Question

这是我到目前为止创建的表格。

这是我希望它看起来像是合并的列。

我想将昨天和今天的列合并为三列。所以昨天将高于股票，波动率和现金。然后同样为今天。我找到了一个名为wx.grid.SetColSize(self, int col, int width)的函数，但它没有任何效果。有谁知道怎么做？

这也是我的代码。

class MyForm(wx.Frame):
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, parent=None, title="Strategies' Allocations")
        self.panel = wx.Panel(self)

        button_refresh = wx.Button(self.panel, id=wx.ID_ANY, label='Refresh')
        button_refresh.Bind(wx.EVT_BUTTON, self.refresh)

        self.myGrid1 = gridlib.Grid(self.panel)
        self.myGrid1.CreateGrid(2, 6)

        self.myGrid1.SetRowLabelSize(60)
        self.myGrid1.SetRowLabelValue(0, "")
        self.myGrid1.SetRowLabelValue(1, "ABRVXX")

        for i in range(6):
            self.myGrid1.SetColSize(i, 60)

        self.myGrid1.SetColLabelValue(0, "")

Answer 1

这不会特别简单，但我认为你应该通过定义一个派生自wxGridCellAttrProvider的类并覆盖其GetColumnHeaderRenderer()方法来返回一个＆＃34;什么也不做＃34; wxGridColumnHeaderRenderer用于要合并的列，标准渲染器（由基类GetColumnHeaderRenderer()返回）用于其他列。然后，您只需要在表对象上使用自定义属性提供程序对象调用SetAttrProvider()。

快速而肮脏的方法是转储列标签SetColLabelSize(0)并将标题添加为单元格然后仅针对具有SetCellSize()的细胞调整细胞跨度下面我改变了myGrid1，但没有改变myGrid2。

Answer 3

在wxPython演示中查看GridLabelRenderer示例。它是基于wx.lib.mixins.gridlabelrenderer中的类为网格行和列绘制自定义标签的示例。使用这些类，您可以轻松地绘制标签。您只需要覆盖相应的Draw方法。

Answer 4

正如@RobinDunn所建议的，这是一个使用GridLabelRenderer的版本（种类），它不像它第一眼看上去那么复杂。
然而它确实有一两个怪癖请注意使用l和r来存储rect.left和rect.right。
它是以这种方式完成的，因为如果您调整rect.left，right.right也会调整，而不会让您进行调整。
我认为这是因为rect有一个大小，所以如果你调整1个元素，另一个补偿另请注意，您必须声明空白列标题，否则它们将恢复为标准＆＃34; A，B，C，D .....＆＃34;序列

您使用wx.Grid提到了您的问题，但是对于不需要此问题的人，可以使用wx.GridBagSizer。它允许项目跨越多个列和/或行。

使用python的wx.grid，如何合并列？
