Flex 3 :: Refreshing Repeater After Adding A Child
May 23, 2011
Within a child, I have an XML element with the following structure:[code]I then use a repeater to list each out onto the screen. There's a button I have created that is used to create a position. So, once the user clicks this button, I call the following function:[code]The above function creates a new XML object, puts some default values in, and appends it to the list of project positions. After appending the new information, I made the height of the project larger and then check to make sure the new project height isn't overlapping any other projects... but that information is irrelevant to this post.My problem is this - once i append a new child to the XML variable, it doesn't appear on the screen. Is there a "refresh" or "re-render" option i can do to the repeater in order to make the new child show?[code]Once i make the changes, and use the XMLListCollection as the dataprovider in the repeater, the information no longer loads on the screen.
I have a problem when creating a ViewStack, with a repeater along with other components (i.e. vBox) inside the ViewStack. The repeaters get placed at the bottom of the view. Despite the repeater is listed before other components, it is placed at the bottom.Is there a workaround where I can get the repeater drawn before the other components?Here is an example:
I have a repeater component with custom event. My repeater components fires custom event holding data. My need is to dispatch event so other repeater components can access data from dispatching component.
I have a custom component in a repeater. This component has a child component which can be of two types depending on some conditions. [coed]...
When I place breakpoints in the functions called at creationComplete, I can see that the component assigned to placeHolder is correct but it does not show on my display. I tried refreshing by calling invalidateDisplayList in every place I can think of but it does not seem to work.
I'm having a problem when adding a child to a VBox component. Is it not the same thing?:
List Item:
<mx:Script> <![CDATA[ public function addChildren():void {
[Code]....
I am injecting two properties (question and answer) to the FaqItem component from an auxiliar file (using BabelFX) that depends on the id of the FaqItem, but it is only working when I choose the second option. If I use the first option, I get a child but with the text in question and answer fields is empty. I need to use the first option.
How can I add an MXML component as a child of the main application using ActionScript. It's not possible to instatiate it, is it? Assuming that behind every mxml file stands an actionscrpt3 class, I tried to import it but id didn't show up.
I have a panel with a button in it. Clicking on the button will direct the panel to state "State2" adding another two buttons into the panel. During the state change, I want the panel to resize first and then show the newly added two buttons, so I applied transitions onto the state change.
My question is:
If I put the two buttons within a HBox directly under the addChild tag, it works fine. However, if I create a new component with the same code (HBox with two buttons in it) and then add the new component to the panel (Comp in the code commented), it won't show the resize effect.
I've a custom component where I do some graphics (e.g draw a line) and dynamically add a subcomponent (e.g a label) to it.
If I base the component off Group (which is recommended as per docs since its a spark component) then when I dynamically add a label the graphics part disappears.
However if I base it off Canvas this doesn't happen.
Why is that the case?
Here is the code.
MyComponent.as public class MyComponent extends Group { public var x1:int;
I've seen some discussion on how to load a child swf using swfLoader and accessing it's variables but I am wondering if it is possible to do this without adding any code to the child swf.Either accessing public vars or listening for funciton calls would work fine
In my application I'm using a canvas and repeater inside HBox it is Dynamic,..now I want to keep a horizontal scrollbar for the same, I may display more than 50 canvas addresses inside that Hbox and repeater.Here is my code:
I have a label that is using a repeater to get information form a database. Now I'm trying to pass the information in that label to another label component, but I haven't had any luck.[code]...
I Have a VBox, and set the verticleGap = 0. Inside the VBox I have a Repeater. When I run the App, the items listed from the Repeater have a large gap between each line. Is there a way to set the verticleGap on the Repeater, or reduce that space?
I have an xml file that has a start date and length of a project... I use a repeater to load each project. The users' screen only shows 2 weeks at a time. I would like to make it so that if a project doesn't fall within the two weeks on screen, that the project isn't loaded. I could do this by sorting through the XML and finding the correct projects to load, and putting them into an array collection, but there's a "move date" button which allows the user to change the two weeks that are showed. Once the two weeks are changed, I would need the projects that fit into that new 2 week window to show.
I have a randomly-sized array of items. I'd like to display one label for each item in a Repeater component. I want them to display in a grid layout with 5 columns and as many rows as needed. How do I do that in Flex / ActionScript?
i have the following code: <mx:Repeater id="user" dataProvider="{data}"> <mx:VBox styleName="repeaterVBox"> <mx:Text text="{user.currentItem.a}. {user.currentItem.b}"
[Code]....
the dataProvider 'data' updated itself every 3 seconds, so every 3 seconds that is a flicker of some sort, i see for a really short time an empty area and then it gets redrawn again. is there a way to make the update somewhat faster ?
I trying to import an XML file, and send bits and pieces to a custom component. My XML file is structured like this:
<projects><project> <projName>{Insert title of project here}</projName> <startDate>{Insert date here}</startDate> <positions> <daysOffset>{Insert a number here}</daysOffset> [Code] .....
When I save the project, I do not get any errors or warnings. However, when I attempt to output the values in the component, the projectPositions piece comes back as Null.
I have a flex repeater for an accordion inside a TitleWindow that is quite slow, I've already set recycleChildren to true, which has helped, but it's still slow on the first load and causes the animation to stutter when I open the TitleWindow.
The repeater is just one part of what's visible in the TitleWindow, what I would like to do is have the repeater load after the rest of the content in the TitleWindow so the animation of the TitleWindow being opened doesn't stutter (the main problem).
I have an mxml panel in which I'm using a repeater. The panel can be resized horizontally and I would like for the repeated components to resize together with panel. Here is a simplified example of how things look like:
<mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" ...> <!-- scripts and some controls --> <mx:VBox width="100%">
When code changes for allItems the item disapears from screen as expected but still sits in memory! I know this by a function inside a compoenent that has "trace" so the trace output still displays even after the component disappears from screen. How do I ensure that the element is deleted when it's reference is deleted? Will using List-based component to display items instead of "Repeator" solve the problem (it requires significant refactoring of my code so I'm asking before trying it out)
I have a label inside a repeater (rptInfos), and I have an arraycollection (Texts) that has the translations. The "Texts" content is changing when I change the language, and normally I use {Texts.getItemAt(219}} for example when I need a translated text. But in the repeater I have a translateable column, so I want to use it like this:
<s:Label text="{Texts.getItemAt(rptInfos.currentItem.DictID as int)}" />
but it says "Syntax error: expected a definition keyword (such as function) after attribute , not target".I wanted to translate it in the labels creationComplete event, but than I can forget about binding, so only when reloaded can I have the content to update.
Following error is arising if I use NavigatorContent in Repeater. Is there a way to initialize image and lable on which I am encountering following error: Unable to generate initialization codewithin Repeater, due to id or databinding on a component that is not a visual child.
This doesn't work. creationComplete is not called until the repeater has finished instead of (as I expected) when the creation of the button is complete. I'm not sure how to accomplish this.
BTW - I also tried placing the creationComplete on the parent component to the repeater, but it would only be called the first time the component was rendered (the data inside the repeater sometimes changes) so that didn't work.
I have a flex application that has a home button. I need to reset the application when this button is clicked. I can't use navigateToURL or ExternalInterface.call("window.location.reload"); as its not acceptable to reload the swf file.
