I have a list component in my app which shows some tiles and one can navigate through them horizontally and i was wondering how can i add the swipe functionality in it to the left or to the right,is this supported by default when the app is on a touch device? the list is like:
<s:List id="list2" width="100%" height="100%" dataProvider="{ recordingsShown }"
preinitialize="list2_preinitializeHandler(event)"
selectedIndex="0" visible="false">
<s:layout>
<s:TileLayout id="tilelayout"
useVirtualLayout="true"
orientation="columns"
columnAlign="justifyUsingWidth" rowAlign="justifyUsingHeight"
requestedColumnCount="3"
requestedRowCount="2"
paddingBottom="5" paddingLeft="5" paddingRight="5" paddingTop="5"
verticalGap="10" horizontalGap="10" />
</s:layout>
</s:List>
any help?
Have you tried
list2.addEventListener(TransformGestureEvent.GESTURE_SWIPE, onSwipe)
?
That should do the trick.

I have two tilelists in my mxml application. The items (image and a label) get rendered by an itemrenderer. The functionality I want to achieve: drag image from tilelist #1 and drop it on tilelist #2 (and then a httpservice with sql query will be launched).
How would I tackle this problem? (high level info would suffice).
The main issue I have is that I don't know how to call methods from the main to my itemrenderer. I would like to code the d&d functionality within the renderer but I have no clue how to access watchlist #2 from within the renderer.
Relevant code in main.mxml:
<s:Panel id="panel" width="100%" height="100%" title="Watchlist">
<s:layout>
<s:VerticalLayout paddingBottom="5" paddingLeft="20"
paddingRight="20" paddingTop="5"/>
</s:layout>
<s:Label width="20%" fontSize="17" fontWeight="bold" text="Your watched movies"/>
<mx:TileList id="myWatchedList_tile" height="360" borderVisible="false" width="80%"
columnCount="5" columnWidth="200"
itemRenderer="components.TileListItemRenderer" rowCount="1" rowHeight="360"/>
<s:Label width="20%" fontSize="17" fontWeight="bold" text="Your to watch movies"/>
<mx:TileList id="myToWatchList_tile" height="360" borderVisible="false" width="80%"
columnCount="5" columnWidth="200"
itemRenderer="components.TileListItemRenderer" rowCount="1" rowHeight="360" />
</s:Panel>
The itemrenderer:
<?xml version="1.0" encoding="utf-8"?>
<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml"
borderVisible="false" horizontalAlign="center" verticalAlign="middle"
xmlns:components="components.*">
<mx:Image source="{data.poster_url}" />
<mx:Label text="{data.movie_title}" height="20" />
</mx:VBox>
You can access methods outside of your item renderer using the outerDocument object. Make sure they are (scope)public methods.

Alternative solution might be to use spark lists instead (with a TileLayout) - then you can easily use drag+drop between lists: http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-7cfd.html
..and launch service in response to 'drop' event (event will have reference to dropped image)
I've created a skin that allows me to have two labels on a spark button, but the button text won't center vertically. It stays at the top of the button no matter what settings I give it. The icon in the skin DOES however, center vertically.
This is the skin:
<s:SparkButtonSkin xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:fb="http://ns.adobe.com/flashbuilder/2009"
minWidth="82" minHeight="82"
alpha.disabled="0.5" initialize="autoIconManagement=false">
<fx:Metadata>[HostComponent("com.XXXX.components.TwoLineButton")]</fx:Metadata>
<!-- states -->
<s:states>
<s:State name="up" />
<s:State name="over" />
<s:State name="down" />
<s:State name="disabled" />
</s:states>
<s:Image source="{getStyle('upSkin')}"
source.over="{getStyle('overSkin')}"
source.down="{getStyle('downSkin')}"
source.disabled="{getStyle('disabledSkin')}"
width="100%" height="100%"
/>
<s:HGroup verticalAlign="middle" height="100%" width="100%"
paddingLeft="{getStyle('paddingLeft')}"
paddingRight="{getStyle('paddingRight')}"
paddingTop="{getStyle('paddingTop')}"
paddingBottom="{getStyle('paddingBottom')}"
gap="{getStyle('horizontalGap')}"
verticalCenter="0">
<s:BitmapImage id="iconDisplay" includeInLayout="{iconDisplay.source}"/>
<s:VGroup gap="{getStyle('verticalGap')}" height="100%" width="100%">
<s:Label id="labelDisplay"
textAlign="center"
width="100%"
maxDisplayedLines="1"
horizontalCenter="0" verticalCenter="1" verticalAlign="middle"
left="10" right="10" top="2" bottom="2">
</s:Label>
<s:Label id="bottomLabelDisplay"
textAlign="center"
width="100%"
maxDisplayedLines="1"
horizontalCenter="0" verticalCenter="1" verticalAlign="middle"
left="10" right="10" top="2" bottom="2">
</s:Label>
</s:VGroup>
</s:HGroup>
This is the code I'm calling it with:
<components:TwoLineButton
width="308"
label="TopLabel"
bottomLabel="Bottom label"
click="handleButtonClick(event)"
/>
I've tried making the HGroup use a hardcoded height value, and that doesn't work either.
Thanks in advance.
You cannot use absolute constraints like 'x', 'y', 'left', 'right', 'top', 'bottom', 'horizontalCenter', 'verticalCenter', ... inside a relative layout like VerticalLayout (VGroup is just a Group with a VerticalLayout). This makes sense since you can't position something both relatively and absolutely. In this case the layout of the container takes precedence over whatever constraints you put on the child component. This means you can simply remove any of these constraints you have there: they simply don't have any effect.
Also 'verticalAlign' is a style you apply to a container, but it tells the container how to layout its children. You've assigned it to the Labels, so you're saying "lay out the text component inside the Label in the middle of the Label component" and not "layout the Label component in the middle of the VGroup". So this one is also redundant.
Something like the following should fix your issue:
<s:VGroup height="200">
<s:Label text="A" height="50%" verticalAlign="middle" />
<s:Label text="B" height="50%" verticalAlign="middle" />
</s:VGroup>
or if you want both Labels grouped together in the middle of the VGroup (it's not apparent from the description which one of both you want):
<s:VGroup height="200" verticalAlign="middle">
<s:Label text="A" />
<s:Label text="B" />
</s:VGroup>
The HGroup in your skin should look something like this:
<s:HGroup verticalAlign="middle" height="100%" width="100%"
paddingLeft="{getStyle('paddingLeft')}"
paddingRight="{getStyle('paddingRight')}"
paddingTop="{getStyle('paddingTop')}"
paddingBottom="{getStyle('paddingBottom')}"
gap="{getStyle('horizontalGap')}" >
<s:BitmapImage id="iconDisplay" includeInLayout="{iconDisplay.source}"/>
<s:VGroup gap="{getStyle('verticalGap')}" width="100%" verticalAlign="middle" >
<!-- not sure if you need 100% width here -->
<s:Label id="labelDisplay"
textAlign="center"
width="100%"
maxDisplayedLines="1">
</s:Label>
<s:Label id="bottomLabelDisplay"
textAlign="center"
width="100%"
maxDisplayedLines="1">
</s:Label>
</s:VGroup>
</s:HGroup>
Your labels are in a VGroup so attributes like verticalCenter, horizontalCenter, top, left, etc. do not apply. These attributes only work in BasicLayout (absolutely positioned layouts).
I also removed the 100% height on the VGroup that contained the labels. This means that group of labels will only be as tall as necessary (so now we can actually center it).
Finally, added verticalAlign="middle" to the VGroup. Since the parent of this group is an HGroup, the VGroup should be positioned horizontally next to the BitmapImage if present, and vertically aligned in the middle.
I'm trying to create a custom view (one that is not 100% listview, for example), mix and matching images and labels.
One issue is that when the label overflows greater than the screen height, the rest just gets off. I had assumed scrolling or touch-drag scrolling would be automatically enabled? How do you enable the touch-drag scrolling that happens naturally in list view?
I wrap all the visual elements of my View inside a Scroller - this will solve that problem
<s:Scroller id="scroller" left="10" right="10" top="10" bottom="10" >
<s:VGroup paddingTop="3" paddingLeft="5" paddingRight="5" paddingBottom="3" horizontalAlign="center">
<s:HGroup horizontalAlign="right" width="100%">
<s:Image scaleMode="letterbox" source="#Embed('images/small_background.GIF')"/>
</s:HGroup>
<s:TextInput id="txtUsername" prompt="Enter user name..." fontFamily="Arial"/>
<s:TextInput id="txtPassword" prompt="Enter password..." fontFamily="Arial"
displayAsPassword="true" />
<s:Button />
<s:Button />
</s:VGroup>
</s:Scroller>
Apologies for the rookie Q - trying to learn Flex/Actionscript and just having some basic layout issues. (Using FlashBuilder 4, with Flex 4.5 HERO SDK)
I have a TitleWindow, and have embedded a mx:TabNavigator within it.
I have then placed a list within the first tab and set its width/height to 100%
However, there appears to be a gap between the top of the list, and the bottom of the tab menus.
Why is this happening and what is the best way to ensure the top of the list aligns up flush with the top of the VBox?
<s:TitleWindow title="Dekho Resource Center"
id="titleWindow"
close="cancel();"
width="375"
height="500"
backgroundAlpha="0"
cornerRadius="5">
<mx:TabNavigator borderStyle="solid" left="0" top="0" width="100%" height="100%" backgroundAlpha="0" >
<mx:VBox label="Blog Posts"
width="100%"
height="100%">
<s:List labelField="title" id="theList" width="100%" height="100%"
contentBackgroundAlpha="0.7" rollOverColor="#F58B57" selectionColor="#FF7227"
doubleClickEnabled="true" doubleClick="theList_doubleClickHandler(event)">
<mx:AsyncListView list="{getDataResult.lastResult}"/>
</s:List>
</mx:VBox>
<mx:VBox label="Search"
width="100%"
height="100%">
</mx:VBox>
</mx:TabNavigator>
Remove the padding from the TabNavigator:
<mx:TabNavigator paddingTop="0"
paddingLeft="0"
paddingRight="0"
paddingBottom="0">
Im very new to Adobe Flex/Actionscript and am trying to create a person search application. So far I have my results showing as a horizontal list, but Id like to include an image above each name as my wonderful paint skills show:
/* listOfPeople is a list of arrays with a["name"] a["sex"] a["dob"] and
a["image"] which is just a URI to the image */
<s:List width="100%" height="100%" id="results" dataProvider="{listOfPeople}" change="clickPerson(event)">
<s:itemRenderer>
<fx:Component>
<s:MobileIconItemRenderer
iconField="{data.image}"
iconHeight="100" iconWidth="100"
label="{data.name} - {data.sex}"
messageField="dob"/>
</fx:Component>
</s:itemRenderer>
<s:layout>
<s:HorizontalLayout paddingBottom="100" gap="6" paddingTop="100" paddingLeft="0"
paddingRight="0"
requestedColumnCount="-1"
variableColumnWidth="true"
verticalAlign="bottom"
/>
</s:layout>
</s:List>
Any ideas? The iconField doesn't seem to show at all... even when using the full path with correct backslashes
Cheers
Phil
EDIT:
The image displays fine on the PersonDetails screen, when the person is clicked upon:
<s:HGroup verticalAlign="middle" gap="12" paddingTop="10" paddingLeft="10">
<s:Image source="{data.image}" height="170" width="170"/>
<s:VGroup>
<s:Label text="{data.name}"/>
<s:Label text="{data.dOB}"/>
<s:Label text="{data.sex}"/>
<s:Label text="{data.birthplace}"/>
<s:Label text="{data.colour} {data.ethnicity}"/>
<s:Label text="{data.height}"/>
</s:VGroup>
</s:HGroup>
I think MobileIconItemRenderer displays all elements in a horizontal layout. If you want to display an image on top of the text, you have to create your own renderer or extends MobileIconItemRender and change the way it layouts its elements
