# Objective fixes #8516 * Give `CalculatedSize` a more specific and intuitive name. * `MeasureFunc`s should only be updated when their `CalculatedSize` is modified by the systems managing their content. For example, suppose that you have a UI displaying an image using an `ImageNode`. When the window is resized, the node's `MeasureFunc` will be updated even though the dimensions of the texture contained by the node are unchanged. * Fix the `CalculatedSize` API so that it no longer requires the extra boxing and the `dyn_clone` method. ## Solution * Rename `CalculatedSize` to `ContentSize` * Only update `MeasureFunc`s on `CalculatedSize` changes. * Remove the `dyn_clone` method from `Measure` and move the `Measure` from the `ContentSize` component rather than cloning it. * Change the measure_func field of `ContentSize` to type `Option<taffy::node::MeasureFunc>`. Add a `set` method that wraps the given measure appropriately. --- ## Changelog * Renamed `CalculatedSize` to `ContentSize`. * Replaced `upsert_leaf` with a function `update_measure` that only updates the node's `MeasureFunc`. * `MeasureFunc`s are only updated when the `ContentSize` changes and not when the layout changes. * Scale factor is no longer applied to the size values passed to the `MeasureFunc`. * Remove the `ContentSize` scaling in `text_system`. * The `dyn_clone` method has been removed from the `Measure` trait. * `Measure`s are moved from the `ContentSize` component instead of cloning them. * Added `set` method to `ContentSize` that replaces the `new` function. ## Migration Guide * `CalculatedSize` has been renamed to `ContentSize`. * The `upsert_leaf` function has been removed from `UiSurface` and replaced with `update_measure` which updates the `MeasureFunc` without node insertion. * The `dyn_clone` method has been removed from the `Measure` trait. * The new function of `CalculatedSize` has been replaced with the method `set`. |
