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.

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 + * @par Usage * * 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 : + * @par 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> * * @short An enhanced single line input widget. * @author Dawit Alemayehu <adawit@kde.org> * @author Opie adaption by Michael Lauer <mickey@tm.informatik.uni-frankfurt.de> */ class OLineEdit : public QLineEdit, public OCompletionBase { friend class OComboBox; Q_OBJECT Q_PROPERTY( bool contextMenuEnabled READ isContextMenuEnabled WRITE setContextMenuEnabled ) Q_PROPERTY( bool urlDropsEnabled READ isURLDropsEnabled WRITE setURLDropsEnabled ) public: /** * Constructs a OLineEdit object with a default text, a parent, * and a name. * * @param string Text to be shown in the edit widget. * @param parent The parent object of this widget. * @param name the name of this widget */ OLineEdit( const QString &string, QWidget *parent, const char *name = 0 ); /** * Constructs a OLineEdit object with a parent and a name. * * @param string Text to be shown in the edit widget. * @param parent The parent object of this widget. * @param name The name of this widget. */ OLineEdit ( QWidget *parent=0, const char *name=0 ); /** * Destructor. */ virtual ~OLineEdit (); /** * Sets @p url into the lineedit.
