It is not possible to select all files on press of Ctrl+A in JFileChooser for GTK LAF where as all folders can be selected. In native side on press of Ctrl+A, able to select all files as well as folders.
Proposed fix is to enable `multiselection `property by default for JFileChooser in GTK LAF to mimic native side behavior. An automated test case is implemented and tested in CI. CI job links are attached in JBS. ------------- Commit messages: - Select all files on CTrl+A fix Changes: https://git.openjdk.org/jdk/pull/11627/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=11627&range=00 Issue: https://bugs.openjdk.org/browse/JDK-4912623 Stats: 170 lines in 2 files changed: 170 ins; 0 del; 0 mod Patch: https://git.openjdk.org/jdk/pull/11627.diff Fetch: git fetch https://git.openjdk.org/jdk pull/11627/head:pull/11627 PR: https://git.openjdk.org/jdk/pull/11627
