The `reducedData` preference instructs applications to minimize internet traffic, as users might be on a metered network or a limited data plan.
This corresponds to the following OS settings: Windows: Settings -> Network and Internet -> Ethernet/WiFi -> Metered connection macOS: Settings -> Network -> Ethernet/WiFi -> Network Settings -> Low data mode Ubuntu: Settings -> Network -> Wired/WiFi -> Metered connection Change notifications work consistently on Windows and macOS. On my Ubuntu 24 system, the GIO `network-changed` signal is not sent when I only toggle the "metered connection" flag in network settings (and there's no signal specifically for low-data mode). The new value is only picked up when the connection changes by coming offline or going online. ------------- Commit messages: - error message tweak - add macOS implementation - add linux implementation - Implementation of reducedData Changes: https://git.openjdk.org/jfx/pull/1656/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1656&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8343398 Stats: 250 lines in 17 files changed: 211 ins; 28 del; 11 mod Patch: https://git.openjdk.org/jfx/pull/1656.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1656/head:pull/1656 PR: https://git.openjdk.org/jfx/pull/1656
