/**
 * @brief The WiresharkFileDialog class
 *
 * Qt <= 5.9 supports setting old (Windows 8.1) per-monitor DPI awareness
 * via Qt:AA_EnableHighDpiScaling. We do this in main.cpp. In order for
 * native dialogs to be rendered correctly we need to to set per-monitor
 * *v2* awareness prior to creating the dialog.
 * Qt doesn't render correctly when per-monitor v2 awareness is enabled, so
 * we need to revert our thread context when we're done.
 * The class functions below are simple wrappers around their QFileDialog
 * equivalents that set PMv2 awareness before showing native dialogs on
 * Windows and resets it afterward.
