VERSION 1.85 WIP (In Progress)
VERSION 1.85 (Released 2021-10-12)
-----------------------------------------------------------------------
This is the last release officially supporting C++03 and Visual Studio 2008/2010. (#4537)
We expect that the next release will require a subset of the C++11 language (VS 2012~, GCC 4.8.1, Clang 3.3).
We may use some C++11 language features but we will not use any C++ library headers.
If you are stuck on ancient compiler you may need to stay at this version onward.
Breaking Changes:
- Removed GetWindowContentRegionWidth() function. keep inline redirection helper.
Can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead but it's not
very useful in practice, and the only use of it in the demo was illfit.
Using 'GetContentRegionAvail().x' is generally a better choice.
- (Docking branch) IsWindowFocused() and IsWindowHovered() with only the _ChildWindows flag
and without the _RootWindow flag used to leak docking hierarchy, so a docked window would
return as the child of the window hosting the dockspace. This was inconsistent and incorrect

- Nav: Fixed using SetKeyboardFocusHere() on non-visible/clipped items. It now works and will scroll
toward the item. When called during a frame where the parent window is appearing, scrolling will
aim to center the item in the window. When calling during a frame where the parent window is already
visible, scrolling will aim to scroll as little as possible to make the item visible. We will later
expose scroll functions and flags in public API to select those behaviors. (#343, #4079, #2352)

A primer on labels and the ID Stack...
Dear ImGui internally need to uniquely identify UI elements.
Dear ImGui internally needs to uniquely identify UI elements.
Elements that are typically not clickable (such as calls to the Text functions) don't need an ID.
Interactive widgets (such as calls to Button buttons) need a unique ID.
Unique ID are used internally to track active widgets and occasionally associate state to widgets.
Unique ID are implicitly built from the hash of multiple elements that identify the "path" to the UI element.
**Unique ID are used internally to track active widgets and occasionally associate state to widgets.<BR>
Unique ID are implicitly built from the hash of multiple elements that identify the "path" to the UI element.**
Since Dear ImGui 1.85 you can use `Demo>Tools>Stack Tool` or call `ImGui::ShowStackToolWindow()`. The tool display intermediate values leading to the creation of a unique ID, making things easier to debug and understand.

- Unique ID are often derived from a string label and at minimum scoped within their host window:
