SnapScroll ​

Package com.realeyez.trademart.gui.components.scroll

For scrolling through panels of equal sizes wherein when you scroll vertically, you want to snap to the next panel, the SnapScroll panel class should be used. This behavior is comparable to scrolling through tiktok or youtube shorts. All you need to do is create an instance of this and provide it a ScrollView to apply the scroll snapping to.

TIP

The SnapScrollH is a horizontal version of this class.
