How does VisualizerWithEditing bound a KeyCallback?

[MikoyChinese]

Hi, guys

I try to get the picked point value from VisualizerWithEditing, But when I want to add a label name to the point I just picked, the process is blocked, I can't do anything until I quit the window. But I just want to picked a point and label it, not to label a point list.

And I found the class VisualizerWithKeyCallback, which has keycallback function but no get_picked_point. So how can I bound a keycallback for VisualizerWithEditing and do something I want? Anybody help? Thanks.

Best,
Mikoy Chinese

As far as I can see, this is a current limitation because VisualizerWithKeyCallback and VisualizerWithEditing are independent subclasses of Visualizer.

There is another issue that "it seems strange to have a separate class for a visualizer which has a keyboard callback" #737 (comment)

In my fork of open3d, I have keyboard callback features directly implemented as part of the base Visualizer class. This way, even VisualizerWithEditing has keyboard callback features, and there is no need for a separate VisualizerWithKeyCallback.

I'll raise a pull request with my changes for discussion. Stay tuned.
