I have a table without vertical and horizontal headers
import sys
from PyQt5.QtCore import QAbstractTableModel, Qt
from PyQt5.QtWidgets import QApplication, QMainWindow, QTableView
class Model(QAbstractTableModel):
def __init__(self, data):
super().__init__()
self._data = data
def rowCount(self, index):
# The length of the outer list.
return len(self._data)
def columnCount(self, index):
# The following takes the first sub-list, and returns
# the length (only works if all rows are an equal length)
return len(self._data[0])
def data(self, index, role=Qt.DisplayRole):
if index.isValid():
if role == Qt.ItemDataRole.DisplayRole or role == Qt.ItemDataRole.EditRole:
value = self._data[index.row()][index.column()]
return str(value)
def setData(self, index, value, role):
if role == Qt.ItemDataRole.EditRole:
self._data[index.row()][index.column()] = value
return True
return False
def flags(self, index):
return Qt.ItemFlag.ItemIsSelectable | Qt.ItemFlag.ItemIsEnabled | Qt.ItemFlag.ItemIsEditable
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.table = QTableView()
data = [
[1, 9, 2],
[1, 0, -1],
[3, 5, 2],
[3, 3, 2],
[5, 8, 9],
]
self.model = Model(data)
self.table.setModel(self.model)
self.table.horizontalHeader().setVisible(False)
self.table.verticalHeader().setVisible(False)
self.setCentralWidget(self.table)
app = QApplication(sys.argv)
window = MainWindow()
window.show()
app.exec_()
When the table has a header, you can easily change the width of the columns by dragging But this cannot be done without a header
what i want is: Allow the user to resize the width of the column and the height of the row by holding the edge of the columns and rows and dragging the mouse.
