Scrolling using mouse wheel (or scroll arrow buttons) in "Options > Fonts & Colors > Syntax > Preview area" (select language "Yaml") is very slow (1-3 pixel) because a `JPanel` is used as view in a `JScrollPane`. Since `JPanel` does not implement the `javax.swing.Scrollable` interface, the scrollpane uses a unit increment of 1. So clicking scroll arrow arrows (or rotating mouse wheel one tick) scrolls only 1-3 pixel (depending on OS and scroll amount specified in OS settings). This fix simply sets unit increment to 10. This is similar to other code in NB: https://github.com/apache/netbeans/search?q=setUnitIncrement This affects all Lafs. For FlatLaf, this also improves smooth scrolling (using trackpad) reported here: https://issues.apache.org/jira/browse/NETBEANS-5025 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
