Getting the current size of a window

[rsimon]

Hi,

I want to implement responsive toolbars for my mosaic windows. Depending on how wide the current window is, the toolbarControls should either show a list of icons, or a single "more" icon that would open a dropdown. I can listen to changes in the tile arrangement via the onChange callback. But then I don't know how to get the width of the toolbar. I was hoping to be able to get a ref to the MosaicWindow. But that doesn't actually provide a handle on the HTML element.

Any recommendations how to achieve this best?
