PyQt5 – Skin to Bar of Progress Bar

In this article we will see how to set the skin to the bar of progress bar. Skin is basically a background image but it adjust it self to the size of bar of progress bar. Below is the representation of bar of progress bar with background image and bar of progress bar with skin.

In order to do this we have to change the CSS style sheet code of bar of progress bar which is used with the setStyleSheet method, below is the style sheet code.

QProgressBar
{
border :1px solid black;
}
QProgressBar::chunk
{
border-image : url(skin.png);
}

Below is the implementation.
