• How to add collapse and expand the listener of events on a treeview

  Hi all:

  I want to do something when the item reduced treeitem or developed, but both clicking on the icon of the element tree and double clicked on tree can reduced or developed tree item.so how to listen to collapse and expand your event?

  Thank you very much.

  TreeItem has an extended property, add a listener to it.

  item.expandedProperty () .addListener ((observable, wasExpanded, isExpanded)->)

  do something based on the change of ownership of expansion

• Listen to the event within the custom class

  I created a custom class that publishes on a webpage to authorize a user. How can I listen to an event within the custom class?

  It is my code in my main class.

  var customClass:CustomClass = new CustomClass();

  var testingString = customClass.authorize ("[email protected]", "password");

  the fuction "authorizes" within the customClass looks like this:

  public void authorize(user:String,_password:String):void

  {

  jSession = new URLVariables();

  j_Loader = new URLLoader();

  jSession.j_username = user;

  jSession.j_password = password;

  jSend.method = URLRequestMethod.POST;

  jSend.data = jSession

  j_Loader.load (jSend)

  }

  How can I trigger an event in my main class once the j_Loader triggers Event.COMPLETE?

  You can raise an event using the dispatchEvent() function.

  In your main class, you assign a listener to the event the CustomClass distributes when there are.

• A structure of the event within a certain time out loop.

  I'm relatively new to LabView and in particular the structure of the event. I was looking at the previous posts regarding the structure of the event and the difficulty to stop people. In my VI, I have two cases of event besides the time-out. I use this VI for control of stepper motor. I have 2 buttons (for each case), a movement to the left, the other to the right. It works as it is supposed to, but when I try to turn it off I have to press the two buttons before it stops. As if the loop should run everything inside before stopping.

  In my VI, how can I do the execution stops when I press the stop button? I tried many configurations of the stop button and boolean logic (which I believe was correct), but I am now stuck.

  Thank you very much

• Add the occurrence to a structure of the event by using scripts

  Hello

  IAM trying to (using scripts) updating a structure of the event (the case of the event add) on a vi is not on memory.

  I get error 1054 the specified object was not found.

  Here's a picture of him.

  any help in this will greatly be apreaciated.

  The error comes from the open air, because looking for structure in the wrong place. While it is perfectly logical that the owner would be the loop in practice yet script is not that friendly - you need to get the reference of the schema of the loop and use it as an owner.

• Add the event handler as the Internet or through prototype?

  I would try to increase my knowledge of javascript here.

  So, here's what I got so far, and I would like to do better. I have seen that if you click on 1 pixel at the border of a drop-down list in CC ScriptUI, it will have the adverse effect of the selection "null", which has overwritten some of my scripts. This is why I made this 'prototype' which selects the first element, someone should trigger a null inadvertently selection effect by clicking on the border of the dropdownlist control.

  DropDownList.prototype.selectWell = function() {}

  CC will allow you to select the null value

  this.addEventListener ('change', function() {}

  If (this.) Selection == null) {}

  This.items = This.Selection [0];

  }

  });

  }

  The way it works is like this:

  var d = window.add ("dropdownlist', undefined, ["Item 1","2"]");

  d.selectWell ();

  OK, it works, but then you I write "() d.selectWell;' after each dropdown. "

  Each new instance of a DropDownList already it would be possible to write a code that comes with this event listener is added?

  In javascript of the browser, they have querySelector (element) to add a listener for each element of the desired type. I don't know it is also available in ScriptUI.

  I suppose it would be possible to mass of the port of listening via the recursive function assignments, but should be repeated in the windows where the new drop-down menus are added dynamically.
  Also, I could make my own constructor, call SuperDropDownList and in this constructor adds all the necessary headphones and use it to add a menu drop-down that I want to have custom features.

  However, if it could be done with a simple ""DropDownList.prototype ", I would like to know how to do! "

  where is this 1px? I couldn't click on it...

  Here's a way to do

  DropDownList.prototype.onChange = function() {
      //CC will let you select null
  
      alert('on change ' + this.properties.name);
      if (this.selection == null) {
          this.selection = this.items[0];
      }
  
  }
  
  var w = new Window('dialog', '');
  var d = w.add("dropdownlist", undefined, ["Item 1", "Item 2"], {name: 'one'});
  var d2 = w.add("dropdownlist", undefined, ["Item 1", "Item 2"], {name: 'two'});
  //d.selectWell();
  
  w.show();
  

• How to manage the structure of the event with two loops

  I have a question about the structure of the user event with 2 buttons?

  key 1: START LOGGING DATA

  key 2: STOP LOGGING DATA

  How do I control my

  structure of the event so that it will work? because now that the loop is save data... I can't stop the loop, when I clicked on buttons.

  the problem with moving it is that I don't have control of the DATA RECORD STARTING?

  Of course, you do.  When you get your press conference button, you say your state machine to move to the State of logging.  You must also make sure that you return to visit the State to wait for the event to check out the events of the stop button.

• Control does not after the exit of the loop of event handler

  My application brings together several controls user input.  When the user presses the OK button, it exits the event handler and the treatment.  During the treatment, it is not able to read the new values of the controls.  And in fact is no longer meets the stop button.

  When executing the attached VI, you will find that you can press the button of the switch and the LED indicates the status of the switch (this is my input from the user).  Now, press the OK button.  If you press the switch button, you will see that it works only once.  In addition, the stop button unresponsive to user input.  If you do not press the button, the stop button will cause the 2nd loop exit.

  Why the 2nd loop is unresponsive to the switch?

  It is a simplified version of my application in which two loops are separate from the States of my state machine.  There are several other States as well.

  The case of the event of the "change value" event has the property set to lock the Panel before the VI when the event is raised until the case of the event is over.

  Because the left while the loop is running not but the structuer event is always active FP everything is locked.

  Uncheck this option in the "edit event".

• conditional of the loop will not control read in a business event

  I made a simple conditional to the loop, with a timer and a generator of random numbers in the loop as a stop button attached to the conditional stop Terminal.  Everything works well and stop the loop when I click on the stop button. But I then wrap the conditional for the loop with a structure event and create an event to run the conditional for the loop.

  To my surprise, when I run this updated VI I can never get the loop to stop via the wired button until the conditional terminal stop.  How is what happens? And how to do this?

  change the case of the event > UNCHECK block façade up to the case of finishes (or whatever this text indicates actually in the lower left corner of the pop - up of the event edit)

• structure of the event within the structure of the case? error or limitation of LabVIEW?

  Hello

  I am trying to reach a structure of the event within a box structure. The event is triggered by a mouse event (mouse down, move to the top).

  This vi tries to simulate behaviour of the device with a sensor, so the mouse triggered the structure of the event, won't be there in real working environment, so I can't remove the structure of the case.

  But as I noticed that if I try to click on the drawing (that my mouse events are triggered with) before activating the Boolean condition of 2D, I can access is no longer the component front (button, leads, etc.).

  They seems to be frozen. But if the case is true before you try click on the 2D drawing area, everything seems to work well.

  Is - this protected by a kind of LabVIEW bug or there is a limitation?

  These are my screws.

  Thank you

• Activation of the loops through the events

  Hey guys.

  Let me start of by saying that I am self taught in LabVIEW and just started. The problems I encounter are so simple.

  Let me describe what I do, and then the problem that I need help. I am trying to automate a research facility that uses a series of valves, a massspectrometer and a potentiostat. I want a VI where I can press a button that causes the valves to open and close, in a given order, after which the massspec should make an experience, the experience, the valves must open closes in a certain order and return to an "inactive" State In fact I want several of these buttons for a different experience.

  Now to my problem: I did a VI that does something in the sense of what I wanted using events and while loops. See attachment for a simplified version. It uses a structure of the event with two buttons which activate their own business structure. However, if I place the eventstructure outside the while loop, the event is still running. If I place the event indoors (as in the example) the while loop I have to press one for each stage of the structure of the case. Note that "business" in the structure of the case are identical in the example, but they will not be in my final version of the program. Finally, the LEDS indicate whether the valve is open or closed. The LED matrix, y at - it instead a DAQ assistant.

  I hope that people can help me, please tell me if it needs to be clarified.

  It looks like you want a State in queue Machine or the Machine of State JKI.

• Producing a XY chart in a While loop that adds a new point XY to the curve from each while the loop iteration

  I would like to plot data by using the XY graph as a Visual display. I have a While loop that creates a new point X and Y during each iteration. I need the XY graph to be in the While loop, because once the order to stop has been pressed the sis loop finished and the final graph to be displayed. The problem is that after each iteration, the XY graph display clears and watch point, compared to add the new point to the previous by a line connecting the two points. It works perfectly if I move the XY graph out of the While loop, but it only shows the XY graph at the end of the While loop. I would like to visually see the XY graph updated during the execution of the While loop. Any help would be much appreciated.

  Thank you

  You can add a data both point to a chart to a chart, you must pass the entire data group.  I would use a couple of shift registers in your loop.

• Structure of the event inside while loop

  I'm still fairly new to Labview and this may seem a simple question.  I'm doing a Subvi to display, edit, and create configuration files.  I use a ListBox to list all sections of a config file and structure of the event to update the values in each section, when they are clicked.  The problem is that the structure of the event seems to be a break the while loop so that the buttons do not work until the event has executed.  What I would like is the while loop to run continuously and the event to run only when I click in the listbox control.  I hope this makes sense.  There is a peak in the diagram below. Thank you

  There are a number of issues with your code that could cause problems:

  1. You must use the FP. Open method to open the front panel of a VI and of the public Service. Close method to close. I don't remember exactly the problem, but starting with the 7 worm nor indicated that these methods were the preferred way to perform these tasks.
  2. Based on what seems to be the code, the event for the control of Presets of wood should be a change the value - not a mouse down event. After changing the type of event, use the event data NewVal to drive the indexer table index entry.
  3. The buttons Ok and cancel them should be handled in their own events to change the value. The value change event Cancel would exit the loop, while passing the output error (which indicates that cancel was pressed) and default values for the other 4 outputs. The change of the value Ok event would leave the loop by passing the values that the operator had concluded the 4 controls on the front panel.
  4. An event of timeout with a very short time (1 msec) would stop loop if an error has occurred, or the output of the gate AND is set to true.
  5. The wait function is not necessary, as is the case outside the loop structure.
