当我试图从.ui
文件中引用自定义类时,出现了这个错误。我做错了什么?
"QFormBuilder was unable to create a custom widget of the class 'TimelinePane'; defaulting to base class 'QWidget'."
QWidget
弹出了我在.ui
文件中指定的布局。问题只是自定义类。
为了添加自定义类的描述,我手动修改了.ui
文件(添加了整个<customwidgets>
部分),这就是为什么我必须开一个新问题,因为我还没有找到相同的问题。我怀疑在.ui
文件中类的路径,但我尝试的选项都不起作用(请参见我注释的部分)。我还猜测使用python
应该不是这里的问题,但并不完全确定。还没有尝试过C ++
。
