@@ -76,6 +76,10 @@ Breaking Changes:
- Access to full key ranges will allow us to develop a proper keyboard shortcut system. (#456)
- io.AddKeyEvent() will later be turned into a trickling IO queue (for all inputs) to handle very low framerate better. (#2525, #2787, #3383)
- io.SetKeyEventNativeData() include native keycode/scancode which will later be exposed. (#3141, #2959)
- Reworked IO nav/gamepad input API and unifying inputs sources: (#4858, #787)
- Added full range of ImGuiKey_GamepadXXXX enums (e.g. ImGuiKey_GamepadDpadUp, ImGuiKey_GamepadR2) to use with
io.AddKeyEvent(), io.AddKeyAnalogEvent().
- Added io.AddKeyAnalogEvent() function, obsoleting writing directly to io.NavInputs[] arrays.
- Renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum. (#2625)
- Backends: GLFW: backend now uses glfwSetCursorPosCallback().
- If calling ImGui_ImplGlfw_InitXXX with install_callbacks=true: nothing to do. is already done for you.
@@ -101,6 +105,8 @@ Other Changes:
- IO: Added event based input queue API, which now trickles events to support low framerates. [@thedmd, @ocornut]
Previously the most common issue case (button presses in low framerates) was handled by backend. This is now
handled by core automatically for all kind of inputs. (#4858, #2787, #1992, #3383, #2525, #1320)
- New IO functions for keyboard/gamepad: AddKeyEvent(), AddKeyAnalogEvent(), AddKeyModsEvent().
- New IO functions for mouse: AddMousePosEvent(), AddMouseButtonEvent(), AddMouseWheelEvent().
- Fixed a situation where CTRL+Tab or Modal can occasionally lead to the creation of ImDrawCmd with zero triangles,
which would makes the draw operation of some backends assert (e.g. Metal with debugging). (#4857)
- Popups: Fixed a regression crash when a new window is created after a modal on the same frame. (#4920) [@rokups]

- You can ask questions and report issues at https://github.com/ocornut/imgui/issues/787
- The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable.
- Keyboard:
- Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable.
NewFrame() will automatically fill io.NavInputs[] based on your io.AddKeyEvent() calls.
- When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), the io.WantCaptureKeyboard flag
will be set. For more advanced uses, you may want to read from:
- Application: Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable.
- Internally: NewFrame() will automatically fill io.NavInputs[] based on backend's io.AddKeyEvent() calls.
- When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard),
the io.WantCaptureKeyboard flag will be set. For more advanced uses, you may want to read from:
- io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set.
- io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used).
- or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions.
Please reach out if you think the game vs navigation input sharing could be improved.
- Gamepad:
- Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable.
- Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame().
Note that io.NavInputs[] is cleared by EndFrame().
- See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. For each entry of io.NavInputs[], set the following values:
0.0f= not held. 1.0f= fully held. Pass intermediate 0.0f..1.0f values for analog triggers/sticks.
- We use a simple >0.0f test for activation testing, and won't attempt to test for a dead-zone.
Your code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).
- Application: Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable.
- Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + call io.AddKeyEvent/AddKeyAnalogEvent() with ImGuiKey_Gamepad_XXX keys.
For analog values (0.0f to 1.0f), backend is responsible to handling a dead-zone and rescaling inputs accordingly.
Backend code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).
- Internally: NewFrame() will automatically fill io.NavInputs[] based on backend's io.AddKeyEvent() + io.AddKeyAnalogEvent() calls.
- BEFORE 1.87, BACKENDS USED TO WRITE DIRECTLY TO io.NavInputs[]. This is going to be obsoleted in the future. Please call io functions instead!
- You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://dearimgui.org/controls_sheets
- If you need to share inputs between your game and the imgui parts, the easiest approach is to go all-or-nothing, with a buttons combo
to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved.
- If you need to share inputs between your game and the Dear ImGui interface, the easiest approach is to go all-or-nothing,
with a buttons combo to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved.
- Mouse:
- PS4 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback.
- PS4/PS5 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback.
- Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard.
- On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag.
Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements.

- 2022/01/20 (1.87) - inputs: reworded gamepad IO.
- Backend writing to io.NavInputs[] -> backend should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values.
- 2022/01/19 (1.87) - sliders, drags: removed support for legacy arithmetic operators (+,+-,*,/) when inputing text. This doesn't break any api/code but a feature that used to be accessible by end-users (which seemingly no one used).
- 2022/01/17 (1.87) - inputs: reworked mouse IO.
- Backend writing to io.MousePos -> backend should call io.AddMousePosEvent()
