在Linux上使用范围创建wxSlider [英] Creating wxSlider with range on Linux

问题描述

我正在尝试使用Python中的wxSlider创建一个带有范围选择选项的滑块.它具有可选的range参数，但问题是:

I'm trying to create a slider with option for range selection using wxSlider in Python. It has an optional range parameter but the problem is:

SL_SELRANGE:允许用户在滑块上选择一个范围.仅限Windows.

SL_SELRANGE: Allows the user to select a range on the slider. Windows only.

我正在使用Linux. 我以为我可以继承wxSlider并使它在Linux上运行，或者自己创建一个自定义窗口小部件.问题是我不确定该如何选择. 任何想法/指针/指向正确方向的想法都会受到赞赏.

And I'm using Linux. I thought I might subclass wxSlider and make it work on Linux, or create a custom widget on my own. The problem is I'm not sure how to go about either option. Any ideas/pointers/pointing me in the right direction would be appreciated.

我尝试过类似的事情:

range_slider = wx.Slider(parent, wx.ID_ANY, 0, 0, 100, style=wx.SL_HORIZONTAL | wx.SL_LABELS | wx.SL_SELRANGE)

但是"SL_SELRANGE"在Linux上什么也不做(应该提供两个句柄以选择范围).

but the "SL_SELRANGE" does nothing on Linux (should provide two handles, to select range).

推荐答案

您可以有两个滑块；一个会推高另一个，使它保持较低，而另一个会保持较高?

You could have two sliders; one that will push the other so it remains lower, and one will remain higher?

我知道这不是一回事，对不起，但这是一个选择. 因此，当self.minSlider移动时，将wx.EVT_SCROLL与一个函数绑定，该函数将执行以下操作:

I know it isn't the same thing, sorry, but it is an option. So when ever self.minSlider is moved, you bind wx.EVT_SCROLL with a function that will do something like:

self.minSlider.Bind(wx.EVT_SCROLL, self.respondSliderChange())

def respondSliderChange(self):
    if self.minSlider.GetValue() >= self.maxSlider.GetValue():
        self.maxSlider.SetValue(self.minSlider.GetValue()+1)

，对于maxSlider，反之亦然.

and vice-versa for the maxSlider.

除此之外，您还可以在此处中创建一个自定义窗口小部件.

Besides that, you can look into creating a custom widget here.
