如何使用NCurses阻止C ++中的某些键

Question

I'm new to C/C++ and I'm making a simple text user interface with NCurses .

Whenever I scroll up/down with the mouse wheel, or press arrow keys, the console echos characters like:

"[[A^[[C^[[B^[[D" 

to show me that I've pressed the keys.

I would like to stop these from echoing and only echo basic keys (punctuation and letters).

Here is my main loop. I basically want it to be my own console with commands that I create.

string input;
char inputArr[80];
while (input != "q" && input != "quit" && input != "exit" && input != "leave") {
    printw(" > ");
    refresh();
    getstr(inputArr);
    input = inputArr;
    if (input.substr(0, 3) != "someCommand") {
        printw("\n ~ %s\n\n", inputArr);
        refresh();
    } else
        execCmd();
}
quit();

For the most part I believe it is C++ but I do have a C function (that uses libCurl).

Also, is there no cleaner way to read in strings with NCurses? I dont really like using char arrays (I'm used to Java).

Call noecho() somewhere close to initscr() .

This will avoid clobbering your screen with unwanted input. If you want your users to see what they type later on, you will need to call echo() before, however.
