region:show() on blizzard frame - problem
 

Consider:

This script obviously works fine after you've opened the macro frame once before.

The problem is that initialization. On a fresh reload, the same code generates an error: MacroFrame is nil.

How can I open the macro frame once from my code so that show() and hide() will work on the frame?

I'm sure that this is a commonly known dynamic, and I truly did search the forum for a solution. A search for show() returned 16 pages. I went through them and found no help. I apologize if this is an abuse of forum participant's time, but any reply would be appreciated.

Here is the list of default WoW addons: https://github.com/tekkub/wow-ui-sou...ee/live/AddOns. As you see in .toc file, Blizzard_MacroUI is LoadOnDemand addon. That means MacroFrame is created on demand. You can load it manually or use ShowMacroFrame() function.

Perfect. This actually explains A lot. TYVM.
