.. currentmodule:: PySide6.QtUiTools .. _loadUiType: loadUiType *********** .. py:function:: loadUiType(uifile: str) -> tuple(object, object) :param str uifile: The name of the `.ui` file :return: tuple(object, object) This function generates and loads a `.ui` file at runtime, and it returns a `tuple` containing the reference to the Python class, and the base class. We recommend not to use this approach as the workflow should be to generate a Python file from the `.ui` file, and then import and load it to use it, but we do understand that there are some corner cases when such functionality is required. The internal process relies on `uic` being in the PATH. The `pyside6-uic` wrapper uses a shipped `uic` that is located in the `site-packages/PySide6/uic`, so PATH needs to be updated to use that if there is no `uic` in the system. A simple use case is:: from PySide6.QtUiTools import loadUiType generated_class, base_class = loadUiType("themewidget.ui") # the values will be: # (, ) widget = base_class() form = generated_class() form.setupUi(widget) # form.a_widget_member.a_method_of_member() widget.show()
