Nav: Made CTRL+TAB skip menus + skip the current navigation window if is has the ImGuiWindow_NoNavFocus set. (#787) ...

While it was previously possible, you won't be able to CTRL-TAB out and immediately back in a window with the ImGuiWindow_NoNavFocus flag.

Metrics: Changed io.MetricsActiveWindows to reflect the number of active windows (!= from visible windows), which is useful for lazy/idle render mechanisms as new windows are typically not visible for one frame. ...

Metrics: Added io.MetricsRenderWindow to reflect the number of visible windows.

Examples: OpenGL2: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications. (#1996)

Changelog for #1989

Comments

Renamed io.OptResizeWindowsFromEdges to ConfigResizeWindowsFromEdges, io.OptCursorBlink to io.ConfigCursorBlink, io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency. (#1427, #1495, #822, #473, #650) ...

Demo: Exposed flags in Demo.

Fixed PushID() from keeping alive the new ID Stack top value (if a previously active widget shared the ID it would be erroneously kept alive) (drag and drop demo could soft-lock the UI until pressing Escape!)

Drag and Drop: Added ImGuiDragDropFlags_SourceAutoExpirePayload flag to force payload to expire if the source stops being submitted. (#1725, #143).

Drag and Drop: Payload stays available and under the mouse if the source stops being submitted, however the tooltip is replaced by "..." + moved FrameScopeActive = false at the bottom of EndFrame() for safety. (#1725)

Made assertion more clear when trying to call Begin() outside of the NewFrame()..EndFrame() scope. (#1987)

Examples: OpenGL3: Tweaks, added changelog. (#1941)

CollapseButton: Added hovering highlight + minor consistency tweaks.

Fixed horizontal mouse wheel not forwarding the request to the parent window if ImGuiWindowFlags_NoScrollWithMouse is set. (#1463, #1380, #1502)

Changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.

Nav: Fixed CTRL+TAB windowing list from always showing the implicit Debug window. (#787)

Demo: Clarified the use of IsItemHovered()/IsItemActive() right after being in the "Active, Focused, Hovered & Focused Tests" section. This will be of more importance with the introduction of tabs.

Examples: Tweaked the main.cpp example structure for all examples. (There are a few hidden agendas here: 1) I would like to avoid encouraging people from using the implicit "Debug" window, and promote using Begin/End. In spite of my best attempt, there are a few feature of the upcoming docking system that cannot work 100% properly for the implicit Debug window, so future proof let's not put that feature in the spotlight too much for new users. 2) Moved dumb hardcoded positions into a single spot that can be replaced with a viewport relative position and not affect other demo windows. 3) Calling ShowDemoWindow before anything else, also for the benefit of a specific docking demo which will have an ordering constraint which is not really problematic in a real app but shouldn't be put forward in the demo.

Examples: DX10, DX11: Fixed unreleased resources in Init and Shutdown functions. (#1944)

+ shallow changelog tweaks

Examples: OpenGL3: Added shaders more versions of GLSL + made the example app default to GL 3.0 + GLSL 130 (instead of GL 3.2 + GLSL 150) unless on Mac. (#1938, #1900, #1513, #1466, etc.)

OpenGL3: Added error output when shaders fail to compile / link. (#1938)

Nav: Added a CTRL+TAB window list and changed the highlight system accordingly. (#787)
