<h2>Detailed Description</h2>
<p>\class KTemporaryFile ktemporaryfile.h <KTemporaryFile>
</p>
<p>
A QTemporaryFile that will save in the KDE temp directory.
</p>
<p>
This class derives from QTemporaryFile and makes sure that your temporary
files go in the temporary directory defined by KDE. (This is retrieved by
using KStandardDirs to locate the "tmp" resource.) In general, whenever you
would use a QTemporaryFile() use a KTemporaryFile() instead.
</p>
<p>
By default the filename will start with your application's instance name,
followed by six random characters and an extension of ".tmp". You can use
setPrefix() and setSuffix() to change the beginning and ending of the random
name, as well as change the directory if you wish (read the descriptions of
these functions for more information). For complex specifications, you may
be better off calling QTemporaryFile.setFileTemplate() directly.
</p>
<p>
For example, let's make a new temporary file:
</p>
<p>
<pre class="fragment">
KTemporaryFile temp;
</pre>
</p>
<p>
This temporary file will currently be stored in the default KDE temporary
directory and have an extension of ".tmp". Now, let's change the directory:
</p>
<p>
<pre class="fragment">
temp.setPrefix("/var/lib/foodata/");
</pre>
</p>
<p>
Now the temporary file will be stored in "/var/lib/foodata" instead of the
default KDE temporary directory, with an extension of ".tmp". It's important
to remember the leading and trailing slashes to properly define the path!
Next, let's change the suffix to a particular extension:
</p>
<p>
<pre class="fragment">
temp.setSuffix(".pdf");
</pre>
</p>
<p>
Now the temporary file will be stored in "/var/lib/foodata" and have an
extension of ".pdf" instead of ".tmp".
</p>
<p>
Once you are done determining the name of the file, call open() to
create the file.
</p>
<p>
<pre class="fragment">
if ( !temp.open() ) {
// handle error...
}
</pre>
</p>
<p>
If open() is unable to create the file it will return false. If the call to
open() returns true you are ready to use your temporary file. If you don't
want the file removed automatically when the KTemporaryFile object is
destroyed, you need to call setAutoRemove(false), but make sure you have a
good reason for leaving your temp files around.

<div class="memdoc"><p>Sets a prefix to use when creating the file.
</p>
<p>
This function sets a prefix to use when creating the file. The random
part of the filename will come after this prefix. The prefix can also
change or modify the target directory. If <b>prefix</b> is an absolute
path it will override the default temporary directory. If <b>prefix</b> is
a relative directory it will be relative to the default temporary
location. To set a relative directory for the current working directory
you should use QTemporaryFile.setFileTemplate() directly.

end the prefix with a '/' if you are designating a directory.
