[MC-140646] Text fields don't scroll while selecting text with Shift

The bug

If you have a text, in the chat box or in a command block or structure block or etc, that is too long and can't be showed up completely, and you try to select a part of it with holding Shift+Arrow, the selection continues beyond whats already being displayed in the text field but the text field doesn't scroll to see what you are selecting.

This is still a problematic bug to going into 1.14 release. I understand that most hardened creators may not come across this issue working with functions or pasting everything into command blocks but some of us like to again select text in game larger than the visible text box.

I would like to provide information on the "command block" part of this bug:

The bug

When selecting text in a command block the text does not scroll.

How to reproduce

Try to make a selection of text (with Shift+Arrows) in a command block on a long command that goes beyond the frame.

Example

Here is what is excepted:

[media]

Here is what is happening now in 1.14:

[media]

Note

This bug does not occur in 1.13, 1.13.1, 1.13.2 and earlier versions. It is only a problem in 1.14. Before, everything worked fine.

This bug is really annoying for map creators so please, fix this bug before the official release of 1.14!

ZeNico13 2019-04-23T19:17:03Z

Still in 1.14 Release! It is very bad for map creators! Especially that the bug does not have to be hard to fix...

FACS01 2019-04-23T23:31:30Z

I want to make sure that, when you fix this bug, also look at this one. Both are related to text field and Shift key.

Also may I add that, MC-155958 is a duplicate of MC-121772. It has nothing to do with this bug.

Still in latest snapshot to date; being 19w37a
Next snapshot really needs to focus on UI fixes, no matter if they are low priority issues.
This is particularly annnoying, that is all.

In 1.15.1 there is the same bug...

FACS01 2020-02-16T21:04:50Z

I'm not sure but maybe when Workflow changed from Global Mojang to Java, this bug's assigned priority got lost? Can't find it on Details.

Jinx Ll 2020-03-29T19:48:58Z

Every time I do anything on minecraft with commands this bug annoys me. Every. Single. Time. Pleeeeeease fix asap.

Nope. 2020-04-13T19:58:41Z

can we just mention how a 16-month old bug with 45 votes hasn't even been assigned a priority by Mojang yet? I love your work, but this is beginning to suggest incompetence as a company.

Jatzylap 2020-06-11T19:53:20Z

Confirmed for 1.16-pre4

Mateus Pereira Milbradt 2020-09-01T21:45:34Z

This happens when you scroll to the left too

DelimanCZ 2021-03-16T20:39:25Z

Oh god, please FIX IT already! This is so annoying small bug and it takes Mojang years to fix it, like every single thing they break in their game. The game literally consists of billion small bugs, that they even had right in the game in the old better versions, but they broke it.

Can confirm in 1.17 Pre-release 4.

SoloAlguien 2021-06-20T19:23:07Z

Can confirm in 1.17 and 1.17.1 Pre-release 1.

null 2021-07-07T04:44:04Z

Code analysis based on Minecraft 1.17.1 with yarn mappings.

Note that selectionEnd is where the selection initially started, and selectionStart is where the cursor currently is. Since selectionEnd doesn't change when highlighting text, it is not updated:

net.minecraft.client.gui.widget.TextFieldWidget#setCursor(int)

this.setSelectionStart(cursor); // Move the cursor
if (!this.selecting) {
    this.setSelectionEnd(this.selectionStart); // selectionEnd does not need to be updated when selecting
}
...

The problem is that the scrolling logic is handled in setSelectionEnd, so it is skipped while selecting.

To fix this, the scrolling code should be moved to a separate method, and it should be invoked in setCursor even when selecting.
