Use this tag for programming scenarios related to controls (interactive elements of the user interface).
A control is an interface element that a computer user interacts with.
Common controls include:
Window A rectangle that represents a "window" into a document, form, or design area.
Text box A box in which to enter text or numbers.
Button An equivalent to a push-button as found on mechanical or electronic instruments.
Hyperlink Text with some kind of indicator (usually underlining and/or color) that indicates that clicking it will take one to another screen or page.
Drop-down list A list of items from which to select. The list normally only displays items when a special button or indicator is clicked.
List box A GUI widget that allows the user to select one or more items from a list contained within a static, multiple line text box.
Combo box A combination of a drop-down list or list box and a single-line textbox, allowing the user to either type a value directly into the control or choose from the list of existing options.
Check box A box which indicates an "on" or "off" state via a check mark ☑ or a cross ☒. Sometimes can appear in an intermediate state (shaded or with a dash) to indicate mixed status of multiple objects.
Radio button A button, similar to a check-box, except that only one item in a group can be selected. Its name comes from the mechanical push-button group on a car radio receiver. Selecting a new item from the group's buttons also deselects the previously selected button.
Cycle button A button that cycles its content through two or more values, thus enabling selection of one from a group of items.
Datagrid A spreadsheet-like grid that allows numbers or text to be entered in rows and columns.
Slider A bar that allows users to make adjustments to a value or process throughout a range of allowed values.
