addProvider
Adds a style provider to @context, to be used in style construction.
Note that a style provider added by this function only affects the style of the widget to which @context belongs. If you want to affect the style of all widgets, use func@Gtk.StyleContext.add_provider_for_display.
Note: If both priorities are the same, a GtkStyleProvider added through this function takes precedence over another added through func@Gtk.StyleContext.add_provider_for_display.
Parameters
provider
a GtkStyleProvider
priority
the priority of the style provider. The lower it is, the earlier it will be used in the style construction. Typically this will be in the range between %GTK_STYLE_PROVIDER_PRIORITY_FALLBACK and %GTK_STYLE_PROVIDER_PRIORITY_USER
