Song,
If I am not mistaken, the "\n" in your constant string that pass to
setText is interpreted by the compiler and replaced with an actual
newline character in the string (rather than the \n escape code) that
gets included in your binary.
Your XML string that is read from a file, on the other hand, contains
the actual two characters "\" and "n", which mean nothing special at run
time unless they are passed through a function that looks for them and
replaces them with an actual new line character.
On a side note, you can put an actual new line in your XML file and have
it come through correctly in the parsed XML file (which can then be
passed straight to the button. For example:
<outer>
<inner>Line one
Line two</inner>
</outer>
The text of <inner> will be:
Line one
Line two
This is what you want instead of <inner>Line one\nLine two</inner>,
since that will produce a text of "Line one\nLine two", with the \n
instead of a new line.
Hope that helps,
Harold

Hi,
I'm trying to set the label on a QPushButton from an XML file. For
example, the label is "A very long\nbutton name", basically the idea is
to split it so it can fit on the button. But for some reason the button
does not interpret the new line ("\n") character. But
myButton->setText("A very long\nbutton name") does work.
Does this have anything to do with encoding?
thanks
Song
