Or perhaps it should be a generator? Anyway, as it stands, you can use it like so: struct to the rescue! It would be nice to wrap this up into a class, implementing a file-like interface, at some point. The first byte of this string must contain the total length of the string. When sending the win32con.EM_GETLINE, you need to pass a string, into which the line of text will be inserted. The only complicated bit here is the struct stuff. Linelength = win32gui.SendMessage(hwnd, win32con.EM_GETLINE, line, linetext) Linecount = win32gui.SendMessage(hwnd, win32con.EM_GETLINECOUNT, 0, 0) Here's a function which will get it for you: An edit control is one of these - it has lines of text rather than just text. But other classes don't have the kind of text that win32gui.GetWindowText() sets. The thing is, this works for some classes of window - you can use win32gui.GetWindowText() to get the text of a button or a label, for example. 'But wait', you'll say, 'can't you use the win32gui.GetWindowText() function'? No, actually, you can't. I prefer the first form, but that's purely subjective.Īnd now, for my next trick, let's get the text from an Edit control. OkButton = findControl(optDialog, lambda hwnd, windowText, windowClass : windowClass = 'Button' and windowText = 'OK') You could do this more tersely with a lambda, by the way: OkButton = findControl(optDialog, findAButtonCalledOK) Return windowClass = 'Button' and windowText = 'OK' OptDialog = findTopWindow(wantedText='Options')ĭef findAButtonCalledOK(hwnd, windowText, windowClass): # Define a function to find our button Win32gui.SendMessage(hwnd, win32con.WM_LBUTTONUP, 0, 0)

Win32gui.SendMessage(hwnd, win32con.WM_LBUTTONDOWN, 0, 0) I'll just give a few simple examples, from which you should be able to extrapolate most things that you might need to do.Ī great many of these actions are class specific - you can select one or many of a combo box's items, for example, but a button doesn't have items to select. Anything that you can do with a mouse or a keyboard can be automated.

There are, of course, loads of things you can do with a control. See Driving win32 GUIs with Python, part 1 and Driving win32 GUIs with Python, part 2. Some things you can do with a control once you have it.
