如何从pyside中的滑块获取值? [英] How to get values from the slider in pyside?

问题描述

大家好，

我是 gui 和 qt 的新手，有点卡住了.我从这里下载了滑块示例 a> [qt.gitorious.org] 并将其调整为仅滑块.我现在得到的代码如下:http://pastebin.com/EkXxdPee

I’m a total newbi in general gui and qt, and am kind of stuck. I downloaded the slider example from here [qt.gitorious.org] and sobered it down to just the sliders. The code I’ve got right now is as follows: http://pastebin.com/EkXxdPee

我现在想从滑块中读取值并对其进行处理(使用 zeromq 将其发送到另一个程序).我想我必须对 valueChanged 做一些事情，但我不知道是什么.有人可以帮我一点吗?

I now want to read the values from the slider and do stuff with it (send it over to another program using zeromq). I guess I have to do something with valueChanged, but I have no clue what. Could anybody help me out a little bit?

欢迎所有提示！

感谢 Romha Korev 的回答和一些谷歌搜索，我在这里找到了一个完整的工作示例:http://zetcode.com/gui/pysidetutorial/widgets/

Thanks to the answer of Romha Korev and some googling I found a full working example here: http://zetcode.com/gui/pysidetutorial/widgets/

我只是从那里开始工作，现在我终于拥有了我想要的东西.谢谢！

I simply worked from there and I finally have what I want now. Thanks!

推荐答案

使用 value() 方法获取 QSlider 中的值.

Use the method value() to get the value in the QSlider.

slider = QtGui.QSlider()
slider.setValue( 5 )
print( slider.value() ) # Will print '5'
