It takes about 28 seconds to create 1000 "features" - 7000 QTextEdits. It only takes about 3.5 seconds if i replace the QTextEdit's with simple QWidgets.
I would suggest avoiding so many QTextEdits. You could use QLineEdits if you don't need multiple lines, or avoid using widgets for the view by using a QTreeView/QTreeWidget and have custom editting widgets when the user double clicks to edit a row. Also your hide/show functions are redundant. If you hide a qt widget all of it's children are hidden automatically, and will reappear when you show the widget. If you construct a widget with children and call show on it, all the children are automatically shown.
