wxPython treeCtrl樹節點遞歸遍歷(復制)

下面是遞歸遍歷、獲取樹節點的方法。

    def getTreeAllText(self):
        '''獲取樹控件的全部文本'''
        result = []
        treeRoot = self.treeCtrl.GetRootItem()
        rootText = self.treeCtrl.GetItemText(treeRoot)
        result.append(u'┌'+rootText)
        def recursivelyGetTreeItem(tree,leval):
            ''' 遞歸遍歷TreeCtrl的所有孩子 '''
            (item,cookie) = self.treeCtrl.GetFirstChild(tree)
            while item.IsOk():
                ItemStr = u'├%s%s' % (u'─'*leval,self.treeCtrl.GetItemText(item))
                result.append(ItemStr)
                if self.treeCtrl.GetChildrenCount(item)>0:
                    leval+=1
                    recursivelyGetTreeItem(item,leval)
                    leval-=1
                (item,cookie) = self.treeCtrl.GetNextChild(item,cookie)
                
        leval = 0   #遞歸的子樹層次
        recursivelyGetTreeItem(treeRoot,leval)
        return '\n'.join(result)

 設置文本內容到剪貼板

def CopyToClipboard(text):
    do = wx.TextDataObject()
    do.SetText(text.encode('gb2312'))
    if wx.TheClipboard.Open():
        wx.TheClipboard.SetData(do)
        wx.TheClipboard.Close()
    else:
        wx.MessageBox("Unable to open the clipboard", "Error")
