QSlider handle is being hidden when changing the background of the groove

Question

I\'m trying to change the background image of the grove and set an image on the handle. While doing so, I ran into a situation where the handle (which works) is being covered b

Answer 1

It seems to be a bug, it seems that the handle is resized to a size that makes it invisible, but if it can move with some difficulty. The last statement I checked with the following code.

 connect(mySlider, &QSlider::valueChanged, [=](int value){
     qDebug()<<value;
 });

It is advisable to place a width and height, by example:

mySlider->setStyleSheet("QSlider::groove:horizontal {background-color:yellow;}"
                        "QSlider::handle:horizontal {background-color:blue; height:16px; width: 16px;}");
