The dynamic expandable boxes - select all / deselect all

I have dynamic checkboxes in a Repeater.

I want to create a button to select all and clear all who will select each box and uncheck each box respectively. I'm hitting a wall.

Here is the code in the box:
< mx:Button id = "subCatButtonSelect" label = "Select all" click = "selectAll (); "/ >
< mx:Repeater id = "subCategoryPickerList" >
"< mx:CheckBox id = data =" {subCategoryPickerList.currentItem.subCategoryID "subCategoryCheckbox"} "label =" {subCategoryPickerList.currentItem.name} "width ="175"/ >
< / mx:Repeater >

Here's what I have to select all, which currently does not work:

private void selectAll (): void {}
var idx:int;
var len:int = subCategory.length;
for (idx = 0; idx < len; idx ++) {}
subCategoryCheckbox [idx] .selected = true;
}
}

"Subcategory" is a collection of ArrayCollection providing data for each checkbox.

Any help is appreciated! Thank you very much!

Hello Tracy,.

Thanks for the reply...

In fact, I got this working yesterday. I'm not sure how or why it suddenly started to work, but I did the test you suggested (subCategoryCheckbox [0] .selected = true; a button) and debugged/tested all the individual lines of the function, and it separated. (Yes, the dataProvider for the Repeater is assigned elsewhere - good question however).

Thanks again for your help!

  • How could I add together the numerical values in the dynamic text boxes?

    I do an application and I currently have sections such as travel, rent, etc., where you can press one of two buttons to increase or decrease the total number (fresh) for this article. All totals are displayed in the dynamic text boxes - here is an example of the code for a section-

    var FoodAndDrink:Number = 0;

    button1_btn.addEventListener (MouseEvent.MOUSE_DOWN, Add);

    function Add(e:MouseEvent):void {}

    Repasetboissons += 1;

  • Value display trace in the dynamic text box

    Hey just work on an exercise and I can't understand the code to display the value of the trace in a dynamic text box.

    The following code generates exactly where I am at this time.

    Import 12345678910111213import;

    import flash.text.TextField;

    Basic color picker (based pixel)

    var myColourBitmapData:BitmapData = new BitmapData (500 400, false, 0xFFFFFF * Math.random ());

    var myColourBitmapImage:Bitmap = new Bitmap (myColourBitmapData);

    Add to list

    addChild (myColourBitmapImage); Add to the scene

    Get colors

    var pixelValue:uint = myColourBitmapData.getPixel (85,62); color of the pixel at X, Y

    displayed in the output window

    trace (pixelValue.toString (16)); toString (16) converts uint in a number of Hexadecimel format

    Here are a few screens, I want the values of trace output to appear next to the text in the dynamic text box

    Picture 4.png

    Picture 6.png

    I'm not sure of how to call the pixelValue to my text box, any help would be appreciated!

    Before or after the line that begins with «trace...» ' set dynamicTextFieldInstanceName.text = pixelValue.toString (16); Replace dynamicTextFieldInstanceName with the actual name that you gave to the dynamic textfield.

    There is an error in your output window. It seems that you have not integrated a font in the dynamic textField.

  • Script check boxes 'select all '.

    I would like to create a box on my form which, when checked, automatically checks several other boxes. Select all / deselect all, if you want to. No idea what javascript code that would accomplish? Thank you.

    You can use something like this as MouseUp event of (main) - box:

    this.getField("Check Box1").checkThisBox(0, event.target.value!="Off");
    this.getField("Check Box2").checkThisBox(0, event.target.value!="Off");

  • Remove the overpint on the entire document using select all

    Is there a way to remove overprinting of attribute on an entire document? The problem is when somehitng else is in the selkection in addition to a vector path, and I want to do a select all.

    Tried, but does not work

    1. In the links palette, highlight all the links
    2. Click to access the link
    3. CMD 3 to hide
    4. Select all

    Must be something else in addition to related images that cause the atrributes boxes to be gray.

    Here is an example below of something which would have badly separated, without lifting with the overprint Preview on.

    Screen shot 2011-11-09 at 1.23.26 PM.png

    Maybe you can try this, Mike:

    Select one of the images [raster]. In the menu select choose same > appearance, and then choose the command selection > Inverse and that I hope will work so that you can erase the overprint with one (or two) click (s).

  • List box select all

    How can I select all the items in a list box.

    The box is filled with the other buttons. Then when I save the form and collect responses, to the item is selected. So I need to have ALL selected by default.

    I'm assuming that when you select items in the ListBox control by hand they appear onn the right data file?

    Here is an example that shows how I did it... unless I'm not understanding what it is you are looking for.

  • The dynamic Types shows not all objects in the inventory

    Hello

    I thought I'd have a look at the new feature of dynamic Types in vCO 5.5.1 after falling on this tutorial: tutorial dynamic Types: set up your own Twitter plugin without any script, however - I ran into a bit of a problem.

    So I downloaded the plugin generator of dynamic Types package and run the creating a new plug-in (namespace and corresponding REST host) -it went very well and created the namespace and the REST host as planned.  I then ran the create a new type of plugin and followed through the forms of user interaction and validated all of the received data - it also has been correctly performed.  My only problem is, no instance of the type created is displayed in the inventory - and there are 100% at least of 4 objects returned by our REST API.  When I manually run the COE-> plug-in-> plugin generator dynamic Types - methods - > FindAll I see in the newspapers that it deploys the correct objects with the correct id/name - why these objects are not displayed workflow inventory?

    So this package that I thought I would use the provided standard workflow with dynamic Types plugin, so I added names/type space and automatically generated stubs of workflow for the type.  Then I went into each of these heels of workflow and filled in the script of "To-do" with the code to set the appropriate output, for example the workflow xxx.xxx find all uses the host REMAINS appropriate for an array of objects API JSON, and then iterates through these objects and calls the method DynamicTypesManager.makeObject () , before finally pushing them into the output array.  However, this does not show all inventory items is.

    In both cases I rebooted namespace of the inventory several times and nothing.  It seems that the DynamicTypesManager.makeObject () merely create the object in the local scope that I can see to create types of objects/correct data using System.debug, yet they do not arise outside the workflow and in token of workflow attributes, they remain unset.

    There is something really obvious that I'm missing? / someone at - it suggestions?

    Thanks in advance!

  • How to get the name of the instance of button to display in the dynamic text box

    first of all, thank God for you people. Laughing out loud.

    Here is my scenario, I am the designer of consumate and learning coding by leaps and bounds, today its been a lot of stumbling blocks however.

    I have a site I designed that contains buttons that navigate the user at various points on the timeline using image tags. When they arrive at the appropriate image tag, they are presented with a movieclip containing two layers. The bottom layer is a card, and the top layer is a collection of buttons printer having a component tooltip on them showing you the information on detailed mouse printer on and takes you to the Remote UI printer on release. each button has a name of unique queue for the printer appropriate under its name of the instance (e.g. itm100_btn). Here's the jist... I want to be able to place a dynamic text box near the printer and using action script button it display printer queue name automatically simply based on the button, targeting, or even place the dynamic txt area inside the printer button mc. See, on some pages, there are like 24 printers... I'm AFRAID to have to put all these names in manually because there are total 150 printers! OUCH...

    Oh it is AS2.0 with Flash cs4

    In short... God bless you people... for the love of God someone help me? Laughing out loud.

    Thank you so much peoples!

    "I make things look purdy, but do not know why the sky is blue".

    to create a movieclip button:

    create a (insert/new symbol/movieclip) movieclip and attach a stop() to its first image and etiquette 'up '.  create any graphic you want for the up state button movieclip.  create a 'more' and, if necessary, a "low" setting

    When you place this button movieclip on stage give an instance name (for example, printer1) and use:

    {Printer1.onRollOver = Function ()}

    this.gotoAndStop ("over");

    }

    {Printer1.onRollOut = Printer1.onDragOut = Function ()}

    this.gotoAndStop ("up");

    }

    {Printer1.onPress = Function ()}

    this.gotoAndStop ("down");

    }

    and add your onRelease to do all that.

    If you also wanted to add a textfield that displays the instance name of the button when the button is postponed, place a textfield on the framework of the "over" and give it a name instance (say tf) and associated to the MovieClip "over" frame that uses:

    TF. Text = This._name;

  • Roll on the dynamic text boxes

    When I have a dynamic text box in a movie, and I want the movie she buttonMode. The hand symbol is converted to an arrow, even if the text is not selectable. Is there a way to get around this? It is not to do with a simple button... so I can put the text into a single button, but I expected something a little more forward.

    I do not see this behavior, but you can use the mouseChildren property to disable the children of your movieclip to respond to the mouse.

  • Add price and display them in the dynamic text box

    Hey,.

    I have a combobox with specific prices and radio buttons I want attached according to the choice of the user. I have trouble to get the application to add the total of selections and display the total in a dynamic text box.

    I try to use global variables. I put them to a certain value depending on what is selected. At the end I put add them upward in the total variable and which corresponds to the text box named totalPrice.

    Currently, the value of global variables is not returned to their duties.

    Any suggestions for how to do this correctly?

    Thank you!

    remove these return statements, create a function that updates your textfield totalPrice and call this function of objComboListener.change after your if-else statements.

  • get rid of the area around the dynamic text box?

    I want to make my text 'grabable' on my swf as a way to do it, I was thinking the whole dynamic of the text, is it a good idea? If so, how can I do so that the box appears around the text? Thank you, Raphael

    The text should not be dynamic to make 'Selectable' - is an option to the widow of properties. Click your text and in the Properties window, click the 'Selectable' - it's an Arelatifs capital and b small nail beside him: Ab (the b is white in a black box). The text has a box around it, because you did have it's icon two courses on the right of the icon 'selectable '. Click this icon to remove the box.

  • Definition of the size of the image in the dynamic text box

    I have a dynamic text box in which I'm embedding an image.  The following code fills the text box

    infoBox.informationText.htmlText=
         "<font size='16' color='#FFFAF0'>"+calledMarkerIndex+
         "\n<font size='14' color='#FFFAF0'>"+calledMarkerDate+
         "<img src='http://jacobull.files.wordpress.com/2010/06/ween.jpg'/>"+

    How set the size of the image in the code above.  I tried to insert the width and height parameters after the path of the image, but an error is generated.  I would like for the width of the image to be as wide as the text of infoBox.informationText Dynamics

    Any suggestions?

    Also the path to each image corresponds to a variable called calledMarkerContent how could put the img src is equal to the variable called calledMarkerContent?

    Hello J,

    If you use a component to scroll, you can eventually use the ScrollPane for movieclips instead.

    The Adobe AS2 components reference:

    " The ScrollPane component to view video clips, the JPEGs and SWFs in a scrollable area. Using a scroll pane, you can limit the amount of space occupied by these types of media screen. The scroll pane can display the content loaded from a local drive or on the Internet. You can set this content during programming and execution with ActionScript. "page 1093 "

    This way you could integrate the area of dynamic text (for your text) both the movieclip (which has the text for your image inside box) that you can then scale them both in an another movieclip (parent), you use the ScrollPane component on.

    This way your text in dynamic text field dimensionnera not, the image can be scaleed to the size of what ever you like (dynamically) and if the two are sitting in a parent movieclip, this parent movieclip may have a ScrollPane component on it.

    How does that sound?

    Best regards

    Chris
