Numeric Controls and Indicators (PDA Module, Touch Panel Module)
PDA and Touch Panel VIs support the following functionality for numeric controls and indicators:
- Captions and labels.
- Floating-point, scientific, and engineering notations.
- Multiple needles on dials, meters, and gauges.
- Resizing and changing the color of the increment and decrement buttons.
- Text justification and underlining text.
PDA and Touch Panel VIs do not support the following functionality for numeric controls and indicators:
- Radix or unit labels.
- Significant digits.
- Options in the advanced editing mode of the Format and Precision page of the Numeric Properties dialog box.
- SI (System International) or relative time notations.
- Time and date formats. Use a time stamp control instead.
- Dials, meters, and slides do not support digital displays or ramps. You cannot invert the scales for dials, meters, or slides. Scales must be linear.
- Data ranges that are different than the display range.
- 64-bit signed or unsigned integers. If you use 64-bit signed or unsigned integers, LabVIEW generates 32-bit signed or unsigned integers when you build the VI into a PDA or Touch Panel application.
- Extended-precision, floating-point numerics. If you use extended-precision, floating-point numerics, LabVIEW generates double-precision, floating-point numerics.
- Two sliders on a slide control. If you use two sliders, an error occurs when you build the VI into an application, and the application contains only the first slider and its default value.
