Updates form User Interface State as needed
procedure UpdateUIState(CharCode: Word);
__fastcall UpdateUIState(Word CharCode);
UpdateUIState is called in component code to ensure that the User Interface State is consistently updated. User Interface State determinates whether keyboard accelerators and focus indicators are hidden or shown. A control should call UpdateUIState whenever it receives a keyboard event that might invalidate the User Interface State. CharCode is the virtual key code of the keyboard event.
