I worked on a piece of code from looking at examples and this is the
best I could come up with. Most of it is sudo-code to give you an idea
of what I want to do.
%override wxLua_function_timer
// %function timer(unsigned int msec, int* exitflag)
static int LUACALL wxLua_function_timer(lua_State *L)
{
wxLuaState wxlState(L);
int mSec = 0;
int* exitFlag = NULL;
timer* returns;
// get the lua passed in parameters
mSec = wxlState.getInt(1);
exitFlag = wxlState.getIntPrt(2);
// call timer constructor
returns = new timer(mSec, exitFlag, NULL);
// push the result datatype
wxlState.PushUserDataType(s_wxluatag_timer, returns);
// return the number of parameters
return 0;
}
%end
Thanks for your time.
