FIXME: Remove the == 0.0f behavior?

Push a given id value ignoring the ID stack as a seed.

FIXME: This may incur a round-trip (if the end user got their data from a float4) but eventually we aim to store the in-flight colors as ImU32

We don't use g.FontSize because the window may be != g.CurrentWindow.

Deferred removal, avoiding issue with changing vector while iterating it

Prepare the data for rendering so you can call GetDrawData() (As with anything within the ImGui:: namspace this doesn't touch your GPU or graphics API

Render an arrow aimed to be aligned with text (p_min is a position in the same space text would be positioned). To e.g. denote expanded/collapsed stat

Render an arrow. 'pos' is position of the arrow tip. half_sz.x is length from base to tip. half_sz.y is length on each side.

Helper for ColorPicker4() NB: This is rather brittle and will show artifact when rounding this enabled if rounded corners overlap multiple cells. Call

FIXME: Cleanup and move code to ImDrawList.

Default clip_rect uses (pos_min,pos_max) Handle clipping on CPU immediately (vs typically let the GPU clip the triangles that are overlapping the clip

Another overly complex function until we reorganize everything into a nice all-in-one helper. This is made more complex because we have dissociated th

Tip: pass a non-visible label (e.g. "##hello") then you can use the space to draw other text or image. But you need to make sure the ID is unique, e.g

Horizontal/vertical separating line FIXME: Surprisingly, this seemingly simple widget is adjacent to MANY different legacy/tricky layout issues.

FIXME: It might be undesirable that this will likely disable KeyOwner-aware shortcuts systems. Consider a more fine-tuned version for the two users of

Initialize/override default color options

Important: this alone doesn't alter current ImDrawList state. This is called by PushFont/PopFont only.

Use 'cond' to choose to submit payload on drag start or every frame

Allow last item to be overlapped by a subsequent item. Both may be activated during the same frame before the later one takes priority. FIXME: Althoug

This is more or less equivalent to: if (IsItemHovered() || IsItemActive()) SetKeyOwner(key, GetItemID()); Extensive uses of that (e.g. many calls for

_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!
