Subject: dnd: Add a private struct
X-Git-Tag: archive/raspbian/4.4.1+ds1-2+rpi1^2~18^2~22^2~336
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=eb9105aceaba6d8fa1e646a633b374c65e0d65c4;p=gtk4.git

dnd: Add a private struct

And put member veriables into it.

Also fix backends to use accessors instead of direct access.
