如何订阅wxpython phoenix treeListCtrl将鼠标双击

使用wxpython4（又称凤凰城），我想要带有treelistCtrl的GUI来订阅双击并告诉处理程序代码TreelistCtrl中的单元格是双击的。

。。。

我目前正在使用的WXPYTHON4的特定版本是4.0.0b2，它带有一个可用的演示代码软件包：包括下面的TreelistCtrl演示的代码。

我应该如何修改此代码，以便我可以在TreelistCtrl上双击？

#!/usr/bin/env python
import wx
import wx.dataview
import images
#----------------------------------------------------------------------
class TestPanel(wx.Panel):
    def __init__(self, parent, log):
        self.log = log
        wx.Panel.__init__(self, parent, -1)
        self.Bind(wx.EVT_SIZE, self.OnSize)
        self.tree = wx.dataview.TreeListCtrl(self, -1, style =
                                        wx.TR_DEFAULT_STYLE

                                   )
        isz = (16,16)
        il = wx.ImageList(isz[0], isz[1])
        fldridx     = il.Add(wx.ArtProvider.GetBitmap(wx.ART_FOLDER,      wx.ART_OTHER, isz))
        fldropenidx = il.Add(wx.ArtProvider.GetBitmap(wx.ART_FILE_OPEN,   wx.ART_OTHER, isz))
        fileidx     = il.Add(wx.ArtProvider.GetBitmap(wx.ART_NORMAL_FILE, wx.ART_OTHER, isz))
        smileidx    = il.Add(images.Smiles.GetBitmap())
        self.tree.SetImageList(il)
        self.il = il
        # create some columns
        self.tree.AppendColumn("Main column")
        self.tree.AppendColumn("Column 1")
        self.tree.AppendColumn("Column 2")
        ##self.tree.SetMainColumn(0) # the one with the tree in it...
        self.tree.SetColumnWidth(0, 175)
        self.root = self.tree.InsertItem(self.tree.GetRootItem(), wx.dataview.TLI_FIRST, "The Root Item")
        self.tree.SetItemText(self.root, 1, "col 1 root")
        self.tree.SetItemText(self.root, 2, "col 2 root")
        self.tree.SetItemImage(self.root, closed=fldridx, opened=fldropenidx)

        for x in range(15):
            txt = "Item %d" % x
            child = self.tree.AppendItem(self.root, txt)
            self.tree.SetItemText(child, 1, txt + "(c1)")
            self.tree.SetItemText(child, 2, txt + "(c2)")
            self.tree.SetItemImage(child, closed=fldridx, opened=fldropenidx)
            for y in range(5):
                txt = "item %d-%s" % (x, chr(ord("a")+y))
                last = self.tree.AppendItem(child, txt)
                self.tree.SetItemText(last, 1, txt + "(c1)")
                self.tree.SetItemText(last, 2, txt + "(c2)")
                self.tree.SetItemImage(last, closed=fldridx, opened=fldropenidx)
                for z in range(5):
                    txt = "item %d-%s-%d" % (x, chr(ord("a")+y), z)
                    item = self.tree.AppendItem(last,  txt)
                    self.tree.SetItemText(item, 1, txt + "(c1)")
                    self.tree.SetItemText(item, 2, txt + "(c2)")
                    #TODO: Phoenix change selected to smiley
                    self.tree.SetItemImage(item, closed=fileidx, opened=smileidx)
                    ## self.tree.SetItemImage(item, fileidx, which = wx.TreeItemIcon_Normal)
                    ## self.tree.SetItemImage(item, smileidx, which = wx.TreeItemIcon_Selected)

        self.tree.Expand(self.root)
        ## self.tree.GetMainWindow().Bind(wx.EVT_RIGHT_UP, self.OnRightUp)
        self.tree.Bind(wx.EVT_TREE_ITEM_ACTIVATED, self.OnActivate)

    def OnActivate(self, event):
        self.log.write('OnActivate: %s' % self.tree.GetItemText(event.GetItem()))
    def OnRightUp(self, event):
        pos = event.GetPosition()
        item, flags, col = self.tree.HitTest(pos)
        if item:
            self.log.write('Flags: %s, Col:%s, Text: %s' %
                           (flags, col, self.tree.GetItemText(item, col)))
    def OnSize(self, event):
        self.tree.SetSize(self.GetSize())

我在面板构造函数的末端尝试了以下两个变体，其中两个都没有工作：

变体1：

...
    self.tree.Bind(wx.EVT_TREE_ITEM_ACTIVATED, self.OnActivate)
    self.tree.Bind(wx.EVT_LEFT_DCLICK, self.OnLeftDClick)
def OnLeftDClick(self, event):
    print("LeftDClick")
def OnActivate(self, event):
...

变体2：

...
    self.tree.Bind(wx.EVT_TREE_ITEM_ACTIVATED, self.OnActivate)
    self.Bind(wx.EVT_LEFT_DCLICK, self.OnLeftDClick)
def OnLeftDClick(self, event):
    print("LeftDClick")
def OnActivate(self, event):
...

当我双击树中的某个地方时，我希望看到"左键"文本出现在控制台上，但不是。

注1：我以前在WXPYTHON3中使用该功能，通过订阅如下：

self.tree.GetMainWindow().Bind(wx.EVT_LEFT_DCLICK, self.OnLeftDClick)

该代码在wxpython4中不再起作用：

AttributeError: 'TreeListCtrl' object has no attribute 'GetMainWindow'

注2：我要专门为wxpython4做这项工作的原因是我要从python2移植到python3，而wxpython3与python3不相容。

。

注3：WXPYTHON4.0.0B2 TREELISTCTRL在C 代码中带有以下错误：http：//trac.wxwidgets.org/ticket/17476。该错误归档的补丁为我解决了问题。

self.tree.bind（wx.evt_tree_item_activated，self.onactivate） -> self.tree.bind（wx.dataview.evt_treelist_treelist_item_item_item_activated，self.onactivate）这个可以适合我的情况。

我偶然发现了我的问题的解决方法：wxpython提供了一个名为Hypertreelist的类，它与WXPYTHON3 TREELISTCTRL非常相似，并且WXPYTHON3和WXPYTHON3和WXPYTHON3和WXPYTHON3和WXPYTHON3和WXPYTHON44。/p>

https://wxpython.org/phoenix/docs/html/wx.lib.agw.hypertreelist.hypertreelist.hypertreelist.html

特别是以传统方式接受双击的订阅：

self.tree.GetMainWindow().Bind(wx.EVT_LEFT_DCLICK, self.OnLeftDClick)

在我的情况下，从TreelistCtrl转换为Hypertroelist WX3时，只需要进行两次更改：

tree.SetBackgroundColour('white')
tree.SetImageList became tree.AssignImageList
