GaugeLFImpl

• java.lang.Object
  • ItemLFImpl

Fields Summary
private Gauge	gauge Gauge instance associated with this view.

Constructors Summary
GaugeLFImpl(Gauge gauge) Creates GaugeLF for the passed in Gauge. param gauge the Gauge object associated with this look&feel. super(gauge); this.gauge = gauge;

Methods Summary
void	createNativeResource(int ownerId) Create native resource for current Gauge. Override function in ItemLFImpl. param ownerId Owner screen's native resource id nativeId = createNativeResource0(ownerId, gauge.label, gauge.layout, gauge.interactive, gauge.maxValue, gauge.value);
private native int	createNativeResource0(int ownerId, java.lang.String label, int layout, boolean interactive, int maxValue, int initialValue) KNI function that creates native resource for current Gauge. param ownerId Owner screen's native resource id (MidpDisplayable *) param label label string of this Item param layout layout directive associated with this Item param interactive indicates whether gauge is interactive or not param maxValue the maximum value for this gauge param initialValue the current value of the gauge return native resource id (MidpItem *) of this Gauge
boolean	equateNLA() Determine if this Item should have a newline after it. return true if it should have a newline after if (super.equateNLA()) { return true; } return ((gauge.layout & Item.LAYOUT_2) != Item.LAYOUT_2);
boolean	equateNLB() Determine if this Item should have a newline before it. return true if it should have a newline before if (super.equateNLB()) { return true; } return ((gauge.layout & Item.LAYOUT_2) != Item.LAYOUT_2);
public int	lGetValue() Gets the current value. return the current value return gauge.value;
public void	lSetMaxValue(int oldMaxValue, int newMaxValue) Notifies L&F of a maximum value change in the corresponding Gauge. param oldMaxValue the old maximum value set in the Gauge param newMaxValue the new maximum value set in the Gauge if (nativeId != DisplayableLFImpl.INVALID_NATIVE_ID) { // Only update native resource if it exists. setValue0(nativeId, gauge.value, newMaxValue); lRequestInvalidate(true, true); }
public void	lSetValue(int oldValue, int newValue) Notifies L&F of a value change in the corresponding Gauge. param oldValue the old value set in the Gauge param newValue the new value set in the Gauge // little optimization to avoid calling into native // in cases where unnecessary if (nativeId != DisplayableLFImpl.INVALID_NATIVE_ID) { // Only update native resource if it exists. setValue0(nativeId, newValue, gauge.maxValue); lRequestInvalidate(true, true); }
private native void	setValue0(int nativeId, int newValue, int newMaxValue) KNI function that sets the current and maximum values on the native resource corresponding to the current Gauge. param nativeId native resource id for this Item param newValue new value of the current Gauge param newMaxValue new maximum value of the current Gauge
boolean	uCallPeerStateChanged(int hint) Notification of a change in its peer state. Update Java peer with user input. param hint the new value of an interactive gauge return always true so to notify ItemStateListener synchronized (Display.LCDUILock) { // Update Java peer with the new value gauge.value = hint; } // Indicate to Form to notify ItemStateListener return true;
