Gtk.Widget.prototype.modify_bg

function modify_bg(state:Gtk.StateType, color:Gdk.Color):void {
    // Gjs wrapper for gtk_widget_modify_bg()
}

Sets the background color for a widget in a particular state.

All other style values are left untouched. See also Gtk.modify_style.

<note><para> Note that "no window" widgets (which have the %GTK_NO_WINDOW flag set) draw on their parent container's window and thus may not draw any background themselves. This is the case for e.g. Gtk.Label. </para><para> To modify the background of such widgets, you have to set the background color on their parent; if you want to set the background of a rectangular area around a label, try placing the label in a Gtk.EventBox widget and setting the background color on that. </para></note>
