What is a dialog box?

The dialog box is a field, a window, or a message that appears on the computer monitor and tells something to the user. These boxes often appear as notifications or warning to the computer that are about to do something that can have negative consequences, such as closing the program without first imposing information. It may also seem that the dialog box can be aware of the computer users, that something has happened, which may not be aware of otherwise, and to ensure communication between computer software and user. The box usually appears as a separate window or pop -up window. The dialog box is part of the graphical user interface (GUI) of the computer system or operating system and allows you to communicate information to the user of the computer.

The type of information communicated via the dialog box and the type of field used often depends on the specific situation. Information generally communicated through such a box informs the computer user that a particular event has proven or thatHe will do soon. For example, if someone closes the program, but has not yet saved information in this program, the box seems to warn users that the information will be lost if they do not. The dialog box may also occur if the program suddenly terminates, often called dropping to realize that the user has ended and gives the user any information about errors.

There are two basic types of dialog windows: modal and modern. Either of them will usually require a type of input from the user before disappearing, for example, confirming the user's vision user or selecting one of several options. The modal dialog box stops a program that concerns a box that appears on the box from the procedure, and the user cannot interact with this program when the box is present. For example, if someone closes the program without saving, it seems that the modal field warns users of data loss, and this would prevent it from closing it until the user confirms the action using the field.

Modelless dialog box on the other hand does not change how the program starts, so the program can continue its operation. This could happen if the program performs a lengthy task, such as copying information or drawing a complex scene in the graphics program. Such unconditional fields can enable computer users to cancel or change the task, even if the presence of the box does not prevent this task.
