I'm currently using a function to stop inkey when I hit the left mouse button.
However, this does not properly store the string as it would if I hit enter or tab.
For example, if I were to type "ggg" and then end this prematurely:
str_cpy(gonline_uname," ");
result = inkey(gonline_uname); //- enter online name
The resulting string would be "ggg____________"
Whereas the underline is actual spaces(this forum wont let me display spaces there??). However, if I hit enter instead, it would be:
"ggg"
This would be fine if I could find a way to know how to trunc the spaces, but I do not. Could we have inkey_active = 0; act the same way as if we ended the inkey operation normally? Thanks.

Seconded, i really need this too.
edit: for me the string always(!) has "spaces" at the end, even if the user presses enter.

Or you can just trim off the end spaces.
int str_rtrim(STRING* input)
{ int trunc, pos; for(pos=str_len(input)-1; pos>0; pos--)
{ if((input.chars)[pos]!=32)
{ str_trunc(input, (trunc=str_len(input)-pos-1));
break;
} }
return(trunc);
}
This function trims off any trailing spaces (on the right-hand end of the string), and it returns the number of trimmed spaces if you want to know...

Basically, it starts at the LAST character of the total string, and checks to see if it is a space(==32).
If it is NOT a space-character, it truncates everything 'beyond' this point, and exits the loop.
If it IS a space-character, it loops over to checks the next character back, et al.
note: variable "pos' is which byte it is currently checking,
and variable 'trunc' gets set to how many characters got truncated.
[EDIT] Ive just changed to snippet so the variable names are more descriptive...
