如何使auiManager任意调整大小并重新排列/排序窗格？

Question

我试图熟悉auiManager。我需要一个带有图表的窗格列表，这些图表可以自由调整并重新排列和任意。我使用auiPaneInfo类的Row（）和Position（）方法来设置新窗格的位置。那么，问题是，是否有任何方法可以使它在两个方向上重新调整？另外，有没有办法交换窗格或重新排列窗格的位置？如果没有，如何实施呢？

示例如下（按添加菜单项添加图表）：

import wx
import re, math, random
import wx.lib.agw.aui as aui
from wx.lib.colourdb import getColourList
class ChartPanel(wx.Panel):
    #----------------------------------------------------------------------
    def __init__(self, parent,color="lightgrey"):
        """"""
        wx.Panel.__init__(self, parent)
        self._color=color
        self.SetBackgroundColour(self._color)




########################################################################
class ChartFrame(wx.Frame):
    """
    Frame that holds all other widgets
    """

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""        
        wx.Frame.__init__(self, None, wx.ID_ANY, 
                        "Chart window: AUI manager",
                        size=(1200,600))
        self._winmgr=aui.AuiManager(agwFlags=aui.AUI_MGR_DEFAULT | aui.AUI_MGR_LIVE_RESIZE)
        self._winmgr.SetManagedWindow(self)
        self._charts={}
        self._n=0
        self._r=-1
        self._c=0

        menuBar = wx.MenuBar()
        chartMenu = wx.Menu()
        addMenuItem = chartMenu.Append(wx.NewId(), "Add", "Add new chart")
        menuBar.Append(chartMenu, "&Chart")
        self.Bind(wx.EVT_MENU, self.onChartAdd, addMenuItem)
        self.SetMenuBar(menuBar)

        self._winmgr.Update()
        self.Centre()
        self.Show()


    def onChartAdd(self, event):
        self._n = self._n + 1
        if self._r == 3:
            self._r = 0
            self._c = self._c + 1
        else:
            self._r = self._r + 1
        print "r= "+str(self._r)+" c= "+str(self._c)
        p = ChartPanel(self,random.choice(getColourList()))                
        self._charts['p%i'%self._n]=p
        self._winmgr.AddPane(
                self._charts['p%i'%self._n],
                aui.AuiPaneInfo().Caption('Chart %i'%self._n).Center().Position(self._r).Row(self._c).\
                CloseButton(True).MinimizeButton(True).MaximizeButton(True).PinButton(True).\
                BestSize((345, 400))
        )
        self._winmgr.Update()
