• Fire graphic cursor move event programmatically

  Is it possible to programmatically trigger the move bar graph event?  Assign a value to the Index of the cursor or the property node Cursor Position does not seem to do.

  Create a user and set up the case of the event which handles the cursor movement to handle that event as well. Then fire this event when the data updated?

• the exact position of the mouse click xy graph while he plotted graph with mouse events

  Hello

  IAM using Graph xy for multi locations

  IAM traced graphic with mouse movement and events using the example attached (draw the graph with mouse events)

  but in sub vi Values.vi scale there are two constants 66 and 30 when I change my plot (I also change the scales), then the mouse position and chart position (cursor) value are not well aligned, but when I change the constants mentioned above I get the alignment perfect between the cursor and the last point in the path.

  as I went to another parcel (with scalability again) the same alignment problem resurfaced.

  I need to replace these two constants with something dynamic

  Please help

  solution to my problem is

• No PropertyChanged event when its plot is changed due to a stretch in NearestPoint SnapMode fire on XYCursor

  I have a graph of waveform with two parcels and a cursor with = NearestPoint SnapMode.

  When you remove the plot that the cursor is currently pointing, I want to associate the slider with another plot.

  For this love, I subscribed to the the cursor PropertyChanged event. When the plot of the cursor change, I expect to be drawn from this event. In the handler, I agree with the Disposed of the new plot event. In the Manager has, I point the cursor to another plot.

  The problem with this approach is that the PropertyChanged event is not raised when the cursor is moved from one parcel to another plot.

  Although there are several ways to work around this problem, this behavior is unexpected. I expect a PropertyChanged to be triggered whenever the plot of the cursor property changes.

  Reproduced with version 2010 SP1 (9.1.0.204)

  Seems that they have made some changes in 2013 MS, see 384987. Thank you for the study.

  I'll look into it when you upgrade.

• What is different between the event create and save

  I do not understand the position of the event details, create and save, I want to know the behine the theory of functions. Can anyone give some information?  Thank you!

  You can set the part listening to an event in the register for events.
  -Create and destroy functions are necessary for user events.
  -If you always talk registration of events front, yes you can do it dynamically register events and you must create and destroy the user event: https://zone.ni.com/reference/en-XX/help/371361K-01/lvhowto/dynamic_register_event/
  -If you can post vi/extract it might explain a little better what you're asking.

• How do I know what cursor is moved in a XY Chart with several cursors existing.

  
  

  The XY-graph has a cursor-exit event., this event will return an index which the cursor has been moved.

  Good luck

• How to create the 2d cursor?

  How can I create slider 2d, something like the square with the point of the mouse controlled inside in the upper left corner in the photo, so I don't need to use 2 separate cursors for x and y?

  

  Altenbach says:

  Create a style point (not lines) cursor and cursor movement events for x and y.

  Here's what I had in mind (LV 8.0). Modify if needed.

  

• Programmatically trigger cursor output?

  Hello

  I use the framework of the actor to develop a large application in LabVIEW. I have the sliders on a graph that trigger data be filled by actors using a structure of the event and a cursor output event. The data are also met (initialized) when the program starts.

  I currently do this initialization using a structure below and a change event of value on the "Init": Boolean

  

  also described here:

  http://forums.NI.com/T5/LabVIEW-idea-exchange/add-first-run-event-on-event-structure/IDC-p/1044975#M...

  The problem with the help of the 'init' Boolean is that I duplicate the same code in two events: "init": value change and "graph": output cursor events (the event two do exactly the same thing).  Does anyone know how slick combine these the Init event with cursor output event so that the cursor output event fires start? That way I wouldn't have to duplicate my code in two places...

  I've searched and have not found exactly what I needed, sorry if this has been covered somewhere in the forum.

  Taking place your common code? In case the Structure? Could register just for two events:

  

  Or to register for the event separately to send it to the nested actor:

  

• Active cursor (property node). You will need to obtain a number of active cursor.

  Hello world

  I have searched for this answer for a while and found no one. So, let me describe my problem:

  I have a XY Chart with 10 sliders on a FP. On the comic, there is an event-driven state machine.

  I want to use a node of ActCrsr materials for a number of active when cursor occurse event (event of slider type for example). Unfortunately, LabVIEW gives me only 2 numbers of cursor and I don't see any logic behind it!

  Why do I need? Imagine, when you take a cursor, the graph to which he belongs to type of assets (the line is thick and the name appears and so on). My program visualizes graphic adjustments of pulses.

  

  Thank you very much in advance!

• LabVIEW event to re-establish control not recognize.

  I am having trouble with an app I'm trying. I am trying to create a UI that updates some indicators and sends an analog output. I use a state machine in queue and cannot understand why the control is not to release day.

  Is anyone able to take a look?

  Downloaded an image, can download the .vi if necessary.

  -Ian

  The problem is that you have the data sent in the queue on the valve Position value change event.  This is a Boolean value, you have on your front.  And since it is an indicator, you can never actually have a value change event unless you do it programmatically.

  I think you want that your value change event must be associated with the control of the 'value of valve Position".

  Two other comments.

  One, you must connect your queue reference in any event.  If you have not, it will be a strange situation program who will be met, especially when you add to your program that will result in data in this thread that leaves the structure of the event to be bland and set its default value.

  Two, even though I know you have some reasons for hiding and showing controls, have controls appear and disappear as it seems not be a very friendly user interface, whereas it is difficult to say how to make appear whenever you want.

• drag cursor problem

  Hi all

  I have some problems playing with movement of the sliders.

  In my application, I have a chart with 2 sliders. There is 1 primary cursor (black color) that can be moved can on the chart. And another (in green) cannot go to the left of the black.

  On 'Move cursor' (green) event, whenever the value of the cursor X is less black, I do value let slip false. But it's not working.

  Could you pls look at my Vi and suggest me a solution.

  Thank you

  Ritesh

  Sorry, of course you should get the x directly from the terminal event. No need to ungroup.

  

• Cursor LockTimeoutException

  I have a database that I deal with as a queue. Multiple threads question this 'tail' by opening cursors and pulling the first record which has not already been claimed by another thread. Multiple threads of the writer to add to the queue (indexed by sequence).
  
  After a few minutes or a few hours, I will get a LockTimeoutException in a thread of reader that is caused by a transaction of writer thread.
  
  My logs indicates that the activity is:
  
  Player:
  TransactionConfig conf = new TransactionConfig();
  conf.setReadCommitted (true);
  TXN = env.beginTransaction (null, conf);
  database.openCursor (txn, CursorConfig.READ_COMMITTED);
  loop: cursor.getNext (keyEntry, valueEntry, null);
  
  While the drive is a loop in getNext...
  
  Writer:
  TransactionConfig conf = new TransactionConfig();
  conf.setReadCommitted (true);
  TXN = env.beginTransaction (null, conf);
  ...
  Sequence.get (null, 1);
  Database.put (txn, keyEntry, valueEntry);
  TXN.Commit ();
  
  It seems that at the time wherever the author tries to validate that everything grinds a setback to 500ms lock wait time. The reader thread then up the LockTimeoutException, then the writer finishes it is the validation operation and continues.
  
  The exception looks like this:
  com.sleepycat.je.LockTimeoutException: (I 5.0.58) lock has expired. Locker 844587133 - 1_http_ReadCommittedLocker: waited for lock on the database = http LockAddr:109037661 LSN = 0 x 1/0x1d098d type = grant READ = WAIT_NEW timeoutMillis = 500 startTime = endTime 1349247160593 = 1349247161095

  Son of reader is recommended to use of Serializable Isolation at the opening of the transaction for the reading of the cursor?
  
  My assumption since I read only validated data that the new record added by the author will not be seen by my reader thread and readers wouldn't hurt so not with the writers. Where I'm going wrong?
  

• Simultaneous animations on the same event Enter_frame

  I created a class that extends a line on Enter_Frame event. I want to display on the stage, but I want to animate its position using Enter_Frame event.

  How to do the two animations at the same time?

  I have added this script to the timeline:

  gLine.addEventListener (Event.ENTER_FRAME, movegLine);

  function movegLine(E:Event):void {}

  If (gLine.x < = 800) {}

  gLine.x += 1;

  }

  }

  where gLine is the instance of the class lively.

  The result is that, AS anime position, then animates the extension of the line. But I want the two actions take place at the same time - something like the rotation of the wheels of a car at the same time, moving to the position of the car. Any suggestions?

  I think I have discovered my error. The scene must add the listener of events such as opposted to the line

• Duration of formatted by adding to the current position

  Hello

  I want to have an external button that will insert a SpanElement formatted at the current position.

  How can I insert my own items in the required position (cursor)?

  Element might look like:

  var span:SpanElement = new SpanElement();
  span.text = text;
  span.setStyle('custom',true);
  span.color = '0xFF0000';
  

  Thank you

  Find the item of the sheet using texFlow.findLeaf.  If the position to insert is in the middle of a splitAtPosition to use span to split in two.

  Calculate the index that you want to add the new span using parent.getChildIndex and now the API replaceChildren to can insert your new span.

  Hope that helps,

  Richard
