Flex :: VGroup: How To Have A New Element Show Up Smoothly (resize) When Added/removed

Apr 20, 2011

When adding/removing elements to/from a VGroup I need it to happen smoothly, resize the item. I believe I have to use transition effects. But how?

At item (element) level? At VGroup level? Should I use a DataGroup instead and do it at ItemRenderer level?

I've been trying to do it at item level but I still didn't manage to make it work and somehow it doesn't feel right. It feels like it should be done at a higher level.

For example, I defined a "death" state which resizes the item to height=0. But then, after it shrunk, it has to somehow notify VGroup in order for it to be removed or remove itself from VGroup. It feels unnecessarily complicated.

way to associate an effect to inserting and removing items from a VGroup?

Flex :: Float - 4: While In A Vgroup - Add A Moveable Element That Won't Be Part Of The Vgroup?

Jun 22, 2010

I created several components that are placed inside a VGroup. in one of the components code, i want to add an image and to move it. i don't want the image to be part of the vgroup and to be bound to the vgroup area, i want it to be like float in css. how can I do that?

update I want to be able to move the element in the entire area of the application. not to move it within the vgroup. i don't want this object to be attached to any container besides the main application window in order for me not to have limits how much can i move it and where.

Actionscript 3 :: Button Removed With RemoveChild() Gets Re-added In It's Over State?

Sep 5, 2011

I have a SimpleButton on the stage, and in the click event for it, I remove it using removeChild(). When re-adding the button, it gets re-added in it's "over" state, not the "up" state as expected.

I'm pretty sure it's a bug, so I've filed a JIRA:[URL]..What I've tried: sing visible = false instead works, but I'd prefer to remove it off the stage altogether as the game I'm working on can have a lot of popups/screens. Firing the mouse_out event manually - doesn't work, and in any case, the mouse_out event fires as expected (perhaps before resetting to the up state, it makes a check to see if it's added to the stage, finds out it's not, then quits early)Resetting the stage focus - I thought it was a problem with the stage focus, as you were losing focus when the button was hidden, but resetting it didn't fix it.I could temporarily swap the over and up state when it's hidden, but that seems like an ugly fix.

Flex :: Why Doesn't ListCollectionView Show New Items Added To The Underlying List

Jun 20, 2011

I have an (empty) ArrayCollection that I wrap with a ListCollectionView. Then I add a series of items to the ArrayCollection, but these are not showing up in the view.

public var transactions : ArrayCollection = new ArrayCollection();
public var filteredTransactions : ListCollectionView = new ListCollectionView(transactions);

transactions contains 150 items, filteredTransactions contains none. I originally thought it was the filter I was applying, but even when I remove the filter, I still get no items in the filtered list.

Do I need to add the items to the view as well as the underlying collection (this would seem to defeat the purpose of using a view though...)?

ActionScript 2.0 :: Check An Array To See If An Element Has Already Been Added?

Feb 4, 2005

is there a way to check an array to see if an element has already been added? I'm working with an XML document where there are 4 possible variables, but these 4 vars are repeated several times over. It's reading in fine... I just want to pull those specific variables out of the XML and add them to an array, but I do not want them to duplicate. To say it another way... I don't want my array to be more than 4 items long (it is possible to be less) with a max of those 4 different vars.

Actionscript 3 :: FLEX 4.0 Vgroup Seems Not To Draw Their Elements?

Jan 23, 2012

I got a component made with an spark Group for a survey, inside of it I have an algorithm that create the questions putting RadioButtons inside of a VGroup(dynamically).The problem is that sometimes when I call the next question, I couldn't find why, they are not drawn unless I click the right mouse button so it appears normally.

public function nextQuestion(event:MouseEvent):void
{
destroyQuestion();[code].....

So, when I run the application and I move through the questions, sometimes, the question is not drawn (exemple: I'm at question 2 and I move to the third question and it's blank, but if i press the right button in my mouse the question suddenly appears. So I move to the fourth and everything seems right)

Flex :: Change S:VGroup Height When Child.visible Set To False

Nov 12, 2010

I have a code similar to this:

<s:VGroup>
<s:HGroup verticalAlign="middle">
<s:Label text="label" />
<s:TextInput id="rmName"/>

[Code].....

I want that the s:VGroup container has the height only of its visible children. In this example there is a free space even the visibility mx:HorizontalList is set to false. Every time I change the visibility of the child element I want that the parent (s:VGroup) will change his height. How to do this in flex?

Flex :: VGroup - (Parent) Container Does Not Change Height With Children?

May 13, 2011

I have code like the following:
<s:VGroup gap="10" id="group" height="100%">
<s:Label text="This is page 2" />
<s:Button content="Resize Canvas" click="resize(event);"/>
<mx:Canvas id="photoCanvas" color="#567898" backgroundColor="#125567">
</mx:Canvas>
</s:VGroup>

I don't understand why the following does not work:
Pushing the Button resizes the photoCanvas's height (gets taller or smaller). Since the photoCanvas control is a child element of the VGroup shouldn't the container update itself to the new height? The Vgroup has ALWAYS the same height, no matter what the (total) height of the children is! I would like the VGroup to adjust itself and get a height value equal to the sum of its children heights. Is this not possible??

ActionScript 3.0 :: Stage Element Positions On Resize?

I have created the menu buttons and band but I can't figure out how to maintain their relationship with the edges of the browser window if it is rezised at any point during a user's visit (same as the site above).

I have been setting the position of the buttons and all other elements using, for example :

myBtn.y = stage.stageHeight - 100;myBtn.x = stage.stageWidth - stage.stageWidth + 50;
 
For publishing I use noscale, 100x100 percent, top-left justification.

ActionScript 3.0 :: Prevent Parent Resize When Children Is Added?

Dec 23, 2009

I have a rectangular movieClip named 'container'. In this movieclip, a function generates some number of squares.My problem is that; for example, if I generate 12x12 squares with each width/height of 40; it resizes the container to width/height of 480. If I set the width and the height of the container movieClip to a lower value; then the squares become smaller.I have been struggling for some time on this problem. I tried setting the ScaleMode of container and squares to various values but it did not work.How can I overcome this illogical (for me at least) problem? How can I prevent children from resizing their parent OR how can i prevent parent downsizing the children?

ActionScript 3.0 :: Object Does Not Show On Screen Once Re-added To Display List?

Nov 3, 2011

I have an object that is instantiated, then placed into a property within a singleton (single instance) object. When a button is clicked an event is dispatched carrying a payload that references the display object that is held within the Singleton. When the event is heard, my view object adds the object to the display list e.g. addChild().The Item shows. Now If I hit another button an event is dispatched, and a new item is added to the display list via the method above and is seen. The 1st object is removed from the display list Here is my problem. When I click the button to load the 1st Object the above process is executed again but the object does not show.

I can run trace statements from the object that is supposed to be visible and they run fine. I even do a check to see if the visible property is set to true, and it is, but not object is on my screen. Code for this process.

//custom event carries the name of the page aka display object. this is a string
dispatchEvent(new MenuEvent(MenuEvent.CHANGE_VIEW_STATE, event.payload));
//When the event is heard, the following condinial is run

ActionScript 3.0 :: Call The Slide Show Swf That Must Be Added ABOVE The Main Swf In The Display

Feb 21, 2011

The site operates around a swf named main.swf. All the different content areas are external swfs called by a navbar in main.swf. One of the primary content areas is a gallery of our work, with five separate types; branding, package design, collateral, Internet, and Digital. The left hand swf for the Gallery section contains five movie clips that let you select the specific gallery area that displays on the right hand side. Included in the right hand area are thumbnails (movie clips) that when clicked she wants a Greybox-like slide show to appear over the entire area (1100x x 690), INCLUDING the main.swf. As I currently envision it, this is an 1100 x 690 XML-driven portfolio swf, with the alpha of the overall stage box at about 30%, and the actual gallery centered.

If I haven't lost you, my challenge is to call the slide show swf from a click event in the thumbnail on the right hand side. If I understand the Display Object Model this swf is about three levels removed from the stage.

How do I call the slide show swf that must be added ABOVE the main swf in the Display List from a click on the right hand area thumbnail?

I'm gaining a better understanding of classes, and am using them to hold all the AS for the external swfs. Basically I need to be able to talk to the main swf from the brandRight.swf which is the right hand swf containing the thumbnails.

Actionscript 3 :: Dynamically Added FormItem Doesn't Show Error Text

Mar 29, 2012

I am dynamically creating a form on runtime of my application. The content of my form item (lets call it MyFormItemContent) looks like this (simplified):

<?xml version="1.0" encoding="utf-8"?>
<s:BorderContainer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
width="100%" borderAlpha="0.0">

[code]...

If the validation of MyValidator has errors a red frame apears around the BorderContainer as intended. But unfortunatly the error text that should apear right to the form item doesn't. I'm thinkin it's a layout problem because I define the validator inside the form item content before adding it to the form. I've already debugged this and read documentations a lot.

Javascript :: Algorithm Does An HTML SELECT Element Uses To Show Results As Type?

Jan 21, 2010

In most browsers, when you have one in focus and you type something, the combobox will try to find the value within its options and show the closest one. I was wondering what kind of algorithm is used for that.I don't think its Levenshtein or similar since it only works with the beginning of the string.I'm thinking that it works by keeping a buffer of what has been written, and tries to find a string starting with that... if it doesn't find anything, it clears the buffer, and searches a string beginning with the last character pressed.I already prototyped this, and it works quite ok, with one caveat... In HTML, when you repeatedly press the same key, it will rotate between all options starting with that character.

Flex :: Actionscript 3 - Making A DataGrid Scroll Smoothly?

Dec 2, 2009

I've noticed that the default behaviour for a DataGrid's vertical scroll bar is to scroll one row at a time. This is all well and good when the rows are all uniform and small (e.g. displaying a single line of text), but gets really ugly as soon as you have rows with variable heights.I'm curious, is there a way to make DataGrid scrolling "smooth"? For instance, is there a way to have the DataGrid scroll by a set number of pixels, lines of text, etc. rather than scrolling one row at a time?

So far, the only solution I've managed to come up with is to place the DataGrid in a Canvas and have the Canvas do the scrolling instead of the DataGrid. The issue with this approach, though, is that as soon as the Canvas scrolls far enough, the DataGrid headers scroll off-screen. Ideally, I'd like to get the smooth-scrolling nature of the Canvas, but also keep the DataGrid headers visible.
