/**
* @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 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.
