Hi bojin_someone1
1) There is a widget with a large size in the window, which covers the area, thus making it impossible to add.
2）When you customize adding size in the window after selecting and clicking the widget, you may perform other operations during the process, such as clicking other widgets, etc., which will trigger other operations and lead to adding failure.
3) The size exceeds the window view, the widget supports negative coordinates but needs to be placed in the window view during the adding process.
