wxPython在BoxSiz中显示网格

Question

我正在尝试显示一个网格以及一些按钮，以便在wx.面板使用wx.Boxsizer公司. 如果我先将按钮添加到BoxSizer中，按钮在垂直布局中位于网格的顶部，那么我可以使网格和按钮正确显示。如果我在垂直布局中切换网格在按钮顶部的顺序，按钮将不显示网格将占据整个面板。在

作品：

    self.sizer.AddSpacer(10)
    self.sizer.Add(self.bottomBtnsPnl,1,wx.EXPAND)
    self.sizer.AddSpacer(10)
    self.sizer.Add(self.gridPnl,1,wx.EXPAND)
    self.sizer.AddSpacer(10)

不起作用：

您可以使用wxPython Widget检查工具自诊断大多数视觉布局问题，您可以在这里阅读：

• http://wiki.wxpython.org/Widget%20Inspection%20Tool

这将有助于向您展示窗口小部件如何重叠，小部件的父级是什么，小部件的大小等等。我还注意到您正在设置self.gridPnl的ID设置为1。这很糟糕。小于100的id通常由wxPython保留，这就是为什么您通常会看到magic-1或wx.ID\u任何在示例apps online中。-1和wx.ID\u任何告诉wxPython动态创建一个不会与当前正在使用的任何其他ID冲突的ID。在

最后，下面是一个超级简单的示例，演示如何创建一个下面有几个按钮的网格：

import wx
import wx.grid as gridlib

########################################################################
class MyForm(wx.Frame):
    """"""

    #                                   
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, parent=None, title="A Simple Grid")
        panel = wx.Panel(self)

        myGrid = gridlib.Grid(panel)
        myGrid.CreateGrid(12, 8)

        btn_sizer = wx.BoxSizer(wx.HORIZONTAL)
        btn_one = wx.Button(panel, label="One")
        btn_sizer.Add(btn_one, 0, wx.CENTER|wx.ALL, 5)

        btn_two = wx.Button(panel, label="Two")
        btn_sizer.Add(btn_two, 0, wx.CENTER|wx.ALL, 5)

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(myGrid, 1, wx.EXPAND)
        sizer.Add(btn_sizer)
        panel.SetSizer(sizer)

if __name__ == "__main__":
    app = wx.App(False)
    frame = MyForm()
    frame.Show()
    app.MainLoop()
