### Change selection color based on shape condition This PR adds a new example called "Selection Color Condition" that demonstrates how to dynamically change the selection color based on the types of shapes currently selected. When all selected shapes are rectangles, the selection color will turn red. Otherwise, it will revert to the default blue. This is achieved by: 1. Using `editor.react` to listen for selection changes. 2. Checking if all `editor.getSelectedShapes()` are of type 'geo' and 'rectangle'. 3. Adding/removing a CSS class (`rectangle-selection`) to the editor container. 4. Overriding `--color-selection` and `--color-selection-stroke` CSS variables in `selection-color-condition.css`. The example includes comprehensive documentation in its `README.md` on how to customize the condition for other shape types (e.g., circles, text, or mixed selections). ### Change type - [ ] `bugfix` - [ ] `improvement` - [x] `feature` - [ ] `api` - [ ] `other` ### Test plan 1. Navigate to the "Selection Color Condition" example. 2. Create several rectangle shapes. 3. Select only rectangles: Observe the selection outline and fill turn red. 4. Create other shapes (e.g., circles, text). 5. Select a mix of rectangles and other shapes: Observe the selection color remain default (blue). 6. Select only non-rectangle shapes: Observe the selection color remain default (blue). - [ ] Unit tests - [ ] End to end tests ### Release notes - Added a new example demonstrating how to dynamically change the selection color based on selected shape types. --- <a href="https://cursor.com/background-agent?bcId=bc-3355ce7f-6cb4-4da0-9366-382314cc5a9d"> <picture> <source media="(prefers-color-scheme: dark)" srcset="https://cursor.com/open-in-cursor-dark.svg"> <source media="(prefers-color-scheme: light)" srcset="https://cursor.com/open-in-cursor-light.svg"> <img alt="Open in Cursor" src="https://cursor.com/open-in-cursor.svg"> </picture> </a> <a href="https://cursor.com/agents?id=bc-3355ce7f-6cb4-4da0-9366-382314cc5a9d"> <picture> <source media="(prefers-color-scheme: dark)" srcset="https://cursor.com/open-in-web-dark.svg"> <source media="(prefers-color-scheme: light)" srcset="https://cursor.com/open-in-web-light.svg"> <img alt="Open in Web" src="https://cursor.com/open-in-web.svg"> </picture> </a> --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: alex <alex@tldraw.com>
