Capture events TreeField

Hi all.

Here's my question.
I use the tree to organize my audio files that are stored in a vector, which is located in key/value pairs.
I have a single tree that is built with N parents, each parent has K children.

Now the behavier should be as follows.

A click on the parent user expands the chidren.
This is the default behavier and it works fine.
When a user clicks on one of the children, an event fires that is taken by the listener.
Which works very well also. I can override the TreeField class method to achieve that

protected boolean navigationClick (int status, int time)

One reason more why Im doing this way, because I don't want the application menu is displayed when there is a click on the tree node.

Finally, I ran into a problem, detect what child node receives the click.
I need to know its name or a relative position within the tree to act on this.

getCookie() method of the field class don't is not set up so that it only returns a cookie for the TreeField class not for nodes in case
you try to catch the FOCUS_GAINED event and information about the object that gets the focus. Did not work for me, since I can't always not detect what node or the subnode sends the event.
in any case, I tried to hack it left and right, up and down with no luck.

The above method

navigationClick (int hour, int status)

catch the click but it doesn't provide any info on the properies object that raises the event.

If it's a button field or any other field I use

public void fieldChanged (field field, int context)

no problem, u check the field object and your Button object for equality and you're in business, but not with the TreeField or
He me MISSING something here because of the Ecplise of my brain

Thank you and sorry for the long post.

Thanks to you all. I got it for the time being it will solve my problem, but nonetheless I don't think it's a good

TreeField myTree = new TreeField(myCallback, TreeField.FOCUSABLE)
              {
                         //override Field Class method to  detect when user clicks on the field
                  protected boolean navigationClick(int status, int time)
                  {
                       switch(getCurrentNode())
                     {
                      case 1: // your action goes here
                      break;       

                              case 2:
                                 break;
                                  ......
                      }

                      return true;

                  }
                     };

capture event c#

Hello
It is possible to capture the event and trigger the action? The final document, the message box say 'Bye '.
I can do using the SDK with c# If yes then please guide me how. If NOT, let me know how it can be possible.
Thank you

Not with any c#, no it isn't. You must either use JavaScript

(embedded in the PDF file) or a custom plugin based on C++.

Is there a way to capture events on a button (or output) when a window IMAQ is currently developed?

I was a sad panda when I realized that the IMAQ window does not appear to pass key events down to the control panel of VI. Is it possible to retrieve these keys and handle their events? I'd rather be able to use the features of labview directly with the keyboard while a window IMAQ is developed as opposed to moving to the front of labview control.

Thanks for the help.

-Chris

Hi Chris,

the functions of the input device should help you. You can query the keys, and react on them. Another soultion is to use a dll that receives key events and send them to your vi.

shipping/capturing events of an itemEditor

I have a custom itemEditor which creates a ComboBox for use in a datagrid. I wish I could send a change event in the itemEditor until the parent containing the datagrid control. See attached example.
Thank you!

capturing events?

Hello
So, I throw an event from my window title roughly when it closes.
I had it on some components 'disconnected', follow these steps:
addEventListener ("newSiteSave", newSiteSaveEvent);
who forwards my title popup event window.
But my other component never see / catches this event any idea?
I expect as if any component dispatches an event, you can intercept the event anywhere.

All pop - up is related by SystemManager so plugs event command in your panel2 who is sent by the TitleWindow.You button will add the listener on systemManager instead
```
this.systemManager.addEventListener('siteEvent',listener)
```

Flex events: when to use the capture phase

Greetings!
I think I understand the event stream (maybe I didn't), but have trouble understanding
Why should I use capture phase event in adddEventListener? Can anyone think of use cases?
Why would create custom with capture event is not bubbling as default?
Concerning

Because all levels of the tree view allows you to see the event and it

requires you come up with the name of unique events. Basically, it breaks

encapsulation and takes more time for the process.

You might want to watch how other application infrastructures set up their

controllers.

Copy a structure of event containing local variables

Hello

I am a state machine design in Labview and next state transition logic to wait be clicked a few buttons on the Panel.

If I press a Boolean button from 1 to 9, next State should be X, otherwise condition (10 to 16 tags) should be there.

I thought that the right approach, because it would be a structure of the event, where I added two cases: case 1 (button 1: mouse to the bottom button 2 down,..., 9 of the mouse down) and box 2 (10 mouse buttons down,...). For each of these cases, I'm reading & writing the local variable of some double digital.

When I copy the structure of the event in another case of structure of outer case, I note the following: all cases in the event loop is missing, and the local variable renamed automatically and a new created indicator digital.
- How to make an exact copy of the structure of the event, without the problems described above?
- Could you suggest a different approach more effective than mine?
Thanks for any response.

Start by reading the guard and recommendations for using events in LabVIEW - LabVIEW 2011 help

The fact that you try to copy and structure of the event to another, and that a structure of the event will be buried in a case initially tells me you are already heading on the wrong track and yourself in creating a world of problems. Your architecture will never seem to work for you.

The event structures are always active and capture events. Even when the structure of the event is not in the path of execution, it's queue of events to which he attributed to him. If you have events that are set to lock the façade until full, then you're really screwed because the event structure will capture the event, locking of the front panel and the execution path of your code with the state machine may never come to the specific case that has captured the event to support then release the façade.

In general, you should have the structure of a single event in a VI, and should not be buried in a case structure where he can never carry. You also shouldn't have several event facilities manage the same events. These are not hard and fast rules, but until you are quite familiar with how the event structures work and completely understand the architecture of your code, you should not violate or you will just ask trouble.

Similarly with the help of local variables. The fact that you say that you have local variables and you try to copy tells me that you already have too many. There is certainly a better way to build your VI, which does not require local variables with the exception of a few cases and certainly won't need several structures event buried in the structures of the case.

You should probably have a producer/consumer architecture that handles the events. Have a simple loop with a structure of the event which captures all user interactions. Pass events to a loop of consumer who is also your computer through a queue of State. (Also known as a computer state in queue or the BAU). Let the state machine to determine how to manage the events, he received based on what is the current state of the VI.

Using the Structure of the event in a Machine of State Enum

Hello!

I'm new to labview(~10 months). I tried my best to search on the forum/net but didn't have an explanation.
I simplified the code to show the problem. I'm using Labview 2013 worm 13.0f2 (32 bit).

The "EventStructure_Trigger_in_EnumStateMachine.vi" is a State Enum machine.
The "resting" State contains a structure of event that detect evnet of changing value of 3 buttons:

Do something touches: simply show something of the display flag
Start Run button: bring the program into "run" State
End key: put the program in the 'final' State and then close it

The State of 'run' is a time loop that will be stopped only by clicking the 4th button - button stop running and bring back the program in case of 'lazy '.

The problem is to "run" State, any click on irrelevent buttons 3 (buttons only detected by the structure of the event in case of 'lazy') will make the program crash.
By comparison, I create an another vi attached as 'WhileLoop_in_EnumStateMachine.vi', which is almost the same except that the event structure is replaced by a while loop (and do something key has no function). In this vi, everything works well - by clicking the irrelevent buttons will not crash.

I can't understand why.

P.S. I failed to attach .vi onto this post... a zip compressed instead.

A problem that resembles yours: http://forums.ni.com/t5/LabVIEW/why-does-simple-case-structure-code-hang/td-p/3176592

I think that the response of Stuart will help you understand how your code handles this situation.

You must manage your events outside your main loop to your structure to operate on any captured event.

separate the event

can someone give me a resolution how can I separate my events without using the struct event.

what I need in my program not only separate manifestations, but also I can not go to another event if the front test is not yet finished.

traorepaul

I guess that you keep your code inside the structure of the running event. Usually what you should do is using the structure of event only capture events and passes the event to a state machine running in parallel. You could search for event based model of machine design State for more idea. Also its best to show the code you did

Click event of ListField Probem with the navagationClick

Hello

I want to capture the envent of click on a listField.

in my screen, I had other compents as ButtonFields and RadioButtonFields.

I capture events of these elements.

to capture the click on the ListField event, I first tried this solution:

Click on a file in the list ltDossier *.
protected boolean navigationClick (int status, int time) {}
if(Status == KeypadListener.STATUS_FOUR_WAY) {}
int iselected = ltDossier.getSelectedIndex ();

Selected string = (String) myCallback.get (ltDossier, ltDossier.getSelectedIndex ());
csDossier ocsDossier = new csDossier();
ocsDossier = vectDossier.elementAt (iselected) (csDossier);
int id = Integer.parseInt (ocsDossier.Id);

If (id! = 0)
{
Dialog.Alert ("file selected:" + id);
}
on the other
{
Dialog.Alert ("no file selected");
}
}
Returns true;
}

My probem is that this works well if the Listfield is the only component on my screen.

so, I tried this alternative:

FieldChangeListener listenerltDossier = new FieldChangeListener() {}
' Public Sub fieldChanged (field field, int context) {}
TODO self-generating method stub
Dialog.Alert ("click on listenerltDossier");
}
};

ltDossier.setChangeListener (listenerltDossier);

But it does not work.

Can someone help me please?

I found this solution:

protected Boolean navigationClick (int status, int time) { If(status == KeypadListener.STATUS_FOUR_WAY)}

{

if (rbTous.isFocus ())

{

rbTous.setSelected (true);

rbSelected = rbgFiltre.getSelectedIndex ();

}else If(rbTraites.isFocus ()) {}

rbTraites.setSelected (true);

rbSelected = rbgFiltre.getSelectedIndex () ;}

else if (rbATraiter.isFocus ()) {

rbATraiter.setSelected (true);

rbSelected = rbgFiltre.getSelectedIndex ();

}

else if (btRefresh.isFocus ()) {

switch (rbSelected) {

case 0: pushScreen (new ExpertiseScreen (0));

Close();

Init_ltDossier (0);

Break;

case 1(ushScreen)

new ExpertiseScreen (1));

Close();

Init_ltDossier (1);

Break;

case 2(ushScreen)

new ExpertiseScreen (2));

Close();

Init_ltDossier (2);

Break;

}

}else If(ltDossier.getSelectedIndex ()! = - 1) {Dialog.alert ("index =" + ltDossier.getSelectedIndex ());}

}

}

return true;

}

It seems to work.

Events of the Bluetooth headset.

Hello

I'm doing some R & D for a Java application.

I want to know if it is possible to capture events generated by the keys of the headset bluetooth as 'Back', 'Forward', "play", etc., if the keys are available on the helmet.

If so, how it is done.

I know that we can route the audio to the headset using AudioPathControl. Iwould want to know - is it possible to control the application with the helmet.

Any sugestion/commnet is welcome.

Thanks in advance.

Thanks for the reply!

Custom ItemRenderer and event Bubbling

I'm targeting Flex 4 on Air 2, but I don't think it changes the answer to this question.
I have a spark DropDownList I wrote a custom itemRenderer. In my item renderer, I have a spark.button. I have links to events in the mxml and target functions in the respective classes, and I'm listening for the dropdownlist change event and my itemrenderer.spark.button click event.
My problem is that I can't get any event in my fire element converter. It of like when I'm clicking the button, it triggers the dropdownlist.change event and destroyed the itemrenderer until it can handle the click event. So I thought that maybe I could solve this problem by adding listeners have rather than use mxml binding but same problem. Finally, I just put a trace in the click event of mxml and nothing. It does not with the item in the list before get rid you of the list.
So, simply, how to capture events itemRenderer before allowing the DropDownList change event? Or why the click through button and cause control dropdownlist to destroy?

It looks like uses DropDownList MOUSE_DOWN and no CLICK, which is why he

close the drop-down list before you get your click.

I saw a property hitAreaAdditions, you might be able to access the areas of block

close the drop-down list, but you might want to just meet MOUSE_DOWN

and stopPropagation on the event.

Hello George,.

It is a diagnostic tool for Apple. In my view, that it captures information of your network connections. Or at least, that's what it is designed to do. I took a quick glance at my 10.11.6 machine and the framework of the CoreCapture seems to refer to an internal tool of Apple to ' / usr/local/bin/cctool. " Maybe that's why it crashes for you. See /System/Library/PrivateFrameworks/CoreCapture.framework/Versions/A/Resources/co llectWiFiDebugInfo.py

I have no idea how you can solve this problem. Maybe you could create an executable shell script in this way just to see if that allows what is running to complete.

You should definitely file a report bug with Apple in this regard. Maybe it will be fixed in a few months.

Add the waveform does not reset

Here is the explanation of high level. I want that samples of 100 Hz, groups of 10. I like to check to the discontinuities and then take the last data point in each group of ten. Then take this last datapoint so I 1sample/s if all goes well. Add to the top of my 1 s/s at a "rate of scanning in seconds" (generally 15 sec) and if there is no anomaly data, take the last data point and write it to the file. If there is an anomaly, I want the typical scans over an additional column of the event recorded in the 100 s/s complete.

Specifically, I use the subset of waveform get successfully, I think, but when I Append Waveform, the timestamp is stripped. I was about to try to get XY waveform, but I thought this announcement on the forums might make me come more quickly than the obstinate by it. So how can I easily draw the last data point in these subgroups with success?

I'll take other ideas, too. I seem to get popped up on little things like that. Also, you'll forgive the mess. It's a work in progress. Thermal cycling rig 02/08/13 v2.vi is the code base and TDMStoExcel and RunMacro live can be deleted if you try to run it. they work

Thanks in advance

the loop is just to remove the ten sets of ten, resulting in a bit rate a second base. This way I can run a 'scan in seconds rate' for the while loop with the ability to capture events at 100 Hz. I solved the problem of the table do not reset using the auto index function. I had Dale this initially because, when I develop the process of data for all channels, I didn't know how it would affect waveform bays. I didn't manipulate 3d tables if I could help him. not my forte. Then, I'll try the subarray of waveform get nine full channels and see if it works. After that, the receipt of the data. I need to write to the file for nine channels and hopefully not wait to write until the dump event data. I want to tick away at the speed of scanning and then create an additional column only if there is an event. I'm trying to capture functions to void / screws. the first Subvi process data will do much limits responsible Boolean logic check of the control of movement.

The example you gave is a great idea for the logic, I would like to implement. Thanks for the suggestion!
