python-3.x - 如何知道用户是否在 wxPyhton 中更改了 AuiNotebook 的选项卡顺序？

Question

我在 wxPyhton 中使用AuiNotebook来处理不同选项卡上的信息。用户可以在选项卡中填写信息，通过拖放更改它们的顺序，然后生成一个总结选项卡中信息的句子。问题是当用户更改选项卡的顺序时，必须重新生成这句话，因为选项卡中的信息是依赖于顺序的（当顺序改变时含义也会改变）。

因此，我必须知道用户何时更改选项卡的顺序以重新生成句子。

我已经尝试捕获EVT_AUINOTEBOOK_END_DRAG和EVT_AUINOTEBOOK_DRAG_DONE事件，但仅在用户拆分选项卡时才调用它们。它们在我的情况下没有用。

这是我尝试执行此操作的代码：

from wx.aui import AuiNotebook, EVT_AUINOTEBOOK_PAGE_CLOSED
from wx.lib.dialogs import ScrolledMessageDialog
from event import event_handler
import wx
import shlex, subprocess


class CommandNoteBook(Panel):

    def __init__(self, parent, cmd, template_file, interface_file):
        super(Panel, self).__init__(parent)
        self.command = cmd
        self.notebook = AuiNotebook(self)
        #Refresh when info inside tab changes
        self.Bind(event_handler.EVT_VALUE_CHANGED, self.OnRefresh, id=wx.ID_ANY)
        #Refresh when a tab is closed
        self.Bind(EVT_AUINOTEBOOK_PAGE_CLOSED, self.OnRefresh, self.notebook)
        #Refresh when tabs order change
        self.Bind(EVT_AUINOTEBOOK_END_DRAG, self.OnRefresh, self.notebook)

您可以bind到wx.aui.EVT_AUINOTEBOOK_END_DRAG事件并在那里设置一个变量。

import wx
import wx.aui

class Frame1 (wx.Frame):
    def __init__(self,parent):
        wx.Frame.__init__ (self,parent,id=wx.ID_ANY,title="Aui Notebook",size=(500,300))

        self.tabs_altered = False

        bSizer1 = wx.BoxSizer( wx.VERTICAL )

        self.m_auinotebook1 = wx.aui.AuiNotebook( self, wx.ID_ANY)
        self.m_panel2 = wx.Panel( self.m_auinotebook1, wx.ID_ANY, style=wx.TAB_TRAVERSAL )
        self.p2_text = wx.StaticText(self.m_panel2, -1, "1 has not been moved", pos=(10,10))
        self.m_auinotebook1.AddPage( self.m_panel2, u"page1", True, wx.NullBitmap )
        self.m_panel3 = wx.Panel( self.m_auinotebook1, wx.ID_ANY, style=wx.TAB_TRAVERSAL )
        self.p3_text = wx.StaticText(self.m_panel3, -1, "2 has not been moved", pos=(10,10))
        self.m_auinotebook1.AddPage( self.m_panel3, u"page2", False, wx.NullBitmap )
        self.m_panel4 = wx.Panel( self.m_auinotebook1, wx.ID_ANY, style=wx.TAB_TRAVERSAL )
        self.p4_text = wx.StaticText(self.m_panel4, -1, "3 has not been moved", pos=(10,10))
        self.m_auinotebook1.AddPage( self.m_panel4, u"page3", False, wx.NullBitmap )
        bSizer1.Add( self.m_auinotebook1, 1, wx.EXPAND |wx.ALL, 5 )
        self.SetSizer( bSizer1 )
        self.Layout()
        self.Centre( wx.BOTH )

        # Connect Event
        self.m_auinotebook1.Bind(wx.aui.EVT_AUINOTEBOOK_END_DRAG, self.OnAuiDragend)

    def OnAuiDragend(self,event):
        page_idx = event.GetSelection()
        text = self.m_auinotebook1.GetPageText(page_idx)
        if text == "page1":
            self.p2_text.SetLabel("1 Moved")
        if text == "page2":
            self.p3_text.SetLabel("2 Moved")
        if text == "page3":
            self.p4_text.SetLabel("3 Moved")
        self.tabs_altered = True

if __name__ == "__main__":
    app = wx.App()
    frame = Frame1(None)
    frame.Show()
    app.MainLoop()
