wx.Panel 未在 wx.Python 中显示

如何解决wx.Panel 未在 wx.Python 中显示

我开始使用 wxpython 并且我正在尝试做一个小视频游戏，有点像俄罗斯方块。我正在尝试使用 GridGagSizer 中的面板显示块，但面板不显示。这是我的代码：

import wx

altura=12
class MenuFrame(wx.Frame):
    def __init__(self,*args,**kwds):
        # begin wxGlade: CalculatorFrame.__init__
        #kwds["style"] = kwds.get("style",0) | wx.DEFAULT_FRAME_STYLE
        wx.Frame.__init__(self,**kwds)
        self.SetSize((400,300))
        self.SetTitle("Deslizador")
        self.Center()

        self.half_sizer=wx.SplitterWindow(self,wx.ID_ANY)
        self.settings=wx.Panel(self.half_sizer)
        self.grid_side=wx.Panel(self.half_sizer)
        #self.grid_side.SetBackgroundColour("red")
        self.half_sizer.SetMinimumPanesize(130)
        #self.half_sizer.SetSashPosition(100)
        self.half_sizer.SplitVertically(self.settings,self.grid_side)

        self.options_separator=wx.BoxSizer(wx.VERTICAL)
        
        self.fichero_separator=wx.BoxSizer(wx.HORIZONTAL)

        self.label_fichero=wx.StaticText(self.settings,wx.ID_ANY,"Fichero: ")
        self.fichero_separator.Add(self.label_fichero,0)

        self.control_fichero=wx.TextCtrl(self.settings,wx.ID_ANY)
        self.fichero_separator.Add(self.control_fichero,1,wx.EXPAND)

        self.options_separator.Add(self.fichero_separator,wx.EXPAND)

        self.abr_fich=wx.Button(self.settings,"Abrir fichero")
        self.options_separator.Add(self.abr_fich,wx.EXPAND)

        self.nuev_part = wx.Button(self.settings,"Nueva partida")
        self.options_separator.Add(self.nuev_part,wx.EXPAND)

        self.sep_n_filas=wx.BoxSizer(wx.HORIZONTAL)

        self.label_n_filas=wx.StaticText(self.settings,"N° Filas:")
        self.sep_n_filas.Add(self.label_n_filas,wx.ALIGN_CENTER_VERTICAL)

        self.spin_n_filas = wx.SpinCtrl(self.settings,min=3,max=100,initial=12)
        self.sep_n_filas.Add(self.spin_n_filas,wx.EXPAND)

        self.options_separator.Add(self.sep_n_filas,wx.EXPAND)

        self.sep_jugadas=wx.BoxSizer(wx.HORIZONTAL)

        self.label_jugada = wx.StaticText(self.settings,"Jugada: ")
        self.sep_jugadas.Add(self.label_jugada,wx.ALIGN_CENTER_VERTICAL)

        self.control_jugada = wx.TextCtrl(self.settings,wx.ID_ANY)
        self.sep_jugadas.Add(self.control_jugada,wx.EXPAND)

        self.options_separator.Add(self.sep_jugadas,wx.EXPAND)


        self.label_lista = wx.StaticText(self.settings,"Lista de jugadas:")
        self.options_separator.Add(self.label_lista,0)

        self.lista = wx.ListBox(self.settings)
        self.options_separator.Add(self.lista,10,wx.EXPAND)

        font = wx.Font(20,family=wx.FONTFAMILY_MODERN,style=0,weight=90,underline=False,faceName="",encoding=wx.FONTENCODING_DEFAULT)
        self.label_puntos = wx.StaticText(self.settings,"PTOS: 0")
        self.label_puntos.SetFont(font)
        self.options_separator.Add(self.label_puntos,wx.CENTER)

        self.settings.SetSizer(self.options_separator)

        self.tabla=wx.GridBagSizer(5,5)
        panel_add = wx.Panel()
        # panel_add=wx.StaticText(parent.grid_side,"test")
        panel_add.SetBackgroundColour("red")
        self.tabla.Add(panel_add,wx.GBPosition(3,3),wx.GBSpan(1,flag=wx.EXPAND)
        print(self.tabla.FindItemAtPosition(wx.GBPosition(3,3)))
        self.draw_table([[3,3,"E",3]],self)


        self.grid_side.SetSizer(self.tabla)
        self.Layout()
    def draw_table(self,blocks,parent):
        for i in range(12):
            text_add = wx.StaticText(parent.grid_side,"abcdefghijklmopqrstuvwxyz"[i])
            parent.tabla.Add(text_add,wx.GBPosition(i,0),1))
        for i in range(10):
            text_add = wx.StaticText(parent.grid_side,str(i))
            parent.tabla.Add(text_add,wx.GBPosition(12,i),1))
        """for i in blocks:
            panel_add = wx.Panel()
            # panel_add=wx.StaticText(parent.grid_side,"test")
            panel_add.SetBackgroundColour("red")
            parent.tabla.Add(panel_add,wx.GBPosition(i[0],i[3]),flag=wx.EXPAND)
            print(i[0],i[3])"""
class MyApp(wx.App):
    def OnInit(self):
        self.frame = MenuFrame(None,"")
        self.SetTopWindow(self.frame)
        self.frame.Show()
        return True

if __name__ == "__main__":
    app = MyApp(0)
    app.MainLoop()

如果你运行它，你会注意到静态文本显示完美，但面板没有。我什至使用打印线来检查它是否正确添加到 GridBagSizer 中，是的，确实如此。 谁能帮我？ PS：这可能是我犯的一个非常愚蠢的错误，我是从 wxpython 开始的。

解决方法

我相信您的问题在这里：panel_add = wx.Panel()，它没有parent。
我怀疑以下内容将解决您当前的问题（我已将其重命名为 block 并将其定义为 block = wx.Panel(self.grid_side)）：

import wx

altura=12
class MenuFrame(wx.Frame):
    def __init__(self,*args,**kwds):
        # begin wxGlade: CalculatorFrame.__init__
        #kwds["style"] = kwds.get("style",0) | wx.DEFAULT_FRAME_STYLE
        wx.Frame.__init__(self,**kwds)
        self.SetSize((400,300))
        self.SetTitle("Deslizador")
        self.Center()

        self.half_sizer=wx.SplitterWindow(self,wx.ID_ANY)
        self.settings=wx.Panel(self.half_sizer)
        self.grid_side=wx.Panel(self.half_sizer)
        #self.grid_side.SetBackgroundColour("red")
        self.half_sizer.SetMinimumPaneSize(130)
        #self.half_sizer.SetSashPosition(100)
        self.half_sizer.SplitVertically(self.settings,self.grid_side)

        self.options_separator=wx.BoxSizer(wx.VERTICAL)
        
        self.fichero_separator=wx.BoxSizer(wx.HORIZONTAL)

        self.label_fichero=wx.StaticText(self.settings,wx.ID_ANY,"Fichero: ")
        self.fichero_separator.Add(self.label_fichero,0)

        self.control_fichero=wx.TextCtrl(self.settings,wx.ID_ANY)
        self.fichero_separator.Add(self.control_fichero,1,wx.EXPAND)

        self.options_separator.Add(self.fichero_separator,wx.EXPAND)

        self.abr_fich=wx.Button(self.settings,"Abrir fichero")
        self.options_separator.Add(self.abr_fich,wx.EXPAND)

        self.nuev_part = wx.Button(self.settings,"Nueva partida")
        self.options_separator.Add(self.nuev_part,wx.EXPAND)

        self.sep_n_filas=wx.BoxSizer(wx.HORIZONTAL)

        self.label_n_filas=wx.StaticText(self.settings,"N° Filas:")
        self.sep_n_filas.Add(self.label_n_filas,wx.ALIGN_CENTER_VERTICAL)

        self.spin_n_filas = wx.SpinCtrl(self.settings,min=3,max=100,initial=12)
        self.sep_n_filas.Add(self.spin_n_filas,wx.EXPAND)

        self.options_separator.Add(self.sep_n_filas,wx.EXPAND)

        self.sep_jugadas=wx.BoxSizer(wx.HORIZONTAL)

        self.label_jugada = wx.StaticText(self.settings,"Jugada: ")
        self.sep_jugadas.Add(self.label_jugada,wx.ALIGN_CENTER_VERTICAL)

        self.control_jugada = wx.TextCtrl(self.settings,wx.ID_ANY)
        self.sep_jugadas.Add(self.control_jugada,wx.EXPAND)

        self.options_separator.Add(self.sep_jugadas,wx.EXPAND)


        self.label_lista = wx.StaticText(self.settings,"Lista de jugadas:")
        self.options_separator.Add(self.label_lista,0)

        self.lista = wx.ListBox(self.settings)
        self.options_separator.Add(self.lista,10,wx.EXPAND)

        font = wx.Font(20,family=wx.FONTFAMILY_MODERN,style=0,weight=90,underline=False,faceName="",encoding=wx.FONTENCODING_DEFAULT)
        self.label_puntos = wx.StaticText(self.settings,"PTOS: 0")
        self.label_puntos.SetFont(font)
        self.options_separator.Add(self.label_puntos,wx.CENTER)

        self.settings.SetSizer(self.options_separator)

        self.tabla=wx.GridBagSizer(5,5)
 

        self.draw_table(self)
        self.draw_blocks([[3,3,"E",3]],self)
        self.draw_blocks([[4,self)
        self.draw_blocks([[1,8]],self)
        self.draw_blocks([[8,1]],2]],self)
        self.draw_blocks([[7,"A",5],[7,7],self)

        self.grid_side.SetSizer(self.tabla)
        self.Layout()
        self.Show()
 
    def draw_table(self,parent):
        for i in range(12):
            text_add = wx.StaticText(parent.grid_side,"abcdefghijklmopqrstuvwxyz"[i])
            parent.tabla.Add(text_add,wx.GBPosition(i,0),wx.GBSpan(1,1))
        for i in range(10):
            text_add = wx.StaticText(parent.grid_side,str(i))
            parent.tabla.Add(text_add,wx.GBPosition(12,i),1))

    def draw_blocks(self,blocks,parent):
        for i in blocks:
            block = wx.Panel(self.grid_side)
            block.SetBackgroundColour("red")
            parent.tabla.Add(block,wx.GBPosition(i[0],i[3]),flag=wx.EXPAND)


if __name__ == "__main__":
    app = wx.App()
    MenuFrame(None,"")
    app.MainLoop()

显然，这些块是随机测试。
