Hi Xavi,
two main differences exist:
1. With I_INFIELD_2 and I_INFIELD_3 you can input also Array values
------------------------------------------------------------------------
instead
I_INFIELD "test" , x,y,width,height (don't work properly, if "test" is an array!!)
you can write
I_INFIELD test[2][4], x,y,width,height, ...
2. With the "method" you can create special input controls
-------------------------------------------------------------
I_INFIELD_3 "name", x, y, width, height [,
method, picture_name,
images_number,
rows_number, cell_x, cell_y,
image_x, image_y,
expression_image1, text1,
...,
expression_imagen, textn, alignment]
[I_TOOLTIP tooltiptext]
see special_controls.png
