Qt-Advanced-Docking-System

Updated CFloatingDockContainer::closeEvent() function to delete all dock widgets with DockWidgetDeleteOnClose flag set

Avoid calling XCB functions under non-XCB Linux platform (#405)

fix(issue-350): on RedHat/CentOS, sometimes there will be one more move event after user release their mouse which will cause the floating overlay can not be hide. Here we use the WindowActivate and WindowDeactivate event to check whether user release their mouse. (#401)

Fixed examples/sidebar bug
