How to create table of controls (Images, buttons) in ActionScript

Hello!

Could someone help with ActionScript and Playbook SDK?

How can I create a two-dimensional array of controls (buttons, images, text fields) in ActionScript?

And how do I use radio buttons in ActionScript?

Hey,.

keys and parts do not have ID like in html and javascript. That being said, its impossible to do it like that. the best approach is to create your own class that extends the LabelButton (or whatever component you need) and have an id property that is implemented. so, you can set a code personal to her. I've implemented what you asked below. You can apply this to other components as well enough to make changes to the class and modify the extension. Here is the code:

LabelButtonTest.as (main application class):

package
{
    import flash.display.Sprite;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.events.MouseEvent;

    [SWF(width="1024", height="600", backgroundColor="#CCCCCC", frameRate="30")]
    public class LabelButtonTest extends Sprite
    {
        private var myButtons:Array;

        public function LabelButtonTest()
        {
            super();

            // support autoOrients
            stage.align = StageAlign.TOP_LEFT;
            stage.scaleMode = StageScaleMode.NO_SCALE;

            /*
             *  Initialize your array of 2 X N (in our case we will be using 10)
            */

            myButtons = new Array(new Array(), new Array());

            /*
             * Now we set up our array, first doing the first row and
             * set up 10 buttons with their own ID using the constructor
             * for our custom class CustomLabelButton(ID)
            */

            for (var i:int = 0; i < 10; i++)
            {
                var myBtn:CustomLabelButton = new CustomLabelButton(i);

                myBtn.label = "Button " + i;
                myBtn.setSize(100, 50);

                myBtn.addEventListener(MouseEvent.CLICK, onClickEvent);

                myButtons[0].push(myBtn);

            }

            /*
             * We do the same for the second row of buttons, starting
             * with 10
            */

            for (var i:int = 10; i < 20; i++)
            {
                var myBtn:CustomLabelButton = new CustomLabelButton(i);

                myBtn.label = "Button " + i;
                myBtn.setSize(100, 50);

                myBtn.addEventListener(MouseEvent.CLICK, onClickEvent);

                myButtons[1].push(myBtn);
            } 

            /*
             * Finally we cycle through our arrays and add them to our display
             * this wil produce two rows of 10 buttons going accross
             * each when clicked will call the funciton onClickEvent and
             * trace out their ID to the debugger
            */

            for (var i:int = 0; i < 10; i++)
            {
                var myBtn:CustomLabelButton = myButtons[0][i];
                var xPos:int = (i * 100) + 10;
                var yPos:int = 10;

                myBtn.setPosition(xPos,yPos);

                addChild(myBtn);
            }

            for (var i:int = 0; i < 10; i++)
            {
                var myBtn:CustomLabelButton = myButtons[1][i];
                var xPos:int = (i * 100) + 10;
                var yPos:int = 60;

                myBtn.setPosition(xPos,yPos);

                addChild(myBtn);
            }

        }
        public function onClickEvent(e:MouseEvent):void
        {
            /*
             * Print out ID of the button thats clicked
            */
            trace("the button ID is: " + e.target.id);
        }
    }
}

CustomLabelButton.as (our custom label with the ID property button class):

package
{
    import qnx.ui.buttons.LabelButton;

    public class CustomLabelButton extends LabelButton
    {
        private var _id:int;

        public function CustomLabelButton(num:int = 0)
        {
            super();

            id = num;

        }
        public function set id(num:int):void
        {
            _id = num;
        }
        public function get id():int
        {
            return _id;
        }
    }
}

run the code and see how it works. I hope that's what you're looking for. Good luck!

  • How to create a custom control for a button where the look apply to everyone else but not the Boolean text?

    Hi all

    I would like to create a button custom as a master, so that if I change the look of the master all other buttons are changed.

    I did it with a custom control, such as a 'type strict def' otherwise the look will change , BUT if I do this as a strict type def I can't change the Boolean text more which should be different on each button.

    How to create a master control of a button where the look apply to everyone else but not the Boolean text?

    Steve Chandler wrote:

    I don't think that you can do. I just looked and as I suspected the Boolean property text is read only for strict typedefs, you cannot use the nodes property to change the text.

    As a just solution make it a typedef. When you want to change the open look the typedef and strict rendering, make your changes, then make no strict again. You will need to update the text Boolean yet once for all instances. Kind of pain. This is perhaps something for the exchange of ideas.

    Alternatively, remove Boolean text and replace with legend

  • How to create a digital control (of any type) which can be increased or decreased by a 'unit' at the same time?

    As in the title.  I want to create a digital control (no current limitation on its type) with a range of 1 to 10 (and a step of 1).  The only difficulty that I have, is that the user should only be able to increase or decrease 1 at any time.  Code initiated by this change of value must have completed at least once before that the value can be changed again.  This is because code of VI is mainly contained in a while loop and control are read once at each iteration and its last value should not differ more than 1.

    Is this possible with LabVIEW 6.1 and if so, how?

    One of the solutions that I came up with so far is to disable the control immediately after its reading, and to turn it on again immediately seized is read the next time (I have to assume that the user is unable to click twice before the control is disabled).  It is an acceptable method, or is there a better way?

    I also had an idea of partially disable a normal digital control, such that it could not be typed in - only arrows remained operational.  However, I'm not sure how.

    James

    Hi James,

    You can use the two buttons (by releasing latch) and a digital display that shows the current value. Button increased the value and the other decreases. Store the value in a shiftregister to work with her.

    I don't know if your solution would work because use may directly enter the new value.

    It will be useful.

  • How to dynamically add any control (digital button, boolean) to control the line and selected column

    Hello

    How to add a control (digital button, boolean) dynamically in control instead of lines and columns selected. Please suggest the idea or no matter what example code you have please share with me...

    Thank you

    Vieu

    Essentially, that's what you're looking for:

    Please note that you have to account border sizes and the label of the control so that the code does not work right out of the box. You should also check for the height and width of column and if the position is valid at all before moving around the control.

  • How to create table of the method

    Hello-

    Could someone please tell me how can I create an af:table with more than one column of an AppsModule method.

    When I have a 1 d table return for example:

    public String [] createTable()}
    String [] str = new String [1];
    return str;
    }

    I can get as a table and a column is created. But how do I get mutiple columns in a table. I want to write a method that when inserted on jsp page create table with multiple columns.

    I use ADF 11 g.

    Please suggest.

    Greetings-
    Rohit

    Hello

    to do this, you use a matrix, or a list of arrays of objects. The object represents the contents of the line, e.g., person. The Person class then have setter/getter for each property you want to display in a column

  • How to create table of 288 HP push button in the PXI-6509 (3pcs)

    Hi all

    Need help...

    I am a beginner in labview. & her first time use OR for my project.

    We must push buttom about 288 HP control panel. We use PXI-6509 (3 pcs)

    & I do a code (in tie).

    but some time appear as a bug if we push a button push button after all. but some time is ok.

    Please correct the code.

    Thank you very much...

    It seems to work fine for me.  What do you mean by "sometimes appear like a bug?  How is it not behave like you want.

    A few recommendations:

    1. There is no logical reason for the node feedback on some of your cables of the error.

    2. you can turn some of your groups of buttons in a cluster.  This way you can work on changing the value of a cluster and do not have to set up 100's of changes made to the values of the individual controls.  You'd also be abe to easily use the cluster to table to transform your cluster of Boolean Boolean rather than building tables table by manually cabling up to 100's of controls.

  • How to create table selectable line or not based on the value of the line

    Hello.

    JDeveloper 11.1.1.2

    Is it possible to make a selectable table row or not based on a value in the line.

    That is to say. lets say that the row contains a Boolean LOCKED = TRUE.
    This line should not be selectable.

    A line whose value LOCKED = FALSE should be selectable.

    / Erik

    Erik,

    No particular reason to disable a selection of lines for a particular line? If I'm an end user, I would be clicking on the same line of thought again and again my mouse does not ;) (call me dumb :)). How do you differentiate this line (using inlineStyle / styleClass) based on the value of line? In addition, you can disable the other buttons when a row with a particular value is selected (so that the user knows that the selected line is not treatable).

    You must create the view as

      CREATE OR REPLACE VIEW 
  AS

     ...etc...

    The Act of creating the view will not otherwise the data in the table underlying, all it will do is create a view definition.
    Select only the view will select data.

    If you don't need to select the BLOB column in the view, then you would not include it in the list of the columns in the view definition.
    If your LOB data are stored online, then it may be a significant selection of the view, even if the BLOB column is not indicated in the list of the columns in the view.
