Glib-GIO-ERROR ** :系统上未安装GSettings模式

{
GtkWidget *dialog;
//dialog=gtk_file_chooser_dialog_new("Save it",GTK_WINDOW(gtk_builder_get_object(builder,"mainwindow")),GTK_FILE_CHOOSER_ACTION_SAVE,GTK_STOCK_OK,GTK_RESPONSE_OK,GTK_STOCK_CANCEL,GTK_RESPONSE_CANCEL);
//dialog=GTK_FILE_CHOOSER_DIALOG(gtk_builder_get_object(builder,"filechooserdialog"));
gtk_widget_show_all(dialog);
gint resp=gtk_dialog_run(GTK_DIALOG(dialog));
if(resp==GTK_RESPONSE_OK)
g_print("%s\n",gtk_file_chooser_get_filename(GTK_FILE_CHOOSER(dialog)));
}

推荐答案

尝试打开FileChooserDialog时，我遇到了同样的错误.

I got the very same error when trying to open a FileChooserDialog.

    (lancer_ihm.py:1047004): GLib-GIO-CRITICAL **: g_settings_schema_source_lookup: assertion 'source != NULL' failed

    (lancer_ihm.py:1047004): GLib-GIO-ERROR **: No GSettings schemas are installed on the system

我在Linux上使用python3运行Gtk3接口. Gtk3及其所有依赖项都是从源代码安装的.

I 'm running a Gtk3 interface with python3 on Linux. Gtk3 and all its dependencies were installed from the sources.

我只是将XDG_DATA_DIRS变量设置为gtk模式文件所在的路径，并且它可以工作.

I just set XDG_DATA_DIRS variable with the path to where the gtk schema files are located and it works.

    $ ls /home/user1/ctcils/dusserm/applications/gtk/3.12.1/share/glib-2.0/schemas/
    gschemas.compiled         org.gtk.exampleapp.gschema.xml             org.gtk.Settings.FileChooser.gschema.xml
    org.gtk.Demo.gschema.xml  org.gtk.Settings.ColorChooser.gschema.xml

    $ export XDG_DATA_DIRS=/Produits/publics/x86_64.Linux.RH6/glib/2.40.0/share/:/home/user1/ctcils/dusserm/applications/gtk/3.12.1/share/
