This seems to be a regression-without-cure between AS2 and AS3. In AS2 I could write:
txt.wordWrap=true;
txt.align="center";
txt.htmlText="blah, blah, blah";
and each line in that text field would be centered.
In AS3 I am writing:
txt.wordWrap=true;
txt.align=TextFieldAutoSize.CENTER;
txt.htmlText="blah, blah, blah";
but it ends up left-aligned.
The bigger problem is that this is the documented behaviour: if wordWrap is set then align will not center text.
So, how do I center a multi-line text field?!!
(Time passes.)
I cannot believe there is nothing on the web about this. Have all the flash developers in the world stopped centering their text, or am I missing something obvious?
(More time passes.)
OK, after some trial-and-error I have a workaround, which sucks but will get the job done:
CopyA.htmlText='<body><p align="center">blah, blah, blah</p></body>';
Why do I say this sucks? Because I cannot (easily) apply it afterwards: I will need to get the current htmlText contents, detect the body tag and insert after it; and a corresponding closing-P tag at the end.
But in this application the text string comes from a DB and is allowed to contain HTML tags. What if it too already has a P tag? Will I get an extra blank line? Are P tags allowed to be nested?
(Well, I just tried, and it seems fine still, and if the inner P tag has an align that is the one that gets applied. So all good there.)
UPDATE: I discovered I can also write this:
CopyA.htmlText='<p align="center"><body>blah, blah, blah</body></p>';
That is dubious, and I wonder if it is future-proof, or if I am exploiting a bug? But it is obviously far easier, as it saves me having to do any parsing - I can just wrap whatever the existing htmlText is:
copyA.htmlText='<p align="center">'+copyA.htmlText+'</p>';
