Question regarding GuiTextEditCtrl

Basically I am working on a trade system.
I want to make it so that if you enter a character that isn't a number it will remove it. I have made the detection weather it is a number or not but how would I remove the last character of the textedit control?
I have tried a few things, such as:

PHP Code:


		
			
Trade_MyGralats.text.length() -= 1;
Trade_MyGralats.text.size() -= 1;
Trade_MyGralats.text -= 1;

But none of them work, Thanks in advanced.
I was also thinking maybe it would have something to do with .pos() Not sure though.
Maybe this is an idea for a future improvement for text controls.

PHP Code:


		
			
allowedcharactersonly = true;
allowedcharacters= { "a", "b", "c" };

PHP Code:


		
			
Trade_MyGralats.text.length() -= 1;
Trade_MyGralats.text.size() -= 1;

These make no sense, the return value of a function is not a variable.

PHP Code:


		
			
Trade_MyGralats.text -= 1;

text is a string, not a number, so this isn't going to work either.

PHP Code:


		
			
Trade_MyGralats.text = Trade_MyGralats.text.substring(0, Trade_MyGralats.text.length() - 1);

substring is the key. Probably you'd be better off just saving a copy of the old string (before letters were added) and then changing the text back to the old string if they enter a letter. Right now someone could just enter a letter anywhere but the end of the string and it wouldn't fix this.

Ahok. So when there is a keydown if they don't press a letter save temp.text, then if they press a letter change the text to temp.text, shoulda thought of that, thanks.

the real solution though is to just have the guitexteditctrl use its own profile and change profile.numbersonly to true.

O_o That seems a lot simpler.
Does it allow to copy and paste though? Because I didn't want to allow copy and pasting.
