Inventions On Selecting Gui Elements, Umakant Mishra Dec 2005

Inventions On Selecting Gui Elements, Umakant Mishra

Umakant Mishra

Selecting an object or element is a fundamental operation in any graphic user interface. It is necessary to select an object before doing any operation (such as, dragging, copying, opening, deleting etc.) on that object. The GUI may provide features to select any single object or even multiple objects. The feature of selecting multiple objects can provides tremendous power to the GUI as the user can do complex operations on multiple objects in one go. However, the process of selection is not as simple as it appears to the user of a GUI. The internal logic of a selection mechanism …
