# zgui v0.9.4 - dear imgui bindings
|
||||
|
||||
Easy to use, hand-crafted API with default arguments, named parameters and Zig style text formatting. For a test application please see [here](https://github.com/michal-z/zig-gamedev/tree/main/samples/gui_test_wgpu).
|
||||
|
||||
## Features
|
||||
|
||||
* Most public dear imgui API exposed
|
||||
* All memory allocations go through user provided Zig allocator
|
||||
* [DrawList API](#drawlist-api) for vector graphics, text rendering and custom widgets
|
||||
* [Plot API](#plot-api) for advanced data visualizations
|
||||
|
||||
## Getting started
|
||||
|
||||
Copy `zgui` folder to a `libs` subdirectory of the root of your project.
|
||||
|
||||
To get glfw/wgpu rendering backend working also copy `zgpu`, `zglfw` and `zpool` folders (see [zgpu](https://github.com/michal-z/zig-gamedev/tree/main/libs/zgpu) for the details). Alternatively, you can provide your own rendering backend, see: [backend_glfw_wgpu.zig](src/backend_glfw_wgpu.zig) for an example.
|
||||
|
||||
Then in your `build.zig` add:
|
||||
```zig
|
||||
const zgui = @import("libs/zgui/build.zig");
|
||||
|
||||
// Needed for glfw/wgpu rendering backend
|
||||
const zglfw = @import("libs/zglfw/build.zig");
|
||||
const zgpu = @import("libs/zgpu/build.zig");
|
||||
const zpool = @import("libs/zpool/build.zig");
|
||||
|
||||
pub fn build(b: *std.build.Builder) void {
|
||||
...
|
||||
const zgui_options = zgui.BuildOptionsStep.init(b, .{ .backend = .glfw_wgpu });
|
||||
const zgui_pkg = zgui.getPkg(&.{zgui_options.getPkg()});
|
||||
|
||||
exe.addPackage(zgui_pkg);
|
||||
|
||||
zgui.link(exe, zgui_options);
|
||||
|
||||
// Needed for glfw/wgpu rendering backend
|
||||
const zgpu_options = zgpu.BuildOptionsStep.init(b, .{});
|
||||
const zgpu_pkg = zgpu.getPkg(&.{ zgpu_options.getPkg(), zpool.pkg, zglfw.pkg });
|
||||
|
||||
exe.addPackage(zglfw.pkg);
|
||||
exe.addPackage(zgpu_pkg);
|
||||
|
||||
zglfw.link(exe);
|
||||
zgpu.link(exe, zgpu_options);
|
||||
}
|
||||
```
|
||||
Now in your code you may import and use `zgui`:
|
||||
```zig
|
||||
const zgui = @import("zgui");
|
||||
|
||||
zgui.init(allocator);
|
||||
|
||||
_ = zgui.io.addFontFromFile(content_dir ++ "Roboto-Medium.ttf", 16.0);
|
||||
|
||||
zgui.backend.init(
|
||||
window,
|
||||
demo.gctx.device,
|
||||
@enumToInt(swapchain_format),
|
||||
);
|
||||
```
|
||||
|
||||
```zig
|
||||
// Main loop
|
||||
while (...) {
|
||||
zgui.backend.newFrame(framebuffer_width, framebuffer_height);
|
||||
|
||||
zgui.bulletText(
|
||||
"Average : {d:.3} ms/frame ({d:.1} fps)",
|
||||
.{ demo.gctx.stats.average_cpu_time, demo.gctx.stats.fps },
|
||||
);
|
||||
zgui.bulletText("W, A, S, D : move camera", .{});
|
||||
zgui.spacing();
|
||||
|
||||
if (zgui.button("Setup Scene", .{})) {
|
||||
// Button pressed.
|
||||
}
|
||||
|
||||
if (zgui.dragFloat("Drag 1", .{ .v = &value0 })) {
|
||||
// value0 has changed
|
||||
}
|
||||
|
||||
if (zgui.dragFloat("Drag 2", .{ .v = &value0, .min = -1.0, .max = 1.0 })) {
|
||||
// value1 has changed
|
||||
}
|
||||
|
||||
// Setup wgpu render pass here
|
||||
|
||||
zgui.backend.draw(pass);
|
||||
}
|
||||
```
|
||||
|
||||
### DrawList API
|
||||
|
||||
```zig
|
||||
draw_list.addQuad(.{
|
||||
.p1 = .{ 170, 420 },
|
||||
.p2 = .{ 270, 420 },
|
||||
.p3 = .{ 220, 520 },
|
||||
.p4 = .{ 120, 520 },
|
||||
.col = 0xff_00_00_ff,
|
||||
.thickness = 3.0,
|
||||
});
|
||||
draw_list.addText(.{ 130, 130 }, 0xff_00_00_ff, "The number is: {}", .{7});
|
||||
draw_list.addCircleFilled(.{ .p = .{ 200, 600 }, .r = 50, .col = 0xff_ff_ff_ff });
|
||||
draw_list.addCircle(.{ .p = .{ 200, 600 }, .r = 30, .col = 0xff_00_00_ff, .thickness = 11 });
|
||||
draw_list.addPolyline(
|
||||
&.{ .{ 100, 700 }, .{ 200, 600 }, .{ 300, 700 }, .{ 400, 600 } },
|
||||
.{ .col = 0xff_00_aa_11, .thickness = 7 },
|
||||
);
|
||||
```
|
||||
### Plot API
|
||||
```zig
|
||||
if (zgui.plot.beginPlot("Line Plot", .{ .h = -1.0 })) {
|
||||
zgui.plot.setupAxis(.x1, .{ .label = "xaxis" });
|
||||
zgui.plot.setupAxisLimits(.x1, .{ .min = 0, .max = 5 });
|
||||
zgui.plot.setupLegend(.{ .south = true, .west = true }, .{});
|
||||
zgui.plot.setupFinish();
|
||||
zgui.plot.plotLineValues("y data", i32, .{ .v = &.{ 0, 1, 0, 1, 0, 1 } });
|
||||
zgui.plot.plotLine("xy data", f32, .{
|
||||
.xv = &.{ 0.1, 0.2, 0.5, 2.5 },
|
||||
.yv = &.{ 0.1, 0.3, 0.5, 0.9 },
|
||||
});
|
||||
zgui.plot.endPlot();
|
||||
}
|
||||

// dear imgui: Renderer Backend for DirectX12
|
||||
// This needs to be used along with a Platform Backend (e.g. Win32)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'D3D12_GPU_DESCRIPTOR_HANDLE' as ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.
|
||||
|
||||
// Important: to compile on 32-bit systems, this backend requires code to be compiled with '#define ImTextureID ImU64'.
|
||||
// This is because we need ImTextureID to carry a 64-bit value and by default ImTextureID is defined as void*.
|
||||
// To build this on 32-bit systems:
|
||||
// - [Solution 1] IDE/msbuild: in "Properties/C++/Preprocessor Definitions" add 'ImTextureID=ImU64' (this is what we do in the 'example_win32_direct12/example_win32_direct12.vcxproj' project file)
|
||||
// - [Solution 2] IDE/msbuild: in "Properties/C++/Preprocessor Definitions" add 'IMGUI_USER_CONFIG="my_imgui_config.h"' and inside 'my_imgui_config.h' add '#define ImTextureID ImU64' and as many other options as you like.
|
||||
// - [Solution 3] IDE/msbuild: edit imconfig.h and add '#define ImTextureID ImU64' (prefer solution 2 to create your own config file!)
|
||||
// - [Solution 4] command-line: add '/D ImTextureID=ImU64' to your cl.exe command-line (this is what we do in the example_win32_direct12/build_win32.bat file)
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
|
||||
// Read online: https://github.com/ocornut/imgui/tree/master/docs
|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-05-19: DirectX12: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-02-18: DirectX12: Change blending equation to preserve alpha in output buffer.
|
||||
// 2021-01-11: DirectX12: Improve Windows 7 compatibility (for D3D12On7) by loading d3d12.dll dynamically.
|
||||
// 2020-09-16: DirectX12: Avoid rendering calls with zero-sized scissor rectangle since it generates a validation layer warning.
|
||||
// 2020-09-08: DirectX12: Clarified support for building on 32-bit systems by redefining ImTextureID.
|
||||
// 2019-10-18: DirectX12: *BREAKING CHANGE* Added extra ID3D12DescriptorHeap parameter to ImGui_ImplDX12_Init() function.
|
||||
// 2019-05-29: DirectX12: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX12: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2019-03-29: Misc: Various minor tidying up.
|
||||
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-06-12: DirectX12: Moved the ID3D12GraphicsCommandList* parameter from NewFrame() to RenderDrawData().
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_dx12.cpp/.h away from the old combined DX12+Win32 example.
|
||||
// 2018-06-08: DirectX12: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle (to ease support for future multi-viewport).
|
||||
// 2018-02-22: Merged into master with all Win32 code synchronized to other examples.

|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|
||||
// 2022-09-01: Inputs: Honor GLFW_CURSOR_DISABLED by not setting mouse position.
|
||||
// 2022-04-30: Inputs: Fixed ImGui_ImplGlfw_TranslateUntranslatedKey() for lower case letters on OSX.
|
||||
// 2022-03-23: Inputs: Fixed a regression in 1.87 which resulted in keyboard modifiers events being reported incorrectly on Linux/X11.
|
||||
// 2022-02-07: Added ImGui_ImplGlfw_InstallCallbacks()/ImGui_ImplGlfw_RestoreCallbacks() helpers to facilitate user installing callbacks after initializing backend.
|
||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago)with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
||||
// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
|
||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
||||
// 2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
|
||||
// 2022-01-12: *BREAKING CHANGE*: Now using glfwSetCursorPosCallback(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetCursorPosCallback() and forward it to the backend via ImGui_ImplGlfw_CursorPosCallback().
|
||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
||||
// 2022-01-05: Inputs: Converting GLFW untranslated keycodes back to translated keycodes (in the ImGui_ImplGlfw_KeyCallback() function) in order to match the behavior of every other backend, and facilitate the use of GLFW with lettered-shortcuts API.

// 2021-07-29: *BREAKING CHANGE*: Now using glfwSetCursorEnterCallback(). MousePos is correctly reported when the host platform window is hovered but not focused. If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() callback and forward it to the backend via ImGui_ImplGlfw_CursorEnterCallback().
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
|
||||
// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
|
||||
// 2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
|
||||
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
|
||||
// 2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
|
||||
// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
|
||||
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
|
||||
// 2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
|
||||
// 2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
|
||||
// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_glfw.cpp/.h away from the old combined GLFW+OpenGL/Vulkan examples.
|
||||
// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
|
||||
// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value, passed to glfwSetCursor()).
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
|
||||
// 2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
|
||||
// 2018-01-25: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
|
||||
// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
|
||||
// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
|
||||
// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
|
||||
// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'nullptr' as per our switch to C++11.
|
||||
// 2021-11-29: Passing explicit buffer sizes to wgpuRenderPassEncoderSetVertexBuffer()/wgpuRenderPassEncoderSetIndexBuffer().
|
||||
// 2021-08-24: Fix for latest specs.
|
||||
// 2021-05-24: Add support for draw_data->FramebufferScale.
|
||||
// 2021-05-19: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-05-16: Update to latest WebGPU specs (compatible with Emscripten 2.0.20 and Chrome Canary 92).
|
||||
// 2021-02-18: Change blending equation to preserve alpha in output buffer.
|
||||
// 2021-01-28: Initial version.

// dear imgui: Platform Backend for Windows (standard windows API for 32-bits AND 64-bits applications)
|
||||
// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Platform: Clipboard support (for Win32 this is actually part of core dear imgui)
|
||||
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy VK_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
||||
// [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|
||||
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.

// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|

// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
||||
// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
|
||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
||||
// 2022-01-17: Inputs: always update key mods next and before a key event (not in NewFrame) to fix input queue with very low framerates.
|
||||
// 2022-01-12: Inputs: Update mouse inputs using WM_MOUSEMOVE/WM_MOUSELEAVE + fallback to provide it when focused but not hovered/captured. More standard and will allow us to pass it to future input queue API.
|
||||
// 2022-01-12: Inputs: Maintain our own copy of MouseButtonsDown mask instead of using ImGui::IsAnyMouseDown() which will be obsoleted.
|
||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
||||
// 2021-12-16: Inputs: Fill VK_LCONTROL/VK_RCONTROL/VK_LSHIFT/VK_RSHIFT/VK_LMENU/VK_RMENU for completeness.
|
||||
// 2021-08-17: Calling io.AddFocusEvent() on WM_SETFOCUS/WM_KILLFOCUS messages.
|

// 2021-08-02: Inputs: Fixed keyboard modifiers being reported when host window doesn't have focus.
|
||||
// 2021-07-29: Inputs: MousePos is correctly reported when the host platform window is hovered but not focused (using TrackMouseEvent() to receive WM_MOUSELEAVE events).
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-06-08: Fixed ImGui_ImplWin32_EnableDpiAwareness() and ImGui_ImplWin32_GetDpiScaleForMonitor() to handle Windows 8.1/10 features without a manifest (per-monitor DPI, and properly calls SetProcessDpiAwareness() on 8.1).
|
||||
// 2021-03-23: Inputs: Clearing keyboard down array when losing focus (WM_KILLFOCUS).
|
||||
// 2021-02-18: Added ImGui_ImplWin32_EnableAlphaCompositing(). Non Visual Studio users will need to link with dwmapi.lib (MinGW/gcc: use -ldwmapi).
|
||||
// 2021-02-17: Fixed ImGui_ImplWin32_EnableDpiAwareness() attempting to get SetProcessDpiAwareness from shcore.dll on Windows 8 whereas it is only supported on Windows 8.1.

||||
// 2021-01-25: Inputs: Dynamically loading XInput DLL.

// 2020-02-17: Added ImGui_ImplWin32_EnableDpiAwareness(), ImGui_ImplWin32_GetDpiScaleForHwnd(), ImGui_ImplWin32_GetDpiScaleForMonitor() helper functions.
|
||||
// 2020-01-14: Inputs: Added support for #define IMGUI_IMPL_WIN32_DISABLE_GAMEPAD/IMGUI_IMPL_WIN32_DISABLE_LINKING_XINPUT.
|
||||
// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
|
||||
// 2019-05-11: Inputs: Don't filter value from WM_CHAR before calling AddInputCharacter().
|
||||
// 2019-01-17: Misc: Using GetForegroundWindow()+IsChild() instead of GetActiveWindow() to be compatible with windows created in a different thread or parent.
|
||||
// 2019-01-17: Inputs: Added support for mouse buttons 4 and 5 via WM_XBUTTON* messages.
|
||||
// 2019-01-15: Inputs: Added support for XInput gamepads (if ImGuiConfigFlags_NavEnableGamepad is set by user application).

|
||||
// 2018-06-10: Inputs: Fixed handling of mouse wheel messages to support fine position messages (typically sent by track-pads).
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_win32.cpp/.h away from the old combined DX9/DX10/DX11/DX12 examples.
|
||||
// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.
|
||||
// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
|
||||
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
|
||||
// 2018-02-06: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
|

|

// stb_rect_pack.h - v1.01 - public domain - rectangle packing
|
||||
// Sean Barrett 2014
|
||||
//
|
||||
// Useful for e.g. packing rectangular textures into an atlas.
|

// Does not do rotation.
|

//
|

// Before #including,
|
||||
//
|
||||
// #define STB_RECT_PACK_IMPLEMENTATION
|
||||
//
|
||||
// in the file that you want to have the implementation.
|
||||
//
|
||||
// Not necessarily the awesomest packing method, but better than
|
||||
// the totally naive one in stb_truetype (which is primarily what
|
||||
// this is meant to replace).
|
||||
//
|
||||
// Has only had a few tests run, may have issues.
|
||||
//
|
||||
// More docs to come.
|
||||
//
|
||||
// No memory allocations; uses qsort() and assert() from stdlib.
|
||||
// Can override those by defining STBRP_SORT and STBRP_ASSERT.
|
||||
//
|
||||
// This library currently uses the Skyline Bottom-Left algorithm.
|
||||
//
|
||||
// Please note: better rectangle packers are welcome! Please
|

// implement them to the same API, but with a different init
