如果您的目标是向下滚动数据包列表，您可以使用

# workaround for set_focus() failure on uia backend
app_win32 = Application(backend="win32").connect(path=r"wireshark.exe")
app_win32.window(best_match='Qt5QWindowIcon').set_focus()
PL.wheel_mouse_input(wheel_dist=-10) # negative wheel_dist means scroll down

或者尝试使用PL.type_keys('{VK_DOWN}')滚动数据包列表。

数据包列表(QTreeView小部件)的IsScrollPatternAvailable属性值为false，因此PL.scroll("down", "line", 1)原因错误消息“树”数据包列表“不可滚动”。此外，inspect.exe不会在PacketList的子级中显示滚动条。

此外，您还可以尝试另一种方法:获取数据包列表的右下角坐标，从中减去(5,5)或其他增量，然后单击到这一点。类似于(这段代码只是演示了idea，因为在最新的Wireshark版本上发送点击到错误的坐标，这可能是一个与Qt相关的问题)：

arrow_coords = (PL.rectangle().right - 5, PL.rectangle().bottom - 5)
for i in range(N):
    PL.click_input(coords=arrow_coords)
