Flex :: How To Set TextArea Height According To Its Content

Jun 21, 2010

I have an mx:TextArea and I want its height to be the same as its content height. There is nothing fancy - just a text area and text that is not editable. I need a simple and reliable way to make the control fit and show all the text without vertical scroll - something like auto resizing. Also my control's text will be set only once and will not change as it will not be editable.

<mx:TextArea id="myTextArea"
editable="false"
width="100%"
verticalScrollPolicy="off" >
<mx:text>
[Code] .....

There is one more post here on the same topic but it is not relevant to me because the setup there is a lot more complicated as it includes styling and binding.

The contents of the flex app are very dynamic, and I don't want to have an extra scroll bar when there is already one. So is there a way to make the height of the swf match the height of the contents of the swf?

Flex :: Having The Content Of A S:Scroller Viewport At 100% Height

Jul 27, 2010

Is there a way to get the content of a component inside a scroller to be at 100% height.

here is a simple example:

<s:Scroller width="100%" height="100%">
<s:viewport>
<s:Group height="100%">

[Code]....

As you can see, the green bar (set at 100% height) is just using the height of the viewport, not that of it's parent group, that is stretched by the red one to be 500px high.

ActionScript 3.0 :: Height Of Scrollbar To Height Of Scrolling Content?

Nov 8, 2009

I made a scrollbar class that works pretty well. I'm trying to come up with an idea for how to set to the height of the scrollbar vs the height of the scrolling content. This is a standard thing that happen in the OS. Seems there should be a minimum number and the maximum value should be reached as the size of the content approaches the size of the visible area.

Actionscript 3 :: Why Is Spark TextArea Tiny When A Height And Width Are Set

Jul 19, 2010

The problem, as you can see, is that the text (height and width) is nothing like the Height and Width of the compoent (Spark TextArea) that I have set via the Main.mxml file in Flex 4. This is pissing me off so much because nobody can tell me why this is happening, or how to fix it. Text is dynamically added to the TextArea as people send messages in the server, hence the valueCommit line.I don't understand this, because I know it's not the fault of my fx:Script. I know this, because when I switch over to the Design tab of Adobe Flex Builder 4; the lines are just as messed up as in the screen shot.[code]

Bind A Flex Component's Height To Height Of Browser Window?

Nov 10, 2009

I want to constrain the height of a flex component to the height of the browser viewport.

The component's children are populated from a database table using a repeater, and are basic checkboxes. There are enough of them that the flex app ends up being about twice the height of the screen, which means some of the rest of the layout goes crappy on me. How can I force the component that contains these to limit itself to the size of the viewport?

Flex :: Layout - Set Height Of Accordion To Height Of Tallest Child

Apr 5, 2010

By default the height of an Flex Accordion container is the height of the initially selected child. I'd like to be able to set the height to the tallest child so that no resizing or scrolling is necessary when other children are selected. I do not want to use the resizeToContent property. I want the size of the container to stay constant no matter what child is selected.

My current thought is to extend the accordion class setting the creation policy to "all" and then override the measure function to loop through all the children and find the tallest one and use that for the height. This seems a little kludgy though, so I'd like to know if there is a better approach. Ultimately my question is: is there a way to set the size of an accordion container such that the container never resizes and scoll bars are never necessary to display any of the children?

Flash :: Adjusting 4 Scroller Height To Content

Aug 26, 2010

I am having a little difficulty properly sizing a Scroller component in Adobe Flex/Flash 4. As soon as I add an element to the 'widgetsGroup' VGroup, the scroller's height property resizes to match that of its parent border container, even though the content height of the vGroup may be significantly less than this value. This is a problem because the scroller then 'covers' other elements in the border container. I guess what I am looking for is the scroller height to match the widgetGroup content height until this height exceeds the bordercontainer height, at which point the scroll bar would become visible.

Actionscript 3 :: Align The Content Of A TextField, But Keep Its Width X Height

Mar 16, 2012

In a card game I use a TextField in the middle to display the playing table number, but also to detect if a playing card has been played - using myTextField.hitTestObject(myCard) - which means the TextField's position and dimensions may not change:

My current AS3 code is:

var format:TextFormat = new TextFormat();
format.color = 0xFFFFFF;
format.size = 30;

[Code]......

However the TextField's content (the String "#2029" in the above screenshot) is not in the center of it.

I can not set _middle.autoSize = TextFieldAutoSize.CENTER because this changes the width of the border (and breaks hitTestObject()).

Is there another way to align the text in the middle?

ActionScript 3.0 :: Ignoring Content Outside Of Mask When Calculating Height?

Flex :: VBox Doesn't Add Child If All The Objects' Height Over The VBox's Height?
