The names of the widgets are defined in the `.ui` file. This `.ui` file `must` be loaded into an attribute called `self.form` so that it is loaded into the task panel correctly. In this class all widgets are automatically created as `self.form.`. The `.ui` file may use special FreeCAD widgets such as `Gui::InputField` (based on `QLineEdit`) and `Gui::QuantitySpinBox` (based on `QAbstractSpinBox`). See the Doxygen documentation of the corresponding files in `src/Gui/`, for example, `InputField.h` and `QuantitySpinBox.h`. Attributes ---------- source_command: gui_base.GuiCommandBase This attribute holds a reference to the calling class of this task panel. This parent class, which is derived from `gui_base.GuiCommandBase`, is responsible for calling this task panel, for installing certain callbacks, and for removing them. It also delays the execution of the internal creation commands by using the `draftutils.todo.ToDo` class.
