These are: completion( const TQString& ), - * textRotation( KeyBindingType ), and returnPressed( const TQString& ). - * 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 TQString& ) 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 completionObject( bool ) member function for the first time or - * use setCompletionObject( KCompletion*, bool ) to assign your own - * completion object. Additionally, to make this widget more functional, - * KLineEdit 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 @p 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 KStdAccel. These values, however, can - * be overridden locally by invoking @p setKeyBinding(). You can easily - * revert these settings back to the default by simply calling - * @p useGlobalSettings(). An alternate method would be to default - * individual key-bindings by using setKeyBinding() with the default - * second argument. - * - * If @p EchoMode for this widget is set to something other than @p TQLineEdit::Normal, - * the completion mode will always be defaulted to KGlobalSettings::CompletionNone. - * This is done purposefully to guard against protected entries such as passwords being - * cached in KCompletion's list. Hence, if the @p EchoMode is not TQLineEdit::Normal, the - * completion mode is automatically disabled. - * - * A read-only KLineEdit will have the same background color as a - * disabled KLineEdit, but its foreground color will be the one used - * for the read-write mode. This differs from QLineEdit's implementation - * and is done to give visual distinction between the three different modes: - * disabled, read-only, and read-write. - * - * \b Usage \n - * - * To enable the basic completion feature : - * - * \code - * KLineEdit *edit = new KLineEdit( this, "mywidget" ); - * KCompletion *comp = edit->completionObject(); - * // Connect to the return pressed signal - optional - * connect(edit,TQT_SIGNAL(returnPressed(const TQString&)),comp,TQT_SLOT(addItem(const TQString&))); - * \endcode - * - * To use a customized completion objects or your - * own completion object : - * - * \code - * KLineEdit *edit = new KLineEdit( this,"mywidget" ); - * KURLCompletion *comp = new KURLCompletion(); - * edit->setCompletionObject( comp ); - * // Connect to the return pressed signal - optional - * connect(edit,TQT_SIGNAL(returnPressed(const TQString&)),comp,TQT_SLOT(addItem(const TQString&))); - * \endcode - * - * Note if you specify your own completion object you have to either delete - * it when you don't need it anymore, or you can tell KLineEdit to delete it - * for you: - * \code - * edit->setAutoDeleteCompletionObject( true ); - * \endcode - * - * <b>Miscellaneous function calls :</b>\n - * - * \code - * // Tell the widget to not handle completion and iteration automatically. - * edit->setHandleSignals( false ); - * - * // Set your own key-bindings for a text completion mode. - * edit->setKeyBinding( KCompletionBase::TextCompletion, Qt::End ); - * - * // Hide the context (popup) menu - * edit->setContextMenuEnabled( false ); - * - * // Temporarily disable signal (both completion & iteration) emitions - * edit->disableSignals(); - * - * // Default the key-bindings back to the default system settings. - * edit->useGlobalKeyBindings(); - * \endcode - * - * @author Dawit Alemayehu <[email protected]> - */ - -class KDEUI_EXPORT KLineEdit : public TQLineEdit, public KCompletionBase -{ - friend class KComboBox; - - Q_OBJECT - Q_PROPERTY( bool contextMenuEnabled READ isContextMenuEnabled WRITE setContextMenuEnabled ) - Q_PROPERTY( bool urlDropsEnabled READ isURLDropsEnabled WRITE setURLDropsEnabled ) - Q_PROPERTY( bool trapEnterKeyEvent READ trapReturnKey WRITE setTrapReturnKey ) - Q_PROPERTY( bool enableSqueezedText READ isSqueezedTextEnabled WRITE setEnableSqueezedText ) - // @since 3.5.4 - Q_PROPERTY( TQString clickMessage READ clickMessage WRITE setClickMessage ) - -public: - - /** - * Constructs a KLineEdit 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 - */ - KLineEdit( const TQString &string, TQWidget *parent, const char *name = 0 ); - - /** - * Constructs a KLineEdit object with a parent and a name. - * - * @param parent The parent object of this widget. - * @param name The name of this widget. - */ - KLineEdit ( TQWidget *parent=0, const char *name=0 ); - - /** - * Destructor. - */ - virtual ~KLineEdit (); - - /** - * Sets @p url into the lineedit.
