Subject: fix crash: send non-floating window with floating parent to scratchpad (thanks pkordy)
X-Git-Tag: 4.4~101
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=da2b47c1e5d145c5029421129264dfaa986d94f5;p=i3%2Fi3

fix crash: send non-floating window with floating parent to scratchpad (thanks pkordy)

Fix a crash that occured when moving a window to the scratchpad that is
seemingly floating to the user, but actually a descendant of a floating
parent con (and itself non-floating). If that is the case, move the
floating parent container to scratchpad instead of the window.

fixes #740
