c++ - 如何在 QTreeWidget header 中添加按钮或其他小部件？

Question

谁能给我一些关于如何在 QTreeWidget 的标题中放置按钮的提示 一个最小的例子非常受欢迎？

Answer 1

对于评论中的人(以及基本上任何可能会因此得到帮助的人)，这里是下面代码的翻译 python 版本:

from PySide2 import QtWidgets, QtCore

import sys



class Header(QtWidgets.QHeaderView):
    def __init__(self, orientation, parent=None):
        super(Header, self).__init__(orientation, parent)

        self.button = QtWidgets.QPushButton('Button text', self)



class TreeWidget(QtWidgets.QTreeWidget):
    def __init__(self, parent=None):
        super(TreeWidget, self).__init__(parent)

        item0 = QtWidgets.QTreeWidgetItem(["Item 0"])
        item1 = QtWidgets.QTreeWidgetItem(["Item 1"])

        self.addTopLevelItem(item0)
        self.addTopLevelItem(item1)
        self.createHeader()

    def createHeader(self):
        header = Header(QtCore.Qt.Horizontal, self)
        self.setHeader(header)



if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)

    w = TreeWidget()
    w.show()
    sys.exit(app.exec_())


#QTreeWidget header is an "stand alone" widget - QHeaderView, so you can set the custom implementation of it.
