Delete several event listeners.

Hello

In some cases, it is important to eliminate several event listeners in order to reduce the time CPU.

Below is the code btn [i] .removeEventListener (event.type, arguments.callee); to //x doesn't seem to work.

var btn:Array = (mc1, mc2);


main.addEventListener (MouseEvent.CLICK, click);

MC1.addEventListener (MouseEvent.Click, One);

MC2.addEventListener (MouseEvent.Click, Two);


function Click(event:MouseEvent):void

{

for (var i: uint = 0; i < btn.length; i ++)

     {

event.currentTarget.removeEventListener (event.type, arguments.callee);

x [i] BTN .removeEventListener (event.type, arguments.callee);

trace(BTN[i]); [object MovieClip] twice, including mc1 and mc2 respectively.

     }

}

function one(event:MouseEvent):void

{

trace ("mc1", event.currentTarget + event.type); [object MovieClip] mc1 click.

}

function two(event:MouseEvent):void

{

trace ("mc2", event.currentTarget + event.type); mc2 click [object MovieClip].

}

Note that if we put code event.currentTarget.removeEventListener (event.type, arguments.callee), inside the Click function, it removes the listener very well.

The problem may be with the table, but the trace in the loop of return [object MovieClip] twice.

No, except if you know or can derive listener functions references:

var btn:Array = (mc1, mc2);

var f: Array = [1, 2]


main.addEventListener (MouseEvent.CLICK, click);

MC1.addEventListener (MouseEvent.Click, One);

MC2.addEventListener (MouseEvent.Click, Two);


function Click(event:MouseEvent):void

{

for (var i: uint = 0; i

{

event.currentTarget.removeEventListener (event.type, arguments.callee);

BTN [i] .removeEventListener (event.type, f [i]);

trace(BTN[i]); [object MovieClip] twice, including mc1 and mc2 respectively.

}

}

function one(event:MouseEvent):void

{

trace ("mc1", event.currentTarget + event.type); [object MovieClip] mc1 click.

}

function two(event:MouseEvent):void

{

trace ("mc2", event.currentTarget + event.type); mc2 click [object MovieClip].

}

  • Removing event listeners - are they need all the time

    My goal is to increase the performance of my project, so I would like to know if it's always a good idea to remove event listeners. Specifically, let's say I have a movie with several scenes and several frames in these scenes. Each image has an event listener:

    Example:

    Scene 1

    Image 1 (EventListener)

    Frame 2 (EventListener)

    Frame 3 (EventListener)

    Framework 4 (EventListener)

    Scene 2

    Image 1 (EventListener)

    Frame 2 (EventListener)

    Frame 3 (EventListener)

    Framework 4 (EventListener)

    Questions:

    1. Flash continues to listen to an event in the scene 1/frame 1 when the playhead on stage 1 / 2 frame?
    2. Or Flash just listening events when the playhead is in a particular frame only?
    3. Should I remove the event listener once I leave a specific frame (should there be event listeners remove on each image)?

    You must remove event if listeners is no longer necessary.

    scenes do not yet exist in your published swf file.  they exist only in the ide to help you organize your project, but the more advanced flash users avoid using scenes because they do nothing useful, once you get a deeper understanding of flash.

    so, it makes no difference what the read head scene is because the flash player doesn't know which scene is that.  those who are righteous (marked) frames on scenario main and each scene begins with a keyframe void (unless and until you put something in that keyframe).

  • removeChild removes the object event listeners?

    Hello

    If you dynamically create a parent movieclip, dynamically add a selector of color of each element and add an event listener for each color picker, a removeChild on the parent movieClip removes event listeners belonging to one of her children?

    It should not.  You only delete the object from the display list, not existence.  It's still there, you don't see it, but you can bring it to life too fast that reuse addChild.

  • New in AS3: stupid question about event listeners...

    Hi all

    I am a newbie in Flash and have a question about event listeners. I have a site I'm developing with a movie clip navigation which is composed of several buttons. What is the right way to write the event listener?

    Here's a sample of what I have:

    I have a clip called 'buttons_mc' that contains the symbols of individual button with various names such as "btn_history". So far, I don't have an instance name for the clip of the film itself.

    My event listener:

    btn_history.addEventListener (MouseEvent.CLICK, history);

    I have to put something before the "btn_history" which refers to the video? I get this error message:

    1120: access of undefined property btn_history.

    Thank you!!!

    Julia

    Yes, it is preferable to have at least one layer dedicated to actionscript.  I often use a couple... one for code shared (functions and variables) and a level of the frame code (stop(), etc.).

    The code must be in a scenario where the button is directly accessible.  If your button is accessible in frame 1, which means that it does not animate in place such that it is not really intended to be used until you get somewhere near the bottom of the timeline, then you can target the button of the timeline that holds the buttons_mc movieclip.  So as I described earlier, if you give this movieclip an instance name of "buttons", and then to assign a code to the button on the inside you should use...

    Buttons.btn_history.addEventListener (MouseEvent.CLICK, history);

    But if the button exists somewhere down the timeline inside the buttons_mc due to the animation of the button, which means that there is more than one key image for the button, then you must place the code that you have initially shown in the last keyframe to the bottom of the timeline where he set the button in place.

    Click on an image and the successive images to press the SHIFT, or command key by clicking on the image to add it to the selection. Then Ctrl-click (tap two fingers) on any icon and choose to put in the trash. If the icons are in an easily selectable column or online, you can click on the window that contain, and then drag around them for a multiple selection.

    Shift-click or command-click to select if they are contiguous. Then press the delete key.

    Or select them and use the keyboard shortcut command + X.

    Or select them in the Index of the Timeline and use the key DELETE or command + X.

  • deleting unused events 10.1

    I just went through an extremely painful conversion of iMovie 9-> 10-> 10.1.

    I understand most of the things on the hard, but I'm still confused about a subject.  When I delete an event and some parts of this event are used by other projects, I get this message:

    All media files and projects to this event will be deleted. Extracts used outside this event will remain in your library.

    The thing that is confusing is the event will completely disappear, but projects that have used portions of the videos removed still appear to work.  Parts of the video clips used, stored in the project?  I read on iMovie 10 and she claims to use pointers, but still the manifestation disappeared.

    Can someone explain clearly, used video clips are stored and associated projects?  What happens when you remove the event?  In iMovie 9, he would remove the unused portions of the event but this sill has left the event and video clips used in your event library you may use later for other projects.

    Thanks, Greg

    There was a big change in iMovie compared to 10.0.x 10.1 which I did not clearly documented anywhere and confused me at first.  What I found by experimenting is that projects are not stored in the events but are now stored separately (separate files rather than subfolders in the event records are visible in a library).  Now, deletion of event deletes not all projects.  Original media can now be associated with a project - this is where the media goes if we hang out and falls clips directly in a project calendar.  Now there is also a new option to import "Media project".  The media from any source used in the project now appears under "PROJECT MEDIA" above the list of "LIBRARIES".   The media project, in contrast to the media in the events are removed when the project is deleted.

    From your experience, it seems that if we delete an event containing media used in the projects, the media concerned are transferred to the 'local' press of this project.  Of course, the original media files are not actually moved, only the directory structure is changed.  I did not test.  I guess that no matter what media in the deleted event, which is not used in any project is deleted.  Maybe you can check if this is the case (I don't actually use iMovie any more to FCP X).

    It seems that the message "all media files and projects in this case will be deleted. Clips u... ' is incorrect and should not forget the projects.

    I know it's just a warning and it doesn't seem to affect the performance of my computer that I can say, but I would like to know why it's happening.

    Well, I found the task that updates HPSA in Task Scheduler.  I disabled it by using the Properties window.  On the chance someone may be interested, I'll post how it turns out.

    I hope that I can now keep the HPSA listed for my computer with no additional alert to update again HPSA that generates several warnings and is not compatible with my desktop computer Pavilion p6 - 2220t and/or Windows 7 sp1 64-bit operating system.

    This disabled the HPSA update only not any other.  It seems to be a standalone update for HPSA.

  • Delete several bays

    I'm reading a text file. I have a simple question. I need to remove two rows in a table. I want to use the function remove the table. But I read that I can wire index only one entry. I have a total of 8 rows. I want to remove the first two lines of the table.

    Cited the help of LabVIEW, "you can delete several consecutive subdashboards both by the lengthof wire."

    Exactly how?

    Thanks in advance.


  • trigger several events to user in an architecture of producer/consumer

    Hi all

    I use a producer/consumer architecture, where the case within the property are selected with enums sent via a queue.

    Enums are queued in the producer, which is a Structure of the event inside a While loop. Then each of the events in the producer is associated with a case in the well (to make it easier).

    Now I would like to run several events in the producer, programmatically in a given sequence. The events involved in the sequence are basically all triggered by changing the value of a Boolean value (button).

    Please find attached a schematic representation of the sequence, I would like to implement.

    I heard of 2 solutions:

    -"Writing to the node (Sgnl) Value property of the variable [I] want change."

    -Dynamic user events

    In any case, I don't know how to make sure this is done for several events in a specific sequence?

    Thank you.

  • Trigger several events to a dynamically saved value of signage

    I have different controls for some pumps.

    I want to stop all with an emergency stop button.

    I use the event Structures to manage the user controls.

    In the previous version of my code, I register all events statically in the same vi. But to make the program compact and modular, in the attached version of the code, I use the references to the controls, and I go to a Subvi. In the Subvi I record the events of these references and I link the "event recording refnum" to the terminal dynamic events of the Structure of events.

    Everything works with the exception of the emergency stop.

    I can't use a reference of the emergency stop button to trigger the event, because the emergency stop opens the other files in vi for further confirmation from the user.

    When the emergency stop is confirmed by the user, I use the value property of a signalling to trigger the event stop of all structures event of the subgroup on the screws that control the pumps.

    Previously, I had only a single value of signage to trigger several events, but I saw that I have create the condition of critical competition and the Structure of events first, which handles the event, removes it from the queue, and other Structures of the event can't get the event.

    So, I use as signals of many boolean value pumps as much as I.

    But it does not always raise all events.

    Another detail, it is that I do not use the "Unregister for events function" in all the screws under that have Structures of the event. I saw no difference with this function, or without him...

    Apparently, Miss a clue of a general principle of LabVIEW.

    I join all of the template project.

    The main.vi starts the program.
