----------------------------------------
Description:
----------------------------------------
This project is a technology preview of a simple gauge LabVIEW XControl limited in features and visual aspect.
The XControl is based on a C wrapper on our Graphical Instruments Solution (GIS).
GIS is a set of instruments currently in development (Buttons, LEDs, Gauges, Knobs, Sliders, LCDs, Switches, Tanks, Thermometers, ...) with the following main features:
- C++ library based on Qt framework
- Multiplatform (Mac, Linux, Windows)
- Skin system based on SVG and XML to customize the appearance of each instrument
- Property system to customize the behaviour of each instrument
- Double license: Open source and commercial
---------------------------------------
Aim:
----------------------------------------
The purpose of this technology preview is to see if such a library of XControls could be usefull and to get feedbacks from LabVIEW users community.
---------------------------------------
Usage:
----------------------------------------
Windows
1. Copy mingwm10.dll, QtCore4.dll, QtGui4.dll and QtSvg4.dll into your LabVIEW installation directory (e.g. C:\Program Files\National Instruments\LabVIEW 8.6)
2. Open the project
3. Run the demo.vi
Linux and Mac
Not yet available. If you are interested in a Linux or Mac version please contact us.
---------------------------------------
Known issues:
----------------------------------------
- Performance issue when the value change rate is too fast. This will introduce a desynchronization between the current value and the displayed value.
This is due to the XControl architecture that stacks data changed events. See http://forums.lavag.org/XControl-DataChanged-events-stacking-t13459.html for more details.

Description:
Implements a blinking LED with adjustable blinking interval.
The value of this XControl is the blinking interval in milliseconds.
Minimal value allowed is 100ms. This XControl acts as an indicator only.
Inspired by Aristos Queue's "Scrolling LED XControl" example. Many thanks for that!
Dependancies:
None
Change Log:
1.0.0: Initial release.

Description:
This VI computes the Leventshein distance between two strings.
It is based on the pseudocode found in Wikipedia online:
http://en.wikipedia....shtein_distance
"The Levenshtein distance between two strings is given by the minimum number of
operations needed to transform one string into the other, where an operation is an
insertion, deletion, or substitution of a single character."
It functions by creating a step matrix which is N+1 x M+1, where N and M are the
lengths of the two strings to be compared, and filling in each cell of this matrix
indicating how many steps (insertions, deletions, character substitutions) are required.
The total number of steps to convert one string into the other is given by the last cell
in the matrix.
Change Log:
1.0.0: Initial release of the code.

Description:
This tool allows user to apply new icon templates to LabVIEW classes. New template is applied to each item inside the class. User can define which parts of the template is transparent so that the template can be overlaid on top of the existing icons.
