…y styles to UINodes
- Introduced `StyleContext` class to manage UI element styles, including tag, ID, classes, and states. - Implemented methods for adding, removing, and checking classes and states within `StyleContext`. - Added functionality to synchronize `StyleContext` with associated `UINode`. - Created `Stylesheet` class to manage style rules and selectors, including parsing CSS-like rules. - Enhanced `value` class to support various data types and added factory methods for creating values from strings. - Implemented `StylesheetParser` for parsing CSS strings into style rules and properties. - Improved type safety and organization of style-related code with enums and structured classes.
- Removed the StylesheetParser.h file as it was no longer needed. - Updated value.cpp to remove an unnecessary return statement in the Hash operator. - Implemented Node class in Node.cpp and Node.hpp for XML node representation, including methods for child management, attribute handling, and searching by tag/path. - Added CSSSelectorParser class in SelectorParser.cpp and SelectorParser.hpp for parsing CSS selectors, including support for combinators and pseudo-classes. - Introduced StylesheetParser class in StylesheetParser.hpp for parsing stylesheets, including rules and declarations. - Created a test CSS file (test.css) with a basic style rule.
- Added root property to Node structure to identify root nodes. - Implemented methods in ElementData for managing ID and class attributes: - getId, setId for ID management. - getClassList, setClassList, addClass, removeClass, hasClass, toggleClass for class management. - Updated Node class to include is_root method. - Introduced ComputedStyle structure in Stylesheet for managing CSS properties. - Created DeclarationParser for parsing CSS declarations. - Implemented StyleComputer for computing styles based on stylesheets and node structure. - Enhanced StylesheetParser to support parsing of stylesheets with improved error handling.
- Consolidated layout computation logic into a single method, `compute_layout`, improving readability and maintainability. - Removed the `apply_styles_to_layout` method and integrated its functionality directly into the layout computation process. - Enhanced the handling of text layout by calculating dimensions based on font size. - Introduced a new `LayoutContext` structure to manage layout context more effectively. - Updated `LayoutBox` to simplify its structure, focusing on essential properties for layout calculations. - Improved the handling of child layout computations, allowing for better flexibility in layout direction (vertical/horizontal). - Refined style value handling in `value.cpp` and `value.h`, ensuring consistent type management and default values. - Adjusted color handling to default to transparent instead of opaque in `asColor` method.
