Subject [jira] [Commented] (FLEX-34107) IconItemRenderer separators dissapear on iPad 2 iOS6
Date Sun, 23 Feb 2014 13:03:19 GMT

    [ https://issues.apache.org/jira/browse/FLEX-34107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13909759#comment-13909759

Maurice Amsellem commented on FLEX-34107:
-----------------------------------------

I did some more testing to validate the opaqueBackground assumption.

I made two tests:
- UIComponent displaying a colored rect and having opaque background => both extents match
- UIComponent displaying a colored rect, a text label (StyleableTextField) and having opaque
background => opaque background exceeds the component extent.

so it seems that the text is the cause of the background overflow.
Explanation:
- opaqueBackground extent is based on the component's children extents, and not on the UIComponent
size.
- when you set a height of H to a StyleableTextField, AIR will give it around H+10%
=> so if you set the extent of the text child to 100% of UIComponent, the opaqueBackgound
with overflow, because the text actual extent is 110% of the UIComponent.

To prove this, simply show the text own background:
{code}
     labelDisplay = StyleableTextField(createInFontContext(StyleableTextField));
 ...
      labelDisplay.background = true;
      labelDisplay.backgroundColor = 0xFF0000;
{code}

And you can see that the text background and the opaque background of its parent match.

QED.

> I have two spark List one with IconItemRenderer and the second with LabelItemRenderer.

> List with IconItemRenderer doesn't display line separators on iPad 2 iOS6. It also occurs
on iPhone and iPad Intellij IDEA emulators.
