PyQt5复选框中的破折号不是✓当我设置CheckState（True）时

Question

As The pic shows, a dash line in checkbox not a tick. And I have to click to make it a tick, how can I fix it?

...
group_list = QListWidget(self)
for i in range(2):
    group = QListWidgetItem(str(i))
    group.setCheckState(1)
    group_list.addItem(group)       
...

ps: PyQt5.9.2

Answer 1

I find it out, Just setCheckState explicity

from PyQt5.QtCore import Qt
...
group.setCheckState(Qt.Checked)
....
