Flex :: Flash - Custom List Selection Not Highlighting?

Mar 18, 2010

I want to create a custom list in Flex for an interface prototype. The list is supposed to have an image and 3 text fields. This is what I have done so far, the control displayed is what I want. But, when I click on one of the items, the item does not appear (visually) to be selected. I was not sure how I would implement this.

Here is my code so far:

<s:List width="400" height="220"
dataProvider="{arrColl}"
alternatingItemColors="[#EEEEEE, white]">
<s:itemRenderer>

[Code].....

Flex :: DataGrid List Is Highlighting

Jan 10, 2011

By default, whenever you rollOver/mouseOver (not sure of the difference) an item in a Datagrid or a List, that item is highlighted with the component's rollOverColor.I'm just wondering if there's any way to do that programmatically. I haven't been able to find much help on the issue. For example,suppose I have two DataGrids.When I rollOver an item in the first DataGrid, I want to highlight the corresponding index in the second one as well.Basically, as if two separate cursors were rollOver'ing two separate DataGrids.

Flex :: Spark List Not Displaying Selection When An Item Is Removed

Aug 3, 2011

I have an issue with Spark Lists whereby I am trying to ensure that an item is always selected and ensure that the GUI displays this to the user.

The application (full code below) creates a List, a Label and a Button. The Label states what is selected in the List. The button removes the selected item. Changing the selection, updates the text in the Label. Important: The List has "requireSelection" set to true to ensure that an item is always selected.

If I select the first item in the List, the selection is correctly reflected in the label. Clicking "Remove" removes the item and the next item is selected. This is all working correctly.[code]...

Flex :: Find Out Deselected Item In Spark List With Multiple Selection

Aug 3, 2010

In 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?

Flex :: Unable To Select Item In Spark.components.List After De-selection

Dec 21, 2010

I have a spark List defined as:

<s:List id="symbolList" dataProvider="{symbolListCollection}" change="symbolNameChangeHandler(event)"></s:List>

With the change handler defined like this:

protected function symbolNameChangeHandler(event:IndexChangeEvent):void {
symbolList.validateProperties();
changeSymbolView(symbolList.selectedItem);
}

and symbolListCollection as an ArrayList filled with Strings.

At first, the change event works fine, and I get what I expect.

However, if I Ctrl-click on the selected item, to de-select it, i am unable to ever select an item again.

When I click on something to try to select it, the change event DOES fire, however, the ItemChangeEvent has both oldIndex and newIndex set to -1

Flex :: Get List Item Selection Working When Using A Png Mask In An Item Renderer In A 4.5 Mobile App?

Jun 10, 2011

I'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;

Flex :: Creating A Custom List Component

Jan 10, 2011

I'm trying to extend the mx:Box container so that two buttons sit on the outside of the container to cycle through it's contents (similar to a scrollbar).

I've made a custom component that looks basically
like "mx:HBox->mx:Button mx:Box mx:Button" where the buttons and box are children of the hbox.

How do I offer the user access to the box (say its dataProvider and itemRenderer) through my custom component?

So they just need to write 'local:MyCustomComponent dataProvider="rar" itemRenderer="rar"/>' and my box inside that component can use it?

Flex :: How To Add Spark List Item Custom Properties

Jan 3, 2011

I'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).

Flex :: Custom Component Not Updating Display List?

Jul 12, 2011

I've created a component which is basically a meter (extends skinnable container). The skin to the component contains two rectangles (background and the actual meter). This component receives an arraycollection with the following fields value, max and min(the arraycollection I am passing is Bindable). When I initialize and pass the data to be used to draw It works great (keep in mind - only works the first time). I've created a button that changes the data array and shows the current meter value. Apparently the meter's value is changing everytime I modify the ArrayCollection I've set to be used for rendering.(dont want to say "dataProvider" because it is not a Flex dataprovider, just a variable )... here is the code...

public class meter extends SkinnableContainer {
[SkinPart( required = "true" )]
public var meter:spark.primitives.Rect;

Flex :: 4.5 : Strange Scrolling Behaviour In Custom Layout Used In A List

Sep 15, 2011

I created a custom layout for a list, to be used on a mobile (android). I used this as example : [URL], using virtualization. Now the problem I have is with scrolling : when scrolling to the bottom of the list, there seems to be always a "bounce back", as if the list would have reached and as if the bounce/pull effect is taking place. But in fact the list has not reached the end at all, in fact I can not even scroll to the last element in the list. When going back from bottom to top, there's no problem at all.

I trace the top and bottom of the Scrolling Rectangle (Rectangle.getScrollRect) and there I can see that when scrolling down, the top and bottom parameters increase, but when releasing the touchscreen, all of a sudden the parameters decrease again with a certain amount, and so never reaching the end of the list. All my code is available on google project hosting : [URL]
