Flash :: Delete XMLList Data After Certain Element?

Nov 3, 2010

Basically, since XMLList are similar to Arrays in many ways, I was wondering if I could do something like:

XMLList.length = 10;

I know this is not possible because 'length' in XMLList is not a property but is a method. Hence is something like a get method without a set method. Only XMLList.length() would work.

Flex :: Get The Index Of First Visible Element?

Jan 21, 2011

I have a simple list in Flex that is populated every N seconds by a dataprovider. My goal is to avoid scrolling the list after the dataprovider has been changed.

So, before I populate the list, I save the selectedIndex, and once the dataProvider is filled, I call:

list.selectedIndex = index;
list.scrollToIndex(index);

Trouble is that this moves the selected item of the list to the top. The solution would be to get the index of the first element displayed in the list: but I have no idea on how to get that.

Flex :: Delete Item From Collection Bound To Datagrid And Update The Grid Selected Index

Feb 20, 2011

I have a datagrid with an xmlListCollection bound to it:

<mx:DataGrid id="dgCompetente" includeIn="Competente" x="10" y="66" width="547" height="468"
change="dgCompetente_changeHandler(event)" dataProvider="{colCompetente}"
editable="false">

[Code]......

I want the selectedIndex to remain the same. So, if I delete item 2, the next in the list should be selected. The problem is that if I delete item 2, item 3 will be selected and I have no idea why.

ActionScript 3.0 :: XmlList Attributes Index Order

Jan 14, 2009

My xml file that is dynamically generated and contains an attribute that may or may not exist in every node. In this case it's "title"

<album>
<img file="001" title="title1"/>
<img file="002" title="title2"/>
<img file="003"/>
<img file="004" title="sometext"/>
</album>

img file = an image that get's displayed, and I want to test when each file is displayed what the "title" attribute =. That all works great. So depending on what img file I'm using (based on index position), I'm grabbing the title attribute with the position index. The problem is when an attribute is missing the next "title" attribute is moving down into that index position. so when I look for the attribute like this.

[Code]...

Is there a way for the list to hold it's index position based on the img tag and then let me dig down via dot and attribute name? I've tried all sorts of combos with no success.

ActionScript 3.0 :: Append XMLList And Element Function

Apr 8, 2009

I have an XMLList:
Code:
var contentList:XMLList = loadedXML.someNode.elements(nodeFromNavElement);

Where "nodeFromNavElement" is a var being passed from a movie clip the user clicks on. That all works fine. The user is now in a particular section of the Flash app, and the content being pulled from the XML corresponds to the section. If the user clicks another movie clip (or navigation element, the content needs to update.

I need to get another node within the current node, like this:
Code:
var contentList:XMLList = loadedXML.someNode.elements(nodeFromNavElement).elements(nextNodeFromNavElement);

But I'm trying to append to the XMLList... something like:
Code:
var contentList:XMLList = loadedXML.someNode.elements(nodeFromNavElement) + .elements(nextNodeFromNavElement);
Which obviously doesn't (and shouldn't) work.

Actionscript :: Get Index In An Array Of A Clicked Element In It?

Aug 10, 2011

I'm trying to create a virtual keyboard.

I have a class VirtualKeyboard which contains an array called keyboard of 26 movieclips, each one representing a letter.

In the main class, I create an object of the class VirtualKeyboard and added an eventlistener on it when a letter is clicked.[code]...

But the index always returns the value 4294967295.

How can I know which letter was clicked, I mean the index in the keyboard array corresponding to that letter?

The same code is working correctly if I put it in the VirtualKeyboard class, but not from the main class.

ActionScript 3.0 :: Array Index - Cannot Loop Through Every Element

May 31, 2010

I search the stage for the level I created and put the floor pieces into an array. I'm trying to test the properties I created for each piece by tracing to output when the hero sprite is within the floor pieces sides. This works fine when I specify the array index to do this for, but does not work when I try to loop through every element of the array. I see no reason why this code should not work.

package {
import flash.display.*;
import flash.events.*;
import flash.utils.getTimer;
import flash.utils.Timer;
public class MegaManTest extends MovieClip {
private var hero:Object;

Actionscript 3 :: Determine The Index Of An Element In Array That Has Been Clicked?

Jan 3, 2012

Say, I have an array of movie clips (dummies). Each dummy has an event listener and reacts to clicks. And when a dummy is clicked, I want to know the index of the clicked dummy.

I've only come up with this solution: run through the whole array of dummies and find out which dummy is the target, then exit the 'for' cycle and assign some global variable the value of counter variable, but this way the application I am building will demontsrate poor performance.

Flex :: Combobox Backspace Or Delete Key Does Not Delete Highlighted Text

Mar 26, 2010

I am implementing a flex auto-suggest combobox - as the user types in each character: Consider the string 'Stackoverflow' and user input = 'st'

1) the data provider is filtered to show all items starting with 'st'
2) text is set to auto-suggest string such that the un-typed part is highlighted.

So for instance, the combobox text may contain st'ackoverflow', where 'ackoverflow' is highlighted using setSelectedIndex()When I hit back-space or delete, and check the 'this.text' value, I expect that the last un-highlighted character ('t' in the above case) gets deleted and the data provider is filtered to show all items starting with 's'. However the text property contains 'st', as before

Flex :: Loop Through XMLList?

Feb 24, 2011

I'm trying to loop through an XMLList and rather than giving me each item in the list as XML, it's just coming back with the positions as strings e.g.

[Code]...

It just alerts "0" or "1". If I inspect the 'item' variable, I see the same thing. But if I inspect 'myList' it looks like the XML. I've also tried myList.children() and strongly typing 'items' to 'XML' but nothing I do has worked.

What it says on the tin: I have an XMLList, and I want to find where in it a particular XML item falls. First index is good enough for my purposes. Note that I have no problem writing a function to do this by hand... but I was hoping that the API has something buried somewhere that'll do it for me. I didn't see it, though.

Xml :: Flex - Display A List Of Items In A Datagrid From A XMLList?

Oct 19, 2009

I am trying to display a list of items in a datagrid from a XMLList.

<Series no="1">
<file>
<filenum>1</epnum>
<prodnum>4V01</prodnum>

[code]...

My current code allows me to retrieve every Series into an XMLList and then i have a nesteddatagrid class that allows me to do things like.

<classes:NestedDataGrid width="100%" height="100%" id="gridFiles" dataProvider="{filesList}" >
<classes:columns>
<mx:DataGridColumn headerText="Season" dataField="@no" width="60"/>

[code]...

However this displays the datagrid with two rows, the first row has 1 in the Series column and then the two files crammed into the second cell in the same row. The second row is the same but has the number 2 in the Series column and the two series #2 files crammed into the cell next to it.If i do not use the nested data class i can pull the files using Series.file instead and all 4 of the files list correctly, however i do not get the Series number for each...
