• Flex: vertical gap between list items not working

  - by pfunc

  I have a list item with buttons in it like so: <mx:List contentBackgroundAlpha="0" baseColor="0x333333" leading="10" id="weekButtonList" width="260" borderVisible="false" dataProvider="{_data.mappoints.week.@number}" itemClick="onWeekClick(event);" > <mx:itemRenderer > <mx:Component> <mx:Button buttonMode="true" width="260" height="50" label="Week {data}" /> </mx:Component> </mx:itemRenderer> </mx:List> No matter what I do, these buttons have a vertical gap inbetween them. I have tried everything from setting the "vertical-gap" property to negative and positive numbers as well as changing the padding-bottom and padding-top on them. I want the buttons to be right up against eachother vertically. I have also tried "button-height" and padding on the List component...still nothing. How do I control this?

• How do I add a combo box to a DataGrid?

  - by FigBug

  I want to add a ComboBox to a DataGrid. So far, the only way I've found to do it is like this: <mx:DataGridColumn headerText="Header" dataField="src" > <mx:itemRenderer> <mx:Component> <mx:ComboBox dataProvider="{data.srcChoices}" /> </mx:Component> </mx:itemRenderer> </mx:DataGridColumn> The problem is the initial value of the ComboBox isn't set correctly. If I hard code the choices, then the initial value is set correctly. I can't hard code the choices. Any idea what I should do?

• React to change on a static property

  - by Stiggler

  I'm re-writing an MXML item renderer in pure AS. A problem I can't seem to get past is how to have each item renderer react to a change on a static property on the item renderer class. In the MXML version, I have the following binding set up on the item renderer: instanceProperty={callInstanceFunction(ItemRenderer.staticProperty)} What would be the equivalent way of setting this up in AS (using BindingUtils, I assume)? UPDATE: So I thought the following wasn't working, but it appears as if Flex is suppressing errors thrown in the instanceFunction, making it appear as if the binding itself is bad. BindingUtils.bindSetter(instanceFunction, ItemRenderer, "staticProperty"); However, when instanceFunction is called, already initialized variables on the given instance are all null, which was the cause of the errors referenced above. Any ideas why this is?

• flex accessing children of a list component

  - by pfunc

  when I try to loop through the children of a List component that has buttons in it, I can't seem to access those children. I try for(var btnNum:Number = 0; btnNum < myList.numChildren; btnNum++) { trace(myList.getChildAt(btnNum); } but it is giving some other instance, not the button instances. and the weeklist <mx:List id="myList" dataProvider="{_data.mappoints.week.@number}" > <mx:itemRenderer > <mx:Component> <mx:Button buttonMode="true" toggle="true" alpha="1" width="116" height="35" label="WEEK {data}" > </mx:Button> </mx:Component> </mx:itemRenderer> </mx:List>

• Flex - Typed ArrayCollection as Horizontallist's dataprovider

  - by BS_C3

  Hi community! I have an ArrayCollection of objects. I'm passing this array to a horizontallist as a dataprovider and I'm using a custom itemRenderer. When executing the application, the horizontallist is displaying [object CustomClass][object CustomClass][object CustomClass][object CustomClass] I've tried casting each object in the itemrenderer as following: <mx:Label text="{(data as CustomClass).label1}"/> But it's not working... Thanks for any help you can provide. Regards, BS_C3 Edit - 09 March 2010 Let's go for some more code =) <?xml version="1.0" encoding="utf-8"?> <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Component id="Item"> <mx:VBox width="180"> <mx:HBox width="100%"> <mx:Spacer width="100%"/> <mx:Button label="x"/> </mx:HBox> <mx:Image id="thumbnail"/> <mx:Label width="100%" horizontalCenter="0" text="Collection"/> <mx:HBox width="100%"> <mx:Label width="100" text="GIA"/> <mx:Label text="{data.charg_st}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Finger Size"/> <mx:Label text="xxxxxx"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Carat"/> <mx:Label text="{data.carats}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Color"/> <mx:Label text="{data.color}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Clarity"/> <mx:Label text="{data.clarity}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Shop"/> <mx:Label text="{data.lgort_fp}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Resizing"/> <mx:Label text="{data.resizing}"/> </mx:HBox> <mx:HBox width="100%"> <mx:Label width="100" text="Price Excl.

Now, the horizontallist is displaying empty items... with the correct width... The arraycollection is not empty (I'm using an alert on the click event on an item, and I do retrieve the expected data). Hope this will help _< Regards, BS_C3

• TextArea being used as an itemEditor misbehaves when the enter key is pressed

  - by ChrisInCambo

  Hi, I have a TextArea inside an itemEditor component, the problem is that when typing in the TextArea if the enter key is pressed the itemEditor resets itself rather moving the caret to the next line as expected: <mx:List width="100%" editable="true" > <mx:dataProvider> <mx:ArrayCollection> <mx:Array> <mx:Object title="Stairway to Heaven" /> </mx:Array> </mx:ArrayCollection> </mx:dataProvider> <mx:itemRenderer> <mx:Component> <mx:Text height="100" text="{data.title}"/> </mx:Component> </mx:itemRenderer> <mx:itemEditor> <mx:Component> <mx:TextArea height="100" text="{data.title}"/> </mx:Component> </mx:itemEditor> </mx:List> </mx:Application> Could anyone advise how I can get around this strange behaviour and make the enter key behave as expected? Thanks, Chris

• How to customize data points on a Flex graph?

  - by Jess

  I have an area graph and I'm looking to have the data points to be shown. I have a CircleItemRenderer, but this shows all of the datapoints in the default stroke and fill. 1) How do I customize the display of my CircleItemRenderer? (instead of it having an orange fill, how can I change the color? 2) How can I decide to show the node for specific data points but not for others? For example, in my .XML file that imports the data for the graph, I may have a variable show_data_point which is true or false. Here's the current code I have: <mx:AreaSeries yField="numbers" form="segment" displayName="area graph" areaStroke = "{darkblue}" areaFill="{blue}" > <mx:itemRenderer> <mx:Component> <mx:CircleItemRenderer/> </mx:Component> </mx:itemRenderer> </mx:AreaSeries> </mx:series> Thanks a lot for your help!

• Flex custom list selection not highlighting

  - by aip.cd.aish

  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> <fx:Component> <mx:Canvas height="100"> <mx:Image height="90" width="120" source="{data.imageSource}"></mx:Image> <mx:Label left="125" y="10" text="{data.title}" /> <mx:Label left="125" y="30" text="{data.type}" /> <mx:Label left="125" y="50" text="{data.description}" /> </mx:Canvas> </fx:Component> </s:itemRenderer> </s:List>

• flex positioning a button within a panel

  - by pfunc

  All I'm trying to do is place a button inside of a panel, rotate that button (so it is vertical) and place it on the edge of the panel. I can;t seem to do this correctly. Here is my code: <mx:Panel id="weekList" width="260" height="100%" x="-500" title="Weeks" > <mx:List id="weekButtonList" width="260" borderVisible="false" contentBackgroundAlpha="0" dataProvider="{_data.mappoints.week.@number}" itemClick="onWeekClick(event);" > <mx:itemRenderer> <mx:Component> <mx:Button buttonMode="true" right="20" width="260" height="50" label="Week {data}" /> </mx:Component> </mx:itemRenderer> </mx:List> <mx:HBox id="closeButtonHolder" rotation="90" width="100" > <mx:Button label="OPEN" click="weekListToggle()" /> </mx:HBox> </mx:Panel> If you look at the part of the script you will see I am trying to rotate it and move it to the left. I am just trying to move it somewhere, and nothing is working. Also, the text seems to dissapear when I rotate it on a 90% axis. Anyone know what I can do for this?

• how to wordwrap in flex tree node

  - by Sam Jones

  I have a Tree object in my Flex code. It's width is 100%, and it is contained by a Panel with width=200. I am using a custom itemrenderer that extends TreeItemRenderer. I need the text in each node to word wrap if it's too big (as happens often). I have tried label.wordWrap = true; in my item renderer without any luck. Any other suggestions?

• Dynamic tab width in a Flex 4 TabBar component with skin

  - by JoriDor

  Hi, I have a Flex 4 TabBar component with a custom skin. In this skin, the item renderer is defined with an ButtonBarButton with a custom skin. All the tabs in the itemrenderer have now the same width. The client however wants me to make the tabs width dynamically, so a smaller tab for a smaller label, a bigger one for a long label. Does anybody know how to adjust the width of Tab (ButtonBarButton)? Thanks a million!

• flex: cant edit item in Datagrid with override set data method

  - by Markus

  Hi everybody, I've a custom itemRenderer for my datagrid. To set the actual data I use the following method: override public function set data(side:Object):void{ ... } As soon as I use this function the cell doesn't show up any item Editor anymore. Why is that? When I remove this function the itemEditor is working but with the wrong initialization data... What's the proper way to handle this? Thanks, Markus

• Flex: Using NumericStepper as an itemEditor in a DataGrid

  - by AlexH

  I am trying to make one field in a datagrid editable with a numeric stepper. My current attempts look like they are working, but the dataProvider is not actually being changed. Based on what I have read in a billion different places, the syntax should be < mx:DataGridColumn dataField="a" itemRenderer="mx.controls.NumericStepper" rendererIsEditor="true" editorDataField="value" / > I have tried several variations on this theme, and nothing seems to work. What am I missing?

• Very Strange behavior in custom dataGrid

  - by Markus

  Hi everybody, I asked this question already in a former post, but nobody could answer this question correctly. So I try to post the problem again, to make sure it's not a bug. I have a dataGrid with a custom itemRenderer. Everytime I tab at least two times on the dataGrid, the cell below the one I taped gets selected. This doesn't happen if I uncomment the code in the method saveBackDataGridContent()! The second problem is that if the Line is shorter than the entered text, a horizontalScrollBar will get active, although I set setStyle("horizontalScrollPolicy", "off");... Who can solve that one? CustomRenderer.mxml: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" initialize="dataService.send()"> <mx:Script> <![CDATA[ import components.ChoiceRenderer; import mx.rpc.events.ResultEvent; import mx.events.DataGridEvent; private function resultHandler(event:ResultEvent):void { var doc:XML = event.result as XML; testGrid.dataProvider = doc.Records.BackSide; } private function saveBackDataGridContent(event:DataGridEvent):void{ testGrid.dataProvider[event.rowIndex].TextElement = event.currentTarget.itemEditorInstance.text; } ]]> </mx:Script> <mx:HTTPService id="dataService" result="resultHandler(event)" url = "data/example.xml" resultFormat="e4x"/> <mx:DataGrid id="testGrid" editable="true" itemEditEnd="saveBackDataGridContent(event)"> <mx:columns> <mx:DataGridColumn itemRenderer="components.ChoiceRenderer" width="230"/> </mx:columns> </mx:DataGrid> </mx:Application> ChoiceRenderer.as package components { import mx.containers.HBox; import mx.controls.CheckBox; import mx.controls.Label; public class ChoiceRenderer extends HBox { private var correctAnswer:CheckBox; private var choiceLabel:Label; public function ChoiceRenderer() { super(); setStyle("horizontalScrollPolicy", "off"); correctAnswer = new CheckBox; addChild(correctAnswer); choiceLabel = new Label; addChild(choiceLabel); } override public function set data(xmldata:Object):void{ if(xmldata.name() == "BackSide"){ super.data = xmldata.TextElement[0]; choiceLabel.text = xmldata.TextElement[0].toString(); } } } } example.xml <TopContainer> <Records> <BackSide> <TextElement>first</TextElement> </BackSide> <BackSide> <TextElement>second</TextElement> </BackSide> <BackSide> <TextElement>third</TextElement> </BackSide> <BackSide> <TextElement>fourth</TextElement> </BackSide> <BackSide> <TextElement>fifth</TextElement> </BackSide> <BackSide> <TextElement>sixth</TextElement> </BackSide> </Records> Thanks Markus

• Having trouble with binding

  - by Tam

  I'm not sure if I'm misunderstanding the binding in Flex. I'm using Cairngorm framework. I have the following component with code like: [Bindable] var _model:LalModelLocator = LalModelLocator.getInstance(); .... <s:DataGroup dataProvider="{_model.friendsSearchResults}" includeIn="find" itemRenderer="com.lal.renderers.SingleFriendDisplayRenderer"> <s:layout> <s:TileLayout orientation="columns" requestedColumnCount="2" /> </s:layout> </s:DataGroup> in the model locator: [Bindable] public var friendsSearchResults:ArrayCollection = new ArrayCollection(); Inside the item renderer there is a button that calls a command and inside the command results there is a line like this: model.friendsSearchResults = friendsSearchResults; Putting break points and stepping through the code I confirmed that this like gets called and the friendsSearchResults gets updated. To my understanding if I update a bindable variable it should automatically re-render the s:DataGroup which has a dataProvider of that variable.

• FLEX: I lose current datagrid selection if I sort differently the items of its dataProvider.

  hi, when I sort differently my datagrid items, I lose the current selection. This is the code. I'm using savedSelectedItems array to restore the selectedItems but it doesn't work. How can I save the current selection. private function sortItems(option:String):void { //save selectedItems savedSelectedItems = tagsList.selectedItems; if (option == "tag") sort.fields = [new SortField("tag",true)]; if (option == "popularity") sort.fields = [new SortField("popularity",true)]; fullTagsDataModel.tagsData.sort = sort; fullTagsDataModel.tagsData.refresh(); tagsList.selectedItems = savedSelectedItems; } ... <!-- tags list --> <dataGrid:CheckBoxList id="tagsList" width="100%" height="100%" initialize="tagsList.dataProvider=fullTagsDataModel.tagsData" labelField="tag" itemRenderer="com.CheckBoxListAndDataGrid.CheckBoxRenderer" allowMultipleSelection="true" click="savedSelectedItems = tagsList.selectedItems" />

• search results filter effects - flex

  - by Adam

  I've created a search with a couple of comboboxes that allow users to filter their search results. The results are currently using a TileList & itemRenderer to display, and now I'd like to add an animation effect when the user filters their results. I know that you can use the itemsChangeEffect to create an animation effect when the user drags and moves result itmes. So I'd like to know if there's a way to create a similar effect triggered by the filtering on the comboboxes? Thanks.

• Flex TileList control, image loading issue

  - by ckenan

  I have a flex 3 TileList in wich a load several image (employee's headshot pictures). The image I'm loading in the TileList are stored in a DataBase (I use the ByteArray class and a Base 64 encoding to store the images in the DB). When I load the images in the TileList from the DB, there is no problem they are displayed correctly, but when I scroll down in the TileList and scroll up again, the position of the images is changing, so for example the image in first position can be now in the 3rd and so on .... Does somebody knows how to fix that ? Thanks in advance! PS : Here is the code of the ItemRenderer for the TileList private function init():void { img.load(data.imageData); } ]]

• flex datagrid re-assign dataprovider

  - by gauravgr8

  Hi, I am working on a datagrid with custom itemRenderer & [Bindable]xmllist as dataprovider. Now the changes done in xmllist are not reflected on datagrid UI until unless I re-assign the dataprovider as the same xmllist. As the dataprovider is Bindable so re-assigning is not required. But it was not working so I re-assigned the xmllist to the dataprovider of datagrid. It worked. Now my problem is when I re-assign the dataprovider my datagrid flicker(refreshes). It should not happen. 1) Is there any way out to avoid re-assigning of dataprovider? 2) Is there any way to stop flickering of datagrid on re-assigning the dataprovider? Thanks in advance.
