当我尝试从参考我的自定义类我得到这个错误.ui
文件。 这有什么错我做什么?
"QFormBuilder was unable to create a custom widget of the class 'TimelinePane'; defaulting to base class 'QWidget'."
QWidget
弹出用我指定布局.ui
文件。 问题就是自定义类。
添加自定义类的描述,我修改.ui
手动文件(加入整个<customwidgets>
部分),这就是为什么我要打开一个新的问题,因为我还没有找到相同的Q尚未。 我怀疑在类路径.ui
文件,但没有我想的选项(见我注释掉的部分)的工作。 我还猜想,使用python
不应该在这里的事情,但我不能完全肯定。 没有尝试过C++
呢。
