void = SetBoxWidth(nFixedUnits)
the XYWH measurements palettes of QuarkXPress and InDesign
This macro function is used to specify the width of the textbox that contains the macro token as nFixedUnits.
nPos = SizeMm(100000) // 100 mm or about 2.5 inches
SetBoxWidth(nPos)
This function will affect the width of the textbox, keeping the left position unchanged.
Non-Rotated Boxes
Looking at the XYWH measurements palette of QuarkXPress and InDesign, as shown in the image on the right, the effect of this function is to set the value of W 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 width 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.
