[Libreoffice] [PATCH] fix for fdo#34768 - no update preview

[Péter Rabi]

Hi all,

I wrote a simple patch for resolving the following bug:

https://bugs.freedesktop.org/show_bug.cgi?id=34768
(the patch is attached therein)

When selecting a template in dialogue "Load Slide Design" in Impress,
the preview didn't get updated. I linked the already existing event
handler and called it also when selecting a region.

I would like to ask to apply the patch not only on master, but also on
branches -3-3 and -3-4, as the changes are hazard-free IMHO.

Best regards,
  Péter
