Class wxpython通过单击按钮打开新窗口，将参数传递给新窗口

晚上好/早上好

我目前正在制作一个包含许多按钮的GUI，其中一些（9）按钮打开了一个新窗口。此窗口在设置中的所有9种情况下都是相同的，但当用户继续时，此窗口的更改取决于单击了哪些按钮。因此，我想制作一个按钮处理程序，处理所有9个按钮并生成一个新窗口，但将参数传递给新窗口。这是我的代码：

# Handles the creation of all of the buttons
def make_button(text, callback, starty, startx, height, width):
    button = wx.Button(self, -1, text)
    sizer.Add(button, (starty, startx), (height, width), wx.EXPAND)
    button.Bind(wx.EVT_BUTTON, callback)
    return button

make_button("Configure", lambda event: self.RailConfig_clicked(event, 1, 1), 10, 1, 1 ,1)
make_button("Configure", lambda event: self.RailConfig_clicked(event, 1, 2), 10, 2, 1 ,1)
make_button("Configure", lambda event: self.RailConfig_clicked(event, 1, 3), 10, 3, 1 ,1)

make_button("Configure", lambda event: self.RailConfig_clicked(event, 2, 1), 10, 6, 1 ,1)
make_button("Configure", lambda event: self.RailConfig_clicked(event, 2, 2), 10, 7, 1 ,1)
make_button("Configure", lambda event: self.RailConfig_clicked(event, 2, 3), 10, 8, 1 ,1)

make_button("Configure", lambda event: self.RailConfig_clicked(event, 3, 1), 10, 11, 1 ,1)
make_button("Configure", lambda event: self.RailConfig_clicked(event, 3, 2), 10, 12, 1 ,1)
make_button("Configure", lambda event: self.RailConfig_clicked(event, 3, 3), 10, 13, 1 ,1)

make_button("Configure", lambda event: self.RailConfig_clicked(event, 4, 1), 10, 16, 1 ,1)
make_button("Configure", lambda event: self.RailConfig_clicked(event, 4, 2), 10, 17, 1 ,1)
make_button("Configure", lambda event: self.RailConfig_clicked(event, 4, 3), 10, 18, 1 ,1)

def RailConfig_clicked(self, event, slot, rail):
    self.Rail1ConfigSlot1_window = NewWindow(parent=None, id= -1)
    self.Rail1ConfigSlot1_window.Show()
    print slot
    print rail

class NewWindow(wx.Frame):
    def __init__(self,parent,id):
        wx.Frame.__init__(self, parent, id, 'New Window')
        wx.Frame.CenterOnScreen(self)
        self.initialize()

    def initialize(self):
        sizer = wx.GridBagSizer()

        self.VoltageLabel = wx.StaticText(self, -1, 'Margin High Voltage', wx.DefaultPosition, wx.DefaultSize)
        sizer.Add(self.VoltageLabel, (0,0), (1,1))

        self.VoltageLabel2 = wx.StaticText(self, -1, 'Margin Low Voltage', wx.DefaultPosition, wx.DefaultSize)
        sizer.Add(self.VoltageLabel2, (3,0), (1,1))

        self.VoltageLabel3 = wx.StaticText(self, -1, 'Current Voltage Low Value', wx.DefaultPosition, wx.DefaultSize)
        sizer.Add(self.VoltageLabel3, (0,2), (1,1))

        self.VoltageLabel4 = wx.StaticText(self, -1, 'Current Voltage High Value', wx.DefaultPosition, wx.DefaultSize)
        sizer.Add(self.VoltageLabel4, (3,2), (1,1))

        self.SetSizerAndFit(sizer)
        self.SetSizeHints(-1,-1)
        self.SetAutoLayout(True)
        self.Show(True)
        for col in range(0,5):
                sizer.AddGrowableCol(col)

        self.editlow = wx.TextCtrl(self, -1, "", wx.DefaultPosition, wx.DefaultSize)
        sizer.Add(self.editlow, (1,0), (1,1), wx.EXPAND)

        self.submitlow = wx.Button(self, label="Submit")
        sizer.Add(self.submitlow, (5, 5), (1, 1), wx.EXPAND)

因此，您可以看到，我使用lambda事件调用将两个参数传递给RailConfig_单击的def，slot和rail。在RailConfig_单击的内部，我创建了一个新窗口，但我想再次将这些变量传递给该新窗口，以便我可以使用这些信息来决定以后要更改什么

我尝试将参数放入NewWindow，如下所示：

self.Rail1ConfigSlot1_window = NewWindow(parent=None, id= -1, slot, rail)

但我得到：

SyntaxError: non-keyword arg after keyword arg

我想建议一种不同的方法来创建按钮和处理按钮点击事件。希望有帮助：

# -*- coding: utf-8 -*-

class MyFrame1 ( wx.Frame ):

    def __init__( self, parent ):
        wx.Frame.__init__ ( self, parent, id = wx.ID_ANY, title = "Button group demo", pos = wx.DefaultPosition, size = wx.Size( 300,200 ), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL )

        self.m_panel1 = wx.Panel( self, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.TAB_TRAVERSAL )
        gSizer1 = wx.GridSizer( 3, 3, 0, 0 )
        # Loop to add (9) buttons
        Btn = lambda x: wx.Button( self.m_panel1, wx.ID_ANY, u"Configure", wx.DefaultPosition, wx.DefaultSize, 0, name = u"row:%d col:%d" % (math.ceil((x -1)/3) + 1, (x - 1)%3 + 1) )
        for i in range(1, 10):
            btn = Btn(i)
            gSizer1.Add( btn, 0, wx.ALIGN_CENTER|wx.ALL, 5 )
            btn.Bind( wx.EVT_BUTTON, self.OnButtonClicked )         

        self.m_panel1.SetSizer( gSizer1 )
        self.m_panel1.Layout()
        gSizer1.Fit( self)  
        self.Centre( wx.BOTH )
        self.Show() 

    # Button click event handler
    def OnButtonClicked( self, event ):
        name = event.GetEventObject().GetName()
        # Here you can make a new window, and pass in parameters
        wx.MessageBox('In %s' % (name), 'Button Clicked')
        event.Skip()

if __name__ == '__main__':
    app = wx.App(False)
    frame = MyFrame1(None)
    app.MainLoop()

你能把你的全部源代码都贴出来吗？在self.Rail1ConfigSlot1\u window=NewWindow（parent=None，id=-1，slot，rail）中，您传递了四个参数，但是NewWindow类只需要两个参数（parent和id），所以您得到了SyntaxEror。有趣的是，我发布了另一个问题，问我为什么创建多个按钮的for循环不起作用。虽然这不是这个问题的答案，但我会尝试一下，看看我是否能让这部分发挥作用。我明天会通知你的，谢谢。
