 /*! \brief Namespace for a set of classes implementing generic properties framework.
 
  Main classes of this framework are:
   - Property, representing a single property with its own type and value
   - Set, a set of properties
   - Editor, a widget for displaying and editing properties provided by a Set object.
     Every property has its own row displayed using EditorItem object, within Editor widget.
     Widget class provides editing feature for EditorItem objects if a user selects a given item.
 
  KProperty framework also supports adding composed and property types
  and custom property editor types.
 
  Take a look at the test application, available in the test/ directory
  to see example uses of the framework.

 /*! \brief The base class representing a single property
 
   It can hold a property of any type supported by QVariant. You can also create you own property
   types (see Using Custom Properties in Factory doc). As a consequence, do not subclass Property,
   use \ref KComposedPropertyInterface instead. \n
   Each property stores old value to allow undo. It has a name (a QByteArray), a caption
   (user-visible translated name shown in Editor) and a description (also translated). \n
   It also supports setting arbitrary number of options (of type option=value).
   See Editor for a list of options, and their meaning.
 
   \code
   // To create a property
   property = Property(name, value, caption, description); // name is a QByteArray,
   // value is whatever type QVariant supports
 
   // To create a valueFromList property (matching strings with strings)
   QStringList keys, strings;
   keys << "one" << "two" << "three"; // possible values of the property
   // Strings (possibly translated) shown in the editor instead of the values
   strings << tr("One") << tr("Two") << tr("Three");
   property = Property(name, keys, strings, "two", caption);
 
   // To create a valueFromList property (matching strings with QVariant)
   QValueList<QVariant> keys2;
   keys2.append(1);
   keys2.append(2);
   keys2.append(3);
   Property::ListData listData(keys2, strings);
   m_set->addProperty(new Property("List2", listData, "otheritem", "List2"), group);
   \endcode
 
   Note that you need to use QVariant(bool, int) to create a boolean property value.
   See QVariant docs for more details.
 
   Sometimes, for longer property captions or these with more words, e.g. "Allow Zero Size",
   its usable to provide newline characters, e.g. "Allow Zero\nSize".
   If caption argument of the constructors contains newline characters,
   caption() will return this text with substituted these characters with spaces.
   In such cases, captionForDisplaying() is used to get the original caption text usable
   (with newline, if any) for displaying within a property editor.

+         @see QAbstractSpinBox::specialValueText</li>
+    <li> max: integer describing minimum value for properties of integer type. Default is 0xffff.</li>
+    <li> precision: integer value describing the number of decimals after the decimal point
+         for double type.</li>
+    <li> step: integer describing the size of the step that is taken when the user hits
+         the up or down button of editor for double type.</li>
+    <li> 3State: boolean value used for boolean type; if @c true, the editor becomes a combobox
+         (instead of checkable button) and accepts the third "null" state.</li>
+    <li> yesName: user-visible translated string used for boolean type (both 2- and 3-state)
+         to visually represent the "true" value. If not present, tr("Yes") is used.</li>
+    <li> noName: user-visible translated string used for boolean type (both 2- and 3-state)
+         to visually represent the "false" value. If not present, tr("No") is used.</li>
+    <li> 3rdStateName: user-visible translated string used for boolean type (both 2- and 3-state)
+         to visually represent the third "null" value. If not present, tr("None") is used.</li>
+    <li> nullName: user-visible translated string used for boolean type to display the "null"
+         value, if and only if the property accepts two states (i.e. when "3State" option
+         is @c false). If the "nullName" option is not set, null values are displayed as

+    <li> extraValueAllowed: boolean value, if @c true the user is able to manually add extra
+         values to a combobox.</li>

-         widget's property</li>
-    <li> max: integer setting for minimum value the property of integer type. Default is 0xffff.</li>
-    <li> precision:  The number of decimals after the decimal point (for double types).</li>
-    <li> step: the size of the step that is taken when the user hits the up
-    or down buttons (for double types).</li>

-    <li> yesName: user-visible translated string used for boolean types (both 2- and 3-state)
-         to display the "true" value. If not present, tr("Yes") is used.</li>
-    <li> noName: user-visible translated string used for boolean types (both 2- and 3-state)

-    <li> 3rdStateName: user-visible translated string used for boolean types (both 2- and 3-state)
-         to display the 3rd state "null" value. If not present, tr("None") is used.</li>
-    <li> nullName: user-visible translated string used for boolean types to display the "null" value if
-         and only if the property accepts two states (i.e. when "3State" option is not true).
-         If this option is not present, null values are displayed as false.</li>
-    <li> extraValueAllowed: Allow the user to manually enter a value into a combobox
-         that is not in the list. The entered text will be returned as opposed to a matching key.</li>
-    <li> fileMode: indicates what the user may select in the file dialog for the url type's editor:
