当我将鼠标光标放在 wxPython 列表框上时如何显示列表菜单

Question

我制作了一个包含可用串行 com 端口的 wxPython 列表框。

我的例子是这样的

import wx

class MainFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, parent = None, title= "ListBox Test", size = (300,200))
        self.panel = wx.Panel(self)
        self.listBox1 = wx.ListBox(self.panel, -1, name='listBox1', pos =(50, 20), size= (100, 20), choices = ["Com 1", "Com 2", "Com 3", "Com 4"])

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

当我将鼠标光标放在列表框上时，我想将整个 com 端口列表显示到 select 个 com 端口。

谁能告诉我怎么做？

我建议 ComboBox 或 Choice

import wx

class MainFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, parent = None, title= "ListBox Test", size = (600,200))
        self.panel = wx.Panel(self)
        self.listBox1 = wx.ComboBox(self.panel, -1, pos =(50, 20), size= (100, 30), choices = ["Com 1", "Com 2", "Com 3", "Com 4"])
        self.listBox1.SetSelection(0)

        self.choice1 = wx.Choice(self.panel, -1, pos =(250, 20), size= (100, 30), choices = ["Com 1", "Com 2", "Com 3", "Com 4"])
        self.choice1.SetSelection(0)

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