Subject: treeview: Do not set top row adjustment value while animating
X-Git-Tag: archive/raspbian/4.8.3+ds-2+rpi1~3^2~20^2~3^2~83^2
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=b4ade026f1bda444d9b6e60e9d8c2e18dad587ff;p=gtk4.git

treeview: Do not set top row adjustment value while animating

gtk_tree_view_top_row_to_dy, which is called from GtkTreeView's
size_allocate function, changes the adjustment value. Since this
conflicts with the animation when changing the active row, bail
out until the animation is finished.

Fixes #4550
