How do I redraw UI using Slate?

Hi everyone,

I feel like this is a very simple question but I haven’t been able to find the answer in days.

I am writing the UI code for a plugin I’m making using Slate. When a button is pressed, I want the layout to change. However, I don’t know what function to call to redraw/repaint/update the layout.

Here’s the previous, more verbose question I asked for anyone interested, though it went unanswered.

Any help would be greatly, greatly appreciated.
