Is there a loading widget?

qwe3

Hi,

I need to widget, which will be use, when the application will be start. So this is a "loading / waiting widget". I know there is a QProgressBar, but I don't know how long will be application started. I need something like GIF, where we have loop:

How can I do that?

Hi,

It seems you are looking for QSplashScreen.

@SGaist Thank you, but I find something, what I'm looking for:

    QProgressBar *bar = new QProgressBar(this);
    bar->setGeometry(50,50,300,40);
    bar->setTextVisible(false);
    bar->setStyleSheet("QProgressBar::chunk {    background-color: #2196F3; width: 10px;  margin: 0.5px;}");
    bar->setMinimum(0);
    bar->setMaximum(0);

Now I have exactly, what I want, but I have 2 other problems:

how to change speed of move blue rectangles in this progressBar?
how to change the amount of blue rectangles in progressBar? I know that I can change width in styleSheet to 20 px, but I would like to have width = 10 px, but I would like to change percent of blue rectangles to 20% in progressBar.

AFAIK you can't
AFAIK the number is dependent on the width of the bar and the number of steps.

If you don't like the granularity of the QProgressBar then you'll have to design a custom widget that does what you need. Looks like the granularity of progress is fixed or precacluted by the stock widget.
