lyx_mirror/src/frontends/qt4/GuiToolbar.cpp
Stefan Schimanski c81e3a0203 * use base color for layout list background. Qt docs say: 
QPalette::Base:	Used mostly as the background color for text
entry widgets, but can also be used for other painting - such as the
background of combobox drop down lists and toolbar handles. It is
usually white or another light color.
