WxPython.如何关闭单元格编辑器

Question

如何实现在失去焦点时关闭自己的单元格编辑器？由于内置的wx编辑器可以工作。

现在，只有当您在网格中选择另一个单元格时，我的编辑器才会关闭。例如，如果您单击按钮，单元格编辑器(0，1(就会关闭，而不仅仅是当您单击另一个单元格时。

我的编辑器和渲染器：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import wx
import wx.grid

class GridCellColourEditor(wx.grid.GridCellEditor):
def __init__(self):
super().__init__()
def Create(self, parent, id, evtHandler):
self._cp = wx.ColourPickerCtrl(parent, id)
self.SetControl(self._cp)
if evtHandler:
self._cp.PushEventHandler(evtHandler)
def BeginEdit(self, row, col, grid):
self.startValue = grid.GetTable().GetValue(row, col)
self._cp.SetColour(self.startValue)
self._cp.SetFocus()
def EndEdit(self, row, col, grid, oldval):
val = self._cp.GetColour().GetAsString(wx.C2S_HTML_SYNTAX)
if val != oldval:
return val
else:
return None
def ApplyEdit(self, row, col, grid):
val = self._cp.GetColour().GetAsString(wx.C2S_HTML_SYNTAX)
grid.GetTable().SetValue(row, col, val)
def Reset(self):
self._cp.SetColour(self.startValue)
def Clone(self):
return GridCellColourEditor()
class GridCellColourRenderer(wx.grid.GridCellRenderer):
def __init__(self):
super().__init__()
def Draw(self, grid, attr, dc, rect, row, col, isSelected):
if grid.IsEnabled():
bgColour = grid.GetDefaultCellBackgroundColour()
else:
bgColour = grid.GetBackgroundColour()
dc.SetBrush(wx.Brush(bgColour, wx.SOLID))
dc.SetPen(wx.TRANSPARENT_PEN)
dc.DrawRectangle(rect)
colour = grid.GetTable().GetValue(row, col)
x = rect.x + 3
y = rect.y + 3
width = rect.width - 6
height = rect.height - 6
dc.SetBrush(wx.Brush(colour, wx.SOLID))
dc.SetPen(wx.Pen(wx.BLACK))
dc.DrawRoundedRectangle(x, y, width, height, 3)
def GetBestSize(self, grid, attr, dc, row, col):
return attr.GetSize()
def Clone(self):
return GridCellColourRenderer()
class Frame(wx.Frame):
def __init__(self):
super().__init__(None)
vbox = wx.BoxSizer(wx.VERTICAL)
self.grid = wx.grid.Grid(self, size=(100, 50))
vbox.Add(self.grid, flag=wx.EXPAND)
self.grid.CreateGrid(1, 2)
self.grid.SetCellEditor(0, 0, GridCellColourEditor())
self.grid.SetCellRenderer(0, 0, GridCellColourRenderer())
self.grid.SetCellEditor(0, 1, wx.grid.GridCellTextEditor())
self.grid.SetCellRenderer(0, 1, wx.grid.GridCellStringRenderer())
btn = wx.Button(self, -1, 'For kill focus')
vbox.Add(btn, 0, wx.ALL, 10)
self.SetSizer(vbox)
app = wx.App()
frame = Frame()
frame.Show()
app.MainLoop()

为什么，如果wx。TextCtrl用作wx。控件，然后在失去焦点时成功关闭单元格编辑器。如果你用wx。ColourPickerCtrl，编辑器不关闭？
