Ncurses - Getting character of wanted cell? [SOLVED]

Scionar · 2011-04-05 19:29:01

Hi!

I have been started learning C++ and again trying to do something funny with ncurses. I have now problem which I could solve different ways, but of course if there is this easy way I would use it.

Is there any functions in ncurses which tells which character is in wanted cell? Example if I have character # in cell 6,10 how can I prove that?

If there is something what you didn't understand, just ask. English is not my native language, so there can be some misunderstandings.

I suggest you:

man 3 inch
man 3 inchstr
man 3 in_wch
man 3 inwstr

Taking your example (assume the target window is stdscr):

char ch = mvinch(10, 6) & A_CHARTEXT;

I didn't test it but it should be something like that.

(not native english too so I'm sorry if I made any mistakes).

Yeah! That mvinch-function worked well. Thanks.

I didn't add that "& A_CHARTEXT" to the end, but it worked anyway. I tried to add it anyway to the end, but it didn't make difference.

Let's play that we have # at 6,9:

if (mvinch(6,9) == '#')  {
     implementation
}

This executes the implementation.

I suggest you to keep "& A_CHARTEXT" in place. If you read the man page it's clear, the function return the *chtype* at the given position, it doesn't return a character. An attribute have 3 elements, the character, the attributes and the color. If you add colors in the future the value of chtype will not be '#' but '#' | YOU_COLOR_VALUE.
