wx.Layout出于某种原因从面板上“删除”窗口小部件

Question

我正在尝试学习wxPython并遇到布局问题。我尝试将小部件集放在单独的面板中，以在将来管理它们的位置\大小。但是由于某些原因，对于“顶部块”面板工作正常的代码不适用于“ Mods”面板。

我用google（）搜索Layout（）函数，但是由于某些原因，它在“顶部块”和“模块”中的行为有所不同。无需重新排列小部件，只需将它们全部放在面板顶部的细线中即可。我无法发布图片，但可以提供屏幕截图。

class ItemInfo(wx.Frame):
    def __init__(self, parent, item, *args):
        super(ItemInfo, self).__init__(parent)
        self.Size = wx.Size(500, 600)

        self.current_item = self.find_current_item(item)
        common_item_types = Storage.ItemStorage.get_common_item_keys()

        # self.Bind(wx.EVT_SHOW, self.show_current_item_stats)
        mod_list = []
        mod_list.append("None")
        for key, value in Storage.item_storage.mod_dict.items():
            mod_list.append(key)

        # Главная панель
        main_panel = wx.Panel(self)
        main_panel.SetBackgroundColour('#484f49')

不应为sizer而不是面板调用Layout。但是，嘿，发布问题后如何找到答案很有趣+）
