pythongui計算器

❶ 用python win32 獲得計算器里的計算結果

給你一個思路。用python的win32gui可以枚舉所有窗口句柄，想辦法獲取窗口句柄，然後通過GetWindowText()方法來獲取窗口的標題，也就是結果所在的窗口句柄。

我用WIN32試了一下，我是hook了滑鼠所在的句柄，但當滑鼠指向結果時，結果的窗口句柄獲取不到，只能獲取到結果窗口的上一個窗口的句柄（也就是你圖中的00280756的句柄），但可以通過枚舉子窗口來獲取（也就是枚舉你圖片中的002F0854句柄），然後經過一系列匹配和判斷最終得到結果的值。

#encoding:gb2312

importwin32gui

def_MyCallback(hwnd,extra):
hwnds=extra
hwnds.append(hwnd)

def_CallBack(hwnd,extra):
value,m_index=extra
ifwin32gui.GetClassName(hwnd)=='Static':
m_index.append(None)

iflen(m_index)==4:
value.append(win32gui.GetWindowText(hwnd))

defTestEnumWindows():
windows=[]
results=[]
win32gui.EnumWindows(_MyCallback,(windows))
i=0
forhwndinwindows:
ifwin32gui.GetClassName(hwnd)=='CalcFrame':
m_index=[]
win32gui.EnumChildWindows(hwnd,_CallBack,(results,m_index))
i+=1
forresultinresults:
print'計算器的結果為：',result
TestEnumWindows()

這樣更好一些，可能有些特徵不同。我是枚舉所有窗口，然後獲取窗口的classname為CalcFrame的窗口，然後再枚舉CalcFrame的子窗口，然後判斷第4個出現的Static控制項就是結果的控制項。

❷ python計算器

python計算器實現：

wx.TextCtrl（文本輸入控制項），這個作為計算器的顯示屏，點擊數字時用AppendText方法將數字添加至文本末尾，要取出數字時用GetValue方法，點擊運算符時要將文本框中的數字清空（先存儲）用Clear方法然後還有將操作符保存，點擊等號後要將第二個操作數存儲，然後用int方法將字元串轉換為數字，計算後用SetValue方法將結果送入文本框，具體代碼如下：

importwx
#beginwxGlade:extracode
#endwxGlade
classMyFrame(wx.Frame):
def__init__(self,*args,**kwds):
#beginwxGlade:MyFrame.__init__
kwds["style"]=wx.DEFAULT_FRAME_STYLE

❸ 用python操作Windows的計算器。

pyhook可以抓到鍵。

不過這里只需要消息就可以了，win32api中的windows的message

使用vc中的消息 工具，抓鍵盤消息。然後再把這個消息包裝一下用pywin32中的API發送過去。

我以前用pyhook加pywin32, 控制過一個游戲，做外掛。

也用pywin32的com介面控制過excel
