Zoom mouse mode locks in when mouse pointer leaves the viewport

[fedorov]

If I click right mouse button (zoom), and accidentally the mouse pointer leaves the viewport area while zoom mode is activated, zoom mode is locked, and remains active after I release the right mouse button.

Thanks for the report! I'm not reproducing this on Ubuntu with X Window System.

Looks like your browser is not getting events when your cursor is out of the browser window. When I hold mouse down, the view still zooms while mouse moves outside the browser window. Thats unlike your GIF. Tight security on your (Wayland?) windowing system or browser? Would be good to fix our input handling if that is the case.

I tried with these combos:

• https://volview.kitware.app/ and https://volview-dev.kitware.app/
• Firefox 119 and Chrome 118

Steps taken:

1. Load VolView
2. Load CTA Head and Neck sample.
3. Right mouse down in 2D view.
4. Move mouse out of browser window.
5. Right mouse up.
6. Move mouse back into 2D view -> No zooming, view does not change == expected.

Sorry, I forgot to mention - I am on Mac Sonoma 14.0 (same problem on Ventura), Chrome 118.0.5993.70.

I don't think I changed any default security settings.

and remains active after I release the right mouse button.

Correction: until I click right mouse button in the viewport again.
