在窗口内查找控件的句柄 [英] Finding Handle of a control inside a window

问题描述

给定父窗口的句柄，如何获取该窗口内按钮的句柄?

Given the handle to a parent window, How can I get the handle of a button inside this window?

我正在使用 win32api.sendMessage( ) 将值传递给窗口.我想使用 BM_CLICK 来点击有问题的按钮.

I'm using win32api.sendMessage( ) to pass values to a window. I want to use BM_CLICK to click on the button in question.

import win32api
import win32gui
import win32con

#get handle of the window I want

hwnd=win32gui.FindWindow(0,"SOME TITLE")

#btnHnd= (NEED CODE HERE TO GET THE HANDLE OF THE BUTTON INSIDE hwnd)

win32api.SendMessage(btnHnd, win32con.BM_CLICK, 0, 0)

推荐答案

btnHnd= win32api.FindWindowEx(hwnd, 0 , "Button", "#Title")

是找到子窗口句柄的方法，前提是按钮是父级的直接子级，而不仅仅是后代

is the way to find the handle of the child window, provided the button is a direct child of the parent, not just a descendent
