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.

Gitk - The Git Repository Browser
Gitk is a graphical Git repository browser. It displays the commit history of a Git repository as a graph, showing the relationships between commits, branches, and tags.
Usage
To view the history of the current repository:
gitk
To view the history of specific files or directories:
gitk path/to/file
gitk path/to/directory
To view a specific branch or range of commits:
gitk branch-name
gitk v1.0..v2.0
For more usage examples and options, see the gitk manual.
Building
Gitk is a Tcl/Tk application. It requires Tcl/Tk to be installed on your system.
Running directly
Gitk can be run from the source directory without installation:
./gitk
This allows for quick testing of changes.
Installation
To install system-wide, you can use either make or meson:
# Install to default location ($HOME/bin)
make install
# Install to system-wide location
sudo make install prefix=/usr/local
# Install to custom location
make install prefix=/opt/gitk
# Using Meson
meson setup builddir
meson compile -C builddir
meson install -C builddir
Both build systems will handle setting the correct Tcl/Tk interpreter path and installing translation files.
Contributing
Contributions are welcome! The preferred method for submitting patches is via email to the Git mailing list, as this allows for more thorough review and broader community feedback. However, GitHub pull requests are also accepted.
All commits must be signed off (use git commit --signoff) and should
have commit messages prefixed with gitk:.
