How to splash screen a gif video

[mrjj]

Hi
You can use QMovie

QMovie *movie = new QMovie(":/images/other/images/16x16/loading.gif");
QLabel *processLabel = new QLabel(this);
processLabel->setMovie(movie);
movie->start();

@mrjj said in How to splash screen a gif video:

QMovie *movie = new QMovie(":/images/other/images/16x16/loading.gif");
QLabel *processLabel = new QLabel(this);
processLabel->setMovie(movie);
movie->start();

previously i used this :

QSplashScreen *splash = new QSplashScreen;

splash->setPixmap(QPixmap("C:/Users/data/Documents/untitled14/giphy.gif"));
splash->show();

QTimer::singleShot(2500,movie,SLOT(close()));
QTimer::singleShot(2500,&w,SLOT(show()));

this should run when an application icon is clicked .

@ManiRon
QLabel will not show animated gif unless setMovie is used.

@mrjj

Now i am trying like this in my main.cpp file :

QMovie *movie = new QMovie("C:/Users/data/Documents/untitled14/giphy.gif");
QLabel *processLabel = new QLabel(&w);
processLabel->setMovie(movie);
movie->start();

QTimer::singleShot(2500,movie,SLOT(stop()));
QTimer::singleShot(2500,&w,SLOT(show()));

@ManiRon
hi
seems fine and i assume its in main.cpp ?

[ManiRon]

@mrjj yes sir

[ManiRon]

@mrjj when i ran this i got QObject::connect: No such slot QMovie::close() in main.cpp:23 this error

[mrjj]

Hi
well, it means QMovie do not have a close slot.
it has

so maybe you mean stop ?

[ManiRon]

@mrjj yes i changed it and ran the program but still the gif is not playing and the mainwindow is displaying directly

[ManiRon]

@mrjj the gif is playing but it plays at the top right corner of the mainwindow

[JohanSolo]

@ManiRon This means you didn't put properly the QLabel in a layout or set it as the central widget.

[ManiRon]

the indicated part is the loading gif but it comes in the mainwindow

[mrjj]

@ManiRon
Hi
Please show the complete main.cpp code

[ManiRon]

@JohanSolo my doubt is i want to display the loading gif first then after a small amount of time the mainwindow. I have added the code which i have used kindly can u see that and point out if there is any mistake sir.
Thanks.

@mrjj

This is the main.cpp full code sir

QApplication a(argc, argv);
MainWindow w;

QMovie *movie = new QMovie("C:/Users/data/Documents/untitled14/200w.gif");
QLabel *processLabel = new QLabel(&w);
processLabel->setMovie(movie);
movie->start();

QTimer::singleShot(5000,movie,SLOT(stop()));
QTimer::singleShot(2500,&w,SLOT(show()));

@ManiRon

QLabel *processLabel = new QLabel(&w); << u set main win as parent so its shown inside.
if its to be like window BEFORE mainwin comes, use null as parent.

[ManiRon]

@mrjj Now i should give as QLabel *processLabel = new QLabel(NULL); ?

[ManiRon]

@mrjj i should display the gif file then the mainwindow, is that possible sir?

[mrjj]

@ManiRon

• QLabel *processLabel = new QLabel(NULL); ?
  Yes. will make it window.'

Yes, it should be.
Just dont call w.show() before u want to.
