How to splash screen a gif video

[mrjj]

@ManiRon
HI
Thats the internal aligment :)

I assume you mean to center window onthe screen / desktop
https://wiki.qt.io/How_to_Center_a_Window_on_the_Screen

[ManiRon]

@mrjj its coming like this when i use code from the above mentioned link

[mrjj]

@ManiRon
you do that on label ?

anyway, you should set both alignments so movie is in center

[ManiRon]

@mrjj

This is my code

processLabel->setGeometry(
QStyle::alignedRect(
Qt::LeftToRight,
Qt::AlignCenter,
processLabel->size(),
qApp->desktop()->availableGeometry()

[mrjj]

@ManiRon
ok.
well u need to center the movie also or
set size of label to size of movie.

[ManiRon]

@mrjj

i have to do both sir .

[mrjj]

@ManiRon
well to be on safe size u can do that.
use resize to size label to width, height of movie

[ManiRon]

@mrjj not getting your point

[ManiRon]

@mrjj

QMovie *movie = new QMovie("C:/Users/data/Documents/untitled14/200w.gif");
QLabel *processLabel = new QLabel(NULL);
processLabel->setMovie(movie);
movie->start();
processLabel->setWindowFlags(Qt::FramelessWindowHint);
processLabel->setGeometry(
QStyle::alignedRect(
Qt::RightToLeft,
Qt::AlignCenter,
processLabel->size(),
qApp->desktop()->availableGeometry()
));
processLabel->show();

This Is my current code

[mrjj]

@ManiRon
you can use
processLabel->resize( some width, some height )
and i told u how to center movie in label already

[ManiRon]

@mrjj

Is this the one to center the movie

processLabel->setAlignment(Qt::AlignCenter);

for example,
I added this in my code,

processLabel->resize(100,100);
error: invalid use of void expression
)
^

It showed this error

[mrjj]

@ManiRon
yes.
its AlignCenter = AlignVCenter | AlignHCenter

[ManiRon]

@mrjj after giving this also the gif is not aligining

[mrjj]

@ManiRon
ok. not sure what goes wrong then.

[ManiRon]

@mrjj oh

[mrjj]

@ManiRon
but if u just resize label, is movie not in the center then ?

[ManiRon]

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

resize

tried to resize but it throwed error

processLabel->resize(100,100);
error: invalid use of void expression
)
^

It showed this error

[mrjj]

@ManiRon
please show more of the code.
it works here so error is due to do it in odd place or something else i cant see.

Hi
Your code works just fine ?

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;

QMovie *movie = new QMovie(":/kTTdW2l.gif");
QLabel *processLabel = new QLabel(nullptr);

processLabel->resize(200,200);  // to make sure its large enough

processLabel->setMovie(movie);
processLabel->setWindowFlags(Qt::FramelessWindowHint);
processLabel->setAlignment(Qt::AlignCenter);
processLabel->setGeometry(  QStyle::alignedRect(Qt::LeftToRight,Qt::AlignCenter,processLabel->size(),qApp->desktop()->availableGeometry())         );

movie->start();
processLabel->show();

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

return a.exec();
}
