+/**
+ * This class offers easy use of "auto-completion", "manual-completion" or
+ * "shell completion" on QString objects. A common use is completing filenames
+ * or URLs (see @ref OURLCompletion()).
+ * But it is not limited to URL-completion -- everything should be completable!
+ * The user should be able to complete email-addresses, telephone-numbers,
+ * commands, SQL queries, ...
+ * Every time your program knows what the user can type into an edit-field, you
+ * should offer completion. With OCompletion, this is very easy, and if you are
+ * using a line edit widget (@ref OLineEdit), it is even more easy.
+ * Basically, you tell a OCompletion object what strings should be completable
+ * and whenever completion should be invoked, you call @ref makeCompletion().
+ * OLineEdit and (an editable) OComboBox even do this automatically for you.
+ *
+ * OCompletion offers the completed string via the signal @ref match() and
+ * all matching strings (when the result is ambiguous) via the method
+ * @ref allMatches().
+ *
+ * Notice: auto-completion, shell completion and manual completion work
+ * slightly differently:
+ *
+ * @li auto-completion always returns a complete item as match.
+ * When more than one matching items are available, it will deliver just
+ * the first (depending on sorting order) item. Iterating over all matches
+ * is possible via @ref nextMatch() and @ref previousMatch().
+ *
+ * @li popup-completion works in the same way, the only difference being that
+ * the completed items are not put into the edit-widget, but into a
+ * separate popup-box.
+ *
+ * @li manual completion works the same way as auto-completion, the
+ * subtle difference is, that it isn't invoked automatically while the user
+ * is typing, but only when the user presses a special key. The difference
+ * of manual and auto-completion is therefore only visible in UI classes,
+ * OCompletion needs to know whether to deliver partial matches
+ * (shell completion) or whole matches (auto/manual completion), therefore
+ * @ref OGlobalSettings::CompletionMan and
+ * @ref OGlobalSettings::CompletionAuto have the exact same effect in
+ * OCompletion.
+ *
+ * @li shell completion works like how shells complete filenames:
+ * when multiple matches are available, the longest possible string of all
+ * matches is returned (i.e. only a partial item).
+ * Iterating over all matching items (complete, not partial) is possible
+ * via @ref nextMatch() and @ref previousMatch().
+ *
+ * You don't have to worry much about that though, OCompletion handles
+ * that for you, according to the setting @ref setCompletionMode().
+ * The default setting is globally configured by the user and read
+ * from @ref OGlobalSettings::completionMode().
+ *
+ * A short example:
+ * <pre>
+ * OCompletion completion;
+ * completion.setOrder( OCompletion::Sorted );
+ * completion.addItem( "pfeiffer@kde.org" );
+ * completion.addItem( "coolo@kde.org" );
+ * completion.addItem( "carpdjih@sp.zrz.tu-berlin.de" );
+ * completion.addItem( "carp@cs.tu-berlin.de" );
+ *
+ * cout << completion.makeCompletion( "ca" ).latin1() << endl;
+ * </pre>
+ * In shell-completion-mode, this will be "carp"; in auto-completion-
+ * mode it will be "carp@cs.tu-berlin.de", as that is alphabetically
+ * smaller.
+ * If setOrder was set to Insertion, "carpdjih@sp.zrz.tu-berlin.de"
+ * would be completed in auto-completion-mode, as that was inserted before
+ * "carp@cs.tu-berlin.de".
+ *
+ * You can dynamically update the completable items by removing and adding them
+ * whenever you want.
+ * For advanced usage, you could even use multiple OCompletion objects. E.g.
+ * imagine an editor like kwrite with multiple open files. You could store
+ * items of each file in a different OCompletion object, so that you know (and
+ * tell the user) where a completion comes from.
+ *
+ * Note: OCompletion does not work with strings that contain 0x0 characters
+ * (unicode nul), as this is used internally as a delimiter.
+ *
+ * You may inherit from OCompletion and override @ref makeCompletion() in
+ * special cases (like reading directories/urls and then supplying the
+ * contents to OCompletion, as OURLCompletion does), but generally, this is
+ * not necessary.

+/**
+ * A combined button, line-edit and a popup list widget.
+ *
+ * @sect Detail
+ *
+ * This widget inherits from @ref QComboBox and implements
+ * the following additional functionalities: a completion
+ * object that provides both automatic and manual text
+ * completion as well as text rotation features, configurable
+ * key-bindings to activate these features, and a popup-menu
+ * item that can be used to allow the user to set text completion
+ * modes on the fly based on their preference.
+ *
+ * To support these new features OComboBox also emits a few
+ * more additional signals as well. The main ones are the
+ * @ref completion( const QString& ) and @ref textRotation( KeyBindingType )
+ * signals. The completion signal is intended to be connected to a slot
+ * that will assist the user in filling out the remaining text while
+ * the rotation signals is intended to be used to traverse through all
+ * possible matches whenever text completion results in multiple matches.
+ * The @ref returnPressed() and @ref returnPressed( const QString& )
+ * signal is emitted when the user presses the Enter/Return key.
+ *
+ * This widget by default creates a completion object when you invoke
+ * the @ref completionObject( bool ) member function for the first time
+ * or use @ref setCompletionObject( OCompletion*, bool ) to assign your
+ * own completion object. Additionally, to make this widget more functional,
+ * OComboBox will by default handle the text rotation and completion
+ * events internally whenever a completion object is created through either
+ * one of the methods mentioned above. If you do not need this functionality,
+ * simply use @ref OCompletionBase::setHandleSignals( bool ) or alternatively
+ * set the boolean parameter in the above methods to FALSE.
+ *
+ * The default key-bindings for completion and rotation is determined
+ * from the global settings in @ref OStdAccel. These values, however,
+ * can be overriden locally by invoking @ref OCompletionBase::setKeyBinding().
+ * The values can easily be reverted back to the default setting, by simply
+ * calling @ref useGlobalSettings(). An alternate method would be to default
+ * individual key-bindings by usning @ref setKeyBinding() with the default
+ * second argument.
+ *
+ * Note that if this widget is not editable ( i.e. select-only ), then only
+ * one completion mode, @p CompletionAuto, will work. All the other modes are
+ * simply ignored. The @p CompletionAuto mode in this case allows you to
+ * automatically select an item from the list by trying to match the pressed
+ * keycode with the first letter of the enteries in the combo box.
+ *
+ * @sect Useage
+ *
+ * To enable the basic completion feature:
+ *
+ * <pre>
+ * OComboBox *combo = new OComboBox( true, this, "mywidget" );
+ * OCompletion *comp = combo->completionObject();
+ * // Connect to the return pressed signal - optional
+ * connect(combo,SIGNAL(returnPressed(const QString&)),comp,SLOT(addItem(const QString&));
+ * </pre>
+ *
+ * To use your own completion object:
+ *
+ * <pre>
+ * OComboBox *combo = new OComboBox( this,"mywidget" );
+ * OURLCompletion *comp = new OURLCompletion();
+ * combo->setCompletionObject( comp );
+ * // Connect to the return pressed signal - optional
+ * connect(combo,SIGNAL(returnPressed(const QString&)),comp,SLOT(addItem(const QString&));
+ * </pre>
+ *
+ * Note that you have to either delete the allocated completion object
+ * when you don't need it anymore, or call
+ * setAutoDeleteCompletionObject( true );
+ *
+ * Miscellaneous function calls:
+ *
+ * <pre>
+ * // Tell the widget not to handle completion and rotation
+ * combo->setHandleSignals( false );
+ * // Set your own completion key for manual completions.
+ * combo->setKeyBinding( OCompletionBase::TextCompletion, Qt::End );
+ * // Hide the context (popup) menu
+ * combo->setContextMenuEnabled( false );
+ * // Temporarly disable signal emition
+ * combo->disableSignals();
+ * // Default the all key-bindings to their system-wide settings.
+ * combo->useGlobalKeyBindings();
+ * </pre>
+ *
+ * @short An enhanced combo box.
+ * @author Dawit Alemayehu <adawit@kde.org>

+/**
+ * Provides a number of ready to use layouts (faces). It is used
+ * as an internal widget in @ref KDialogBase, but can also used as a
+ * widget of its own.
+ *
+ * It provides TreeList, IconList, Tabbed, Plain and Swallow layouts.
+ *
+ * The TreeList face provides a list in the left area and pages in the
+ * right. The area are separated by a movable splitter. The style is somewhat
+ * similar to the layout in the Control Center. A page is raised by
+ * selecting the corresponding tree list item.
+ *
+ * The IconList face provides an icon list in the left area and pages in the
+ * right. For each entry the Icon is on top with the text below. The style
+ * is somewhat similar to the layout of the Eudora configuation dialog box.
+ * A page is raised by selecting the corresponding icon list item. The
+ * preferred icon size is 32x32 pixels.
+ *
+ * The Tabbed face is a common tabbed widget. The procedure for creating a
+ * page is similar for creating a TreeList. This has the advantage that if
+ * your widget contain too many pages it is trivial to convert it into a
+ * TreeList. Just change the face in the KJanusWidget constructor to
+ * KJanusWidget::TreeList and you have a tree list layout instead.
+ *
+ * The Plain face provides an empty widget (QFrame) where you can place your
+ * widgets. The KJanusWidget makes no assumptions regarding the contents so
+ * you are free to add whatever you want.
+ *
+ * The Swallow face is provided in order to simplify the usage of existing
+ * widgets and to allow changing the visible widget. You specify the widget
+ * to be displayed by @ref #setSwallowedWidget(). Your widget will be
+ * reparented inside the widget. You can specify a Null (0) widget. A empty
+ * space is then displayed.
+ *
+ * For all modes it is important that you specify the @ref QWidget::minimumSize()
+ * on the page, plain widget or the swallowed widget. If you use a QLayout
+ * on the page, plain widget or the swallowed widget this will be taken care
+ * of automatically. The size is used when the KJanusWidget determines its
+ * own minimum size. You get the minimum size by using the
+ * @ref #minimumSizeHint() or @ref #sizeHint() methods.
+ *
+ * Pages that have been added in TreeList, IconList or Tabbed mode can be
+ * removed by simply deleting the page.
+ *
+ * @short Easy to use widget with many layouts

+ * This widget inherits from @ref QLineEdit and implements the following
+ * additional functionalities: q completion object that provides both
+ * automatic and manual text completion as well as multiple match iteration
+ * features, configurable key-bindings to activate these features and a
+ * popup-menu item that can be used to allow the user to set text completion
+ * modes on the fly based on their preference.
+ *
+ * To support these new features OLineEdit also emits a few more
+ * additional signals. These are: @ref completion( const QString& ),
+ * textRotation( KeyBindingType ), and @ref returnPressed( const QString& ).
+ * The completion signal can be connected to a slot that will assist the
+ * user in filling out the remaining text. The text rotation signal is
+ * intended to be used to iterate through the list of all possible matches
+ * whenever there is more than one match for the entered text. The
+ * @p returnPressed( const QString& ) signals are the same as QLineEdit's
+ * except it provides the current text in the widget as its argument whenever
+ * appropriate.
+ *
+ * This widget by default creates a completion object when you invoke
+ * the @ref completionObject( bool ) member function for the first time or
+ * use @ref setCompletionObject( OCompletion*, bool ) to assign your own
+ * completion object. Additionally, to make this widget more functional,
+ * OLineEdit will by default handle the text rotation and completion
+ * events internally when a completion object is created through either one
+ * of the methods mentioned above. If you do not need this functionality,
+ * simply use @ref OCompletionBase::setHandleSignals( bool ) or set the
+ * boolean parameter in the above functions to FALSE.
+ *
+ * The default key-bindings for completion and rotation is determined
+ * from the global settings in @ref OStdAccel. These values, however,
+ * can be overriden locally by invoking @ref OCompletionBase::setKeyBinding().
+ * The values can easily be reverted back to the default setting, by simply
+ * calling @ref useGlobalSettings(). An alternate method would be to default
+ * individual key-bindings by usning @ref setKeyBinding() with the default
+ * second argument.
+ *
+ * NOTE that if the @p EchoMode for this widget is set to something other
+ * than @p QLineEdit::Normal, the completion mode will always be defaulted
+ * to @ref PGlobalSettings::CompletionNone. This is done purposefully to guard
+ * against protected entries such as passwords being cached in @ref OCompletion's
+ * list. Hence, if the @p EchoMode is not @ref QLineEdit::Normal, the completion
+ * mode is automatically disabled.
+ *
+ * @sect Useage
+ *
+ * To enable the basic completion feature :
+ *
+ * <pre>
+ * OLineEdit *edit = new OLineEdit( this, "mywidget" );
+ * OCompletion *comp = edit->completionObject();
+ * // Fill the completion object with a list of possible matches
+ * QStringList list;
+ * list << "mickeyl@handhelds.org" << "mickey@tm.informatik.uni-frankfurt.de>" << "mickey@Vanille.de";
+ * comp->setItems( list );
+ * // Connect to the return pressed signal (optional)
+ * connect(edit,SIGNAL(returnPressed(const QString&)),comp,SLOT(addItem(const QString&));
+ * </pre>
+ *
+ * To use a customized completion objects or your
+ * own completion object :
+ *
+ * <pre>
+ * OLineEdit *edit = new OLineEdit( this,"mywidget" );
+ * KURLCompletion *comp = new KURLCompletion();
+ * edit->setCompletionObject( comp );
+ * // Connect to the return pressed signal - optional
+ * connect(edit,SIGNAL(returnPressed(const QString&)),comp,SLOT(addItem(const QString&));
+ * </pre>
+ *
+ * Note that you have to either delete the allocated completion object
+ * when you don't need it anymore, or call
+ * setAutoDeleteCompletionObject( true );
+ *
+ * @sect Miscellaneous function calls :
+ *
+ * <pre>
+ * // Tell the widget not to handle completion and
+ * // iteration internally.
+ * edit->setHandleSignals( false );
+ * // Set your own completion key for manual completions.
+ * edit->setKeyBinding( OCompletionBase::TextCompletion, Qt::End );
+ * // Hide the context (popup) menu
+ * edit->setContextMenuEnabled( false );
+ * // Temporarly disable signal emitions
+ * // (both completion & iteration signals)
+ * edit->disableSignals();
+ * // Default the key-bindings to system settings.
+ * edit->useGlobalKeyBindings();
+ * </pre>
+ *
