单击按钮时如何更改 wxpython gizmo LED 颜色

Question

我想在单击 wx 按钮时更改 wx gizmos led 的颜色。

我的例子如下

import wx
import wx.lib.gizmos.ledctrl as led

class Main(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, parent = None, title ="LED test")
        panel = wx.Panel(self)
        self.myLED = led.LEDNumberCtrl(panel, -1, pos = (150,50), size = (100,100))
        self.myLED.SetBackgroundColour("gray")
        self.myButton = wx.Button(panel, -1,  "myButton", pos =(50, 50))
        self.myButton.Bind(wx.EVT_BUTTON, self.changeLEDColor)

    def changeLEDColor(self,event):
        self.myLED.SetBackgroundColour("green")


if __name__ == "__main__":
    app = wx.App()
    frame = Main()
    frame.Show()
    app.MainLoop()

当我点击 'mybutton' 时，我预计 LED 颜色会变为 'green'，但它仍然是 'gray'。

我的示例有什么问题？

添加self.Refresh()或self.myLED.Refresh()将触发重绘。这是 link 到 docs. If it flickers, look into wx.Frame.SetDoubleBuffered(True) - docs
