KTemporaryFile::createLocalFile()

[Dominik Haumann]

Hi,

QTemporaryFile has static functions
  QTemporaryFile * createLocalFile ( QFile & file )
  QTemporaryFile * createLocalFile ( const QString & fileName )

We have the following scenario in Kate:
 1. somehow get a (temporary) file that is not deleted
 2. run a diff programm and write the data to this file
 3. call KRun::runUrl() to open kompare to show the diff
 4. as kompare has the option X-KDE-HasTempFileOption it will remove
    the file on application exit

The code to solve (1) right now looks like this:

  KTemporaryFile tmpfile;
  tmpfile.setAutoRemove(false);
  tmpfile.open();
  QString fileName = tmpfile.fileName();
  tmpfile.close();

K/QTemporaryFile does not provide this functionality directly, the attached patch adds 
  QString KTemporaryFile::createLocalFile()
with the above implementation.

Do we want that / ok to commit?
If so, do I have to wait for a monday or what are the terms right now?

Dominik
