A method of controlling the display of a multiple-column document comprises displaying the columns in a viewport; receiving user input defining downwards scrolling for the document; determining the lowest numbered column that does not have its lowest point displayed in the viewport; and scrolling only this column, whilst all other columns remain stationary. The scrollbar may be sized to reflect the total height of the multiple columns in the document. When receiving input defining upwards scrolling for the document, the highest numbered column that doesnt have its highest point displayed is determined, and only this column is scrolled. User inputs defining downward scrolling when all columns have their lowest point displayed result in the entire document scrolling upwards; user inputs defining upwards scrolling for the document when all columns have their highest point displayed result in the entire document scrolling downwards. The invention is intended to make multiple-column documents more easily readable, by avoiding the need to scroll to the top of the page to begin reading the next column upon finishing reading a first column. |
