gtk_text_buffer_create_tag 创建警告：'GtkTextTag' 没有名为“\u0004”的属性

Question

当我打电话时

gtk_text_buffer_create_tag(buffer, "small_distance", "foreground", "green");

在我的程序中，它在运行时发出警告： g_object_set_is_valid_property: 对象 class 'GtkTextTag' 没有属性名为 '\u0004'

Answer 1

您必须 "NULL-terminate" 参数列表：

gtk_text_buffer_create_tag(buffer, "small_distance", 
                           "foreground", "green", 
                           NULL);

注意 NULL 为 "last parameter"。

参数列表被视为 g_object_set() 。它指出

value for the first property, followed optionally by more name/value pairs, followed by NULL

gtk_text_buffer_create_tag creates warning: 'GtkTextTag' has no property named '\u0004'
