-------------------------------------------------------------------
Trying the fix on my side:
Since I don't know how (& don't have time) to download and compile the develop
branch, I subclassed DateField and overridden measure() with the fixed code
(see code below).
Unfortunately, the scrolling still occurs on my environment.
Note: maxWidth is set to 62 at the end of the loop, and bigDate width was also
62 pixels prior to the fix.
What do you think ?
{code}
package controls {
import mx.controls.DateField;
import mx.core.mx_internal;
use namespace mx_internal;
public class DateFieldExt extends DateField {
public function DateFieldExt() {
}
override protected function measure():void {
// skip base class, we do our own calculation here
// super.measure();
var buttonWidth:Number = downArrowButton.getExplicitOrMeasuredWidth();
var buttonHeight:Number = downArrowButton.getExplicitOrMeasuredHeight();
// copied from sdk develop branch
var bigDate:Date;
var txt:String;
var textWidth:Number;
var maxWidth:Number = 0;
// Width may vary based on date format
for (var month:int = 0; month < 12; month++) {
bigDate = new Date(2000, month, 28); // day 28
exist in all months
txt = (labelFunction != null) ?
labelFunction(bigDate) : dateToString(bigDate, formatString);
textWidth = measureText(txt).width;
if (textWidth > maxWidth) {
maxWidth = textWidth;
}
}
measuredMinWidth = measuredWidth = maxWidth + 8 + 2 + buttonWidth;
measuredMinWidth = measuredWidth += getStyle("paddingLeft") +
getStyle("paddingRight");
measuredMinHeight = measuredHeight =
textInput.getExplicitOrMeasuredHeight();
}
{code}

> DateField text scrolled when pressing DateField calendar button

> Key: FLEX-24257
> URL: https://issues.apache.org/jira/browse/FLEX-24257
> Project: Apache Flex
> Issue Type: Bug
> Components: mx: DateField
> Affects Versions: Adobe Flex SDK 3.2 (Release)
> Environment: Affected OS(s): Windows
> Affected OS(s): Windows 7
> Browser: Internet Explorer 8.x
> Language Found: English
> Reporter: Adobe JIRA
> Assignee: Justin Mclean
> Fix For: Apache Flex 4.10.0
>
> Attachments: screenshot-1.jpg
>
>
> Steps to reproduce:
> 1. Click on an editable DateField's calendar button when the DateField
> doesn't currently have focus.
> 2. Observe the text in the DateField's textinput area.
>
> Actual Results:
> The text is automatically highlighted and scrolled to the left such that the
> beginning part of the date text isn't visible.
>
> Expected Results:
> The text should not be highlighted or scrolled at all.
>
> Workaround (if any):
> Click in the textinput area before pressing the button.
>
> Sample app:
> <?xml version="1.0" encoding="utf-8"?>
> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="vertical">
> <mx:DateField editable="true"/>
> </mx:Application>
> I see this on Flex SDK 3.2, 3.4 and 4.0.
