• problems with event handlers

  Hello world. I have a problem with the start of the event handlers in InDesign CS3. The example code I wrote the tutorial book, will not work. The message that I get when I open a new document is: "error string: the requested operation could not be performed because the object no longer exists." Here's the code I used:

  --------------------------------------

  main();
  main() {} function
  myEventListener var = app.addEventListener ("afterNew", myDisplayEventType, true);
  }

  function myDisplayEventType (myEvent) {}
  Alert ("this event is the" + myEvent.eventType + "event.");
  }

  ------------------------------------

  What's not here? Thanks in advance,

  mileking

  Hi mileking.

  Use the code example below:

  Code example
  #targetengine "session". main(); main() {} function myEventListener var = app.addEventListener ("afterNew", myDisplayEventType, false); } function myDisplayEventType (myEvent) {} Alert ("this event is the" + myEvent.eventType + "event."); }

  Kind regards

• Dynamics of code in loop problem with event handlers

  Hello
  
  What I'm trying to do, is to assign dynamically a deployment and behavior pleased each movieclip with a certain name on my stage. I'm a loop through and attach a function to the event of each movieclip. So far, it works. All the clips on roller and more doing something. However the problem I'm having is dynamically changing values in each function for each different movieclip in a loop. For example, I store the clip I'm targeting original X and Y coordinates in an array that I push in the value to each loop. I draw it to test and trace it correctly on each loop of each value of X and Y for this clip. The problem I have is I am tempted to call orgX and orgy to each loop and attach that to each function, but all the clips using the last value in the table. It is not dynamically attaching the new orgX and orgy to each individual event deployment clips. All deployment events and more are called for each clip, but when I try to put any dynamic code in the function he always uses only the last value. Even if I put a trace in the RollOver event and try to find the instance name of movieclip clips all the clips to trace the last name of the clip on working capital. My logic looks OK but it has to do with how flash events attached runtime? How can I solve this problem?

  These tables are not something and orgX and orgy change values with each iteration of the loop for. at the moment where you deploying your movieclip orgX and orgy will be the last value in the loop for.

• Management events JFXPanel drag a expensive impact on performance with event handlers

  We have a drag event handler, which is a bit expensive, takes something like 20 ms. However, the code must be run synchronously.

  Is no problem in a pure environment of JavaFX, less events drag are created when the CPU load is high.

  However, when they are incorporated in the Swing using JFXPanel, this adaptation doesn't kick in, many events drag is created and the application become slow.

  Is it possible to imitate what JavaFX in the JFXPanel scenario?

  The code below is a stand-alone example that shows what I'm describing.

  Some results I got:

  -eventHandlerSleep = 5 - noswing-128 events > drag

  -eventHandlerSleep = 30 - noswing - > 46 events drag

  -eventHandlerSleep = 5-> 136 events drag

  -eventHandlerSleep = 30-> 135 events drag

  Yes, it is a known problem or expected, even if I don't remember the JavaFX bugs filed on this issue. JFXPanel is known to have some different problems with the sending of the event, such as Swing and live JavaFX on two threads. Drag-and - drop are required to be synchronous, so we enter a nested event loop while sending events to the Swing DND to JavaFX. It is the source of performance issues that you observe.

• Problems with events in flex

  Hello. I'm a guy AS2 and Flash CS3. I started to learn AS3 and Flex 3 transfer. But I had a problem w / events in AS3. I add a component of the canvas to the scene. On this canvas, I added 3 different events: mouse down, mouse move, and mouse upwards. When the mouse move is triggered, it is impossible for me to get the mouse an event triggered, and vice versa, when the mouse upward is triggered, there is no way to get the mouse don't move event triggered. Is there someone to help this newbie with this problem? Any help will be much appreciated.

  Code:

  " < = xmlns:mx mx:Application ' http://www.Adobe.com/2006/MXML layout "="absolute">
  < mx:canvas id = "myCanvas" x = "50" y = "50" width = "500" height = "500" click = "event_1 (); "mouseMove ="event_2 (); "mouseUp ="event_3 (); ">
  < / mx:Canvas >

  {Alert.show ("Second event fired") ;}}
  public function event_3 (): void
  {(Alert.show ("troisième événement déclenché) ;}}
  < / mx:Script >
  < / mx:Application >

  The problem is that your event listeners are not properly configured.

  Your "p1" to listen for the 'mouseUp' event because he was managing the events at this time.

  This is your modified and test code, as long as the mouse is down on the canvas, she fares at the time where you 'mouseUp' stop drawing.

• How to reference clips video parent/child with event handlers?

  I wonder how to reference correctly clips video parent/child, creating event handlers?

  I have a button in a movie clip, which is located in a clip.

  That's what my manager looks like now:

  This. DropMenus.DMSeats.ButtonSeats.addEventListener ("click", SeatsOver);

  The button instance name is ButtonSeats

  It is, I get this:

  TypeError: Error #1009: cannot access a property or method of a null object reference.

  Any idea where I could go wrong?

  Also, if I were to move the listener to drain directly into the clip where the button, how could I make reference to the parent/parent timeline (the main timeline)? Am I right to understand that .This refers only to the current clip?

  Thank you!

  You can place your code in a function that is called when your objects exist.

• Problem with event listener

  Hello

  We have an event listener that does not seem to receive all events insertion of a table.

  Here is the SYS. Order ADD_LISTENER that we use:

  call the SYS. ADD_LISTENER ('tpch ', 'SQLFIRE', 'lineitem', 'demo.vmware.sqlfire.greenplum.MultiHubProxyDispatcher',' connectionurl = jdbc:sqlfire: | numproxies = 4 | sqlfire = username: password = sqlfire ", null);

  MultiHubProxyDispatcher() code distributes the rows inserted between the four tables proxy (proxy_0 through proxy_4). I have attached the MultiHubProxyDispatcher() code in this post.

  Thus, after 2400 lines are inserted in the lines of only about 125 lineitem table are spread to each of the tables four proxy.

  sqlf > select count (*) in the sqlfire.lineitem;
  1
  -----------
  2400

  1 selected line
  sqlf > select count (*) in the sqlfire.proxy_0;
  1
  -----------
  125

  1 selected line
  sqlf > select count (*) in the sqlfire.proxy_0;
  1
  -----------
  125

  1 selected line
  sqlf > select count (*) in the sqlfire.proxy_1;
  1
  -----------
  129

  1 selected line

  This same event receiver code worked with SQLFire v1.0, we have recently updated to v1.0.3.1 and that's when we started to see the problem. I don't see anything unusual in the newspapers. Is there something that has changed with the SYS. Order ADD_LISTENER are we missing?

  Thank you
  Sean

  Hi Sean,.

  I think you want to attach the code for demo.vmware.sqlfire.greenplum.MultiHubProxyDispatcher but I see only MicroBatchListener.

  Looks like you are using both the AsyncEventListener, but also the listener to table which could be added through the SYS. Procedure ADD_LISTENER.

  Can you please write how you use the combination.

  Please note async event listener cannot be added through sys.ad_listener.

  Thank you

• Problem with event CreateJS

  I am trying to add an event listener to one of my symbols in Flash. Here is the code:

  / * js

  This.Stop ();

  function handleMouseEvent (evt)

  {

  evt.target.gotoAndStop ("over");

  }

  this.addEventListener ('mouseover', handleMouseEvent);

  internship. Update();

  */

  The symbol has been created on the stage and when published by using the CreateJS extension, it errors every time in the browser to the line where I use the addEventListner method. The error is basically saying there is no method like the one defined. Now, in this video of Grant Skinner, it does basically the same thing but with an older version of the API CreateJS: lish-to-html5-using-the-adobe-flash-professional-toolkit-for-createjs/ http://tv.adobe.com/watch/getting-started-with-flash-professional-toolkit-for-createjs/pub

  Why it doesn't work in my example?

  The issue is that toolkitforcreatejs is using Easeljs version 0.5.0 new event model was introduced in version 0.6.0. Update of version 0.6, and it should work for you.

• [JS CS5] problem with memory leak possible with the dialog box in the event handler

  Hello

  I'm having a very difficult problem.

  I am attaching a script in a handler for a menu item, by using an installation script menu that I wrote based on one by Marc Autret. My version of the script menu installation attach a bunch of event handlers at the same time, to the actions of different menu.

  What is the event handler, with that I have a problem is to prompt the user for a URL and then applies the URL as a hyperlink to the text selection, with our house style for the way in which the URL should look like.

  The problem is the following:

  1. all other installed menu actions work very well, except for this one.

  2. the addition of URL script works fine, when you run it directly from the script menu.

  3. the combination of #1 and #2 (using the script to add URL by function as an event handler in the Edit menu) blocks to InDesign. But it is only after the addition of URL script has finished and done what it was supposed to do!

  4. when I comment on the section of the script URL adding user input, so that instead of saying

  userInput = myDisplayDialog();
  

  It is said

  userInput = "http://thisworks.com";   // userInput = myDisplayDialog();
  

  It works well as an event handler.

  So obviously a problem with the dialog box, but only when adding URL script is executed as an event handler. My first guess is that this is some kind of memory leak, but I think I am following the model of. destroy() the way I saw it elsewhere.

  Someone knows something like that before?

  I can provide all relevant if necessary scripts, but they are quite complicated. The most important of them is the input of the user function. Here it is:

  var myDisplayDialog = function( defaultText ) {
    
      var defaultText = defaultText || "";
      
      var myDialog = app.dialogs.add({
          name: "Type in a URL"
      });
      
      var myOuterColumns = [];
      var myInnerColumns = [];
      var myOuterRows = [];
      var myBorderPanels = [];
      var myTextEditboxes = [];
      var myInput;
      
      myOuterColumns[0] = myDialog.dialogColumns.add();
      myOuterRows[0] = myOuterColumns[0].dialogRows.add();
  
  
      myBorderPanels[0] = myOuterRows[0].borderPanels.add();
      myInnerColumns[0] = myBorderPanels[0].dialogColumns.add();
      myInnerColumns[0].staticTexts.add({
          staticLabel: "URL:"
      });
      
      myInnerColumns[1] = myBorderPanels[0].dialogColumns.add();
          
      myTextEditboxes[0] = myInnerColumns[1].textEditboxes.add({
           minWidth: 300,
           editContents: defaultText ? defaultText : "http://"
      });
      
      var myResult = myDialog.show();
      var myInput = myTextEditboxes[0].editContents;
      
      myDialog.destroy();
  
      if (myResult == false) {
            exit();
      }
      
      return myInput;
  
  }

• Problem with the change in value of listbox event

  Hello

  I have a problem with the help of Listbox value change event. The code that I have attached is a simplified version of the largest program, but the problem is the same. One of the loops of Nonna is responsible for handlig occurring events ant the other is responsible for the execution of the program. In the project of oryginal I use a listbox control to determine which plots graphic display of a waveform is visible (first position of the listbox-> only plot first visible etc.). In the attached vi, I just show the current value of the listbox control. The problem is the event runs only once and then the program crashes. I want to be able to change the value of the listbox work both at idle and in State of a program, but when I put the structure of the event in both States, he does not. I'd be very grateful if someone smarter than me could tell me where I made my mistake. I want my program to be able to manage the keys and listbox events in States (slow down and knit) program.

  You have two structures of event in two cases different from the structure of the case, and both are tuned to listbox events has changed. Because only once can be triggered at any time, the VI crashes (lock events the front panel (default) until the event can complement).

  You must use a unique event structure managing all events.

  The overall program architecture looks like inside-out for me.

  For the buttosn, you must use action lock (switch not release!) and use the value changed events.

• Problem with the event

  Hello
  I am facing a problem with the events. Please Ref. Event.zip the attachment.

  AEv.vi is a LV2G used for the reading/Generate/Init/destroy the event. Test2.VI is a main vi (we must run this vi)

  The AEv.vi Init action must be done in the other vi (other than the Test2.vi:- but for the objective test I've initialized in Test2.vi only).

  Test2.VI is used for genetate event.

  I could have called statically AEv.vi inside the Test2.vi to generate an event... but the path that comes is decided when running... (I have many live similar to AEv.vi...) .. who decided at run time...)

  The problem:

  When I run Test2.vi, it gives me the error code 1 (try running test2.VI... it gives the dialogue on the occurrence of the error)...

  Can someone fix this?

  Thank you!

  I modified your screws to do what I think you want.  The way you did the user events will not work.  I added a line to send orders to Ev.vi

• Structure of the event: problem with data transfer

  Hello everyone,

  for three days I'm troubleshooting an issue in LabView with the event structures. I really hope someone can help here, because I can't find anything on the entire WEB.

  I had six groups of equal to a VI entry, each containing five checks enum (among others) where the user can specify some configuration of measurement data. I want the program to do is: to recognize if a any of these enum values has been changed and if yes, then submit the values containing the cluster in a subvi then calculates the wiring and affect the material of the ports. In addition, i need to submit the number of the enum element that was changed, so the program is able to clear the user input in the case of a breach (e.g. If the user sets two entries of enum control 1 meter and 2 Group 1 and then tries to set a third counter of entry to port 3, the program displays a message and deletes third entry as the number of entries of counter is limited to 2 per cluster).

  To resolve this problem, I used a structure of the event with 6 x 5 cases (change of enum value 1 Group 1 Group 1 enum value 2 change... and so on until the change in the value enum 5 Group 6).

  

  The problem is that if the user changes a value, the event structure reacts and performs the proper case; However VALUES of the cluster, the user changed are not subject to the SECOND time that an event occurs. It is a kind of a situation, "n-1". For example, if all five controls Enum of Group 1 are 'disabled' first and the user sets enum 3 of 'Meter entry', the structure of the event runs but submits the values previous to the Subvi (all enums 'Disabled'). When the user makes the second change, say that enum SWITCH1 to "Analog Input", the structure of the event is running again and passes the values of the FIRST user to the Subvi editing, then the Subvi gets data "enum 3 meter inlet and all other disabled enumerations.

  In easier words: if I have new values on my cluster "Kanal 1" (left side of the screenshot) and run the structure of the event, on the right side to "Kanal 1" indicator, I get the previous values (n-1).

  The structure of my event is in a while loop. If I create a timeout every 10 ms, and a loop of 250 ms the waiting time, I got the 80% chance that the recent changes are transferred to the Subvi correctly, in other cases I have a delay of the 1 step as described above. It seems to be directly based on the time that I specify the while to wait - but I can't explain it and I cannot accept a less than 100% chance to transfer the correct data, nor can I accept delays of a few seconds for each loop run. If I indicate timeout (infinite) get delayed 1-1 step values in all cases.

  When I specify cases of event to react on "all items value change" of the structure of the event behaves properly - but then I can't handle indicate which element has changed, as the CtlRef of output in case of a structure does not specify "enum 1, enum 2..." but only "Group 1".

  Does anyone have a solution to this? It is certainly a problem with the structure of the event, but I can't understand what to change.

  Thank you much in advance,

  Mr. Boiger

  This is because the terminal is read until the structure of the event runs.   Terminal is read, the event structure is waiting for an event.  The change in value.  Business events are running, but the value is the old value.

  Put the terminal inside the event.

  Or, you can display the connector called "New value" on the side left (stretching down from the border of the node 'CtrRef').  Use a wire one to come.

• Problems with .chart-field-background and event managers

  Hello. I am trying to add event handlers to my chart, so that the user can be allowed, click in the chart itself to perform certain actions such as moving, zooming, etc.. To avoid having to deal with the manipulation of mouse clicks that are not the card itself (for example on the axes), I found that:

  . Chart-field-background

  is the area which gives me all of the graphic and nothing else. However, when I move the mouse listeners in this region, the event is recorded only on half of the cells in the table. If you've seen the lack of available JavaFX graphic of background, you know that it contains lines in alternation of cells with a slightly different color. I found that only lines with lighter gray coloring record actually a mouse click on them, which makes me believe that dark grey cells do not form part of the background-field-.chart, but something else on top.

  For me, this is is a failure in the way the map regions are defined. Why can't I get a listener to work in the graphical overview and nothing else? Currently, the only solution seems to be to take the region:

  . Chart-content

  instead and calculate the difference between this region and the .chart field bottom to manually remove mouse clicks that are outside .chart-field-background.

  Someone at - it suggestions? This is true on the JavaFX Jira issue?

  Hello

  I'm not an expert on controls, but here is my suggestion based on your description: when you register an event handler on a node of "substance", it is called only when the mouse points to the context node - I assume that light gray is the transparent and gray with light gray cells background dark cells to fill. So the behavior seems OK - you can't wait for the events to be delivered at bottom when it is covered by the other nodes. I think you should really register Manager on all of the graph and filter events that you do not want to manage. However, this should not require a large part of the calculation of the difference between the regions, it should be possible to do just something like

  if (!background.contains(event.getX(), event.getY())) {
      return;
  }
  

  I hope that does not reach the bottom under the axes as well. Note that if there is the various transformations between the background and the node with the Manager on it, you may need to regenerate the coordinates of

  background.sceneToLocal(event.getSceneX(), event.getSceneY());
  

  And use the method that contains it.

• Problem with xfa.event.change in 3.3 XFA

  Hi all

  I found a problem with the way in which that XFA 3.3 treats the script below on a change event when a user more than 1 character in a textfield dough.

  sChange var = xfa.event.change;

  If ((sChange.length>1)) {}

  App.Alert ("Bad User\nCopy and paste has been disabled for this field");

  throw change

  XFA. Event.change = "";

  }

  XFA 3.0 the alert is sent, the change is eliminated, XFA 3.3, the alert is sent and persists the change.

  Any ideas?

  Yes, unfortunately, this is a known bug in Acrobat X and XFA forms.  He is currently in the study...  If you are targeting Acrobat or Reader 9.1 or later (not 10.0 or later), and then it works fine.
