    Question QLabel based Custom Widget contains QMovie to support GIF Rendering

    Hi,

    I have a custom widget based on QLabel, which it includes the QMovie.

    I did overwrite the paintEvent(QPaintEvent* event).

    Added QMovie->setFileName(GifFilePath); and QLabel->setMovie(QMovie); in the paintEvent function.

    However, QMovie->isValid() returns false for me. I use isValid() as validation before I start the QMovie.

    Why my QMovie is not valid?

    Thanks in advance.

    first of all you should not set the movie in paintevent.. there is not need for overriding the paintevent..
    secondly can we see the code? QLabel->setMovie(QMovie) will not compile for me

    Hi @MrDeath, thanks for helping me again in another thread here.

    Qt Code:
    1. void QLabel::setMovie ( QMovie * movie )
    To copy to clipboard, switch view to plain text mode 

    So, I should not put it in paintEvent? I would like to show / hide it when user do something.
