GridBagSizer : wxPython:有关Python布局管理的帮助

Question

我在尝试调整控件的大小时遇到了问题，谁能指出哪里需要对整齐的控件堆叠进行更正？

即TextCtrl框应该是标准的默认大小。

而Read & Set按钮就堆叠在TextCtrl框的正下方。

下面是我的代码：

class AVMCPanel(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent, -1)

        #create the grouping box and sizer for the outline
        self.box = wx.StaticBox(self, -1, "AVMC CONTROL PANEL")
        self.bsizer = wx.StaticBoxSizer(self.box, wx.VERTICAL)

        #create the sizer and place controls within box
        self.gbs = wx.GridBagSizer(5,5)

        self.sampleList = ['zero', 'one', 'two', 'three', 'four'] #temp list items
        self.t1 = wx.StaticText(self, label="Power Rail to margin:")
        self.lb1 = wx.ListBox(self, 1, (100, 50), (150, 120), self.sampleList, wx.LB_SINGLE)
        self.t2 = wx.StaticText(self, label="Read Voltage:")
        self.t3 = wx.StaticText(self, label="Set Voltage:")
        self.read_btn = wx.Button(self, 1, "  Read  ", (-1,-1) )
        self.set_btn = wx.Button(self, 1, "  Set  ", (-1,-1))
        self.rtext = wx.TextCtrl(self, 1, "", size=(80, -1), style=wx.ALL)
        self.stext = wx.TextCtrl(self, 1, "", size=(80, -1), style=wx.ALL)

        self.gbs.Add(self.t1, (0,0))
        self.gbs.Add(self.lb1, (1,0))
        self.gbs.Add(self.t2, (0,5))
        self.gbs.Add(self.t3, (0,10))
        self.gbs.Add(self.read_btn, (2,5))
        self.gbs.Add(self.set_btn, (2,10))
        self.gbs.Add(self.rtext, (1,5))
        self.gbs.Add(self.stext, (1,10))


        #Place the control inside group box
        self.bsizer.Add(self.gbs, 0, flag=wx.ALL, border=5)

        #Place the static group box sizer within the border frame
        #Creating a border that the static box will sit inside
        self.border = wx.BoxSizer()
        self.border.Add(self.bsizer, 1000, wx.ALL, 10)
        self.SetSizer(self.border)

谢谢。

在以下代码中：

self.rtext = wx.TextCtrl(self, 1, "", size=(80, -1), style=wx.ALL)
self.stext = wx.TextCtrl(self, 1, "", size=(80, -1), style=wx.ALL)

您正在TextCtrl上使用Sizer标志。删除此选项可防止TextCtrl垂直变高。

您的按钮正在向下移动，因为ListBox正在加宽其上方的行。使用以下命令使ListBox跨越两行：

self.gbs.Add(self.lb1, (1,0), span=wx.GBSpan(2,1))
