Added RenderTexture infrastructure to UIDrawable: + - `std::unique_ptr render_texture` + - `sf::Sprite render_sprite` + - `bool use_render_texture` and `bool render_dirty` flags + - `enableRenderTexture()` and `markDirty()` methods +2. Implemented clip_children property for UIFrame: + - Python property getter/setter + - Automatic RenderTexture creation when enabled + - Proper handling of nested render contexts +3. Updated UIFrame::render() to support clipping: + - Renders frame and children to RenderTexture when clipping enabled + - Handles coordinate transformations correctly + - Optimizes by only re-rendering when dirty +4. Added dirty flag propagation: + - All property setters call markDirty() + - Size changes recreate RenderTexture + - Animation system integration + +**Technical Details**: +- RenderTexture created lazily on first use +- Size matches frame dimensions, recreated on resize +- Children rendered at local coordinates (0,0) in texture +- Final texture drawn at frame's world position +- Transparent background preserves alpha blending + +**Test Results**: +- Basic clipping works correctly - children are clipped to parent bounds +- Nested clipping (frames within frames) works properly +- Dynamic resizing recreates RenderTexture as needed +- No performance regression for non-clipped frames +- Memory usage reasonable (textures only created when needed) + +**Result**: Foundation laid for advanced rendering features. UIFrame can now clip children to bounds, enabling professional UI layouts. Architecture supports future effects like blur, glow, and shaders. + +--- + +### Task: Grid Background Colors (#50) + +**Status**: Completed +**Date**: 2025-07-06 + +**Goal**: Add customizable background color to UIGrid + +**Implementation**: +1. Added `sf::Color background_color` member to UIGrid class +2. Implemented Python property getter/setter for background_color +3. Updated UIGrid::render() to clear RenderTexture with background color +4. Added animation support for individual color components: + - background_color.r, background_color.g, background_color.b, background_color.a +5. Default background color set to dark gray (8, 8, 8, 255) + +**Test Results**: +- Background color properly renders behind grid content +- Python property access works correctly +- Color animation would work with Animation system +- No performance impact + +**Result**: Quick win completed. Grids now have customizable background colors, improving visual flexibility for game developers. + +--- + ## Phase 5: Window/Scene Architecture ### Task: Window Object Singleton (#34) diff --git
