Horizontal scrollbar doesn’t shrink after the long line getting shortened

[EFanZh]

• VSCode Version: 1.6.0
• OS Version: Windows 10

Steps to Reproduce:

1. Create an empty file;
2. Type a long line until the horizontal scrollbar appears;
3. Delete that long line;
4. Observe that the horizontal scrollbar still exists.

If I resize the window, the horizontal scrollbar disappears, but If I only delete the long line, the horizontal scrollbar still exists.

We never got to implement that it shrinks :)

We do something very easy:

• when painting a viewport: scrollWidth = Math.max(scrollWidth, lines[i].getWidth())
• when relayouting: scrollWidth = 0.

@alexandrudima I think this bug (or feature) is somehow fixed (or implemented), can you verify it?

[alexdima]

No, I haven't fixed this yet.

Scroll in such a way that not all lines are visible in the viewport:

longest line longest line longest line longest line longest line longest line 



















a not so long line a not so long line

I might not go so far as to say this is crucial, but I think it is quite important. In my duplicate bug report I pointed out how touchpads can scroll horizontally and vertically at once, so the scrollbars can be quite a nuisance. Every other editor I've used resizes the viewport as soon as a long line is deleted.

If your implementation is as simple as you say in the second comment here, can't you simply reset scrollWidth whenever a long line gets deleted or becomes short enough to fit? A "long line" could be defined either as being >= scrollWidth or as anything too long for the viewport, I think either would work.

Hi, Any updates on this issue? :)

[realh]

There are two workarounds: enable Word Wrap, or press Ctrl-B/Cmd-B twice whenever the width needs to be corrected.

Thanks @realh! Just for reference: If GitLens's show-blame-per-line config is enabled, the trick won't work.
