I have multiple HBoxes inside a VBox inside a canvas like so:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:local="*">
<mx:Canvas width="600" height="500">
<mx:VBox height="100%" left="10" right="10">
<mx:HBox width="100%" >
<mx:VBox width="48%" height="100%" horizontalAlign="left">
<mx:Label text="Label" />
</mx:VBox>
<mx:VBox width="48%" height="100%" horizontalAlign="left">

<mx:HBox width="100%">
<mx:VBox width="48%">

</mx:VBox>

The last child in the VBox is overlapping with other components. How do you prevent children of a VBox in a Canvas from overlapping? How do you debug this situation?
I have tried the following:
Removing percent based sizing
IncludeInLayout = true
Sceenshot - Label and Checkbox Overlapping:
It's hard to say with the information provided, but the two questions that come to mind first are:
Is your VBox height greater than the sum of the heights of its children?
Have you set the verticalGap property on the VBox? verticalGap determines vertical spacing between children.
I just tried this (AIR app) and it looks alright to me.
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Canvas height="100%" width="100%"
borderStyle="solid"
backgroundColor="0x0000ff">
<mx:VBox height="100%" width="100%">
<mx:VBox backgroundColor="0xff0000" height="50%" width="100%">
<mx:HBox backgroundColor="0x000000" height="50%" width="50%"/>
<mx:HBox backgroundColor="0xffffff" height="50%" width="50%"/>
<mx:HBox backgroundColor="0x00ffff" height="50%" width="50%"/>
</mx:VBox>
<mx:HBox height="50%" width="100%"
backgroundColor="0xff0000" backgroundAlpha="0.5"
borderColor="0x000000" borderStyle="solid" borderThickness="1"/>
</mx:VBox>
</mx:Canvas>
</mx:WindowedApplication>
I resolved this by making the includeInLayout property of some of these components the same conditional used by their visible property.
Not sure what caused the issue though.

I want the TextArea under my second tab to update when the tab is clicked. However, it's only updating when I click on the TextArea or the container for that text area.
Flex:
<mx:Box paddingLeft="0" paddingRight="0" paddingBottom="0" paddingTop="0" width="100%" height="100%"
<mx:VBox id="vbxHTMLBody" width="100%" height="100%" horizontalScrollPolicy="off" horizontalAlign="center">
<mx:TabNavigator id = "tabNav" borderStyle="solid" width="100%" height="100%" creationPolicy="all">
<mx:VBox label="Tab1" width="100%" height="100%">
<mx:TextArea id="textArea1" paddingTop="25" paddingLeft="25" paddingRight="25" verticalScrollPolicy="on" focusThickness="0" borderThickness="0" borderStyle="none" editable="true" fontFamily="Arial" fontSize="14" width="100%" height="100%"/>
</mx:VBox>
<mx:VBox label="Tab2" width="100%" height="100%" click="updateTextArea2()">
<mx:TextArea id="textArea2" paddingTop="25" paddingLeft="25" paddingRight="25" verticalScrollPolicy="on" focusThickness="0" borderThickness="0" borderStyle="none" editable="true" fontFamily="Arial" fontSize="14" width="100%" height="100%"/>
</mx:VBox>
</mx:TabNavigator>
</mx:VBox>
</mx:Box>
ActionScript:
private function updateTextArea2(): void {
textArea2.htmlText = textArea1.text;
tabNav.validateNow();
textArea2.validateNow();
}
*I've also tried setting the click listener to the outer containers and that hasn't worked either.
I used change="updateTextArea2()" to listen for any changes made to the text area.
Call updateTextArea2()on change of the TabNavigator:
<mx:TabNavigator id="tabNav" change=updateTextArea2()">
instead from VBox change.
My Flex MX list has this itemRenderer
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" width="100%" autoLayout="true" horizontalScrollPolicy="off">
<mx:Label y="0" right="0" text="{data.hour}" textAlign="right"/>
<mx:HBox left="0" right="0">
<mx:Label text="{data.username}" />
<mx:Text id="text1" text="{data.text}"/>
<mx:Image />
<mx:Button />
</mx:HBox>
</mx:Canvas>
My problem is : I want the MX Text id="text1" to be multi line if {data.text} grows.

Use the following code : Please adjust the width of spacer according to your alignment requirements. Also Dont miss out mentioning the width of every HBox and VBox inside the formItem. Here, I am using all mx components.
<mx:Form>
<mx:FormItem width="100%">
<mx:VBox id="ContainerVBox" width="100%">
<mx:HBox width="100%">
<mx:Label id="label1" text="my label here"/>
<mx:Spacer width="10%"/>
<mx:TextInput id="textInput1" text="This is text input 1"/>
</mx:HBox>
<mx:TextInput id="textInput2" text="This is text input 2"/>
</mx:VBox>
</mx:FormItem>
<mx:FormItem width="100%">
<mx:HBox width="100%">
<mx:Label id="label1" text="my label here"/>

How do I add a border to a Flex VBox? My VBox is the renderer of a List. I've tried the following without success (in particular VBox's borderVisible="true" borderStyle="solid" borderColor="0x888888"):
<mx:List id="myList" dataProvider="{myData}"
width="100%" height="100%"
variableRowHeight="true"
verticalScrollPolicy="auto" horizontalScrollPolicy="auto">
<mx:itemRenderer>
<mx:Component>
<mx:VBox
width="100%" height="100%"
verticalScrollPolicy="off" horizontalScrollPolicy="off"
borderVisible="true" borderStyle="solid" borderColor="0x888888">
<mx:HBox width="100%">
<mx:Label id="firstNameLabel" text="{data.firstName}"/>
<mx:Label id="lastNameLabel" text="{data.lastName}"/>
</mx:HBox>
<mx:Text id="descriptionLabel" text="{data.description}"/>
</mx:VBox>
</mx:Component>
</mx:itemRenderer>
</mx:List>
There is no borderVisible style or property on the Flex Container classes.
To see a border you need to set the borderStyle, borderColor and borderThickness styles.
Try the following styles for your VBox:
<mx:VBox
borderThickness="1" borderStyle="solid" borderColor="0x888888" ...>
...
</mx:VBox>
And in actionscript 3:
private var _vbox:VBox;
...
this._vbox.setStyle("borderThickness", "1");
this._vbox.setStyle("borderStyle", "solid");
this._vbox.setStyle("borderColor", "0x888888");

borderVisible is nothing in flex, use borderStyle=solid, borderThickness, and borderColor attributes to show border
Hy,
Is it possible to resize the application at the same moment when the Accordion size change, to make effect resize og the last one synchronised with resize of Application ?
In my code,, the Application is resized after the resize of Accordion is completed:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute" minWidth="400" minHeight="300" backgroundColor="white" horizontalScrollPolicy="off" verticalScrollPolicy="off" mouseDown="stage.nativeWindow.startMove()">
<mx:Resize id="expand" target="{application}" heightTo="{acc01.height}"/>
<mx:Accordion id="acc01" x="0" y="0" resizeToContent="true" resize="expand.play();" horizontalScrollPolicy="off" verticalScrollPolicy="off">
<mx:VBox label="Accordion Pane 1" width="100%" height="100%">
<mx:Label text="hello"/>
<mx:Label text="hello"/>
<mx:Label text="hello"/>
<mx:Label text="hello"/>
</mx:VBox>
<mx:VBox label="Panel 2" width="100%" height="100%">
<mx:Label text="hello"/>
<mx:Label text="hello"/>
</mx:VBox>
<mx:VBox label="Panel 3" width="100%" height="100%">

<mx:Label text="hello"/>
</mx:VBox>
</mx:Accordion>

Have a look at http://livedocs.adobe.com/flex/3/langref/mx/effects/Parallel.html, it might do what you need.
