I want to press btn to add another geometry, but run() will block the current thread. So I didn't succeed, Do you know how to solve it, thank you very much!

I solved it by using open3d.visualization.Visualizer() instead of self.vis = o3d.visualization.VisualizerWithEditing()
VisualizerWithEditing() can only render one geometry at a time even though you succeeded in adding it whereas Visualizer can only render more than one geometry.
