public MutableIconProviderSupport()

Method Details

setIcon

public void setIcon(@Nonnull
 Icon icon)

Sets the icon. Note that implementations don't actually need to do something in this method: for instance, a valid MutableIconProvider can autonomously change icon in function of time (e.g. a blinking icon) or reacting to a change in the context. FIXME: this method does nothing. Probably this is inconsistent with DefaultMutableDisplayable? But that is a Default*, we're just a *Support...

Specified by:

setIcon in interface MutableIconProvider

Parameters:

icon - the icon

fireIconChange

protected void fireIconChange(@Nonnull
 Icon oldIcon,
 @Nonnull
 Icon newIcon)

Fires the event notifying that MutableIconProvider.PROP_ICON has been changed.

Parameters:

oldIcon - the old value of the property

newIcon - the new value of the property
