如何判断checkBox是否被激活?

  • 772

如何确定CheckBox激活了什么?

比方说,如果它checkBox处于活动状态,则显示 1,如果它未处于活动状态,则显示 2。

怎么做?如果小部件上有“勾号”,我认为是活动的。

с = #определение состояния
if c == #есть "галочка":
   x = 5
elif c == #нет "галочки":
   x = 10
print(x)

#что-то не так

    永远不要修改在 QT Designer 中创建的模块

    selectBooks该方法 class Main向左移动了 4 个位置。
