Abstract

A graphics display device is provided with a graphical input device which cooperates with means for addressing the display device's bit map memory (58) so that a viewport (56) into the bit map memory (58) can be panned in conjunction with a cursor (70) controlled by the input device. In particular, if the input device is operated for moving the cursor within the viewport (56) displayed on a cathode-ray-­ tube screen until the edge of the viewport (56) is encoun­ tered, the addressing of the bit map memory (58) is changed whereby the whole viewport appears to be moved by the cursor (70). Thus, if a transition is made in cursor movement from a location "inside" the viewport (56) to a location "outside" the viewport, the viewport is redefined such that the cursor (70) falls just within the viewport, as long as the dimensions of the virtual screen in the bit map memory are not exceeded.
