What is a Text Box in a Computer?
A text box (or textbox) is a user interface element that (typically) looks like a rectangle and lets you write text to be used by an application or form when it has keyboard focus.
As fields, text boxes tend to be labelled with a label to its left or above them. In some cases, the field is not necessary if its function can be determined by convention.
Types of Text Boxes
- Combo box: a text box that displays a list of valid choices under it.
- Search box: a text box made for searching. It often shows last terms searched under it.
- Numeric entry with spin buttons: a text box that only allows numbers to be entered. It has an up arrow and down arrow button on its right to increment and decrement the value.
- Address box: a text box found in the address bar of an application that shows the address of the current location.
- Omnibox: the box found in modern web browsers that perform the functions of a search box and an address box simultaneously.
Tricks
In some cases, pressing the Enter key while a text box has keyboard focus performs a default action like submitting a form.
