## com.install4j.api.beaninfo
Class Install4JPropertyDescriptor

    java.lang.Object
      java.beans.FeatureDescriptor
          java.beans.PropertyDescriptor
              com.install4j.api.beaninfo.Install4JPropertyDescriptor

Direct Known Subclasses:
  FilePropertyDescriptor, ScriptPropertyDescriptor

    public class Install4JPropertyDescriptor

extends java.beans.PropertyDescriptor

Property descriptor for use in instances of `Install4JBeanInfo`. For file and script properties, derived classes are available.

Using this class is not strictly required. In principle, you could also set values for the `ATTRIBUTE_*` constants in the property descriptor of an unrelated property descriptor class.

### create

    public static Install4JPropertyDescriptor create(java.lang.String propertyName,
                                                     java.lang.Class beanClass,

                                                     java.lang.String context)

  Create a property descriptor that can be passed to `Install4JBeanInfo.addPropertyDescriptor(Install4JPropertyDescriptor)`.

  Parameters:
    `propertyName` - the name of the property
    `beanClass` - the class of the bean that contains th property. Note:This is not the class of the property.
    `displayName` - the display name of the property
    `shortDescription` - a short description of the property
    `context` - the context of the property. The context allows to specify different editors for the same property types. See the `CONTEXT_*` properties for the built-in contexts. This context is also used for enumerated properties in the `EnumerationMapper`. For properties of type `String[]`, you can pass an item name as the context.
  Returns:
    the property descriptor

### setContext

    public void setContext(java.lang.String editorContext)

  Set the context for the property.

  Parameters:
    `editorContext` - the context
  See Also:
    `for an explanation of the context.`

### setPropertyCategory

    public void setPropertyCategory(java.lang.String propertyCategory)

  Configures the property category. In the install4j GUI, properties are grouped by their categories. If no category has been specified, the default "Configuration" category is used.

  You can collapse certain categories by default with the `Install4JBeanInfo.setCollapsedPropertyCategories(String[])` method.

  Parameters:
    `propertyCategory` - the category

### setDisplayName

    public void setDisplayName(java.lang.String displayName)

  Overrides:
    `setDisplayName` in class `java.beans.FeatureDescriptor`

### setSortKey

    public void setSortKey(java.lang.Integer sortKey)

  Set an integer key by which properties are sorted. If no sort keys are specified, the properties will be sorted in the order they were added to the bean info.

  Parameters:
    `sortKey` - the sort key
  See Also:
    `Install4JBeanInfo.addPropertyDescriptor(Install4JPropertyDescriptor)`

### setPropertyChangeListener

    public void setPropertyChangeListener(java.beans.PropertyChangeListener listener)

  Set a property change listener that is invoked when the property is changed in the IDE. The source of the change event is the bean itself.

  Parameters:
    `listener` - the listener
