Constant Summary

ARGNONE =

MSGTYPE

This is a module to collect constants of Windows message's argument type. These constants decide an argument list for message handler. The point is how to use lParam and wParam which are Integers.

Constants

--- ARGNONE No use of wParam and lParam. The handler don't have arguments. --- ARGINT lParam is the argument of handler. The handler is defined as a type of self_handler(lParam) --- ARGSTRUCT lParam is a pointer to structured data. The handler's argument is decided by that structure. --- ARGSTRING lParam is a char* pointer. The handler is defined as a type of self_handler(String) --- ARGWINT wParam is for the argument of handler. The handler is defined as a type of self_handler(wParam) --- ARGLINT Same as ARGINT --- ARGINTINT lParam and wParam are for the argument. The handler is defined as a type of self_handler(wParam,lParam) --- ARGINTINTINT lParam and wParam are for the arguments, and lParam will be devided into two integers of lo-word of lParam and hi-word of lParam. The handler is defined as a type of self_handler(wParam,LO_lParam,HI_lParam) --- ARGLINTINT lParam is for the argument, and lParam will be devided into two integers of lo-word of lParam and hi-word of lParam. The handler is defined as a type of self_handler(LO_lParam,HI_lParam) --- ARGINTSTRUCT wParam and structured lParam is for the arguments. The handler is defined as a type of self_handler(wParam, ...*struct...) --- ARGINTSINTSINT Almost same as ARGINTINTINT. But that two lParam integers are dealed as signed integers. --- ARGPASS The argument is an instance of SWin::MSG. The handler is define as a type of self_handler(msg).
