Placing textfields from for loop

Hello

I have a little problem. I am making a simple text menu and i am generating some textfields along the x axes and placing them like this.

_menu.x = i * 90;

The problem is that not all of the textfields has the same length and therefore they are not placed with the same spacing.

I want to make 90 pixels of space between each textfield, but how do i do that?
