qstatemachine

My problem is the following: I need to create class, which contains QStateMachine instance. This class should have slots through which you could "ask" state machine to make transition to another state. And if transition was successful, my class should emit signal about it. How would I implement this? Class should have ability to emit certain signals according to certain slot invoke. Here is a small example of class: class MyClass : public QObject { Q_OBJECT public: explicit MyClass(QObject *parent = 0) { mStateMachine = new QStateMachine(this); QState *s1 = new QState(mStateMachine); QState

I'm using Qt framework which has by default non-blocking I/O to develop an application navigating through several web pages (online stores) and carrying out different actions on these pages. I'm "mapping" specific web page to a state machine which I use to navigate through this page. This state machine has these transitions; Connect, LogIn, Query, LogOut, Disconnect and these states; Start, Connecting, Connected, LoggingIn, LoggedIn, Querying, QueryDone, LoggingOut, LoggedOut, Disconnecting, Disconnected Transitions from *ing to *ed states ( Connecting->Connected ), are due to LoadFinished

I have two widgets that can be checked, and a numeric entry field that should contain a value greater than zero. Whenever both widgets have been checked, and the numeric entry field contains a value greater than zero, a button should be enabled. I am struggling with defining a proper state machine for this situation. So far I have the following: QStateMachine *machine = new QStateMachine(this); QState *buttonDisabled = new QState(QState::ParallelStates); buttonDisabled->assignProperty(ui_->button, "enabled", false); QState *a = new QState(buttonDisabled); QState *aUnchecked = new QState(a);

In another question you tell me to use QStateMachine. I'm new to Qt and it's the first time i use the objects so I make a lot of logical mistake, so using QStateMachine it's a big problem... It's the only way to do thath ? I try to explain my program: I want to create a card's game and in the previous version I've used an old graphics library with this sequence of commands: -> print cards on the scene -> wait for a mouse input (with a do-while) -> if(isMouseClick(WM_LBUTTONDOWN)) -> if(mouse position is on the first card) -> select that card. So i wish to do the same thing with QGraphics. In
