HSC style question:

A page setup screen for a graphics application is required to gather the following

information:

• The size of the left, right, top and bottom margins.

• Page orientation – either landscape or portrait.

• The printer to which the document will be sent.

• The final printed size of the graphic.

(a) Design a user interface for this page setup screen.

(b) Explain how the software could ensure that the data entered is appropriate.

Suggested Solutions

(a)

(b) The paper size can be determined directly from the printer driver. If the user

enters margin or graphic sizes that will not fit then these values are automatically

adjusted to fit the page size. The value just entered is retained wherever possible

and the other values are altered and reflected within the preview frame. Inputs

such as negative numbers or alphabetic characters simply cannot be entered.

These techniques mean that it should never be necessary to generate error

messages.
