Scroll horizontally with Shift + mouse wheel

[Justinas365]

Problem Description

Would you be able to include horizontal scroll with Shift+mousewheel.

This feature is in VS Code or SAS and it helps to review either the code if the line is long or view DataFrame with lots of columns

Versions

• Spyder version: 4.2.0
• Python version: 3.8
• Qt version: 4.7.7
• PyQt version:
• Operating System name/version: Windows 10

Hey @Justinas365, thanks for reporting and sorry for the delay in coming back to you. Could you post a screenshot of what you mean by your request? Thanks!

Hello, sorry for my late reply.

So the image below contains a long line. At the bottom you can see that a horizontal scroll bar appeared. It would be really handy if I could scroll left or right when I click Shift and then spin a mouse wheel either up or down.

I think this feature would be particularly when exploring DataFrames in variable explorer. Imagine if you had 200 columns, it would be a lot more precise and faster to scroll horizontally with Shift and mouse wheel up and down instead of grabbing horizontal bar with a bouse and dragging it.

This is a feature I always use in SAS.

I understand this is not a must as there are other outstanding issues to fix so not something to worry too much.

Thank you

Currently, pressing Shift + mouse wheel up/down is already used to jump up/down code (every move of the wheel skips around 50 lines up/down in my version).

However, seeing that the mouse wheel is already used to scroll vertically up/down code, it seems more intuitive to assign Shift + mouse wheel to scroll horizontally left/right instead of still moving up/down code (even if in larger chunks), and I can't find an option to change it.

This is also how Google Colab works...having gotten used to it, I always get annoyed when I use Shift + mouse wheel in Spyder to view a long line but instead end up jumping down 50 lines.

As @Justinas365 mentioned, this is not a major issue, but it would be nice to have.

Unfortunately, Shift + mouse wheel is already used to do zoom in/out. Do you have other suggestions?

As mentioned, at least in my case, Shift + mouse wheel scrolls up/down code in larger jumps; it is Ctrl + mouse wheel that does zoom in/out.

Is it not possible to let the user change their behaviour, similar to how the key bindings can be changed in Tools > Preferences > Keyboard shortcuts?

No, it's not possible right now. We have to implement that functionality first.

Horizontal scrolling with shift + mouse wheel is the default in macOS and Linux. In this sense, the Spyder editor deviates from the unofficial norm.

For anyone who is also affected by this issue, I have noticed that there is a work-around until (maybe) this is resolved - if you move your mouse/cursor on to the horizontal scroll bar and use the mouse wheel, you will be able to scroll horizontally.

IMO still not as convenient as pressing Shift + mouse wheel (because you don't have to move your mouse and ensure it is placed directly on the horizontal scroll bar)...but it might be just enough for some.

@Justinas365, you can use alt + mousewheel in spyder IDE, if you are stuck till now. I just saw this issue.😅😅

use Alt + mouse scroll That should do the job for you.
