如何删除 GTK 条目（文本框）边框？

How to remove GTK entry (textbox) border?

我希望完全没有边界。我尝试了以下代码：

     GtkCssProvider *provider = gtk_css_provider_new ();
gtk_css_provider_load_from_data (GTK_CSS_PROVIDER (provider), 
"entry, .entry, GtkEntry { border-width:0px ; }", 
-1, NULL); 

GdkDisplay *display = gdk_display_get_default ();
GdkScreen *screen = gdk_display_get_default_screen (display);
gtk_style_context_add_provider_for_screen (screen, GTK_STYLE_PROVIDER     
         (provider), GTK_STYLE_PROVIDER_PRIORITY_APPLICATION);

我用 entry { border:none }

修复了它
