    --see readme file for contact information
    This XControl provides a function generator wrapped up in an XControl that outputs an analogue waveform
    data type. Supports sine, square, ramp, saw tooth, parabolic, cubic, quartic and arbitrary functions with adjustable amplitudes, offsets, and number of periods with no further coding. User interface provides a graph that updates in response to user changes to the controls.
    XControl will adjust layout as it is resized, and provides properties to set the visibility of the axes scales, y=0 marker and a current index position marker.



  2. Vector Waveform XControl

    License: BSD
    Compatible LabVIEW Versions: >= 2018
    Compatible OS Versions: ALL.
    This package uses two instances of my Waveform XControl to make a vector waveform - i.e. magnitude and direction or x and y co-ordinates. The resultant vector waveform is plotted on the third tab of the Xcontrol. The XControl can be switched between polar or cartesian co-ordinate modes and it is possible to vary both co-ordinates together or repeating one for every point on the other - thus allowing 2D scans to be built up. The waveform is represented as a complex number where the real co-ordinate corresponds to the X axis and the imaginary to the y. I use this in my own code to allow users to control both a vector magnet and to setup a laser scanning system.
    Release Notes:
    This Package depends on these other packages:
    lavag_lib_user_interface_xcontrole_waveform_xcontrol >=
    oglib_array >= 3.0.0

    --see readme file for contact information
    This tool allows XControl to (seemingly) natural inherit properties from their daughters.
    Version 1.1 includes better documentation (F1), and is better structured and more fail save.This program will allow the generation of Inheritance for XControls.
    It offers the option to generate new XControls fit for this tool.
    The programs are called via Tools->XControlInheritance
    The programs are located under \LavaCR\XcontrolInheritance
    Installation via .OGP with OpenG Commander (http://commander.openg.com) or VI Package Manager (http://www.vipm.com/vipm).
    Or manual by placing the zip contents folder into %labview%\Project\LAVA\XControlInheritance
    Start up from 'tools->LAVA->XControlInheritance' and pres F1 for detailed instructions
    Good luck,
    The code uses the following OpenG libraries:
    Downloadable with VIPM (www.jkisoft.com/vipm)
    Change Log:
    1.1.1: Better structured, more internal control, better documentation
    1.0.8: Update after CR feedback
    1.0.7: Initial LavaCR release of the code.



  5. Boolean XControl

    Boolean XControl version 2.2

    This code was downloaded from:
    Direct OGP download
    This XControl has a configurable apperance, functioning as a boolean it can show a custom picture with a custom (formatted) text.
    On initial drop of the XControl it will show a browse window to load a picture (png, jpeg or bmp) as view of the boolean.
    After that the GUI configuration of the XControl is shown where the position of string an picture can be set amongst other things.
    The XControl has 3 possible boolean behaviours:
    -Switch when pressed
    The boolean value will change as soon as the mouse is down on the XControl
    -Switch when release
    The boolean value will change as soon as the mouse goes up on the XControl, the button will react on the mouse-down
    -Switch until released
    The boolean value will be changed when the mouse goes down and reverts as the mouse goes up
    The button itself can be a Modern, Classic, System or System Decoration style.
    Version 2.2.0 introduces nudging of the button, when the button is clicked the button (optionally) moves 1 pixel down,
    For the developer it has the following advantages:
    -Have a configurable boolean button with customizable interface and behaviour, all of the items can be controlled via VI-server
    Unzip to a custom location.
    Explore the possibilites with the included Demo.vi which is linked to the XControl in XControl\BooleanXControl_LCR.xctl
    To reuse this XControl in mulitple projects install the OGP file with VIPM (http://www.jkisoft.com/vipm), after installation it will be located in:
    You have to manually add it to your palette, since LabVIEW won't index XControls.
    To hide the use of the XControl to developers you should lock the facade vi (Abilities\BX.Facade__LCR.vi) so the 'Show diagram' options isn't shown.
    The zip includes a CreateIconVI.vi which will convert any given picture (preferably a 32x32 png) into a VI constant with the icon of the VI the same as the picture. This can be usefull to include some constant pictures inside code that is controlling the XControl
    Known issues:
    Do not apply multiple properties in one property node, this is a bug in LabVIEW 8.0/8.2
    See this LAVA discussion: http://forums.lavag....trol-t8869.html

    It will truncate a path to fit inside a (multiline) string.
    Besides basic funtionality it has the following properties:

    Truncated string (Read only property that will return the truncated string) Button Visible (Read/Write, this property will show/hide the browse button) Browse properties (Read/Write, this property will set/get the browse options) Multi-Line (Read/Write, this property will set/get the multiline option of the truncated path) Methods: Truncate Path (this method uses the VIs to truncate a path to a string) Truncate Multiline Path (this method uses the VIs to truncate a path to a multiline string) For the developer it has the following advantages:
    Set the browse options with a dialog similar to the native browse options dialog Browse for a path Show/Hide browse button Control the multiline-ness of the control Known issues: No drag and drop Bounds of indicator/control include (invisible) browse button Version history

    An XControl with enhanced features for the multi-column. To access X-Control features select More… from the shortcut menu.

    Automatic Ordering -. The Rows are ordered by a selected column in either ascending or descending mode (alphabetically). Columns can be selected by clicking on the column header with the hand tool. The sorted row is displayed in bold font with a \/ or /\ marker at the end of the name. Value Filtering – Rows can be hidden by applying value filters. The value filters will apply upper and lower limits (alphabetical) for columns. Alternate Line Colouring – Gives the Multi-Column Listbox a professional look by applying an alternating background and text row colour. Dependencies:
    Labview 8.5.x or higher
    Open G Array Library: oglib_array
    Change Log:
    1.2.0: Fixed edit cell behaviour. Improved ability to convet older versions.

  8. Multistate Boolean LED Indicator

    Multistate Boolean LED Indicator V1.0.0

    --see readme file for contact information
    I have had many people ask for an LED type indicator for their project. During development, I often get asked to have this Boolean (ie 2 state) indicator display one of (more than 2) colours.
    Whilst that in itself is not difficult, more often than not I am then asked to make the Boolean LED flash as well to highlight certain states.
    For example a single LED will often need to indicate the following states:
    OFF (green, red or grey)
    ON (Green, red or grey)
    Flashing (green, red, any other colour)
    I have had so much demand for this functionality, that I decided to develop this XControl and share it with the LabVIEW Community.
    Many thanks must go to Aristos Queue and his inspiring "Scrolling LED XControl" example.
    This XControl is a typical Boolean LED indicator that can also be configured to flash between two user defined colours. The flashing interval can also be modified.
    When not flashing, the XControl behaves as a normal Boolean LED.
    This XControl is an indicator only is is not intended to be used as a control.
    There are no OpenG dependencies for this XCtonrol
    Known Issues:
    If you save this code for version 8.0/8.2, you may encounter issues trying to assign multiple properties in one property node.
    This is a bug in LabVIEW 8.0/8.2

  9. simple gauge LabVIEW XControl

    GISXControl Technology Preview Version 0.0.1
    Copyright © 2009, Technogerma Systems France S.A.R.L.
    All rights reserved.
    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
    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.
    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.
    If you have questions or if you want to give some feedback you can send mail to gisxcontrol@technogerma.fr or post directly on GISXControl LAVA support forum thread.
