There is an interface in which the table is drawn as QTableView. In api, associated with the program, there is some data that is loaded and form a certain number of columns, rows, and so on in the program itself. Tell me, please, how can I make changes to the table cells, because I cannot just “click”, as in the case of a table with fields that were originally drawn and other things, I cannot, that is, the program simply does not allow me to do this.

Thanks for attention!

upd: Here is the class that forms the table, here I need a function that allows you to make changes to the cells. (tasks loaded from another class, there requests and so on):

class TableModel(QAbstractTableModel): def __init__(self, parent=None): super(TableModel, self).__init__(parent) self.tasks = [] def rowCount(self, parent=None, *args, **kwargs): return len(self.tasks) def columnCount(self, parent=None, *args, **kwargs): return 7 def data(self, index, role=None): if role == Qt.DisplayRole: row = index.row() column = index.column() if column == 0: return self.tasks[row].title elif column == 1: return self.tasks[row].start_date.toString() elif column == 2: return self.tasks[row].end_date.toString() elif column == 3: return self.tasks[row].man_hours elif column == 4: return self.tasks[row].task_type elif column == 5: return self.tasks[row].done return None def headerData(self, section, orientation, role=None): if role == QtCore.Qt.DisplayRole: if orientation == QtCore.Qt.Horizontal: return ["Задача", "Дата начала", "Дата конца", "Отдел", "Количество человек", "Трудоёмкость", "Выполнение"][section]

You need to override the setData method. Try the example below:

 import sys from PyQt5 import QtCore, QtGui, QtWidgets from PyQt5.QtGui import * from PyQt5.QtCore import * from PyQt5.QtWidgets import * class TableModel(QAbstractTableModel): def __init__(self, tasks, parent=None): # +++ super(TableModel, self).__init__(parent) self.tasks = tasks # +++ def rowCount(self, parent=None, *args, **kwargs): return len(self.tasks) def columnCount(self, parent=None, *args, **kwargs): return 7 def data(self, index, role=None): if role == Qt.DisplayRole: row = index.row() column = index.column() if column == 0: return self.tasks[row]#.title elif column == 1: return self.tasks[row]#.start_date.toString() elif column == 2: return self.tasks[row]#.end_date.toString() elif column == 3: return self.tasks[row]#.man_hours elif column == 4: return self.tasks[row]#.task_type elif column == 5: return self.tasks[row]#.done return None def headerData(self, section, orientation, role=None): if role == QtCore.Qt.DisplayRole: if orientation == QtCore.Qt.Horizontal: return ["Задача", "Дата начала", "Дата конца", "Отдел", "Количество человек", "Трудоёмкость", "Выполнение"][section] def setData(self, index, tasks, role): # <--- # +++ if role == Qt.EditRole: row = index.row() #column = index.column() self.tasks[row] = tasks[row] return True return False class MainWindow(QMainWindow): def __init__(self): super().__init__() tasks = ["1a","2a","3a","4a","5a","6a"] # Начальное заполнение self.model = TableModel(tasks) self.table = QTableView() self.table.verticalHeader().hide() self.table.setAlternatingRowColors(True) self.table.horizontalHeader().setSectionResizeMode(QHeaderView.Stretch) self.table.setModel(self.model) btn = QPushButton("Click me") btn.clicked.connect(self.btnClicked) centralWidget = QWidget() self.setCentralWidget(centralWidget) grid = QGridLayout(centralWidget) grid.addWidget(self.table, 0, 0) grid.addWidget(btn, 1, 0) def btnClicked(self): rows = self.model.rowCount() for row in range(rows): self.model.setData(self.model.index(row, 0), ["21a","22a","23a","24a","25a","26a"], # +++ Qt.EditRole) self.table.resizeColumnsToContents() if __name__ == '__main__': app = QApplication(sys.argv) mw = MainWindow() mw.show() mw.setGeometry(400, 100, 550, 300) sys.exit(app.exec_())

  • Hello, thank you! But the fact is that I need to make changes in the course of the program, and here, as I understand it, the initial filling is set. - rolkins
