Building the Front Panel

The front panel is the user interface of the VI. You build the front panel with controls and indicators, which are the interactive input and output terminals of the VI, respectively. Controls are knobs, push buttons, dials, and other input devices. Indicators are graphs, LEDs, and other displays. Controls simulate instrument input devices and supply data to the block diagram of the VI. Indicators simulate instrument output devices and display data the block diagram acquires or generates.

Each control or indicator has a shortcut menu you can use to change various attributes or select different menu items.

When you place a control or indicator on the front panel, a corresponding terminal appears on the block diagram.

Refer to the LabVIEW Custom Controls, Indicators, and Type Definitions Application Note for more information about creating and using custom controls, indicators, and type definitions.
