Exposed in case user may want to override setting density. IMPORTANT: Begin()/End() is overriding density. Be considerate of this you change it.

FIXME-OBSOLETE: May need to obsolete/cleanup those helpers.

This is more or less equivalent to a fancier version of: if (IsItemHovered() || IsItemActive()) SetKeyOwner(key, GetItemID()); Extensive uses of that

Shortcut to use 'style.HoverFlagsForTooltipMouse' or 'style.HoverFlagsForTooltipNav'. Defaults to == ImGuiHoveredFlags_Stationary | ImGuiHoveredFlags_

_LockXXX flags are useful to lock keys away from code which is not input-owner aware. When using _LockXXX flags, you can use ImGuiKeyOwner_Any to lock

Note: this will likely be called ActivateItem() once we rework our Focus/Activation system! But ActivateItem() should function without altering scroll

This is also inlined in ItemAdd() Note: if ImGuiItemStatusFlags_HasDisplayRect is set, user needs to set g.LastItemData.DisplayRect.

This is experimental and meant to be a toy for exploring a future/wider range of features.

For each axis: - Use 0.0f as min or FLT_MAX as max if you don't want limits, e.g. size_min = (500.0f, 0.0f), size_max = (FLT_MAX, FLT_MAX) sets a mini

This function is merely here to free heap allocations.

For 32-bit and larger types, slider bounds are limited to half the natural type range. So e.g. an integer Slider between INT_MAX-10 and INT_MAX will f

Note: p_data, p_min and p_max are _pointers_ to a memory address holding the data. For a slider, they are all required. Read code of e.g. SliderFloat(
