No Mouse support in Windows 10

See original GitHub issue

I have a full screen application written with prompt toolkit.

self.app = Application(layout=layout, full_screen=True, mouse_support=True...)

The application works fine in Mac and Linux envs. But cannot scroll in Windows 10 command prompt. What is the reason for this and can it be fixed? Or is there an alternative (like enabling scrolling with keyboard)

Thank you for reporting this issue @yzhang1994!

This looks like a bug. I’m not yet sure what’s going on. It looks like the same issue is present in prompt_toolkit 2.0.

Hi @yzhang1994

I was able to fix this in win32.py by doing this ( see #1232 ):

def enable_mouse_support(self) -> None:
        ENABLE_MOUSE_INPUT = 0x10
        ENABLE_EXTENDED_FLAGS = 0x0080
        ENABLE_QUICK_EDIT_MODE = 0x0040
        handle = HANDLE(windll.kernel32.GetStdHandle(STD_INPUT_HANDLE))

        original_mode = DWORD()
        self._winapi(windll.kernel32.GetConsoleMode, handle, pointer(original_mode))
        self._winapi(
            windll.kernel32.SetConsoleMode,
            handle,
            # on some windows builds mouse events do not register
            # when quick edit mode is enabled, this is not documented
            # see https://docs.microsoft.com/en-us/windows/console/setconsolemode
            (
                original_mode.value | ENABLE_MOUSE_INPUT | ENABLE_EXTENDED_FLAGS
            ) & ~ENABLE_QUICK_EDIT_MODE
        )

Maybe this will work for you?
