Transparent background?

[yueqiw]

Hi,

The package is great for shiny apps. I'm wondering if it's possible to use transparent background so that the previous plots won't disappear entirely? Thanks!

The problem is not the background-color. The problem is, that when the spinner shows, the underlying ouput visibility is set to hidden.

To undo this you have to change the spinner.js code.
Uncomment line 4 (below) and you get what you want:
$(".recalculating").siblings(".load-container").siblings('.shiny-bound-output, .shiny-output-error').css('visibility', 'hidden');

A working example can be found by Gao Zheng at Pill-GZ@358c007

It doesn't work perfectly well with datatables, for which the height of the table is not known at the time withspinner is called, and so is estimated. The problem is that, when/if the table is changed, the 'estimated' height is placed, as blank space, above the table.

In that case, I found I need to set proxy.height to zero. The 'spinner' ends up appearing at the top of where the table will appear.

I've added a hide.ui parameter to support this.
