On changing LookAndFeel of JTabbedPane, it resets the focus of the child tabs to starting child tab. That is, if a JTabbedPane has say 10 tabs and we select the 10th tab and then we change the L&F, the focus is shifted to Tab0 even though the selected tab is still at 10th tab.
This is because when we switch L&F, `installUI ` will reset the `focusIndex ` https://github.com/openjdk/jdk/blob/3481252ced7c06c44154ceccc56b12cfd9a490c3/src/java.desktop/share/classes/javax/swing/plaf/basic/BasicTabbedPaneUI.java#L285-L290 which needs to set the proper focus by calling `scrollRectToVisible ` to selected tab which is done in this fix. ------------- Commit messages: - jcheck - jcheck - 4459231: Focus of JTabbedPane(with Scrollable tablayout) changes on change in LookAndFeel Changes: https://git.openjdk.org/jdk/pull/28571/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=28571&range=00 Issue: https://bugs.openjdk.org/browse/JDK-4459231 Stats: 119 lines in 2 files changed: 119 ins; 0 del; 0 mod Patch: https://git.openjdk.org/jdk/pull/28571.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/28571/head:pull/28571 PR: https://git.openjdk.org/jdk/pull/28571
