scaleContent property is true, but the UILoader is not resized ?

Resizes the component to the requested size. If the scaleContent property is set to true, the UILoader is not resized.



import fl.containers.UILoader;

var myUILoader:UILoader = new UILoader();
myUILoader.source = "http://www.helpexamples.com/flash/images/image2.jpg";
myUILoader.addEventListener(Event.COMPLETE, completeHandler);
addChild(myUILoader);

function completeHandler(event:Event):void {
var uiLdr:UILoader = event.currentTarget as UILoader;
var image:DisplayObject = uiLdr.content as DisplayObject;
trace("UILoader:", uiLdr.width, uiLdr.height); // 100 100
trace("UILoader.content:", image.width, image.height); // 400 267
uiLdr.setSize(image.width, image.height);
uiLdr.move((stage.stageWidth - image.width) / 2, (stage.stageHeight - image.height) / 2);
}

Automatically resize Text/TextArea based on content (autoSize) in Flex

by Nicolas Noben

UPDATE: turns out that doesn’t always work. the autoSize property is not reliable at all…

This, should do!

var ta_height:uint = 25;

field.validateNow();

for(var i:int=0; i < field .mx_internal::getTextField().numLines; i++) {
 ta_height += field.mx_internal::getTextField().getLineMetrics(i).height;
}

derivedHeight = ta_height;

Thanks Vaan.

Original post:

Adobe’s dodgy textHeight sure doesn’t do the trick. I end up getting a textfield of 2000px height while it clearly looks like 300 tops.

This, however, works.

the code

private function resizeMe(field:TextArea) :void
{
 field.validateNow();
 field.mx_internal::getTextField().autoSize = TextFieldAutoSize.LEFT;
 field.height = field.mx_internal::getTextField().height;
}

Just use that on your TextArea or Text component:

creationComplete="resizeMe(this.myTextAreaInstance)"
