我需要在pyqt中写一个树？它看起来像这样:
Clients(this is text)
Type A (this is a Clients child and has a checkbox)
Type B (this is a Clients child and has a checkbox)
Vendors(this is text)
Mary (this is a Vendors child and has a checkbox)
Arnold (this is a Vendors child and has a checkbox)
Time Period
Init(this is a Time Period child, and would be a calendarWidget for date selection)
End (this is a Time Period child, and would be a calendarWidget for date selection) …
