Reads attributes from exr header and display them in a window

[Wagyx]

Hello,
I have added a way to retrieve the EXR attributes from the file header and display them with a new info button that pops up a window. (like the help button).
I have struggled a bit with the window layout, it is not great.
Also if you change the current image when the window is enabled, the info is not updated. It reloads if you hide and show it again with the info button though.
I was thinking that maybe other information such as EXIF metadata could be added to it at some point.

Hi there, thanks for the contribution!

Like you already say, the UX needs some improvement for the feature to be merged, like the window automatically updating when the image changes.

I also spot a few minor issues with the code that should get fixed along the way. Some examples:

• Inconsistent formatting (I see places with missing spaces, wrong indentation, braces on separate lines where the rest of the codebase puts them on the same, etc.)
• Code duplication (the metadata window seems to share some parts with the help window which should be suitably abstracted out)
• Some public-facing data members (should be getters/setters)

Thanks again!

Thank you for the feedback. I'll work on those items.
What formatter do you recommend I use ? My IDE is VSCode and the default one was inconsistent with your formatting.

I have improved the display of the attributes and the window now updates when changing the selected image.

I just stumble upon this PR when cloning this repo and can comment a bit.

What formatter do you recommend I use ? My IDE is VSCode and the default one was inconsistent with your formatting.

In the project folder, there is a clang-format definition:
https://github.com/Tom94/tev/blob/master/.clang-format

In VSCode, you can configure it to reference this file for formatting your source code, ensuring that your code maintains a consistent style with the rest of the project.
