来自用户在字段中选择文本的wxPython事件?
如何在wx.TextCtrl、wx.lib.editor、wx.richtext和wx.stc等小部件中捕获用户文本选择的起点和终点?我应该参加什么活动 我只是在学习wxPython,并根据示例编写了以下基本代码来自用户在字段中选择文本的wxPython事件?,wxpython,Wxpython,如何在wx.TextCtrl、wx.lib.editor、wx.richtext和wx.stc等小部件中捕获用户文本选择的起点和终点?我应该参加什么活动 我只是在学习wxPython,并根据示例编写了以下基本代码 import wx import wx.lib.editor as editor class MyFrame(wx.Frame): def __init__(self, parent, title): wx.Frame.__init__(self, paren

-大卫有点晚了,但万一还是有帮助的话。您可以使用win32api模块:
import wx
import win32api
class MyTextCtrl(wx.TextCtrl):
def __init__(self, parent):
self.hwnd = self.GetHandle()
def _GetSel(self):
EM_GETSEL: int = 0xB0
n = win32api.SendMessage(self.hwnd, EM_GETSEL, 0, 0)
return win32api.LOWORD(n), win32api.HIWORD(n)
def IsFullTextSelected(self):
return self._GetSel() == (0, len(self.Value))
