Maurice Amsellem updated FLEX-34107:
------------------------------------
Comment: was deleted
(was: 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.
So that explains the symptoms you describe: when there is enough padding
around the renderer, the extra sizing the internal label has no effect.
