeProperties(int newValue, int newExtent, int newMin, int newMax, boolean adjusting)
Sets all of the BoundedRangeModel properties after forcing
the arguments to obey the usual constraints:
minimum <= value <= value+extent <= maximum
At most, one ChangeEvent is generated. | | public void | setValue(int n)
Sets the current value of the model. | | public void | setValueIsAdjusting(boolean b)
Sets the valueIsAdjusting property. | | public String | toString()
Returns a string that displays all of the BoundedRangeModel properties. |
| BoundedRangeAdapter | | public BoundedRangeAdapter(ValueModel subject, int extent, int min, int max)(Code) | | Constructs a BoundedRangeAdapter on the given subject
using the specified extend, minimum and maximum values.
Parameters:
subject - the underlying ValueModel that provides the value
Parameters:
extent - the extent to be set
Parameters:
min - the minimum to be set
Parameters:
max - the maximum to be set
throws:
IllegalArgumentException - if the following constraints aren'tsatisfied: min <= initial subject value <= value+extent <= max |
| setExtent | | public void setExtent(int n)(Code) | | Sets the extent to n. Ensures that n
is greater than or equal to zero and falls within the adapter's
constraints:
minimum <= value <= value+extent <= maximum
Parameters:
n - the new extent before ensuring a non-negative number
See Also: BoundedRangeModel.setExtent(int) |
| setMaximum | | public void setMaximum(int n)(Code) | | Sets the maximum to n. Ensures that n
and the other three properties obey this adapter's constraints:
minimum <= value <= value+extent <= maximum
Parameters:
n - the new maximum before ensuring this adapter's constraints
See Also: BoundedRangeModel.setMaximum(int) |
| setValue | | public void setValue(int n)(Code) | | Sets the current value of the model. For a slider, that
determines where the knob appears. Ensures that the new
value, n falls within the model's constraints:
minimum <= value <= value+extent <= maximum
Parameters:
n - the new value before ensuring constraints
See Also: BoundedRangeModel.setValue(int) |
| toString | | public String toString()(Code) | | Returns a string that displays all of the BoundedRangeModel properties.
a string representation of the properties |
