Flex :: Display Grid Lines In A List?

May 27, 2011

I am using a spark list control to display certain items with my custom Item Renderer. I am trying to achieve the following: (1) show a separating line between rows in my list control (2) even when not a single row has been added, I want a horizontal grid lines to be displayed in the background

I am not sure whether (1) and (2) can be achieved in one go. I can solve (1) by modifying my item renderer to have a border, I guess. But I want to know whether there is a better or more conventional way.

Flex :: Display List ItemRenderer Index?

Aug 2, 2011

Is there a direct way to get the item index of the data inside an itemRenderer? I need to display the item number against each item. I am currently doing a workaround and won't allow reuse of my itemRenderer component.

var index:int = model.dataColl.getItemIndex(data) + 1;
itemNo = index.toString();

This is what i am using now, it works, but the concepts of component reuse and data abstraction are compromised.

I am using Flex 3.

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...

Flex :: Resize A SpriteAsset Without Adding It To The Display List?

Mar 31, 2010

I have an embedded image asset (with a scale9 grid), and I'm trying to get the bitmapdata when it's resized, but I can't seem to do this without adding it to the display list.

I try this:

spriteAsset.setActualSize(w,h);
spriteAsset.width = w;
bmd.draw(spriteAsset);

But when I then draw out the bitmapdata with graphics.beginBitmapFill(), I just get the original un-stretched image.

Or do I need to take 9 separate BitmapData images and make 9 separate bitmap fills?

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 :: Display A Message That A Spark List Is Empty

Jul 13, 2011

how in Flex can I display a message within a Spark List component that states that the List is empty. For example if I have a List showing number of jobs outstanding, if my List is empty then I want a message displayed across the List stating "there are no jobs to perform".

I'd rather not use an Item Renderer because then it's an Item (the list is not empty) and the item can be selected.

Flex - Display An ArrayCollection Of Sprites In A List Component?

May 22, 2009

I have an arrayCollection of objects that extend Sprite, and have bitmaps within them. I want to display these in a list (or some other component that would allow a user to scroll through them, and see their associated data.)

When I do: myList.dataProvider = myArrayCollection

the list just shows a bunch of lines of [Object, Item] instead of the visual sprites.

Here is a simplified version of my Object:

public class myUIC extends UIComponent

[Code]...

Tried many different ways to get it to show up in a List, but can't do it.

Flex :: Horizontal Tile List To Display Image Gallery

Dec 5, 2009

I am using a horizontal tilelist in flex to display an image gallery with only one item in horiz. tilelist being shown at a time. I have next and previous buttons on both sides. The problem is I want to display a particular item/image in that list when user clicks on a thumb image from another thumbimages tilelist at bottom. I used someTilelist.selectedIndex property but it just selects that particular index in list, it does not show that particular item/image. I want the list to show that particular image, not just select it. Please take note that the horiz. tilelist shows only one image at time.

Flex :: Resize Nested Mx:Lists To Display All List Items?

Aug 17, 2010

I'm trying to create a nested list in Flex which will dynamically resize to display all children when the data provider changes.

Here's a simplified example which illustrates the problem:

<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;

[Code].....

The list sizes remain static when items are added.

If I add variableRowHeight="true" to the outer list then the inner lists will correctly resize. But the outer list itself remains at a fixed size.

How can I have both lists resize automatically to display all children?

I need to make a flash game which has almost 1K 50x50 bitmaps moving on screen(more than 10K display object in display list), and want to know if flash can support it well on a normal PC with at least 30FPS.

ActionScript 3.0 :: Dynamically Add Component - Flex Did Not Reserve Space For List To Display

Jul 21, 2009

Here is part of my code in short:

[Code]....

I realized that if I do addChild, I can't really see the dynamically added component, since flex did not reserve space for my List to display. So I do parentDocument.addChild, and then it appears no problem. My question is since it's being added in the parentDocument, so it is suppose to be a component belong to parentDocument, so is that component still be able to call this handleMouseDown? From my experience, it's still able to, but which doesn't make sense to me. Can someone explain a little about why it can still work, or any better approach other than parentDocument.addChild

Flash - Sorting Display Objects By Their Display List Depth

Aug 5, 2011

I have a list containing display objects from throughout the application (insertion order). I want to process the list either top-down (parent, child) or bottom up (child, parent). The only requirement is that either a parent is processed before any child or vice versa a child before its parent. What is a good approach? This question is not about sorting a list. It's about retrieving the depth of a particular display object.

Example
Display list:
A (root)
B1
C1
C2
D1
B2
......

My list:
list = [E1, F4, A, B2, B1, C3, ..., N9, N8]

Bottom-up:
N9, N8, F4, E1, C3, B2, B1, A

Top-down:
A, B2, B1, C3, E1, F4, N9, N8
Does not matter if N9 before N8 or N8 before N9. Important is that any N is before M (first run) or any M before its children N* (second run).

Flex :: 3: Scrolling Of List Items With In A List Via Scroll Wheel

Dec 31, 2009

Here is a snip from within my code:

[Code]...

The 'recommendations' dataProvider is an ArrayCollection of String, which are generally sentences about as long as this one. By setting the variableRowHeight and wordWrap properties as shown, if a sentence is too long to fit on a single line, everything works fine- the row expands and the messages show on two lines, or occasionally three.

The space allocated for this panel within the entire canvas means if the total text size of 'recommendations' exceeds six lines, I need for the entire list scroll. This is also working just fine. The trouble is when using the mouse wheel to do the scrolling- Flex scrolls both the entire list and the single item where the mouse is hovering. Often this results in only the second half of a sentence being visible. Non-programmer friends I have asked to look at this noticed this, and tell me it as a problem. If a user does not notice the dual scrolling, and sees only a fragment of a sentence, it will be perceived as an error in the application.
