VERSION 1.90.7 (Released 2024-05-27)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.7
Breaking changes:
- Inputs: on macOS X, Cmd and Ctrl keys are now automatically swapped by io.AddKeyEvent(),
as this naturally align with how macOS X uses those keys. (#2343, #4084, #5923, #456)
- Effectively it means that e.g. ImGuiMod_Ctrl | ImGuiKey_C is a valid idiomatic shortcut
for both Windows and Mac style users.
- It shouldn't really affect your code unless you had explicit/custom shortcut swapping in
place for macOS X apps in your input logic.
- Removed ImGuiMod_Shortcut which was previously dynamically remapping to Ctrl or Cmd/Super.
It is now unnecessary to specific cross-platform idiomatic shortcuts.
Kept symbols redirecting ImGuiMod_Shortcut to ImGuiMod_Ctrl (will obsolete).
- Commented out obsolete symbols renamed in 1.88 (May 2022):
CaptureKeyboardFromApp() -> SetNextFrameWantCaptureKeyboard()
CaptureMouseFromApp() -> SetNextFrameWantCaptureMouse()
- Backends: SDL_Renderer2/SDL_Renderer3: ImGui_ImplSDLRenderer2_RenderDrawData() and
ImGui_ImplSDLRenderer3_RenderDrawData() now takes a SDL_Renderer* parameter. This was previously
overlooked from the API but it will allow eventual support for multi-viewports.
Other changes:
- Windows: BeginChild(): fixed visibility of fully clipped child windows and tables to Test Engine.
- Windows: BeginChild(): fixed auto-fit calculation when using either (not both) ResizeX/ResizeY
and double-clicking on a border. Calculation incorrectly didn't always account for scrollbar as
it assumed the other axis would also be auto-fit. (#1710)
- Inputs: added shortcut and routing system in public API. (#456, #2637) [BETA]
- The general idea is that several callers may register interest in a shortcut, and only one owner gets it.
- in Parent: call Shortcut(Ctrl+S) // When Parent is focused, Parent gets the shortcut.
- in Child1: call Shortcut(Ctrl+S) // When Child1 is focused, Child1 gets the shortcut (Child1 overrides Parent shortcuts)
- in Child2: no call // When Child2 is focused, Parent gets the shortcut.
The whole system is order independent, so if Child1 makes its calls before Parent, results will be identical.
This is an important property as it facilitate working with foreign code or larger codebase.
- Added Shortcut() function:
e.g. Using ImGui::Shortcut(ImGuiMod_Ctrl | ImGuiKey_C); with default policy:
- checks that CTRL+C is pressed,
- and that current window is in focus stack,
- and that no other requests for CTRL+C have been made from higher priority locations
(e.g. deeper in the window/item stack).
- Added SetNextItemShortcut() to set a shortcut to locally or remotely press or activate
an item (depending on specified routing policy: using ImGuiInputFlags_RouteGlobal the item
shortcut may be executed even if its window is not in focus stack).
Items like buttons are not fully activated, in the sense that they get pressed but another
active item, e.g. InputText() won't be deactivated.
- Added routing policies for Shortcut(), SetNextItemShortcut(): (#456, #2637)
- ImGuiInputFlags_RouteFocused: focus stack route (default)
- ImGuiInputFlags_RouteActive: only route to active item
- ImGuiInputFlags_RouteGlobal: route globally, unless a focus route claim shame shortcut.
- ImGuiInputFlags_RouteAlways: no routing submission, no routing check.
- Added other shortcut/routing options: (#456, #2637)
- ImGuiInputFlags_Repeat: for use by Shortcut() and by upcoming rework of various
input functions (which are still internal for now).
- ImGuiInputFlags_Tooltip: for SetNextItemShortcut() to show a tooltip when hovering item.
- ImGuiInputFlags_RouteOverFocused: global route takes priority over focus route.
- ImGuiInputFlags_RouteOverActive: global route takes priority over active item.
- ImGuiInputFlags_RouteUnlessBgFocused: global route disabled if no imgui window focused.
- ImGuiInputFlags_RouteFromRootWindow: route evaluated from the point of view of root window rather than current window.
- Inputs: (OSX) Fixes variety of code which inconsistently required using Ctrl instead of Cmd.
- e.g. Drags/Sliders now use Cmd+Click to input a value. (#4084)
- Some shortcuts still uses Ctrl on Mac: e.g. Ctrl+Tab to switch windows. (#4828)
- Inputs: (OSX) Ctrl+Left Click alias as a Right click. (#2343) [@haldean, @ocornut]
- Inputs: Fixed ImGui::GetKeyName(ImGuiKey_None) from returning "N/A" or "None" depending
on value of IMGUI_DISABLE_OBSOLETE_KEYIO. It always returns "None".
- Nav: fixed holding Ctrl or gamepad L1 from not slowing down keyboard/gamepad tweak speed.
Broken during a refactor refactor for 1.89. Holding Shift/R1 to speed up wasn't broken.
- Tables: fixed cell background of fully clipped row overlapping with header. (#7575, #7041) [@prabuinet]
- Demo: Added "Inputs & Focus -> Shortcuts" section. (#456, #2637)
- Demo: Documents: Added shortcuts and renaming tabs/documents. (#7233)
- Examples: Win32+DX9,DX10,DX11,DX12: rework main loop to handle minimization and screen
locking without burning resources by running unthrottled code. (#2496, #3907, #6308, #7615)
- Backends: all backends + demo now call IMGUI_CHECKVERSION() to verify ABI compatibility between caller
code and compiled version of Dear ImGui. If you get an assert it most likely mean you have a build issue,
read comments near the assert. (#7568)
- Backends: Win32: undo an assert introduced in 1.90.6 which didn't allow WndProc
handler to be called before backend initialization. Because of how ::CreateWindow()
calls in WndProc this is facilitating. (#6275) [@MennoVink]
- Backends, Examples: SDL3: updates for latest SDL3 API changes. (#7580) [@kuvaus, @ocornut]
Breaking changes IF you were using imgui_internal.h versions of Shortcut() or owner-aware
versions of IsKeyPressed(), IsKeyChordPressed(), IsMouseClicked() prior to this version:
- Inputs (Internals): Renamed ImGuiKeyOwner_None to ImGuiKeyOwner_NoOwner, to make use more
explicit and reduce confusion with the fact it is a non-zero value and cannot be a default.
- Inputs (Internals): Renamed symbols global routes:
Renamed ImGuiInputFlags_RouteGlobalLow -> ImGuiInputFlags_RouteGlobal (this is the suggested global route)
Renamed ImGuiInputFlags_RouteGlobal -> ImGuiInputFlags_RouteGlobal | ImGuiInputFlags_RouteOverFocused
Renamed ImGuiInputFlags_RouteGlobalHigh -> ImGuiInputFlags_RouteGlobal | ImGuiInputFlags_RouteOverFocused | ImGuiInputFlags_RouteOverActive
- Inputs (Internals): Shortcut(), SetShortcutRouting(): swapped last two parameters order
in function signatures:
Before: Shortcut(ImGuiKeyChord key_chord, ImGuiID owner_id = 0, ImGuiInputFlags flags = 0);
After: Shortcut(ImGuiKeyChord key_chord, ImGuiInputFlags flags = 0, ImGuiID owner_id = 0);
- Inputs (Internals): owner-aware versions of IsKeyPressed(), IsKeyChordPressed(), IsMouseClicked():
swapped last two parameters order in function signatures:
Before: IsKeyPressed(ImGuiKey key, ImGuiID owner_id, ImGuiInputFlags flags = 0);
After: IsKeyPressed(ImGuiKey key, ImGuiInputFlags flags, ImGuiID owner_id = 0);
Before: IsMouseClicked(ImGuiMouseButton button, ImGuiID owner_id, ImGuiInputFlags flags = 0);
After: IsMouseClicked(ImGuiMouseButton button, ImGuiInputFlags flags, ImGuiID owner_id = 0);
- For several reasons those changes makes sense. They were all made before making some of
those API public. Only past users of imgui_internal.h with the extra parameters will be affected.
Added asserts for valid flags in various functions to detect _some_ misuses, BUT NOT ALL.
