From 74c1d61aa3547c80e1c7ee05397c76ccd6260fa7 Mon Sep 17 00:00:00 2001 From: Peter Penz Date: Tue, 3 Nov 2009 21:48:27 +0000 Subject: Since Qt 4.5 it is possible to have translucient windows. The tooltip approach having a delegate and custom drawing + animation code for transparent tooltips has now been replaced by a translucient window where any kind of (animated) widget can be embedded. Still a lot of finetuning has to be done, but maybe this code can be part of kdelibs in KDE 4.5 (systemsettings currently used the Dolphin tooltips code). Additionally the tooltip uses now KMetaDataWidget instead of using KMetaInfo. This assures that no blocking of the application will occur even if there is a buggy Strigi analyzer that ignores the maximum size-setting and might block the retrieving of the meta data.
