widget

问题 In R, using the rgl and htmlwidgets libraries, I'm trying to extract an HTML file having a widget with toggle buttons . The following example does what I want in the RStudio Viewer.

This will allow you to use Link controls for each button. The small widget style only allows you to set the

I want the ListView's crossAxis(vertical direction) to take up the ListView's Item height (only wrapping the content), but it is taking up the entire screen height.

问题 I was just wondering, if there's some way how to automatically save the content of the cell (including the cell output) to a PNG/PDF/JPG/GIF. I'd be happy with any of the alternatives. For documentation purposes I'd like to save the state of a VBox/Hbox containing multiple iPython Widgets.
