What is the difference between an uneditable and an editable combo box? Which of these is a combo box by default?

Short Answer

Expert verified
Answer: The main difference between an uneditable and an editable combo box is the user's ability to modify the list of options. In an uneditable combo box, the user can only choose from the predefined list of options, whereas in an editable combo box, the user can add new items or modify existing ones. By default, a combo box is uneditable, meaning that it allows users to choose from a predefined list of options without modifying the list.

Step by step solution

01

Define uneditable combo box

An uneditable combo box is a user interface element commonly used in graphical applications. It allows users to select one item from a predefined list of options, but the user cannot type or modify the options in any way. This type of combo box is ideal for situations where the available options are fixed and the user should not be able to add or modify the options.
02

Define editable combo box

An editable combo box is a user interface element similar to an uneditable combo box, but in this case, users can type or modify the options, allowing them to add new items to the list or edit existing ones. This type of combo box is useful when the available options may change, or when the user should have the flexibility to create their own options.
03

Explain the difference

The main difference between an uneditable and an editable combo box lies in the user's ability to modify the list of options. In an uneditable combo box, the user can only choose from the predefined list of options, whereas in an editable combo box, the user can add new items to the list or modify existing ones.
04

State the default combo box type

By default, a combo box is uneditable. This means that when a combo box is created without specifying its type, it will automatically be an uneditable combo box. Users will only be able to choose from the predefined list of options and will not be able to modify the list.
