PyQGIS -能在Qt设计中推广我自己的课程吗？

Question

当我开发QGIS插件时，我在Qt中推广类时遇到了一些问题。

我使用插件生成器创建插件，然后将结构重新组织如下：

结构

所以现在，当我将Qt设计器中的ComboBox提升到src文件夹中的combobox时。在QGIS中，我得到了错误信息。

我在Qt Designer中提升的小部件如下所示：

Qt提升Widget

也许有人知道怎么写代码来修复呢？有可能吗？我想提一下，当我在QGIS之外开发一些程序时，我还没有遇到这个问题。

这是QGIS插件的源代码。

test_dockwidget.py

import os

from qgis.PyQt import QtGui, QtWidgets, uic
from qgis.PyQt.QtCore import pyqtSignal

FORM_CLASS, _ = uic.loadUiType(os.path.join(
os.path.dirname(__file__), r'ui\test_dockwidget_base.ui'))


class testDockWidget(QtWidgets.QDockWidget, FORM_CLASS):

closingPlugin = pyqtSignal()

    def __init__(self, parent=None):
        """Constructor."""
        super(testDockWidget, self).__init__(parent)
        # Set up the user interface from Designer.
        # After setupUI you can access any designer object by doing
        # self.<objectname>, and you can use autoconnect slots - see
        # http://doc.qt.io/qt-5/designer-using-a-ui-file.html
        # #widgets-and-dialogs-with-auto-connect
        self.setupUi(self)

    def closeEvent(self, event):
        self.closingPlugin.emit()
        event.accept()

combobox.py

from PyQt5.QtWidgets import QComboBox

class Combobox(QComboBox):
    def __init__(self, parent):
        super().__init__()
        self.setParent(parent)
        self.currentIndexChanged.connect(self.color)

    def color(self):
        print(self.sender(), self.currentIndex())

当然还有test.py文件，但是它太长了，它是由插件生成器创建的，所以我不把它粘贴在这里。

没有经过测试，但我要说，在src目录中创建一个空文件src将解决src无法将src识别为模块的问题。
