Hi all,

I'm doing a lot of messing around with strings, and I'm trying to find the point in a string at which a change was made by the user.

What I really need is a command like GetEditBoxCursorPosition() - can't believe that's not there!

I've tried comparing the string from the edit box and the string stored in a variable, to locate the character index at which they become different, but this doesn't work if the strings contain more than one occurrence of the same letter together.

e.g.

Old string: abcdddddddefgh
New string: abcddddddddefgh

Impossible to tell where the extra 'd' was added!

Can anyone think of a solution?

Thanks,

James

You really need that missing command!

How about this...

I was trying to think of a way to encode a second copy to compare against, but I don't think it is possible.

Thanks BatVink and Markus. I've been racking my brains to think of a way to do it, and the only thing I've come up with is Markus' suggestion of writing my own edit box.

That's problematic in itself - if I want to release my app on iOS and Android, my edit box would have to behave itself on those OSes as well. I could spend weeks on that!

Paul (if you're reading this!) please would you add that missing command?! I'm a bit stuck without it!

it is possible to track the key input.
track the length of the word then every time the left or right key is pressed you can have a variable telling you the position of the cursor...(I think)
eg if you type a 5 letter word, then press the left key once, you will know that the cursor is at position 4 by taking the word length and subtracting the amount of times the left key has been pressed.

The problem is that you can change the cursor position with touch/mouse. At that point you can't retrieve the position.

one idea i have is to overwrite the position with your value each sync
but i don't know if this works well.
SetEditBoxCursorPosition ( index, pos )

@Rickynzx
do not forget you can move the cursor with mouse hit or touch.
