如何在QTreeWidget中创建子项目?
我已经能够创建顶级项目(如下所列),但仍在寻找子项目。
PyQt->5.6
Python->3.5
Spyder->3.0.2
import sys
from PyQt5.QtWidgets import QTreeWidget, QTreeWidgetItem, QApplication, QWidget
if __name__ == '__main__':
app = 0
if QApplication.instance() != None:
app = QApplication.instance()
else:
app = QApplication(sys.argv)
l1 = QTreeWidgetItem([ "String A", "String B", "String C" ])
l2 = QTreeWidgetItem([ "String AA", "String BB", "String CC" ])
w = QWidget()
w.resize(510,210)
tw = QTreeWidget(w)
tw.resize(500,200)
tw.setColumnCount(3)
tw.setHeaderLabels(["Column 1", "Column 2", "Column 3"])
tw.addTopLevelItem(l1)
tw.addTopLevelItem(l2)
w.show()
app.exec_()
