Related to #256

This PR handles resizing column widths programmatically.

Fields that commonly need to be resized to view are resized based on content length.

I'm failing to understand what this is trying to address, can you clarify a bit? 🤔

why does this need to be QString::fromStdString("")

isn't this unrelated to what you want to do?

Why this sorting scheme?

Sorting by nodeid was simply to have sorting functionality for that column as opposed to no sorting functionality.

Please describe the goal, what is trying to improve and how it relates to #256. Looks like #256 conflicts with QHeaderView::ResizeToContents?

Goal of this PR/Discussion
  • Ideally formatting the initial column widths can reduce the number of click events the user needs to perform to be able to view the data presented.
  • Reducing click events where ever possible is ideal for normal users & tremendously valuable for scenarios where the user doesn't interact with this software primarily with mouse/touch methods.
Motivations for /gui fork as far as I can tell...
  • It is rooted in improving UI/UX (User Experience)
  • REVIEW ISO 9241-210:2019(en)
  • It is really impractical to require /gui PRs have to restate basic GUI/UI/UX motivations every time.

Concept NACK.

There are some concerns about QHeaderView::ResizeToContents.

  1. It increases complexity in such a way that could lead, at some scale, to deteriorating the GUI responsiveness
  2. From Qt docs:

The size cannot be changed by the user...

Usually, in this project, we strive do not make decisions instead of users in such questions :)

  1. Some users could feel uncomfortable with possible continuous reflowing of the peers table. I'm among of them.

Concept NACK

This unnecessarily restricts the user-configurability of the GUI. Testing this PR, I am no longer able to resize the tabs on my own to my liking. Per Qt docs, this is because of the use of QHeaderView::ResizeToContents.

In general, we should ONLY restrict user freedom when there is good reason and motivation to do so. Tables are meant to be resized to one's liking; not everyone wants to see the User Agent string, and some may not want to see the full Address string (this is one reason why we have #276).

Users of the GUI do want to customize the sizing of various aspects of the interface and have that saved and restored. This is a precedent that has been set by the direction GUI development has taken, See #165, #194, #205, and #256.

Can we make it do this only until the user tries to manually resize a column?
