WHEN TO UPDATE?
|

|

It is generally safe to sync to the latest commit in master. The library is fairly stable and regressions tends to be fixed fast when reported.

Keeping your copy of dear imgui updated once in a while is recommended.

|

- If you have a problem with a missing function/symbols, search for its name in the code, there will likely be a comment about it.
|
||||
- If you are dropping this repository in your codebase, please leave the demo and text files in there, they will be useful.
|
||||
- You may diff your previous Changelog with the one you just copied and read that diff.
|
||||
- You may enable `IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in imconfig.h to forcefully disable legacy names and symbols. Doing it every once in a while is a good way to make sure you are not using obsolete symbols. Dear ImGui is in active development API updates have a little more frequent lately. They are carefully documented and should not affect all users.

|
||||
- nav: SetItemDefaultFocus() level of priority, so widget like Selectable when inside a popup could claim a low-priority default focus on the first selected iem
|
||||
- nav: allow input system to be be more tolerant of io.DeltaTime=0.0f
|
||||
- nav: ESC within a menu of a child window seems to exit the child window.
|
||||
- nav: ESC on a flattened child
|
||||
- nav: NavFlattened: ESC on a flattened child should select something.
|
||||
- nav: NavFlattened: broken: in typical usage scenario, the items of a fully clipped child are currently not considered to enter into a NavFlattened child.
|
||||
- nav: NavFlattened: init request doesn't select items that are part of a NavFlattened child
|
||||
- nav: NavFlattened: cannot access menubar of a flattened child window with Alt/menu key (not a very common use case..).
|
||||
- nav: Left within a tree node block as a fallback (ImGuiTreeNodeFlags_NavLeftJumpsBackHere by default?)
|
||||
- nav: menus: pressing left-right on a vertically clipped menu bar tends to jump to the collapse/close buttons.
|
||||
- nav: menus: allow pressing Menu to leave a sub-menu.
|
||||
- nav: simulate right-click or context activation? (SHIFT+F10)
|
||||
- nav: tabs should go through most/all widgets (in submission order?).
|
||||
- nav: when CTRL-Tab/windowing is active, the HoveredWindow detection doesn't take account of the window display re-ordering.
|
||||
- nav: cannot access menubar of a flattened child window with Alt/menu key (not a very common use case..).
|
||||
- nav: esc/enter default behavior for popups, e.g. be able to mark an "ok" or "cancel" button that would get triggered by those keys.
|
||||
- nav: when activating a button that changes label (without a static ID) or disappear, can we somehow automatically recover into a nearest highlight item?
|
||||
- nav: there's currently no way to completely clear focus with the keyboard. depending on patterns used by the application to dispatch inputs, it may be desirable.
