The QuarkXPress measurements editors are edit controls that have been modified to mimic the behaviour of the measurements editors in QuarkXPress. Namely :
•You can type in calculations using the 4 operators + -/* (addition, subtraction, division and multiplication), as shown below. This is particularly useful if you need to calculate the leading to use between a series of lines, or the step and repeat size to use.
•Each editor is setup to display a specific type of units (millimeters, inches, points or percent), but you can combine elements using various units, as shown below.
•You can type either a period or comma as decimal separator, and Q++ will convert it automatically to the proper separator as used by Windows on your workstation.
•Any value that you type without units will be treated as if it was specified using the default units of the current editor (this parallels the QuarkXPress behaviour).
The expressions you enter into these edit controls are evaluated whenever the focus switches to another control, or if you press the Enter key while the control has the focus.
