PyQt5 QScrollBar – Getting Range Changed Signal
In this article we will see how we can get the range changed signal of QScrollBar. QScrollBar is a control that enables the user to access parts of a document that is larger than the widget used to display it. Slider is the scroll-able object inside the bar. By default value range from 0 to 99. Value is basically depend upon the slider position, scroll bar value changes according to the position of the slider, value increases when slider goes down and decreases when slider moves up. It can be programmatically set with the help of
setValue method. Range is basically a combination of minimum and maximum value which can be set with the help of
setRange method. This signal is emitted when the slider range has changed, with min being the new minimum, and max being the new maximum.
In order to do this we will use
rangeChangedmethod with the scroll bar object.
Syntax : scroll.rangeChanged.connect(method)
Argument : It takes method as argument
Return : It returns None
Below is the implementation
