Today, I participated in the Qt Nagoya study group.
It was my first time attending last time, so today was my second time.

Last time, due to [first time attending] + [first time seeing Qt (excuse)] + [setup failures causing many errors], I mostly just panicked and it ended. So today, I decided what I wanted to achieve and participated.

The result of the day is this.

By the way, the image shown in the video is borrowed from ImageNet.

I wanted to try implementing MVVM in Qt like in WPF, so I tried creating a mechanism to bind list-formatted model data to the View.

On the C++ side, I gathered image files from an arbitrary directory, created a list-formatted property using QQmlListProperty, and bound it to the View.

For the View, I set the left side as a ListView and the right side as a GridView, and plugged the same QQmlListProperty mentioned above into the model for each. I also deliberately synchronized the selection state of the ListView and GridView via a C++ property.
Putting aside the appearance, functionally, I think it turned out quite well for me.

Since I went through a lot of trial and error, the source code is too messy to publish, but I plan to rewrite it all and upload it to GitHub eventually.

Today was fun.
