Chaining multiple UI with QStatemachine

[dlewin]

thanks?
Well ... ok I forget i.

what I don't see the way is : "it receives all pointers,"

[anda_skoa]

What does your code look right now?

How and where do you create the instances of these UIs?

Cheers,

To simplify the explanations I'd say I work by validating function parts, that are :
* using a QStatemachine :

QState *s1 = new QState();
    QLabel *label1 = new QLabel("Original state ");
    QState *s2 = new QState();
    QState *s3 = new QState();
 
    s1->assignProperty(&button, "text", "Click me"); //Property is assign only when state-machine is started.
 
    machine.addState(s1);
    machine.addState(s2);
    machine.addState(s3);
    machine.setInitialState(s1);
 
    // Definition de l'enchainement des états
    s1->addTransition(&button, SIGNAL(clicked()), s2);
    s2->addTransition(&button, SIGNAL(clicked()), s3);
    s3->addTransition(&button, SIGNAL(clicked()), s1);
 
    // Definition de l'action des états
    s1->assignProperty(label1, "text", "Splash screen");
    s2->assignProperty(label1, "text", "1 Menu");
    s3->assignProperty(label1, "text", "3 Maintenance");
 
    machine.start();
 
    layout->addWidget(&button);
    layout->addWidget(label1);

QState *s1 = new QState();
    QLabel *label1 = new QLabel("Original state ");
    QState *s2 = new QState();
    QState *s3 = new QState();

    s1->assignProperty(&button, "text", "Click me"); //Property is assign only when state-machine is started.

    machine.addState(s1);
    machine.addState(s2);
    machine.addState(s3);
    machine.setInitialState(s1);

    // Definition de l'enchainement des états
    s1->addTransition(&button, SIGNAL(clicked()), s2);
    s2->addTransition(&button, SIGNAL(clicked()), s3);
    s3->addTransition(&button, SIGNAL(clicked()), s1);

    // Definition de l'action des états
    s1->assignProperty(label1, "text", "Splash screen");
    s2->assignProperty(label1, "text", "1 Menu");
    s3->assignProperty(label1, "text", "3 Maintenance");

    machine.start();

    layout->addWidget(&button);
    layout->addWidget(label1);

To copy to clipboard, switch view to plain text mode 

------------------------------------------------------------

* I aim to use this code into whatever allows me to do what I want to, like any Qtcreator application wizard will generate :

I use the main (but not sure this is the best idea) :

SplashScreen *SScreen = new SplashScreen ();
 
  SScreen ->show();

SplashScreen *SScreen = new SplashScreen ();

  SScreen ->show();

To copy to clipboard, switch view to plain text mode 

then in MainWindow I use :

void MainWindow::Splash_Timerout()
{
    //this->show();
  Frm_Warning_Sourceinvalide *Warning_window = new Frm_Warning_Sourceinvalide();
  Warning_window->show();
}

void MainWindow::Splash_Timerout()
{
    //this->show();
  Frm_Warning_Sourceinvalide *Warning_window = new Frm_Warning_Sourceinvalide();
  Warning_window->show();
}

To copy to clipboard, switch view to plain text mode

Some options:

s1->assignProperty(splashScreen, "visible", true);
s2->assignProperty(warningWindow, "visible", true);
 
// and a transition that triggers s1 -> s2 when the slash closes/times out.

s1->assignProperty(splashScreen, "visible", true);
s2->assignProperty(warningWindow, "visible", true);

// and a transition that triggers s1 -> s2 when the slash closes/times out.

To copy to clipboard, switch view to plain text mode 

connect(s1, SIGNAL(entered()), someReceiver, SLOT(showSplash()));
connect(s2, SIGNAL(entered()), someReceiver, SLOT(showWarning()));

connect(s1, SIGNAL(entered()), someReceiver, SLOT(showSplash()));
connect(s2, SIGNAL(entered()), someReceiver, SLOT(showWarning()));

great indeed this is better.
Then : I still need to update the S1 transition from MainWindow when it's finished after 10s

[anda_skoa]

That's what I wrote, no?

// and a transition that triggers s1 -> s2 when the slash closes/times out.

// and a transition that triggers s1 -> s2 when the slash closes/times out.

I meant : by code.

Thanks

[anda_skoa]

I don't understand what you mean.

Of course adding a transition is done by code, how else would you do it?

[dlewin]

It's ok.

I would paraphrase Magrite elsewhere :

// and a transition that triggers s1 -> s2 when the slash closes/times out.

"this is not a code"
