Description

......

定义一些Windows API函数和常量

user32 = windll.user32 gdi32 = windll.gdi32

def set_window_region(hwnd, radius): rect = win32gui.GetWindowRect(hwnd) width = rect[2] - rect[0] height = rect[3] - rect[1] hRgn = windll.gdi32.CreateRoundRectRgn(0, 0, width + 1, height + 1, radius, radius) if hRgn != 0: windll.user32.SetWindowRgn(hwnd, hRgn, True) windll.gdi32.DeleteObject(hRgn)

......

if name == 'main': api = API() window = webview.create_window('JS API example', html=custom_titlebar_html, js_api=api, frameless=True, background_color='#000000')

time.sleep(1)

webview.start(func=on_window_loaded)

The code makes the window have a white frame, like below:
