绑定到wxButton的wxPython弹出窗口

我一直在四处浏览,浏览了许多不同的站点,但是我找不到如何在wxPython中为wxButton创建弹出窗口的方法.

有什么想法吗？

解决方法:

您看过wxPython演示了吗？它有几个使用wx.PopupWindow及其变体的示例.这是一个基于演示的示例：

import wx

########################################################################
class TestPopup(wx.PopupWindow):
    """"""

    #----------------------------------------------------------------------
    def __init__(self, parent, style):
        """Constructor"""
        wx.PopupWindow.__init__(self, parent, style)

        panel = wx.Panel(self)
        self.panel = panel
        panel.SetBackgroundColour("CADET BLUE")

        st = wx.StaticText(panel, -1,
                           "This is a special kind of top level\n"
                           "window that can be used for\n"
                           "popup menus, combobox popups\n"
                           "and such.\n\n"
                           "Try positioning the demo near\n"
                           "the bottom of the screen and \n"
                           "hit the button again.\n\n"
                           "In this demo this window can\n"
                           "be dragged with the left button\n"
                           "and closed with the right."
                           ,
                           pos=(10,10))
        sz = st.GetBestSize()
        self.SetSize( (sz.width+20, sz.height+20) )
        panel.SetSize( (sz.width+20, sz.height+20) )

        panel.Bind(wx.EVT_LEFT_DOWN, self.OnMouseLeftDown)

        panel.Bind(wx.EVT_RIGHT_UP, self.OnRightUp)

        st.Bind(wx.EVT_LEFT_DOWN, self.OnMouseLeftDown)
        st.Bind(wx.EVT_MOTION, self.OnMouseMotion)
        st.Bind(wx.EVT_LEFT_UP, self.OnMouseLeftUp)
        st.Bind(wx.EVT_RIGHT_UP, self.OnRightUp)

        wx.CallAfter(self.Refresh)    

    def onm ouseLeftDown(self, evt):
        self.Refresh()
        self.ldPos = evt.GetEventObject().ClientToScreen(evt.GetPosition())

        self.panel.CaptureMouse()

    def onm ouseMotion(self, evt):

            nPos = (self.wPos.x + (dPos.x - self.ldPos.x),
                    self.wPos.y + (dPos.y - self.ldPos.y))
            self.Move(nPos)

    def onm ouseLeftUp(self, evt):
        if self.panel.HasCapture():
            self.panel.ReleaseMouse()

    def OnRightUp(self, evt):
        self.Show(False)
        self.Destroy()
