16  * @brief The WiresharkFileDialog class
17  *
18  * Qt <= 5.9 supports setting old (Windows 8.1) per-monitor DPI awareness
19  * via Qt:AA_EnableHighDpiScaling. We do this in main.cpp. In order for
20  * native dialogs to be rendered correctly we need to to set per-monitor
21  * *v2* awareness prior to creating the dialog.
22  * Qt doesn't render correctly when per-monitor v2 awareness is enabled, so
23  * we need to revert our thread context when we're done.
24  * The class functions below are simple wrappers around their QFileDialog
25  * equivalents that set PMv2 awareness before showing native dialogs on
26  * Windows and resets it afterward.
