Subject: file chooser: Improve column sizing
X-Git-Tag: archive/raspbian/4.4.1+ds1-2+rpi1^2~18^2~24^2~9164
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=22294a4a0d9edd101dd9d1f9df92b54362454d71;p=gtk4.git

file chooser: Improve column sizing

Allow the name and location columns to be resized, but arrange
for their sizing to be reset when the column layout changes (either
by the location column appearing/disappearing, or by the time
column changing between mtime and atime. This gives a decent
compromise between good automatic sizing and user control.
