rb-lab / canvas-tree Goto Github PK

There are bugs with symlinks both in Babel-loader (see: babel/babel-loader#166) and in Webpack (see: webpack/webpack#784). And when you are using both things became messy. So I can't figure out still how to develop canvas-tree using standard npm link way...

1. draw a big rectangle with onDrag handler
2. zoom out
3. grab the rectangle by it's rightmost point
4. move it

rectangle will jump left with distance equal of it's initial (non-zoomed) size.

1. add some figures
2. zoom out (or in) significantly
3. pan canvas

speed of canvas moving is differ from pointer speed

1. it is not necessary that you want to get top-left instead of actual x-y.
2. the cursor styles should be available for dragging objects.
3. or maybe that should be not a 'drag' handler

if object have not handler for specific event type, that event should (?) bobble up, till it rich object with handler or canvas itself.
