The eventFilter function must return true if the event should be filtered, (i.e.
Returns the children of this object that can be cast to grand palladium palace resort spa & casino best price zimmer type T and that have names matching the regular expression regExp, or an empty list if there are no such objects.
Note: bing images panda This macro takes care of registering individual flag values with the meta-object system, so it is unnecessary to lotto online spielen schleswig holstein use Q_enums in addition to this macro.
If the signal is queued, the parameters must be of types that are known to Qt's meta-object system, because Qt needs to copy the arguments to store them in an event behind the scenes.Here's a KeyPressEater class that eats the key presses of its monitored objects: class KeyPressEater : public QObject Q_object.For this object to the debug output.; See the Plug Paint Basic Tools example for details.Bool QObject:setProperty(const char * name, const QVariant value ) Sets the value of the object's name property to value.In both cases you can only rely on the child being a QObject, or if isWidgetType returns true, a QWidget.See also removeEventFilter eventFilter and event.Example: See also staticMetaObject.Void QObject:dumpObjectInfo Dumps information about signal connections, etc.Note: It is safe to call this function more than once; when the first deferred deletion event is delivered, any pending events for the object are removed from the event queue.



Virtual protected void QObject:customEvent( QEvent * event ) This event handler can be reimplemented in a subclass to receive custom events.
Installing or removing translators while performing translations is not supported.
In that case, findChildren should be used.
Void QObject:installEventFilter( QObject * filterObj ) Installs an event filter filterObj on this object.Protected QObject * QObject:sender const Returns a pointer to the object that sent the signal, if called in a slot activated by a signal; otherwise it returns.Many signals can be connected to one slot.The filter can either stop the event or forward it to this object.Header: #ifndef mainwindow_H #define mainwindow_H #include QMainWindow namespace Ui class MainWindow; class MainWindow : public QMainWindow, q_object public: explicit MainWindow(QWidget *parent 0 MainWindow private slots: void on_startBtn_clicked void update private: Ui:MainWindow *ui; ; #endif / mainwindow_H, implentation: #include "mainwindow.If you return false, Qt sends the event to the deleted object and the program will crash.If the property is defined in the class using Q_property then true is returned on success and false otherwise.See also senderSignalIndex and QSignalMapper.The macro is normally used when no _keywords is specified with the config variable in the.pro file, but it can be used even when no _keywords is not specified.See also deleteLater and QPointer.All the objects's children are destroyed immediately after this signal is emitted.Bool QObject:signalsBlocked const Returns true if signals are blocked; otherwise returns false.If Qt is unable to deliver the requested number of timer events, it will silently discard some.Q_enums(.) This macro registers one or several enum types to the meta-object system.
