When closing the last tab in a window (kill_tabpage -> kill_window), the surviving window's editor was not properly resumed. set_current_view only updates the active view pointer without triggering rendering recalculation. Adding resume() ensures notify_change(THE_FOCUS + THE_EXTENTS) is called, which forces proper font environment and layout recalculation. Fixes MoganLab#2009

Sorry, it's my fault. This issue is too old and seems to have become invalid, so I have closed it. |

Problem
Fixes #2009
When using "Documents in separate windows" mode with the Tab bar enabled,
closing a newly created tab causes the original document's rendering to
become inconsistent — the same text appears with different font metrics
and spacing than before.
Root Cause
In
kill_window()insidesrc/Texmacs/Data/new_window.cpp, when thelast tab in a window is closed,
set_current_view()switches to thesurviving window's view. But
set_current_view()only updates the viewpointer — it never calls
resume()on the editor.Without
resume(),notify_change(THE_FOCUS + THE_EXTENTS)is nevertriggered, so the font environment and page layout are not recalculated.
This leaves the editor in a stale state, producing the visual mismatch.
There was already a FIXME comment at this location noting that GUI focus
was not properly transferred.
Fix
Added
resume()andsend_keyboard_focus()afterset_current_view()in
kill_window(), matching the pattern already used byvar_focus_on_buffer()innew_view.cpp.Developer Doc
