From 96dd299055a1ce35819480f3c4b938f8e6f91537 Mon Sep 17 00:00:00 2001 From: Hans Goudey Date: Tue, 13 Oct 2020 12:43:28 -0500 Subject: UI: Add highlight arguments to tab buttons This adds arguments to `uiLayout.prop_tabs_enum` and the C equivalent (`uiItemTabsEnumR_prop`) to gray out tabs based on a boolean array. For property search in multiple tabs, we need a way to show which tabs have a search result, but we still need to show which tab is active.
