public final class PuInteger

extends PsObject

Basic integer class with update functionality and panel containing a slider. This class may always be used when a integer instance variable shall be modifiable by a slider in the info panel of its parent class. See the class PjExprOde as a sample application.

Usage demonstrated in a sample class:

	 public class PjExprOde {
		protected  PuInteger  m_length;
		public PjExprOde() {
			// Create a new instance of PuInteger and register 'this' as parent
			// to receive update events whenever user has modified the slider.
			m_length		= new PuInteger("Length", this);
			init();
		}
		public void init() {
			// Set default value to be assigned when user resets slider
			// using a call m_length.init().
			m_length.setDefValue(15);
			// Set default min/max values and increments of slider.
			m_length.setDefBounds(1, 50, 1, 10);
			// Reset to default values.
			m_length.init();
		}
		public boolean update(Object event) {
			// Catch update events sent whenever user has modifed slider.
			if (event == m_length) {
				// Do something application depended
				solve();
				return true;
			}
		}
		public void solve() {
			// Access current value
			System.out.println("Current value = "+m_length.getValue());
		}
  }

Constructor Detail

PuInteger

public PuInteger(java.lang.String aName,
                 PsUpdateIf aParent)

Create new instance with given name and parent. The name appears as label on the slider, and the parent is informed whenever the slider has changed using aParent.update(this).

Parameters:

aName - Name of integer to appear as label in slider.

aParent - Parent of integer to receive update events.

Method Detail

init

public void init()

Assign default values, and may be used to reset instance.

Overrides:

init in class PsObject

copy

public void copy(PuInteger num)

Copy all instance variables of argument source into 'this'.

setDefValue

public void setDefValue(int value)

Set default value to be assigned when init() is called as reset.

See Also:

setDefBounds(int, int, int, int)

getDefMinimum

public int getDefMinimum()

Get the default minimum value which are used when slider is reset. Current value of slider is clipped to lie within [min,max] bounds.

See Also:

setDefBounds(int, int, int, int), setBounds(int, int, int, int)

getDefMaximum

public int getDefMaximum()

Get the default maximum value which are used when slider is reset. Current value of slider is clipped to lie within [min,max] bounds.

See Also:

setDefBounds(int, int, int, int), setBounds(int, int, int, int)

getDefLineIncr

public int getDefLineIncr()

Get the default line increment which are used when slider is reset.

See Also:

setDefBounds(int, int, int, int), setBounds(int, int, int, int)

getDefPageIncr

public int getDefPageIncr()

Get the default page increment which are used when slider is reset.

See Also:

setDefBounds(int, int, int, int), setBounds(int, int, int, int)

setDefBounds

public void setDefBounds(int aMin,
                         int aMax,
                         int aLineIncr,
                         int aPageIncr)

Set default min/max values and slider increments to be assigned when init() is called as reset. Current value of slider is clipped to lie within [min,max] bounds.

setValue

public void setValue(int aValue)

Set value of integer, and adjust slider if visible. If new value is outside the current bounds, then the new value is clipped to lie within the bounds. This routine called from outside to set the value. Only here we update the panel.

getValue

public int getValue()

Get current integer value.

getMin

public int getMin()

Get minimal value allowed in slider. May be interactively modified with config panel.

getMax

public int getMax()

Get maximal value allowed in slider. May be interactively modified with config panel.

getLineIncr

public int getLineIncr()

Get line increment of slider. May be interactively modified with config panel.

getPageIncr

public int getPageIncr()

Get block increment of slider. May be interactively modified with config panel.

setBounds

public void setBounds(int aMin,
                      int aMax,
                      int aLineIncr,
                      int aPageIncr)

Set current min/max values and slider increments. Adjust value if current value lies outside the new min/max bounds. These bounds will be overriden if instance is reset using init().

Parameters:

aMin, - aMax Minimal and maximal values in slider.

aLineIncr - Line increment used in slider.

aPageIncr - Block increment used in slider.

setBounds

public void setBounds(int aMin,
                      int aMax)

Set current min/max values and adjust value if current value lies outside the new min/max bounds. These bounds will be overriden if instance is reset using init(). Line and block increments of slider are set to default values.

Parameters:

aMin, - aMax Minimal and maximal values in slider.

isEnabled

public boolean isEnabled()

Check whether slider is enabled or disabled.

setEnabled

public void setEnabled(boolean flag)

Enable or disable the slider for interactive use. If disabled, the integer variable can still be modified by calls setValue(integer), and the slider is always updated.

update

public boolean update(java.lang.Object anObject)

Catch update events sent from info panel.

Overrides:

update in class PsObject
