Using Offsets

After specifying constraints for the various edges, you can add or subtract pixels, for example, to leave space between two labels. The following code example shows how to use one of the offset values followed by an integer to specify the number of pixels to offset the edge.

   CONTROL "Hello", IDC_CTRL_HELLO,"APC_Label:",
      ASFC_ALIGN_LEFT|ASFC_ALIGN_SINGLELINE
   BEGIN
      ...
      FA_LEFT_OFFSET, 2   // Offset the left edge by two pixels.
      FA_RIGHT_OFFSET, 2  // Offset the right edge by two pixels.
   END

Note You could also use FA_HORIZONTAL_OFFSET, 2.
