Is it possible to scroll up/down with middle-click ? And/or move other view separator left/right ?

shodanx2

Hi,

I wanted to move the “other view” separator with more ease

That bar in the middle

And I tried middle-click-drag, and it does nothing, there is no action associated with that button

I was wondering if I could make a plugin that
When I middle-click-drag left and right, it would move the separator left and right ?

Or maybe a plugin that does this already exists ?

ok I’ll wait

Thanks !

Left click and drag isn’t easy enough for you?

I think maybe what was meant was “middle click anywhere in either window” to initiate the desired behavior?

Yes, you could.

I for one don’t recall one that does this.

Hello,

Yes by that I mean at positionning the cursor on a 15 pixel wide bar and then left-click-dragging it left and right, is more difficult than.

Placing the cursor anywhere on the window and middle-click-dragging left and right.

This is probably because I’m an altsnap user with the hotclick function enabled that I noticed this.

https://github.com/RamonUnch/AltSnap

In my operating system, I press my hotclick button and I can move window around, no matter when I click them, and I right-click-resize them also by click them almost anywhere (well, resizing is by quadrant)

And so, I find I often need to swipe the other view separator left and right, relatively often and I find that comparatively finicky compared to moving around anything else on my desktop.

I also use “scroll anywhere” in my browser

https://addons.mozilla.org/en-CA/firefox/addon/scroll_anywhere/

Which allows me to middle click drag anywhere on a page and very quickly scroll it up and down. One windowheight of dragging equals 100% document scroll height, so the most you have to scroll is one page height to get anywhere in the document, this is a kind of “rough scrolling” and I finish fine scrolling with my mouse that has a semi-automatic “smooth scroll” function (electromagnetic clutch that opens when you scroll it fast)

So I thought that these could be easily done in notepad++. I figured I would ask before trying to make it myself.

Since the middle-click-drag is not currently bound to any action, I think a script that listens for middle-click-dragging. Then for every pixel of left-right movement, move the other view separator by an equal amount of pixel in the same (or opposite ? maybe some people would prefer opposite) direction. And maybe also for up/down movement, scroll the document up and down by a percentage of the document height by the amount of cursor movement divided with the windowheight of notepad++, in the view that was initially click at the start of middle-click dragging

I tried doing this with pythonscript however it appears that pythonscript does not have mouse movement event hooks and it would need an external application (like altsnap and x mouse button control) to monitor the mousemovements ? but maybe a “real” plugin could do it ?

Here is a tentative non-working pseudo code of what that might look like

from pynput import mouse
from time import sleep
from Npp import notepad

initial_x = None
initial_splitter = None

def on_click(x, y, button, pressed):
    global initial_x, initial_splitter
    if button == mouse.Button.middle:
        if pressed:
            initial_x = x
            initial_splitter = notepad.getSplitterPos()[0]
        else:
            initial_x = None

def on_move(x, y):
    global initial_x, initial_splitter
    if initial_x is not None:
        delta = x - initial_x
        notepad.setSplitterPos(initial_splitter + delta)

listener = mouse.Listener(on_click=on_click, on_move=on_move)
listener.start()

# Keep script running
while True:
    sleep(1)

You can do it in a PythonScript, but you have to obtain the window handle for the control of interest and then set up a hook function to be able to monitor its messages. When you get the message(s) of interest, then run the logic(s) that you’d like to have.
