能否自定义GitAhead界面布局以匹配TortoiseHg工作台？

Great question! Unfortunately, GitAhead doesn’t come with built-in options to rearrange its UI elements into exactly the TortoiseHg-style layout you’re describing—this kind of structural overhaul isn’t part of its default settings (and you already noted you’re not after just font/color tweaks). So you’ll need to modify the source code to pull this off, and since it’s built with Qt, we can break down the key areas to target:

核心源码修改步骤 #

GitAhead relies on Qt’s UI system, so most of the layout work will involve editing .ui files (created with Qt Designer) and the corresponding C++ code that manages widget behavior. Here’s how to tackle each part of your desired layout:

1. 顶部全屏分支选择+排序筛选栏 #

• First, find the main window’s UI file (look for MainWindow.ui in the source tree).
• Locate the widget holding the branch selector and filter/sort controls—right now, it’s probably tucked into a smaller container that limits its width.
• Adjust its position in the main QVBoxLayout to be the top-most element, and set its layout properties to span the full window width (remove any horizontal margins that are restricting it).
• Check the accompanying MainWindow.cpp file for any hardcoded width constraints on these controls—delete or modify lines like setFixedWidth() that would block full-width expansion.

2. 全屏历史日志置于筛选栏下方 #

• The history log lives in a widget like HistoryView or LogWidget.
• In the main window layout, place this widget directly below the branch/filter bar. Set its stretch factor to 1 (higher than other widgets) so it takes up all available vertical space except the bottom output log.
• Ensure the container around the history log doesn’t have fixed width limits—set it to expand horizontally to fill the entire window.

3. 提交详情分屏布局（左文件列表，右提交信息+变更） #

• The commit details panel is likely in CommitDetailsWidget or similar. Right now, it’s probably using a vertical layout.
• Replace that layout with a horizontal QSplitter to split the panel into two sections.
• Move the file list widget to the splitter’s left pane, and the commit info/file diff widgets to the right. You can set an initial size ratio (e.g., 30% left, 70% right) if you prefer.
• Double-check the code that populates these widgets (in the corresponding .cpp file) to make sure they don’t rely on hardcoded positions that would break the new splitter layout.

4. 底部保留输出日志 #

• The output log is typically a QTextEdit or QPlainTextEdit widget in the main window.
• Keep it at the bottom of the main layout, set a minimum or fixed height, and ensure it spans the full window width. Set its stretch factor to 0 so it doesn’t steal space from the history log above.

额外Tips避免踩坑 #

• Test incrementally: Build GitAhead after each small change to catch layout issues early—Qt’s layout system can be tricky, and widgets might not expand as expected if you miss a constraint.
• Watch for fixed sizes: Scan the code for setFixedWidth(), setMaximumWidth(), or similar calls that lock widget sizes—these are the biggest culprits for preventing full-width expansion.
• Save layout state: If you want your custom layout to persist between sessions, you’ll need to modify the settings code. Look for where GitAhead saves window state (usually in a settings file) and add code to store/restore the splitter positions and layout sizes.
