How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.

Walkthrough

The PR updates rectangle handling, prevents null font-name reads, changes tree-view callback reference handling, applies formatting cleanup, and conditionally includes the test directory in CMake builds.

Changes

UI runtime updates

Layer / File(s) Summary
Rectangle contract and parent geometry
src/tinyui.h, src/widgets.cpp
Rect::mergeWithRect now calculates bounds before updating. Rect::isInited() reports initialization state. Parent assignment uses the first child rectangle when the parent is uninitialized.
Font and callback handling
src/tinyui.cpp, src/widgets.cpp
setDefaultFont avoids comparing a null font name. treeView no longer increments the new callback reference count. Related formatting cleanup is included.

Test build integration

Layer / File(s) Summary
Conditional test directory inclusion
CMakeLists.txt
The test subdirectory is added only when test/CMakeLists.txt exists.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 7f8a0

The change still has bounded correctness and cleanup risks: some child widgets may not receive mouse input, merged rectangles may have incorrect sizes, callbacks may remain allocated after cleanup, and font names with matching prefixes may be handled incorrectly. The PR is not merge-ready until these issues are fixed or explicitly accepted.

In `@src/tinyui.cpp`:
- Around line 207-210: Update the font-name comparison in the surrounding
style-update function to require exact equality rather than accepting names that
merely begin with defaultFont; replace the prefix-based strncmp check with
strcmp or an equivalent length-aware comparison, and add a regression test
proving a value such as “Arial.ttf.backup” does not match “Arial.ttf” and
updates mName.

In `@src/tinyui.h`:
- Around line 271-289: Update the rectangle merge logic before the set call so
x2_ and y2_ absolute bounds are converted to width and height relative to x1_
and y1_. Preserve the merged top-left coordinates and pass the resulting
dimensions to set.

In `@src/widgets.cpp`:
- Around line 129-132: Update the parent-rectangle handling around mRect so it
initializes from the first child only when uninitialized, then merges every
subsequent child rectangle via mergeWithRect. Preserve findSelectedWidget’s
ability to traverse children outside the first child’s bounds.
- Around line 444-448: Restore the initial callback reference increment in the
tree-view setup after assigning the new CallbackI to widget->mCallback, so
recursiveClear’s decRef reaches deletion during Widgets::clear; update the
commented callback->incRef logic without changing unrelated cleanup behavior.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Retain the tree-view callback until cleanup.

The CallbackI constructor used here leaves mNumRefs at zero. recursiveClear calls decRef, which does not delete a zero-reference callback. Each tree view therefore leaks its callback when Widgets::clear runs.

Restore the initial reference increment.

Proposed fix
     auto *callback = new CallbackI(onTreeViewItemClicked, nullptr, Events::MouseButtonDownEvent);
     widget->mCallback = callback;
-    /* if (callback != nullptr) {
-        callback->incRef();
-    }*/
+    callback->incRef();
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
auto *callback = new CallbackI(onTreeViewItemClicked, nullptr, Events::MouseButtonDownEvent);
widget->mCallback = callback;
if (callback != nullptr) {
/* if (callback != nullptr) {
callback->incRef();
}
}*/
auto *callback = new CallbackI(onTreeViewItemClicked, nullptr, Events::MouseButtonDownEvent);
widget->mCallback = callback;
callback->incRef();
