Question

我希望从上到下（即垂直）在QTableView显示文本中制作水平标题单元格，我该怎么做？

示例PyQt5应用程序，它显示一个QTableView，其水平标题显示正常方向的文本：

from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
import sys

class TableModel(QAbstractTableModel):
    def __init__(self, parent):
        super(TableModel, self).__init__(parent)

    def headerData(self, section, orientation, role):
        if orientation != Qt.Horizontal:
            return
        if role != Qt.DisplayRole:
            return

        return 'Header Data'

    def data(self, index, role):
        if role != Qt.DisplayRole:
            return

        return 'Row Data'

    def rowCount(self, parent):
        return 1

    def columnCount(self, parent):
        return 1


class Window(QMainWindow):
    def __init__(self):
        super(Window, self).__init__()

        main_widget = QWidget(self)
        self.setCentralWidget(main_widget)
        layout = QVBoxLayout(main_widget)

        view = QTableView(main_widget)
        view.horizontalHeader().setVisible(True)
        view.verticalHeader().setVisible(False)
        layout.addWidget(view)
        model = TableModel(view)
        view.setModel(model)
        view.resizeColumnsToContents()

app = QApplication(sys.argv)
window = Window()
window.show()
app.exec_()

Answer 1

简单use of delegate will not work here。

您需要继承QHeaderView并覆盖paintSection 在实施它时，您需要：

旋转和翻译画家
计算新的矩形，它将在转换之上进行重新计算
使用新值调用paintSection的旧实现
恢复画家状态（逆向转换）。

简单的解决方案是在标题单元格的文本中的每个字符之间插入换行符（请参阅模型＆＃39; headerData方法）：

from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
import sys

class TableModel(QAbstractTableModel):
    def __init__(self, parent):
        super(TableModel, self).__init__(parent)

    def headerData(self, section, orientation, role):
        if orientation != Qt.Horizontal:
            return
        if role != Qt.DisplayRole:
            return

        # Make text appear flowing downwards
        return '\n'.join([x for x in 'Header Data']).replace(' ', '')

    def data(self, index, role):
        if role != Qt.DisplayRole:
            return

        return 'Row Data'

    def rowCount(self, parent):
        return 1

    def columnCount(self, parent):
        return 1


class Window(QMainWindow):
    def __init__(self):
        super(Window, self).__init__()

        main_widget = QWidget(self)
        self.setCentralWidget(main_widget)
        layout = QVBoxLayout(main_widget)

        view = QTableView(main_widget)
        view.horizontalHeader().setVisible(True)
        view.verticalHeader().setVisible(False)
        layout.addWidget(view)
        model = TableModel(view)
        view.setModel(model)
        view.resizeColumnsToContents()

app = QApplication(sys.argv)
window = Window()
window.show()
app.exec_()

在QTableView中，如何使水平标题单元格显示垂直文本？
