工具欄呈現以下wxPython 2.9升級

Question

此代碼工作正常wxPython 2.8後，今天升級到2.9，但工具欄不顯示 顯示。如果我移除self.SetToolBar（）調用，圖標確實顯示，但不是按鈕，並且當重新調整屏幕大小時，工具欄格式不會拉伸。有任何想法嗎？

import wx 

class MyApp(wx.App): 
    def OnInit(self): 
     self.frame = Example(None, title="Word Bag", size=(400,100)) 
     self.SetTopWindow(self.frame) 
     self.frame.Show() 

     return True 


class MyToolbar(wx.ToolBar): 
    """Toolbars are attached to frames, so need TBar = Toolbar(self) in frame init""" 
    def __init__(self, parent): 
     wx.ToolBar.__init__(self, parent) 

     # set my preferred default size for icons 
     self.SetToolBitmapSize((32,32)) 

     # the main bit where icons are formatted, added, and bound to handlers 
     self.initialiseIcons() 

     # Need to call realise before exiting 
     self.Realize() 

    def initialiseIcons(self): 
     """Iterate over icons and add them to toolbar""" 
     for each in self.toolbarData(): 
      self.createSimpleTool(*each) 

    def createSimpleTool(self, label, filename, statbar, handler): 
     """Adds icons to bar using AddSimpleTool""" 
     if not label: 
      self.AddSeparator() 
      return 
     bmp = wx.Image(filename, wx.BITMAP_TYPE_PNG).ConvertToBitmap() 
     tool = self.AddSimpleTool(-1, bmp, label, statbar) 
     self.Bind(wx.EVT_MENU, handler, tool) 

    def toolbarData(self): 
     """Put your icon data here in the following format... 
     [0] = tooltip label, [1] = bitmap path, [2] = status bar label, [3] = bound function""" 
     return [["Add new word","/Users/paulpatterson/Desktop/add.png","Add a new word to the dictionary",self.OnAddWord]] 

    # toolbar icon handlers here... 
    def OnAddWord(self, event): 
     pass 

    def OnRemoveWord(self, event): 
     pass 

    def OnSearchWord(self, event): 
     pass 



class Example(wx.Frame): 

    def __init__(self, parent, title, size): 
     super(Example, self).__init__(parent, title=title, size=size) 

     # Create and set the toolbar 
     tBar = MyToolbar(self) 
     self.SetToolBar(tBar) 

     self.frameSizer = wx.BoxSizer(wx.VERTICAL) 

     self.panelOne = MyPanel(self) 



     self.frameSizer.Add(self.panelOne, 1, wx.EXPAND) 
     self.SetSizer(self.frameSizer) 
     #self.frameSizer.Fit(self) 

     self.Centre() 
     self.Show() 


class MyPanel(wx.Panel): 

    def __init__(self, parent): 
     super(MyPanel, self).__init__(parent) 

     self.mainSizer = wx.BoxSizer(wx.VERTICAL) 


     ### widgets here 


     # set optimum layout for mainsizer... 
     self.SetSizer(self.mainSizer) 
     # ...then fit main sizer to the panel. 
     self.mainSizer.Fit(self) 


if __name__ == '__main__': 

    app = MyApp(False) 
    app.MainLoop()

幾個小時前我有同樣的問題。我無法使用自定義創建的工具欄工作，但使用Frame.CreateToolBar()按預期工作。例如：

class MyFrame(wx.Frame): 
    def __init__(self): 
     wx.Frame.__init__(
      self, parent=None, id=-1, title='Test window', 
      size=wx.Size(800, 600) 
     ) 

     self.setup_toolbar() 

    def setup_toolbar(self): 
     # First create the toolbar. 
     self.toolbar = self.CreateToolBar(wx.TB_FLAT | wx.TB_TEXT) 
     self.Bind(wx.EVT_TOOL, self.on_toolbar) 

     # Add a 'Clear all' button. 
     self.toolbar.AddLabelTool(
      wx.ID_NEW, 'Clear all', get_toolbar_art('new_big'), 
      shortHelp='Remove all the contents from the text inputs.' 
     ) 

     # Add an 'Open' button. 
     self.toolbar.AddLabelTool(
      wx.ID_OPEN, 'From file...', get_toolbar_art('open_big'), 
      shortHelp='Fill the input box with the ' + 
         'contents of a Linjekort text file.' 
     ) 

     # self.toolbar.AddSeparator() # A separator. 

     # Add a 'Save all' button. 
     self.toolbar.AddLabelTool(
      wx.ID_SAVE, 'Save results to...', get_toolbar_art('save_big'), 
      shortHelp='Save all the Ozi files to a directory.' 
     ) 

     self.toolbar.Realize() 

def get_toolbar_art(name): 
    return wx.Bitmap('icons/{}.png'.format(name)) 

但是，這並不回答如何讓自定義工具欄的子類工作。您是否嘗試過使用sizer將工具欄添加到佈局中，而不是使用SetToolBar函數？這是我知道避免結束OSX本機Frame工具欄的唯一途徑。這裏是做了這樣一個例子：

def create_output_panel(self, parent, slug, label): 
    panel = wx.Panel(parent, style=wx.BORDER_THEME) 
    panel.SetBackgroundColour(
     wx.SystemSettings.GetColour(wx.SYS_COLOUR_3DSHADOW) 
    ) 

    # Toolbar. 
    toolbar = wx.ToolBar(panel, -1, style=wx.BORDER_RAISED) 
    toolbar.AddSimpleTool(
     wx.ID_SAVE, get_toolbar_art('save'), 
     shortHelpString='Save to file...' 
    ) 
    toolbar.Realize() 
    toolbar.Bind(wx.EVT_TOOL, lambda evt: print('Success')) 

    # Text control. 
    textctrl = wx.TextCtrl(
     panel, -1, style=wx.TE_READONLY | wx.TE_MULTILINE | wx.BORDER_NONE 
    ) 

    # Organize controls. 
    sizer = wx.BoxSizer(wx.VERTICAL) 
    sizer.Add(
     wx.StaticText(panel, -1, label), proportion=0, border=5, flag=wx.ALL 
    ) 
    sizer.Add(toolbar, proportion=0, flag=wx.EXPAND) 
    sizer.Add(textctrl, proportion=1, flag=wx.EXPAND) 

    panel.SetSizer(sizer) 
    return panel
