Buttons initialization ,array of strings problem

[TangerineDreamer]

Hi,bodmer or someone else can answer me :)

I'm trying to initialize an array of strings to give labels to my buttons like this:

char keyMoreLabel[] = {"new line","spacing"};

i had always an error,so i looked over the arduino reference and the solution that they give:

char *keyMoreLabel[] = {"new line","spacing"};

is an array of pointers and it compiled good,but the buttons don't respond to the touch even if they
are well drawed.
Why and when should i use pointers to initialize a char or an an array of strings even if i will not use
the pointers?

So...i finally answer myself, the arduino reference site didn't show all the options and a clear answer was hard to collect all
over the net.

char *keyMoreLabel[] = {"new line","spacing"}; // one dimension pointer char arrays
const char *keyMoreLabel[] = {"new line","spacing"};
char *keyMoreLabel[2] = {"new line","spacing"};

char keyMoreLabel[][10] = {"new line","spacing"}; //two dimension char arrays with room left on second dimension
char *keyMoreLabel[2][10] = {"new line","spacing"};

String keyMoreLabel[] = {"new line","spacing"}; //one dimension string array
String keyMoreLabel[2] = {"new line","spacing"};

This helped myself:

they talk also about vector class and array class,but i didn't take these options.
