Question

我写了wxTreeCtrl，我只想处理65到90之间的键码（Ascii：A-Z）。我不想自己处理任何其他密钥代码。在我处理了65到90之间的键之后，我如何能够中止我的事件并使用标准的“key down”-event来进行wxTreeCtrl？

班级定义：

class ConfigTreeCtrl(wx.TreeCtrl):

方法绑定：

self.Bind(wx.EVT_KEY_DOWN, self.OnKeyDown, self)

方法定义：

def OnKeyDown(self, event):         
    now = time.time()  
    keyCode = event.GetKeyCode()
    if (keyCode >= 65 and keyCode <= 90) or ( keyCode >= 48 and keyCode <= 57):
        if self.searchString == "":
            self.searchString = chr(event.GetKeyCode())
        elif (now - self.lastKeyDown) < 2:
            self.searchString += str(chr(event.GetKeyCode()))
        else:
            self.searchString = str(chr(event.GetKeyCode()))
    self.lastKeyDown = now
    self.GetItem(self.searchString, self.GetRootItem())

event.Skip()可以在基本wxWindows类或本机控件中进一步处理事件。所以在你的方法中应该引入类似的东西：

def OnKeyDown(self, event):         
    now = time.time()  
    keyCode = event.GetKeyCode()
    if (keyCode >= 65 and keyCode <= 90) or ( keyCode >= 48 and keyCode <= 57):
        if self.searchString == "":
            self.searchString = chr(event.GetKeyCode())
        elif (now - self.lastKeyDown) < 2:
            self.searchString += str(chr(event.GetKeyCode()))
        else:
            self.searchString = str(chr(event.GetKeyCode()))
    else:
        event.Skip()
        return
    self.lastKeyDown = now
    self.GetItem(self.searchString, self.GetRootItem())
