python之pyqt单选框与复选框

1、单选框

QRadioButton()

设置默认选择

.setChecked(True)

状态捕捉

.toggled.connect()

'''

#布局相关

layout = QHBoxLayout()
window.setLayout(layout)
#单选框
rb_man = QRadioButton('男')
rb_woman = QRadioButton('女')
#设置默认选择
rb_man.setChecked(True)
layout.addWidget(rb_man)
layout.addWidget(rb_woman)
window.show()
#状态捕获
rb_man.toggled.connect(man_toggled)
rb_woman.toggled.connect(woman_toggled)

'''

2、设置需要用到的函数的内容

'''

def man_toggled(checked):

   print("接收到 男 变化: {}".format(checked))
def woman_toggled(checked):
   print("接收到 女 变化: {}".format(checked))

'''

#多选框
lb = QLabel("爱好")

layout.addWidget(lb)
layout.addWidget(ck1)
layout.addWidget(ck2)
layout.addWidget(ck3)
layout.addWidget(ck4)
window.show()
#checkbox的信号
ck1.stateChanged.connect(ck1_state_changed)
ck2.stateChanged.connect(ck2_state_changed)
ck3.stateChanged.connect(ck3_state_changed)
ck4.stateChanged.connect(ck4_state_changed)

'''

5、设置需要用到的函数的内容

'''

def ck1_state_changed(state):

   if state == 2:
       print("ck1 changed")

def ck2_state_changed(state):

def ck3_state_changed(state):
   if state == 2:
       print("ck3 changed")
   else:
       print("ck3 取消选中")
