This function does not act recursively. Setting the color of a
container does not affect its children. Note that some widgets that
you may not think of as containers, for instance gtk.Buttons,
are actually containers.
This API is mostly meant as a quick way for applications to
change a widget appearance. If you are developing a widgets
library and intend this change to be themeable, it is better
done by setting meaningful CSS classes in your
widget/container implementation through Style.contextAddClass.
This way, your widget library can install a gtk.CssProvider
with the GTK_STYLE_PROVIDER_PRIORITY_FALLBACK priority in order
to provide a default styling for those widgets that need so, and
this theming may fully overridden by the user’s theme.
Note that for complex widgets this may bring in undesired
results (such as uniform background color everywhere), in
these cases it is better to fully style such widgets through a
gtk.CssProvider with the GTK_STYLE_PROVIDER_PRIORITY_APPLICATION
priority.
Sets the color to use for a widget.
All other style values are left untouched.
