void = SetBoxHor(nFixedUnits)
the XYWH measurements palettes of QuarkXPress and InDesign
This macro function is used to specify the horizontal position of the textbox that contains the macro token as nFixedUnits, without changing the box's size.
nPos = SizeMm(10000) // 10 mm or about 0.25 inches
SetBoxHor(nPos)
This macro function is a simultaneous call to SetBoxLeft and SetBoxRight ensuring that the width of the box remains the same all through the resizing and avoid potential occurrences of message 181650.
This function moves the textbox but has no effect on its size.
Non-Rotated Boxes
Looking at the XYWH measurements palette of QuarkXPress and InDesign, the effect of this function is to set the value of X equal to nFixedUnits and leave the 3 other values unchanged.
Rotated Boxes
Textbox resizing functions only work on textboxes whose angle is a multiple of 90 degrees (0°, 90°, 180°, or 270°).
When using this function with QuarkXPress, you should not use this function on a rotated box. Instead you should rotate the text inside a non-rotated box, as explained in the gridtemplate construction guidelines.
When using this function with InDesign, it is the visual position of the box that is moved and therefore the changes to the values of XYWH will differ depending on the rotation of the box, ensuring that the visual result of this function is always the same.
