Stuck loading model

[SirMaximilian]

After an update, the widget doesn't load and gets stuck saying loading widget. Is it possible to get this updated for the newer JupiterLab versions? Is it also possible to get this on the Jupyter extension Manager?

I am having the same problem. Please let me know if you find a way around.

I gave up and used ipycanvas ... found a good example that worked like a charm.

It seems that the widget is not compatible with the last version of jupyterlab. I downgraded it to 1.2.4 and it works

Hi jiver54, could you please share that ipycanvas example? I am stuck with the clickable image widget. Thank you!

I sort of put things together from https://github.com/martinRenou/ipycanvas I did find some mouse drawing examples

These are the bits of mouse code I used... It's strange that it does not seem to pass the (x,y) however it seems to get there!

sets up the layers

from ipycanvas import MultiCanvas, hold_canvas canvas = MultiCanvas(3, width=width, height=height) background_layer = canvas[0] drawing_layer = canvas[1] interaction_layer = canvas[2] ...

Functions to do stuff

def draw_line(canvas, start, end): canvas.begin_path() canvas.move_to(start[0], start[1]) canvas.line_to(end[0], end[1]) canvas.stroke() canvas.close_path()

def on_mouse_down(x, y): global drawing global start if not drawing: drawing_layer.clear() start = (x, y) TopX.value=str(int(x)) TopY.value=str(int(y)) else: with hold_canvas(canvas): draw_line(drawing_layer, start, (x, y)) BtmX.value=str(int(x)) BtmY.value=str(int(y)) interaction_layer.clear() start = None drawing = not drawing

def on_mouse_move(x, y): if not drawing: return with hold_canvas(canvas): interaction_layer.clear() draw_line(interaction_layer, start, (x, y))

sets the functions to trigger when there is mouse activity

interaction_layer.on_mouse_down(on_mouse_down) interaction_layer.on_mouse_move(on_mouse_move)
