Description Andreas Stangl 2009-07-05 13:14:19 UTC 
Version:           1.0 (using KDE 4.2.4)
Compiler:          gcc-4.3.3 CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=native -O2 -pipe -fomit-frame-pointer"m CHOST="x86_64-pc-linux-gnu"
OS:                Linux
Installed from:    Gentoo Packages

It seems that kdialog can not identify escaped \n (= \\n), the \n is does always result in a newline. When I try to replace the backslash character with the html entity \ then #92; is displayed instead of the backslash. (see screenshot)

I came up to this problem when trying to display a windows-like path that is passed to wine.

Unable to escape \n

The upper kdialog call is unable to escape \n via \\n.
The lower call shows that kdialog can not translate the html entity for a backslash.

$ kdialog --sorry 'foo<press Enter>
> oob'

What do you mean with this? I want to display a string like 'foo\noob', i.e. the path 'C:\program files\notepad'

bug 148575 means that \n is _not_ translated to a newline, this is the other way around: \n cannot be escaped, therefore it is not possible to have the _string_ \n inside a dialog _without_ being translated to a newline. Any \n inside a string _is_ translated into a newline.

sorry for the double post, it seems bugs.kde.org has some network/database troubles or my network connection is very bad :-(
