Member Function Documentation

void os::DropdownMenu::DropdownTextView::KeyDown ( const char *  pzString, const char *  pzRawString, uint32  nQualifiers  )

virtual

Description:

Overload this member if your view need to handle keyboard input. This member is called to allow the view to handle M_KEY_DOWN messages. The most common members are exctracted from the message and passed as parameters but you might need to obtain the raw message with os::Looper::GetCurrentMessage() and find some members yourself if you the data you needed are not passed in.

For example if you need the raw key-code for the pressed key you will have to lookup the "_raw_key" member from the message.

Parameters

pzString	String containing a single UTF-8 encoded character. This is the character generated by the pressed key according to the current keymap accounting for any qualifiers that might be pressed.
pzRawString	Same as pzString except that the key is converted without accounting for qualifiers. Ie. if 'A' is pressed while pressing <SHIFT> pzString will contain 'A' and pzRawString will contain 'a'.
nQualifiers	Bitmask describing which qualifiers that was active when the key was pressed.
