问题 I am using react-konva for drawing shapes on a stage and to edit them I select that shape and the shape has be set to focus on stage(i.e come to the center of the stage). On the click of a button I am updating the X,Y and scale of the stage but I am not getting the shape exactly at the center of the stage. Please see this demo and share your inputs on this: https://codesandbox.io/s/shapecenterdemo-o9hg2?file=/src/ShapeCenterDemo.jsx PS: Can't remove the dragBoundFunc from the stage. 回答1:
