Good day,

I've been looking at the pywin32 coding, but feel stuck at implementing
correct approach on basics of window.
So far the basic is from an example that I found on internet.

The question is on how to start using WM_CREATE to define the basic layout
of window, for example splitter, buttons, boxes etc?
Any tips on how to strip C/C++ examples to more pywin32 like structures?

import win32gui
import win32con

class Window:
    def window_proc(self, hwnd, msg, wparam, lparam):
        match msg:
            case win32con.WM_CREATE:
                pass
            case win32con.WM_CLOSE:
                win32gui.DestroyWindow(hwnd)
            case win32con.WM_DESTROY:
                win32gui.PostQuitMessage(0)
        return win32gui.DefWindowProc(hwnd, msg, wparam, lparam)

    def create_window(self):
        wc = win32gui.WNDCLASS()
        wc.lpfnWndProc = self.window_proc
        wc.lpszClassName = "PythonWindowClass"
        wc.hbrBackground = win32gui.GetStockObject(win32con.WHITE_BRUSH)
        wc.hCursor = win32gui.LoadCursor(None, win32con.IDC_ARROW)

        class_atom = win32gui.RegisterClass(wc)
        style = win32con.WS_OVERLAPPEDWINDOW | win32con.WS_CLIPCHILDREN
        hwnd = win32gui.CreateWindow(
            class_atom,
            "Python Window",
            style,
            100, 100, 500, 400,
            0, 0, 0, None
        )

        win32gui.ShowWindow(hwnd, win32con.SW_SHOWNORMAL)
        win32gui.UpdateWindow(hwnd)

        message = win32gui.GetMessage(None, 0, 0)
        while message[0]:
            win32gui.TranslateMessage(message[1])
            win32gui.DispatchMessage(message[1])
            message = win32gui.GetMessage(None, 0, 0)


if __name__ == "__main__":
    app = Window()
    app.create_window()

With best regards,
JP
