Subject: gridview: Allow starting rubberband in empty space below last row
X-Git-Tag: archive/raspbian/4.8.3+ds-2+rpi1~3^2~20^2~4^2~38^2~7
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=1e9a36ffa8d198212cde130a021256fd142ba6c5;p=gtk4.git

gridview: Allow starting rubberband in empty space below last row

Rubberband does not work when initiated past the last row
(warning is printed "Could not start rubberbanding: No item).

Clamp y at the max height of the widgets in the gridview

Fixes: #3462
