From d9ee2ab501089e0ee22305ae99e13c7b730bc798 Mon Sep 17 00:00:00 2001 From: Rob McDonald Date: Tue, 14 Apr 2026 09:34:03 -0700 Subject: [PATCH] gitk: add horizontal scrollbar to the commit list pane When many branches and tags decorate the same commit, the ref labels push the commit description far to the right, often out of the visible area of the left pane. The canvas widget already tracked the maximum x extent via canvxmax and updated its scrollregion accordingly, but there was no scrollbar wired up to let the user reach that content. Add a horizontal scrollbar (.tf.histframe.cxsb) below the three-pane history area, connected to the left canvas (canv) via its xscrollcommand and xview. No behaviour is changed for the author (canv2) or date (canv3) panes; they continue to scroll only vertically in lock-step as before.
