Introduce Drawing Tools Concept, Pencil and Actor The uix.Canvas widget now maintains a selected Tool which configures how the mouse interacts with the (editable) Canvas widget. The default Tool is the PencilTool and implements the old behavior: it draws pixels when clicked and dragged based on your currently selected Color Swatch. This tool automatically becomes active when you toggle the Palette tab in the editor mode. A new Tool is the ActorTool which becomes active when you select the Doodads tab. In the ActorTool you can't draw pixels on the level, but when you mouse over a Doodad instance (Actor) in your level, you may pick it up and drag it someplace else. Left-click an Actor to pick it up and drag it somewhere else. Right-click to delete it completely. You can also delete an Actor by dragging it OFF of the Canvas, like back onto the palette drawer or onto the menu bar. 2018-10-21 00:08:20 +00:00			`package uix`
