Hangs when using keyboard navigation in Linux

[agentmorris]

First, props on a fantastic tool; this is the fastest, most user-friendly tool I've come cross to load and preview YOLO-formatted annotations.

I am using Ubuntu 22.04, and I can load an image set, and navigate between images with the sidebar and the arrow keys, but when I hit "ctrl-a" or "ctrl-d" to switch between images, the image number indicator advances correctly, but I just get a permanent spinning wheel.

Nothing happens in the console when I hit the shortcut key; the only thing I see in the console is a warning from just after loading the images, which may or may not be relevant:

(BoundingBoxEditor:2673766): Gdk-WARNING **: 16:44:00.036: XSetErrorHandler() called with a GDK error trap pushed. Don't do that.

"Hangs" may be a little misleading... the app is still responsive, the image just never loads, and clicking on other images (or the arrow keys) no longer loads images.

Thoughts?

Thanks!

Also, this feels related, so rather than filing a separate issue, just commenting here... I can ctrl-wheel to zoom in and out of an image, but when I ctrl-click to pan, the icon correctly changes to the little hand, but I can't actually pan the image. This is all on Ubuntu 22.04.

Hi @agentmorris! Sorry for the late response (for some reason I did not get a notification). Thanks for reporting this issue - I remember also sometimes getting this problem on Ubuntu. Will look into it when I find the time!

• Zooming and panning issue (resolved via Fix scrolling computation #72).
• Image-view hanging issue caused by partial navigation key-combination release not triggering image loading (resolved via Fix partial navigation key-combination release handling #78).
