Presentation mode?

[roweryan]

Is there a way to get Notepad++ to enter presentation mode? I would like to stop the screensaver kicking in all the time (IT set it to 5 minutes and I cannot change it). Thanks.

Ah, those I.T. clowns…always doing dumb things.

Sounds like what you need is a mouse-jiggler.

So, as I often do, I grabbed the jiggler script I use, and I cleaned it up for forum posting. The script runs via the PythonScript plugin and executes behind the scenes whenever your Notepad++ is running, preventing your computer from entering screensaver/sleep mode.

Curiously, I notice if I have Visual Studio IDE running in addition to Notepad++, my computer WILL sleep after the I.T. prescribed timeout – I have no idea why this is.

Here’s MouseJiggleDaemon.py:

    _fields_ = (
        ('dx', LONG),
        ('dy', LONG),
        ('mouseData', DWORD),
        ('dwFlags', DWORD),
        ('time', DWORD),
        ('dwExtraInfo', ULONG_PTR)
        )

class _INPUTunion(ctypes.Union):
    _fields_ = (
        ('mi', MOUSEINPUT),
        )

def MouseInput(flags, x, y, data): return MOUSEINPUT(x, y, data, flags, 0, None)
def Input(structure): return INPUT(INPUT_MOUSE, _INPUTunion(mi=structure))
def Mouse(flags, x=0, y=0, data=0): return Input(MouseInput(flags, x, y, data))

class INPUT(ctypes.Structure):
    _fields_ = (
        ('type', DWORD),
        ('union', _INPUTunion)
        )

def sendInput(*inputs):
    nInputs = len(inputs)
    LPINPUT = INPUT * nInputs
    pInputs = LPINPUT(*inputs)
    cbSize = ctypes.c_int(ctypes.sizeof(INPUT))
    return ctypes.windll.user32.SendInput(nInputs, pInputs, cbSize)

def sendMouseMoveDeltaXY(x, y):
    flags = MOUSEEVENTF_MOVE
    event = Mouse(flags, x, y, 0)
    return sendInput(event)

class MJD(object):

    def __init__(self):
        self.jiggle_thread = threading.Thread(target=self.jiggle_thread_function, args=(1,))
        self.jiggle_thread.daemon = True  # thread won't stop until parent ends
        self.jiggle_thread.start()

    def jiggle_thread_function(self, name):
        multiplier = 1
        while True:
            sendMouseMoveDeltaXY(multiplier, multiplier)
            multiplier *= -1
            time.sleep(5.0)  # use this so we don't continuously use CPU time

if __name__ == "__main__":
    try:
        mjd
    except NameError:
        mjd = MJD()

You can set it up for automatic use by adding these two lines to your user startup.py file:

import MouseJiggleDaemon
mjd = MouseJiggleDaemon.MJD()

and by configuring your PythonScript to run “at startup” by choosing this setting:

@alan-kilborn it is working thank you.

Maybe this could make it to mainline np++ one day :)

@roweryan said in Presentation mode?:

It seems perfect as an add-on script.
Glad that it works for you.

Now you have a reason to never exit N++.
If you need such a reason.
