Flex :: Handling Mouse Click 4 List To Find The Selected Item (since ItemClick Is Gone)?
Dec 8, 2011I have prepared a simplified test case for my question. It will run instantly in your Flash Builder if you put the 2 files below into a project.I'm trying to display a List of strings and a confirmation checkbox in a popup:In the real application I dispatch a custom event with the string selected in the list, but in the test code below I just call trace(str);My problem: if I use click event, then the window closes, even if I click at a scrollbar (the !str check below doesn'twhen an item had been selected in previous use). And if I use change event, then the window doesn't close, when I click on the same item as the last time.riting a custom item renderer and having a click event handler for each item seems to be overkill for this case, because I have strings in the list.Test.mxml: (please click myBtn few times - to see my problems with click and change)

Flex :: Find Out Deselected Item In Spark List With Multiple Selection
Aug 3, 2010In a spark list I could use the change event to find out which item has been selected or deselected. The dispatched IndexChangeEvent object has the properties newIndex and oldIndex holding this information.
But with multiple selection allowed this doesn't work anymore because newIndex and oldIndex could refer to indices of still selected elements.
A solution would be to copy the selectedIndices vector to another variable and compare this variable with selectedIndices after a change in selection, but this seems to be somewhat complex.
Does anyone know if there is an easy way two get the index/item a user is deselecting while other elements are still selected?
Custom Mouse Pointer - Get To Act As The Mouse Pointer For The Whole Page
May 4, 2009I've read some previous post by others, and have got the concept of how to make it happen just need to ask a few specific questions, one is the action script for changing the movie to the cursor and telling it how to move as the mouse cursor, next question is how do i get to act as the mouse pointer for the whole page, for instance I'm using frames I've got my buttons in the left frame, with a banner it the nested top and then the pages of course load in the main frame, how when creating the mouse cursor do i get it to work all over the page? I wasn't sure if using the normal method if it acts through out the whole site or just over a flash movie.
View 3 RepliesFlex :: Get List Item Selection Working When Using A Png Mask In An Item Renderer In A 4.5 Mobile App?
Jun 10, 2011I'm creating a mobile app in which I need to show a calendar with months at the top. The months are part of a component that extends from SkinnableDataContainer (and has some custom scrolling/behaviour - which is why I did'nt use a spark list). I need the months to be shown as a 'trapezium' shaped tab and so I'm using a png image as a mask in the item renderer for the component.
When the mask is not applied, it all works well - the months render, the list/data container selection works when I click on a month and so on.When the mask is applied, it renders well, scrolling and everything else seems to work well - but when I click on a month, nothing happens visually. And from the trace statements in my code, it appears list item selection is not changing. Looks like mouse clicks are not working.
Code:
public class TopCalendarMonthRenderer extends LabelItemRenderer {
[Embed(source="/assets/trapezium_alpha.png")]
private static var TrapeziumMask:Class;
private static var trapeziumMaskInstance:BitmapAsset;

Flash :: List Component - Change Pointer Icon To Hand For List Items?
Nov 9, 2010I am working on an older Flash project created in CS3 ActionScript 2.0 How can I make the pointer cursor change to the hand when hover over a list item?_root.slidePanel.myList'myList' is the list. I have traced out the contents of the List MC and it has a child MC called 'content_mc'.

Flex :: Caching Images In List Item Renderer?

View 3 RepliesFlex :: How To Set Variable Size For List Control Item
Jun 17, 2010The following code display a list of comments using List control. The item height set to a fixed value (150), so it seems working: if the content is too long, the scrollbar shows. However, what I really want is not to set the height but let it to change according to the content size. Is there any way to accomplish this?
<mx:List id="commentList" width="100%" dataProvider="{commentSet.commentArrayColl}" rowCount="{commentSet.commentArrayColl.length}" >
<mx:itemRenderer> <mx:Component>
<mx:VBox width="100%" height="150" >
<mx:Text text="{data.commentContent}" />
<mx:Text text="{data.username} ({data.modified})"/>
</mx:VBox> </mx:Component>
</mx:itemRenderer> </mx:List>
To be more clear, I don't want to set the itemRenderer's VBox height to "150" or any other fixed value - but it'll only show one line of the text if I don't do it. So I'm looking for a way out of this. (If the VBox is not inside the itemRenderer, it'll auto adjust height as Text field string length grows - that's what I want.)

View 1 RepliesFlex :: Select & Deselect Same Item In <s:List> With A Mousedown?
Dec 14, 2010In Flex 4, I have a Spark List component with item renderers. I would like to select an item in the List by clicking on it, and deselect it also, by clicking on the same selected item. Like an on/off switch.
My item renderer has the following states:
<s:states>
<s:State name="normal"/>
<s:State name="hovered"/>
<s:State name="selected"/>
</s:states>
so I tried to add a click event listener to the item renderer with:
private function selectUnSelect():void {
if (currentState == 'selected') currentState = 'normal';
else currentState = 'selected';
}
with an awkward behaviour... where the item stay selected even after clicking it again in the selected state.
Think of using the List component without the Command (on mac) or the Control button on windows.
Flex :: How To Add Spark List Item Custom Properties
Jan 3, 2011I'm trying to make a simple flash application providing interface for taking tests as a high school assignment. One of the requirements is to use an XML file as data source.Now, having a List component bound to the XML file with questions consisting of data such as question body, question type (ie. single choice, multiple choice, open, image etc.) and possible answers (where applicable), I was wondering if I could add some additional data (and what is the best possible way to do so) to each question upon its transfer to the List component.
I am trying to achieve two main goals with this: firstly, to mark the questions to which an answer has already been given, like with such code in ItemRenderer class:
<s:Label color="{data.color}" text="{data.label}"/>
Where data.color would be set whenever the user gives an answer to a question.
Secondly, while at it, I thought of such possibility as a great way to store answers given to particular questions. In this case, the Class of the answer object would have been Object, since there has to be many type of questions (where the answer could also be a Bitmap for example).

Actionscript 3 :: Flex: Special-casing An Item In A List Or Menu?
Aug 4, 2009I've found it's often useful to special case the first item in a drop-down menu (ie, an instance of Menu). For example, if I want to pick a color from the list provided by a web service:
<mx:PopUpMenuButton id="colorSelelector"
dataProvider="{colorsService.lastResult}" />
I might also want a special-case, which is "enter a new color", allowing the user to enter the RGB values for a new color which isn't in the list. For example:
var newColor = { label: "Enter a new color", rgb: null };
Then used with:
<mx:PopUpMenuButton id="colorSelelector"
dataProvider="{colorsService.lastResult}"
lastOption="{newColor}" />
So, apart from changing the list I get back from the service, is there any better way to do this?
(and just a preemptive comment: this is a simplification... I'm not actually trying to make a color-picking-list)
