QStateMachine example

This code example uses QState, which inherits QAbstractState. The QState class provides a state that you can use to set properties and invoke methods on QObject s when the state is entered or exited. It also contains convenience functions for adding transitions, e.g., QSignalTransition s as in this example The Move Blocks example shows how to animate items in a QGraphicsScene using a QStateMachine with a custom transition. Pad Navigator Example . Demonstrates how to create animated user interface. Ping Pong States Example. The Ping Pong States example shows how to use parallel states together with custom events and transitions in Qt State Machine Framework. Rogue Example. The Rogue example shows. Example: QStateMachine machine; QState *s1 = new QState(&machine); QPushButton button; QSignalTransition *trans = new QSignalTransition(&button, SIGNAL(clicked())); s1->addTransition(trans); QMessageBox msgBox; msgBox.setText(The button was clicked; carry on.); QObject::connect(trans, SIGNAL(triggered()), &msgBox, SLOT(exec())); machine.setInitialState(s1) For example (within a class): void setup() { QState *s2 = new QState(); s2->assignProperty(myLabel, text, state two); s2->setProperty(prop, 0); connect(s2, SIGNAL(entered()), io, SLOT(testSlot())); } Q_SLOT void testSlot() { QObject *obj = this->sender(); QVariant prop = obj->property(prop); qDebug() << __FUNCTION__ << prop.toString();

The PySide.QtCore.QStateMachine.started() signal is emitted when the initial state is entered. The machine is event driven and keeps its own event loop. Events are posted to the machine through PySide.QtCore.QStateMachine.postEvent(). Note that this means that it executes asynchronously, and that it will not progress without a running event loop. You will normally not have to post events to the machine directly as Qt's. In your Windows Exploerer go to where you downloaded and extracted the QtQuick Sample Application, the directory structure should look something like this: Now in the root directory create a new folder and call it QtQuickSampleApp and copy everything into it (you should now have QtQuickSampleApp\QtQuickSampleApp\QtQuickSampleApp.pro ) Traceback (most recent call last): File eventtrans.py, line 91, in <module> mainWin = MainWindow() File eventtrans.py, line 52, in __init__ machine = QStateMachine(self) NameError: name 'QStateMachine' is not defined Another functions is work fine. e.g. show main window of pyside6.

A working example is discussed and analysed in detail. Full qmake project and C++ source code are provided. C++ unit testing with Qt Test. Qt Test is a framework for C++ unit testing. It is part of Qt, which means it includes features to test Qt GUIs and other Qt elements like signals, but it can also be used to test plain (no Qt) C++ code. In this tutorial I am going to explain how to use Qt. Perhaps the example below will help provide insight into what state machines can be used for. STATE MACHINES. Before we get into implementing a simple state machine in Python lets quickly go over what a state machine is and what it looks like. In short, it's basically a set of states and a set of actions/events, we start at one state and like a graph data structure, we can traverse through. This code example uses QState, which inherits QAbstractState. The-131: QState class provides a state that you can use to set properties -132: and invoke methods on \l{QObject}s when the state is entered or-133: exited. It also contains convenience functions for adding-134: transitions, e.g., \l{QSignalTransition}s as in this example. See-135: the QState class description for further details. QStateMachine:: QStateMachine (QObject *parent = nullptr) Constructs a new state machine with the given parent. [signal] void QStateMachine:: runningChanged (bool running) This signal is emitted when the running property is changed with running as argument. This function was introduced in Qt 5.4.

Note: Notifier signal for property running. See also.

QStateMachine:: QStateMachine (QState::ChildMode childMode, QObject *parent = nullptr) Constructs a new state machine with the given childMode and parent. This function was introduced in Qt 5.0. [virtual] QStateMachine:: ~QStateMachine Destroys this state machine. void QStateMachine:: addDefaultAnimation (QAbstractAnimation *animation The Qt state machine framework is a good example. This API allows you to configure a state machine using compact code. You don't have to care about details of state machine execution semantics, as these are already implemented by the framework. You still have to write code, and as your state machine becomes more complex and contains some dozens or even hundreds of states, it will become really hard to get an overview. A picture is worth a thousand words, and the well-known.

The Event Transitions Example illustrates how states change when a user enters or leaves the area of a button. The states are handled by a QStateMachine object. The screen consists of a QVBoxLayout with a central button.. When the mouse is outside the button, the text in the button displays Outside Traffic Light Example. The Traffic Light example shows how to use The State Machine Framework to implement the control flow of a traffic light. In this example we write a TrafficLightWidget class. The traffic light has three lights: Red, yellow and green. The traffic light transitions from one light to another (red to yellow to green to yellow. Traffic Light Example: Qt 5.13.1 Reference Documentation: Traffic Light Example. The Traffic Light example shows how to use The State Machine Framework to implement the control flow of a traffic light. In this example we write a TrafficLightWidget class. The traffic light has three lights: Red, yellow and green. The traffic light transitions from one light to another (red to yellow to green to. So following is my sample code for prince sprite which use QStateMachine to maintain sprite's state and transition from one state to another. From somewhere in Internet I found sprite sheet for Prince of Persia, to make it easy for sample code I created another simple version of original sprite sheet. PrinceSprite::PrinceSprite(QGraphicsItem * parent):QGraphicsObject(parent) {mSpriteImage. Qt State Machine Framework (6/7) Usage QPushButton button(StateMachine Button); button.show(); QStateMachine machine; QState *state1 = new QState(); state1-assignProperty(button, geometry, QRect(200, 200, 100, 100)); QState *state2 = new QState(); state2-assignProperty(button, geometry, QRect(450, 450, 100, 100)); QFinalState *state3 = new QFinalState(); QSignalTransition *transition1 = state1-addTransition(button, SIGNAL(clicked()), state2); transition1-addAnimation(new.

In the example below, I've also defined a State object which will handle some utility functions for our states (which extend from this object). # state.py class State ( object ): We define a state object which provides some utility functions for the individual states within the state machine Quick Example C++ void my_event_action(state_machine<states,events>::state::event_ptr event, state_machine<states,events>::state_ptr current_state, state_machine<states,events>::state_ptr next_state) setGlobalRestorePolicy ( QStateMachine::RestorePolicy ) setInitialState ( QAbstractState * ) setObjectName ( const QString & ) setParent ( QObject * ) setProperty ( const char *, const QVariant & ) : bool; signalsBlocked const : bool; start startTimer ( int ) : int; started staticMetaObject: const QMetaObject; staticQtMetaObject: const QMetaObject; stop stopped ( class Worker: public QObject {Q_OBJECT QSslSocket sslSocket; QTimer timer; QStateMachine machine; QState s1, s2, s3; Q_SIGNAL void finished (); public: explicit Worker (QObject * parent = 0): QObject (parent), sslSocket (this), timer (this), machine (this), s1 (& machine), s2 (& machine), s3 (& machine) {timer. setSingleShot (true); s1. addTransition (& sslSocket, SIGNAL (encrypted ()), & s2); s1. addTransition (& timer, SIGNAL (timeout ()), & s3); connect (& s1, & QState:: entered, [this.

Qt 4.6: The State Machine Framewor

Edit: a secondary question - is it possible explicitly set up a transition from a state back into itself? For example, ZoomTrack needs to be re-entered each time the mouse moves so the current mouse position can be updated (and a new rubberband drawn). Can I add a transition from ZoomTrack to ZoomTrack on QEvent::MouseMove? 9th October 2011, 05:29. d_stranz. Re: Help using QStateMachine.

c++ - How to implement QStateMachine state transition

The QStateMachine class provides a hierarchical finite state machine. This code example uses QState, which inherits QAbstractState. The QState class provides a state that you can use to set properties and invoke methods on QObjects when the state is entered or exited. It also contains convenience functions for adding transitions, e.g., QSignalTransitions as in this example. See the QState. Factorial States Example: Qt 5.7.1 Reference Documentation: Factorial States Example. The statechart for calculating the factorial looks as follows: In other words, the state machine calculates the factorial of 6 and prints the result. class Factorial : public QObject { Q_OBJECT Q_PROPERTY(int x READ x WRITE setX) Q_PROPERTY(int fac READ fac WRITE setFac) public: Factorial(QObject * parent = 0. The PySide.QtCore.QFinalState class provides a final state.. A final state is used to communicate that (part of) a PySide.QtCore.QStateMachine has finished its work. When a final top-level state is entered, the state machine's PySide.QtCore.QStateMachine.finished() signal is emitted. In general, when a final substate (a child of a PySide.QtCore.QState) is entered, the parent state's PySide.

Only OpenGL has example effects and can be done using QML. 3. Improper animation 3.1 GIF Animation. In practical projects, we often encounter the need to play GIF animation. This kind of animation is not strict animation, it needs to use QMovie class to carry out Secondly, the QStateMachine::postEvent() function is _not_ thread-safe, meaning that it's not safe to call postEvent() on the _same_ machine from different threads; you'll have to manage the synchronization yourself if you want to do so (but maybe QStateMachine::postEvent() should be made thread-safe, like QCoreApplication::postEvent()?). Thirdly, if you're using signal transitions, there is.

18 ** Alternatively, this file may be used under the terms of the GNU Lesse The PySide.QtCore.QEvent class is the base class of all event classes. Event objects contain event parameters. Qt's main event loop ( QCoreApplication.exec()) fetches native window system events from the event queue, translates them into QEvents, and sends the translated events to PySide.QtCore.QObject s. In general, events come from the underlying window system ( PySide.QtCore.QEvent.

Examples include: QActive::postLIFO(), FreeRTOS xQueueSendToFront(), or even from the first major RTOS I used: pSOS's q_urgent(). A negative example would be a state machine based on Qt's QStateMachine [5], which would not enable this concept To demonstrate how this ties back together, I've prepared a little header file that does the declarative constructor magic, and created, as an example, a binding to QStateMachine. The code for a state machine, that would normally look like a bunch of setThis/setThat now looks like this POLLIN on PUB-SUB should work as an introduction, Killing the workers is meant as a next example. 4.

In more advanced cases, GammaRay provides a view on the internal QtQuick2 scene graph, which is especially useful when working on custom items. GammaRay is able to visualize a QStateMachine in an UML-like fashion, and show you the state it live. It's also capable of tracing all transitions of the state machine, helping you in analyzing misbehavior For example if you look at the mod tools for RPG engines like Aurora, Creation Kit and REDEngine you'll see that they have inherent knowledge about base item types like armor, monster, etc, but they rely on data for the specific items (and scripts for the exceptional behavior). The easiest to see that is with the Creation Kit based games like Skyrim since it gives you a nice GUI to create/edit.
