Wt

Hey,

I created a WStackedWidget, and It works properly without animation, but when I try to add a simple Fading animation, the stack's widgets don't change.

Please tell me what am I doing wrong, or if you have the same problem when you try to run this in your browser.

Here is the full code : compile with ./app ---docroot . ---http-address 0.0.0.0 ---http-port localhost:portNumber

#include <Wt/WApplication>
#include <Wt/WStackedWidget>
#include <Wt/WContainerWidget>
#include <Wt/WPushButton>
#include <Wt/WText>
#include <Wt/WAnimation>

class MyContainer : public Wt::WContainerWidget
{

    public :
        MyContainer();

        void switchWidget();
    private :
        Wt::WStackedWidget* theStack;
        Wt::WPushButton* theButton;
};

MyContainer::MyContainer()
    : WContainerWidget(),
      theStack(new Wt::WStackedWidget(this)),
      theButton(new Wt::WPushButton("push me", this))
    {   
        theStack->addWidget(new Wt::WText("Widget number 1"));
        theStack->addWidget(new Wt::WText("Widget number 2"));
        theStack->addWidget(new Wt::WText("Widget number 3"));
        theStack->addWidget(new Wt::WText("Widget number 4"));

        // When I add the following piece of code, It doesn't work
         Wt::WAnimation animation(Wt::WAnimation::Fade,
                Wt::WAnimation::Linear, 250);
        theStack->setTransitionAnimation(animation,true);
       //------------

       theButton->clicked().connect(std::bind([&](){
                    this->switchWidget();
                    }));
    }    

void MyContainer::switchWidget() {

    int current = theStack->currentIndex();
    if(current!=3) theStack->setCurrentIndex(current+1);
    else theStack->setCurrentIndex(0);

}   

class Napp : public  Wt::WApplication
{                   

    public :
        Napp(const Wt::WEnvironment &env);
};

Napp::Napp(const Wt::WEnvironment &env)
    : WApplication(env)
{
    this->root()->addWidget(new MyContainer());
}

Wt::WApplication* createApp(const Wt::WEnvironment &env)
{

    return new Napp(env);
}

int main(int argc, char** argv)
{   
    return WRun(argc,argv,&createApp);
}
