Animation for Presets and Comments fields is glitchy

[gschlafly]

Description

The CollapsibleBox method works great for minimizing the space that the Presets and Comments fields consume within the widget. However, the animation is glitchy, as shown in the screen recording below.

Solution ideas

• Make the nearby regions of fixed height instead of expandable height.
• Omit the animation effect by using a method other than the CollapsibleBox class, and have the surrounding fields move instantaneously.
• The napari-assistant plugin may similarly being using a dropdown area method for their info boxes. I observed what appeared to be an attempted animation when I hovered over the ? in the top right corner and some of the large buttons, as shown in the video below. So this glitchiness may be an issue with napari in general. @haesleinhuepf may also have some ideas on how to fix this glitchiness.

Hi all,

I presume it's a qt-issue or a napari issue. To know which of the two, I recommend reaching out to the napari-core devs to ask them about their opinion. They have weekly open community meetings, the perfect place to show stuff and ask for support:

I hope that helps. 🌞

Best, Robert

@gschlafly with the latest GUI changes, this seems more acceptable now.
