V-Scroll table

Ver 1

Source, they say use MVC, QListView/QTableView, delegates

class QMainWindows():
  QScrollArea(self) sa:
    QFrame(sa) f:
      QVBoxLayout(f) l:
        l.addWidget(QLabel(self)

Ver 2:

Source; they say use QListView.QStyledItemDelegate

QWidget:
  QVboxLayout:
    QScrollArea:
      QHBoxLayout[]:
        (QWidget, QWidget)

Ver 3:

Teh best

QMainWindows():
  QVScrollArea():
    QWidget():
      QVboxLayout():
        QLabel()[]

MVC:

• QItemDelegate - for edit only (view <> model)
• QStyledItemDelegate -

RTFM2:

• 5 QTableView+QStandardItemModel+QItemDelegate - 2020, tutorial
• 4 QTableView+QStyledItemDelegate.paint() - 2020, short tutorial
• 4 QTableView+QItemDelegate - 2022, QA
• 2 QTableWidget.setCellWidget() - 2012, hints, now works
• 4 ↳ QTableWidget.setCellWidget() - 2010, "don't add wigets to QTableWidget(); use delegate"
• 2 QTableWidget.setCellWidget() or +QItemDelegate - 2016, hints, непонятно
• 2 QListView+QStyleItemDelegate.paint() - 2017, low-level gfx
• 3 QTableWidget+xDelegate - 2015, editable, работает, но выглядит кривенько
• 3 QTableView+QStandardItemModel+QStyledItemDelegate - 2020, hints
• 2 etc: 2012, hint

Итак:

1. ☒ QTableView + QAbstractTableModel + QStyledItemDelegate + openPersistentEditor(idx) - феерическая хрень (delegate для edit прежде всего)
2. ☐ QTableView.setIndexWidget()
3. ☑ QTableWidget.setCellWidget():

• hide table headers
• Expand rows to content (set row size + resize inner) | content to row (layout?)
  • remove chart.axes
  • chart.setMargins(QMargins(0, 0, 0, 0)) # def 4x20
  • chart.layout().setContentsMargins(0, 0, 0, 0) # def 4x6.0
