What is Drag-and-Drop?

Drag-and-Drop is one of the many user interface techniques designed to move objects on the computer. The "tow" action includes maintaining the main mouse button-in the default setting on the left-and then showed the mouse towards the target. On the other hand, "Drop" involves release of the main mouse button through the target target. This technique allows multiple applications in the use of the computer, including relocation and file arrangement. Some programs use the Drag-and-Drop method to simplify some commands such as data input.

The technique replicates the natural human movement for moving objects. By handling the mouse pointer as "hand" users can catch, move and lay different virtual objects down. This intuitive design is an industrial standard among operating systems, usually helps to allow the computer to be used for average people. Several e -mail clients, for example, allow you to drag the attachments of files and drag into an outgoing message. It saves the user time and efforts usually of the threatAzeno to find and connect a file via a separate dialog box. Drag-and-Drop technique is also used for various games, office programs and other software in which virtual objects are shifting. With the development of Hypertext Markup Language version 5 (HTML5), websites can include Drag-and-Drop features in code, allowing a more user-friendly interface.

Many touch screen devices use the method as the basis for their user interface techniques. Rather than clicking the screen several times for devices by devices, users can easily keep your fingers on the screen and "drag" towards the desired goal. "Drop" stops movement. Due to the small screen sizes on pocket devices, it may be necessary to perform a drag-and-droped several times before the desired result. This allows faster use of the device and also reduces wear to imagesheep.

However, there are certain limitations of the Drag-and-Drop method. During the procedure, the original and target targets must be opened. Although it is often a negligible problem, it is still possible for the target to be under the original layer placement, so the desired new location is inaccessible. The Drag-and-Drop is a remedy for this problem; The goal must be simply dragged and falling into the screen area from the original file location. There are other problems when designers change the convention, as in the case of computer trackpads; Instead of the buttons, users often click the pad before using Drag-and-Drop.
