[DEBUG] This function also acts as a defacto test to make sure we can rebuild from scratch without a glitch (Different from DockSettingsHandler_ClearA

User helper to append/amend into a dock node tab bar. Most commonly used to add e.g. a "+" button.

Retrieve the drop rectangles for a given direction or for the center + perform hit testing.

window menu button == collapse button when not in a dock node. FIXME: This is similar to RenderWindowTitleBarContents(), may want to share code.

host_node may be NULL if the window doesn't have a DockNode already. FIXME-DOCK: This is misnamed since it's also doing the filtering.

Update Pos/Size for a node hierarchy (don't affect child Windows yet) (Depth-first, Pre-Order)

(Depth-First, Pre-Order)

- Remove inactive windows/nodes. - Update visibility flag.

Update CentralNode, OnlyNodeWithWindows, LastFocusedNodeID. Copy window class.

This is rarely called as DockNodeUpdateForRootNode() generally does it most frames.

Submit the tab bar corresponding to a dock node and various housekeeping details.

Default handler for g.DockNodeWindowMenuHandler(): display the list of windows for a given dock-node. This is exceptionally stored in a function point

Recreate nodes based on settings data

Clear settings data

Remove references stored in ImGuiWindowSettings to the given ImGuiDockNodeSettings

Create an explicit dockspace node within an existing window. Also expose dock node flags and creates a CentralNode by default. The Central Node is alw

Tips: Use with ImGuiDockNodeFlags_PassthruCentralNode! The limitation with this call is that your window won't have a local menu bar, but you can also

NB: You likely want to specify the ImGuiSliderFlags_AlwaysClamp when using this.

NB: v_speed is float to allow adjusting the drag speed with more precision

NB: You likely want to specify the ImGuiSliderFlags_AlwaysClamp when using this.

Note: p_data, p_min and p_max are _pointers_ to a memory address holding the data. For a Drag widget, p_min and p_max are optional. Read code of e.g.

Demonstrate creating a simple console window, with scrolling, filtering, completion and history. For the console example, we are using a more C++ like

More advanced version. Use a alternative clipping technique: fast-forwarding through non-visible chunks. - On my desktop PC (2020), for 10K nodes in a

Basic version, recursive. This is how you would generally draw a tree. - Simple but going to be noticeably costly if you have a large amount of nodes

To support node with same name we incorporate node->UID into the item ID. (this would more naturally be done using PushID(node->UID) + TreeNodeEx(node

This is normally called by Render(). You may want to call it directly if you want to avoid calling Render() but the gain will be very minimal.

Return updated ImGuiMultiSelectIO structure. Lifetime: don't hold on ImGuiMultiSelectIO* pointers over multiple frames or past any subsequent call to
