How to express a newline in a Label within BXML?
Thanks everyone for your help so far! I've yet another question.
How do I place a newline in a Label's text in BXML? I see that in 2.0.3,
Pivot began supporting text labels with hard newlines with the "\n"
character (
http://mail-archives.apache.org/mod_mbox/pivot-commits/201301.mbox/%3C20130122010418.3EC4223889F7@eris.apache.org%3E),
but this seems only to work programmatically.
As a workaround, I've tried the following things, which all fail:
- Placing "\n" as the value of the text attribute in the label in BXML.
This shows up as "\n" in the application, and "\\n" when viewing the
label.getText() result
- Using "\\n" as the value instead, in hopes that the double backslash
might escape. It does not, and the label text appears as "\\n" in the app.
- Doing label.setText(label.getText()) with 'text="\n" in BXML'. Doesn't
work because the "\n" is already escaped to "\\n". I suppose I could do a
replace of "\\" with "\" before setText(), but it seems inelegant to have
to initialize all labels like this.
Other than setting the label programmatically, any tips? Note that setting
the value programmatically does work for me. I've got "wrapText:true" set
in my tests.
Thanks!

Great!
I've just now updated the "label_test.bxml" file in "trunk" so it has a
couple of these hard-coded newlines just as an example for others. To
use it, navigate to the "tests/src/org/apache/pivot/tests" directory and
do: "java org.apache.pivot.wtk.ScriptApplication
--src=.\label_test.bxml"

It works for me! The answer seems kind of obvious, in retrospect =)

So to set a newline in a bxml file you have to use the XML escape mechanism(s). That's all. For example: or

Hi Erik,
you have reason, currently I find multiline label samples only in
LabelTest.java class, I have to add a bxml version of it ...
Searching in our sources, I find other examples for multiline strings
(in bxml files), but for other components (TableView, and related
renderers), like: table_pane_test2.bxml, table_pane_test4.bxml ... but
these could be a starting point. Could you do some tests starting from
here ?
Anyway this could be a BXMLSerializer issue (LabelSkin does the line
splitting if it finds the \n snside the label text , but as a single
char), so we have to verify it.
Roger, what do you think ?
Let's update.
