这是一个调用user32.SendInput（）的工作模块。
不完美，但可用。
编辑：
昨天，我使用一个类制作了一个版本，并在正在运行的tkinter应用程序中使用它。当我有时间清理它时，会把它放在这里。
在下面的文档字符串中添加了此代码：
[如果我在个人资料中的文件夹中工作，可以。
这些问题是在另一个分区上工作时发生的。
文件权限还可以，所以不知道阻止了SendInput的内容。]
SciTE仍需要 完整的确切 窗口标题。
#!/usr/bin/python# -*- coding: utf-8 -*-''' send_input for python 3, from jh45dev@gmail.compre from Daniel F is adapted here. The original is at:http://mail.python.org/pipermail/python-win32/2005-April/003131.htmlSendInput sends to the window that has the keyboard focus.That window must not be minimized.There seem to be some strange limitations with user32.SendInput()Here is what happened in my testing (on Vista sp2). [edit: It is OK if I work from a folder within my profile. These problems happened when working on another partition. File permissions were OK, so do not know what blocked SendInput.]1I opened Notepad from the Start menu,then in Notepad opened test.txt,and all worked fine.2I opened Notepad by opening test.txt in Explorer.find_window() found Notepad, but user32.SendInput() had no effect.If Notepad was minimized, it did not get restored or focussed.The same happened with SciTE and Notepad2.Another strangeness:For SciTE I had to put in the whole window title, eg "test.txt - SciTE",but for Notepad and Notepad2, only the app name, eg "Notepad".'''import ctypes as ctfrom win32con import SW_MINIMIZE, SW_RESTOREfrom win32ui import FindWindow, error as ui_errfrom time import sleepclass cls_KeyBdInput(ct.Structure): _fields_ = [ ("wVk", ct.c_ushort), ("wScan", ct.c_ushort), ("dwFlags", ct.c_ulong), ("time", ct.c_ulong), ("dwExtraInfo", ct.POINTER(ct.c_ulong) ) ]class cls_HardwareInput(ct.Structure): _fields_ = [ ("uMsg", ct.c_ulong), ("wParamL", ct.c_short), ("wParamH", ct.c_ushort) ]class cls_MouseInput(ct.Structure): _fields_ = [ ("dx", ct.c_long), ("dy", ct.c_long), ("mouseData", ct.c_ulong), ("dwFlags", ct.c_ulong), ("time", ct.c_ulong), ("dwExtraInfo", ct.POINTER(ct.c_ulong) ) ]class cls_Input_I(ct.Union): _fields_ = [ ("ki", cls_KeyBdInput), ("mi", cls_MouseInput), ("hi", cls_HardwareInput) ]class cls_Input(ct.Structure): _fields_ = [ ("type", ct.c_ulong), ("ii", cls_Input_I) ]def find_window( s_app_name ): try: window1 = FindWindow( None, s_app_name,) return window1 except ui_err: pass except: raise try: window1 = FindWindow( s_app_name, None, ) return window1 except ui_err: return None except: raisedef make_input_objects( l_keys ): p_ExtraInfo_0 = ct.pointer(ct.c_ulong(0)) l_inputs = [ ] for n_key, n_updown in l_keys: ki = cls_KeyBdInput( n_key, 0, n_updown, 0, p_ExtraInfo_0 ) ii = cls_Input_I() ii.ki = ki l_inputs.append( ii ) n_inputs = len(l_inputs) l_inputs_2=[] for ndx in range( 0, n_inputs ): s2 = "(1, l_inputs[%s])" % ndx l_inputs_2.append(s2) s_inputs = ', '.join(l_inputs_2) cls_input_array = cls_Input * n_inputs o_input_array = eval( "cls_input_array( %s )" % s_inputs ) p_input_array = ct.pointer( o_input_array ) n_size_0 = ct.sizeof( o_input_array[0] ) # these are the args for user32.SendInput() return ( n_inputs, p_input_array, n_size_0 ) '''It is interesting that o_input_array has gone out of scope by the time p_input_array is used, but it works.'''def send_input( window1, t_inputs, b_minimize=True ): tpl1 = window1.GetWindowPlacement() was_min = False if tpl1[1] == 2: was_min = True window1.ShowWindow(SW_RESTORE) sleep(0.2) window1.SetForegroundWindow() sleep(0.2) window1.SetFocus() sleep(0.2) rv = ct.windll.user32.SendInput( *t_inputs ) if was_min and b_minimize: sleep(0.3) # if the last input was Save, it may need time to take effect window1.ShowWindow(SW_MINIMIZE) return rv# define some commonly-used key sequencest_ctrl_s = ( # save in many apps ( 0x11, 0 ), ( 0x53, 0 ), ( 0x11, 2 ),)t_ctrl_r = ( # reload in some apps ( 0x11, 0 ), ( 0x52, 0 ), ( 0x11, 2 ),)def test(): # file > open; a non-invasive way to test t_ctrl_o = ( ( 0x11, 0 ), ( 0x4F, 0 ), ( 0x11, 2 ), ) # writes "Hellon" # 0x10 is shift. note that to repeat a key, as with 4C here, you have to release it after the first press t_hello = ( ( 0x10, 0 ), ( 0x48, 0 ), ( 0x10, 2 ), ( 0x45, 0 ), ( 0x4C, 0 ), ( 0x4C, 2 ), ( 0x4C, 0 ), ( 0x4F, 0 ), ( 0x0D, 0 ), ) l_keys = [ ] ## l_keys.extend( t_ctrl_o ) l_keys.extend( t_hello ) l_keys.extend( t_ctrl_s ) ## s_app_name = "SciTE" ## s_app_name = "(Untitled) - SciTE" s_app_name = "test.txt - SciTE" ## s_app_name = "Notepad2" ## s_app_name = "Notepad" window1 = find_window( s_app_name ) if window1 == None: print( "%r has no window." % s_app_name ) input( 'press enter to close' ) exit() t_inputs = make_input_objects( l_keys ) n = send_input( window1, t_inputs ) ## print( "SendInput returned: %r" % n ) ## print( "GetLastError: %r" % ct.windll.kernel32.GetLastError() ) ## input( 'press enter to close' )if __name__ == '__main__': test()
