我正在使用PyQt5和PyCharm。如何将一列下的所有单元格对齐到中心?下面的代码似乎可以正常工作,但仅适用于作为标头的一个单元格。我应该更改或添加什么?
item3 = QtWidgets.QTableWidgetItem('Item Name')
item3.setTextAlignment(QtCore.Qt.AlignHCenter|QtCore.Qt.AlignVCenter)
self.tableWidget.setHorizontalHeaderItem(2, item3)
答案 0 :(得分:1)
建立列对齐的一种简单方法是通过委托:
import sys
from PyQt5 import QtCore, QtWidgets
class AlignDelegate(QtWidgets.QStyledItemDelegate):
def initStyleOption(self, option, index):
super(AlignDelegate, self).initStyleOption(option, index)
option.displayAlignment = QtCore.Qt.AlignCenter
class MainWindow(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.tableWidget = QtWidgets.QTableWidget(15, 6)
self.setCentralWidget(self.tableWidget)
for i in range(self.tableWidget.rowCount()):
for j in range(self.tableWidget.columnCount()):
it = QtWidgets.QTableWidgetItem("{}-{}".format(i, j))
self.tableWidget.setItem(i, j, it)
delegate = AlignDelegate(self.tableWidget)
self.tableWidget.setItemDelegateForColumn(2, delegate)
# for all columns:
# self.tableWidget.setItemDelegate(delegate)
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.resize(640, 480)
w.show()
sys.exit(app.exec_())
