Summary0034752: Qt - TCalendar does not receive LM_KEYDOWN and LM_KEYUP when pressing arrow keys (up, down, left, right).
DescriptionIn Qt, TCalendar does not receive key messages when a cursor (arrow - left, right, etc.) key gets pressed.
Unlike Qt, Gtk2 and Win32/64 do receive these.

I'm attaching a test application.
Steps To ReproduceTake a look at attached application. Compile with Qt widgetset and start.

The application shows that:
- WindowProc in TCalendar never receives LM_KEYDOWN and LM_KEYUP when an arrow key is pressed.
- as a consequence, events OnKeyDown and OnKeyUp do not work with arrow keys.

When compiled with Gtk2, everything works, as well as in Windows (win widgetset).

Tested in Linux Mint 18.3 64-bit Xfce (Qt4 and Gtk2 ws) and Windows 8 (win ws).
TagsNo tags attached.
