Python 使用QT设计器访问GUI的输入（组合框、旋转框、水平滑块）

我试着让这个代码尽可能清晰。我使用QT设计器获得了代码的基本内容

共有3个主要部分-访问输入（125-129）、设置按钮命令（41-45）和定义操作（155-168）（简化-打印输入）

目前的问题是，它在使用GUI时没有输出正确的值

例如，当您更改水平滑块，然后按下按钮时，它只打印“1”，即使它应该上升到“8”

我相信部分问题与“重译”有关，但我无法准确指出

### I tried to make this code as clear as possible. I got the bare-bones of the code using QT Designer
### There are 3 main parts - accessing inputs (125-129), setting a command to the button (41-45), and defining the actions(155-168)(to simplify - print the inputs)
### The problem with it as it stands, is that it doesn't output the correct value when using the GUI 
### For instance, when you change the horizontalSlider then press the button, it only prints "1", even though it should go up to "8"
### I believe part of the problem has something to do with the "retranslateUi", but I cannot pinpoint it...

如果你能帮上忙，那就太好了。这是一个正在进行的项目，我正试图将其转化为一种学习体验。到目前为止我很喜欢，但我还有很多东西要学。。谢谢大家!

希望这就是你想要的。我目前仍在学习python，但我相信您的函数试图访问一个类变量，但您没有正确调用该变量。即使将变量设置为全局变量，它们对于类范围也是全局的。我将函数移动到类中，对它们进行了一些调整，以便在调用函数时捕获comboBox、spinBox和horizontalSlider的值
