+/**
+ * @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.
