# --- Floating panes clamped when the window shrinks (issue #5581, PR #5582) ---
|
||||
#
|
||||
# layout_resize clamps floating panes back inside the window when it shrinks:
|
||||
# move them and, only if they cannot fit, shrink them (never below
|
||||
# PANE_MINIMUM). A floating cell is the pane's content, so with the default
|
||||
# single-line border the clamp counts 1 cell of border per side, exactly as
|
||||
# layout_floating_args_parse does on creation; with no border it counts 0.
|
||||
# Each case below gets its own window, since resize-window fixes a window at
|
||||
# a manual size for the rest of its life.
|
||||
|
||||
# Case 1: a lone floating pane -- break-pane -W on a window's only pane --
|
||||
# takes the early-return path in layout_resize, added during PR #5582's
|
||||
# review round, since there is no tiled tree to walk.
