wxPython:鼠标右键单击不设置焦点

Question

我的GUI当前有右键单击选项(剪切、复制、粘贴)

然而，我意识到当我右键点击我的搜索栏(wx.SearchCtrl)尝试粘贴时，焦点没有设置到搜索栏上，因此我无法粘贴。

self.panel.Bind(wx.EVT_CONTEXT_MENU, self.OnShowPopup)

def OnShowPopup(self, event):
   """ Obtain right-click selection """
   pos = event.GetPosition()
   pos = self.panel.ScreenToClient(pos)
   self.panel.PopupMenu(self.rightClickMenu, pos)

def OnPopupItemSelected(self, event):
   """ Display right-click menu """
   item = self.rightClickMenu.FindItemById(event.GetId())
   text = item.GetText()
   elif text == "Paste":
      self.OnPaste()

def OnPaste(self, event = None):
   """ Paste content from clipboard """
   text = self.FindFocus()
   if text:
      if isinstance(text, wx.TextCtrl):
         text.Paste()

这是我的想法:当鼠标右键点击时得到鼠标的位置.然后使用该位置在持有该位置的Ctrl上设置焦点。

这个是可能的吗？还是有更好的解决方案？

Answer 1

保存执行右键单击的对象，然后选择“粘贴”后进行setFocus。event.GetEventObject().SetFocus()不能工作的原因很可能是因为在从PopupMenu中选择粘贴之后，TextCtrl失去了焦点。所以文本不会在那里打印

def OnShowPopup(self, event):
   """ Obtain right-click selection """
   pos = event.GetPosition()
   pos = self.panel.ScreenToClient(pos)
   self.rightClickSelected = event.GetEventObject()
   self.panel.PopupMenu(self.rightClickMenu, pos)

def OnPaste(self, event = None):
   """ Paste content from clipboard """
   self.rightClickSelected.SetFocus()
   if isinstance(self.rightClickSelected, wx.TextCtrl):
      self.rightClickSelected.Paste()

Answer 2

def OnShowPopup(self, event):
      """ Obtain right-click selection """

      pos = event.GetPosition()
      pos = self.panel.ScreenToClient(pos)
      event.GetEventObject().SetFocus()
      self.panel.PopupMenu(self.rightClickMenu, pos)

会很好我想..。
