@ -70,6 +70,8 @@ Other changes:
- Tooltips: made using SetItemTooltip()/IsItemHovered(ImGuiHoveredFlags_ForTooltip) defaults to
activate tooltips on disabled items. This is done by adding ImGuiHoveredFlags_AllowWhenDisabled
to the default value of style.HoverFlagsForTooltipMouse/HoverFlagsForTooltipNav. (#1485)
- Tooltips: made is possible to combine ImGuiHoveredFlags_ForTooltip with a ImGuiHoveredFlags_DelayXXX
override. (#1485)
- Nav: Tabbing always enable nav highlight when ImGuiConfigFlags_NavEnableKeyboard is set.
Previously was inconsistent and only enabled when stepping through a non-input item.
