Git commit 892c5a27b427b63b8faa4cd5f92141040fd0fcd1 by Nate Graham, on behalf of Eugene Popov. Committed on 03/03/2022 at 21:17. Pushed by ngraham into branch 'master'. SystemMonitor: Port to KMainWindow Currently, KSystemActivityDialog is derived from QDialog and therefore has several limitations: * it doesn't save and restore its size and position * it doesn't respect Window Placement settings (it always opens in the center) Porting it to KMainWindow removes these limitations and saves the user from creating window rules to get around them.
