gtkRcResetStyles: gtkRcResetStyles
Description
This function recomputes the styles for all widgets that use a
particular GtkSettings object. (There is one GtkSettings object
per GdkScreen, see gtkSettingsGetForScreen); It is useful
when some global parameter has changed that affects the appearance
of all widgets, because when a widget gets a new style, it will
both redraw and recompute any cached information about its
appearance. As an example, it is used when the default font size
set by the operating system changes. Note that this function
doesn't affect widgets that have a style set explicitely on them
with gtkWidgetSetStyle.Usage
gtkRcResetStyles(settings)
