How can I access all instances of the itemRenderer in a specific DataGridColumn?

How can I access all instances of the itemRenderer in a specific DataGridColumn? Or, if I have a rowIndex and columnIndex, how do I get the itemRenderer to these clues?

I use States to change the display of my itemRenderer of a TextField of a PopUpMenuButton. What I was trying to do was change back the display of all the other itemRenderers visible in the column of the textfield, when one of the itemRenderers displays the PopUpMenuButton.

I tried to loop through all of the itemRenderers in the column and casting them as the class I was using and then by setting the currentState, but, it wasn't good performance wise and required too code. I simplified it listen to a change on the listData owner event (in my case a DataGrid, but any component ListBase) and by setting the currentState to null when it is triggered. Works like a charm.

  • How can I select all instances of a component in the timeline at once without manually shift clicking on each instance?

    Title says it all!

    How can I select all instances of a component in the timeline at once without manually shift + click each instance?

    The reason why I want to do this is because I have a video clip with MANY quick cuts. So the clips are cut out and splattered everywhere. I'm color correction now and so I want to be able to select a clip around wherever it exists in the timeline so I can drag the effect on all the at once, without having to search each occurrence of the item in the timeline panel. This lot "select" would make it so I don't miss not all instances of the clip and saving a ton of time going through the timeline and Shift clicking whenever the clip is also up.

    I hope that the PP is smart enough to do this

    Thanks in advance!

  • How can I access my emails after the death of my PC. I had a pc using Windows Vista and I served my Windows Mail e-mail program.

    Disaster of Windows Mail.  Where are my emails please?

    How can I access my emails after the death of my PC. I had a pc using Windows Vista and I served my Windows Mail e-mail program.  The computer has stopped working so I removed the hard drive, put it in a case and now use it as an external drive.  My new computer, I took possession of the Documents and Settings folder, and I'm looking for emails.  I followed the path, Documents and Settings / / AppData / Local / Microsoft / Windows Mail but there are 2 folders, backup & stationery as well as a few small files.  Where I could hide my email? Please, I beg you.

    There should be a directory called local folders under the message store and eml files organized into folders named after the directories under this directory are.  They may be hidden files, so make sure that you have enabled the display of hidden files and folders under control panel | Folder options | View.  You can also try to search *.eml, because messages are stored as eml files.  See www.oehelp.com/backup.aspx#wm for background.

    AJ,

    You only have access to Cloud applications creative that you pay, so all you pay is what's available for use. Because you used a new application, there is no unexpected to your Bill change.

    If, for example, you use the Photoshop photography program, you will have access only to Photoshop and Lightroom. If you opt for a single application, you pay and have access to this unique application.

    If you opt for the full creative cloud, you have access to all of the following at one price, regardless of how many applications you actually use. You can an app, three applications, or all of them: complete creative cloud is still the same price.

  • How can I combine all pages of the site to a new page of the site?

    Hello

    I use Dreamweaver cs4 on a windows pc. I have 12 pages of my site with a spry vertical navigation bar. Whenever I create a new page I then add that to the spry navigation bar. All other pages do not show this new page in the navigation bar. Thus, the spry NAV. must be site wide update. Is it possible to update the spry navigation bar site wide in a few clicks? Is there an easy way of all the other page a link to this new page? I have a rendering template, but all pages on my site are now detached from this model. Whenever I saved the template in an html file to create a new page in the navigation bar was the word inside template, so I just deleted it out of the code. As you can probably I'm pretty new to dreamweaver so any help will be greatly appreciated to say the least. I checked everywhere wherever I can think of for the answer

    Thank you for taking the time to help, dluthier

    Is it possible to update the spry navigation bar site wide in a few clicks? Is there an easy way of all the other page a link to this new page?

    Yes, there are ways to have all the pages to be updated when you make changes to a navigation bar.  However, the way you describe the situation you currently do it all manually.

    The easiest way to update a navigation bar:

    1. the use of serverside includes: this is a basic tutorial explaining what is a SSI and how it's done.

    http://bignosebird.com/SSI.shtml

    2. the other is the use of models - that you tried.

    I have a rendering template, but all pages on my site are now detached from this model. Whenever I saved the template to a file html to create a new page in the navigation bar was the word inside template, so I just deleted it out of the code

    That's where you went wrong, you save the template with a new name, and save it as an html file.  You must use: Create New > model.  This way, you create a new page of the master model and save it in the root of your site - and this is what is called a "page of the child".

    Using DW templates:

    http://www.Adobe.com/devnet/Dreamweaver/templates.html

    The differences between the use of SSIs and DWTs (template file):

    With a SSI file, you make changes to the file and all the pages, the inclusion of which will update automatically and you need only download a SSI whenever you make a page.

    If you use a model, whenever you make a change, once again all children pages are updated, but you need to download * all * changed pages.

    I hope this helps.

  • How can I reload all tabs in the order?

    It used to be (on older versions of Firefox to 11), after working offline, I put online, right click on the tab to left-handmost and click on reload all tabs. Then, I get a message saying: it is necessary to return and that all transactions will be done again. I camp on the button enter to confirm and all my tabs loaded successively from left to right.

    In some sort the Versions 11 and 12, when I do the same exact things, the sequence of loading my tabs get involved.

    What happens and how to prevent this seemingly random load of tabs? It is important in the game that the sequence remains intact.

    Thank you.

    I have it! Proceed as usual, but before reloading all tabs go to each tab, see how try it again once the button is highlighted with a grey outline of lil? Press tab on the keyboard to turn off highlight them and then go.

  • How can I access a variable on the main timeline of a movie nested in HTML5 Canvas

    Hello

    This should be pretty simple, but for some reason, it does not work if I have the wrong syntax.

    But I have a movie clip with a bit of code in it.

    It is a timer.

    I want to be able to program the wait time: since the main scenario and that the timer read this variable on the main timeline.

    I implemented the delay var = 1000 on the main timeline, but then I do not seem able or knows how to get this variable in my code in the nested MC. It is quite difficult to find the reference of the paradigm flash timelines on H5 support pages, so I really appreciate the help.

    tl2 var = this;

    TL2. Stop();

    var delay = delayMain;

    var startTime is createjs. Ticker.getTime ();

    createjs. Ticker.addEventListener ("tick", f);

    {function equation

    If (createjs. Ticker.getTime () - startTime > delay) {}

    TL2. Play();

    createjs. Ticker.removeEventListener ("tick", f);

    }

    }

    If you want to get to a variable defined by a feature any at any depth, you can use the window. As:

    Window.Delay = value;
