Subject [jira] [Commented] (FLEX-24257) DateField text scrolled when pressing DateField calendar button

Maurice Amsellem commented on FLEX-24257:
-----------------------------------------

Double-testing the fix:
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}

> 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>
