IM_VEC4_CLASS_EXTRA// Define additional constructors and implicit cast operators in imconfig.h to convert back and forth between your math types and ImVec4.
// Each context create its own ImFontAtlas by default. You may instance one yourself and pass it to CreateContext() to share a font atlas between imgui contexts.
IMGUI_APIvoidNewFrame();// start a new Dear ImGui frame, you can submit any command from this point until Render()/EndFrame().
IMGUI_APIvoidEndFrame();// ends the Dear ImGui frame. automatically called by Render(), you likely don't need to call that yourself directly. If you don't need to render data (skipping rendering) you may call EndFrame() but you'll have wasted CPU already! If you don't need to render, better to not create any imgui windows and not call NewFrame() at all!
IMGUI_APIvoidRender();// ends the Dear ImGui frame, finalize the draw data. You can get call GetDrawData() to obtain it and run your rendering function. (Obsolete: this used to call io.RenderDrawListsFn(). Nowadays, we allow and prefer calling your render function yourself.)
IMGUI_APIImDrawData*GetDrawData();// valid after Render() and until the next call to NewFrame(). this is what you have to render.
IMGUI_APIvoidShowDemoWindow(bool*p_open=NULL);// create demo/test window (previously called ShowTestWindow). demonstrate most ImGui features. call this to learn about the library! try to make it always available in your application!

// - Use child windows to begin into a self-contained independent scrolling/clipping regions within a host window. Child windows can embed their own child.
// - For each independent axis of 'size': ==0.0f: use remaining host window size / >0.0f: fixed size / <0.0f: use remaining window size minus abs(size) / Each axis can use a different mode, e.g. ImVec2(0,400).
// - BeginChild() returns false to indicate the window is collapsed or fully clipped, so you may early out and omit submitting anything to the window.
// Always call a matching EndChild() for each BeginChild() call, regardless of its return value [this is due to legacy reason and is inconsistent with most other functions such as BeginMenu/EndMenu, BeginPopup/EndPopup, etc. where the EndXXX call should only be called if the corresponding BeginXXX function returned true.]
IMGUI_APIboolIsWindowFocused(ImGuiFocusedFlagsflags=0);// is current window focused? or its root/child, depending on flags. see flags for options.
IMGUI_APIboolIsWindowHovered(ImGuiHoveredFlagsflags=0);// is current window hovered (and typically: not blocked by a popup/modal)? see flags for options. NB: If you are trying to check whether your mouse should be dispatched to imgui or to your app, you should use the 'io.WantCaptureMouse' boolean for that! Please read the FAQ!
IMGUI_APIvoidSetNextWindowPos(constImVec2&pos,ImGuiCondcond=0,constImVec2&pivot=ImVec2(0,0));// set next window position. call before Begin(). use pivot=(0.5f,0.5f) to center on given point, etc.

IMGUI_APIvoidSetScrollHereY(floatcenter_y_ratio=0.5f);// adjust scrolling amount to make current cursor position visible. center_y_ratio=0.0: top, 0.5: center, 1.0: bottom. When using to make a "default/current item" visible, consider using SetItemDefaultFocus() instead.
IMGUI_APIvoidSetScrollFromPosY(floatlocal_y,floatcenter_y_ratio=0.5f);// adjust scrolling amount to make given position visible. Generally GetCursorStartPos() + offset to compute a valid position.
IMGUI_APIconstImVec4&GetStyleColorVec4(ImGuiColidx);// retrieve style color as stored in ImGuiStyle structure. use to feed back into PushStyleColor(), otherwise use GetColorU32() to get style color with style alpha baked in.
IMGUI_APIvoidPushItemWidth(floatitem_width);// set width of items for common large "item+label" widgets. >0.0f: width in pixels, <0.0f align xx pixels to the right of window (so -1.0f always align width to the right side). 0.0f = default to ~2/3 of windows width,

IMGUI_APIvoidPushAllowKeyboardFocus(boolallow_keyboard_focus);// allow focusing using TAB/Shift-TAB, enabled by default but you can disable it for certain widgets
IMGUI_APIvoidPushButtonRepeat(boolrepeat);// in 'repeat' mode, Button*() functions return repeated true in a typematic manner (using io.KeyRepeatDelay/io.KeyRepeatRate setting). Note that you can call IsItemActive() after any Button() to tell if the button is held in the current frame.
IMGUI_APIvoidSameLine(floatoffset_from_start_x=0.0f,floatspacing=-1.0f);// call between widgets or groups to layout them horizontally. X position given in window coordinates.
IMGUI_APIvoidNewLine();// undo a SameLine() or force a new line when in an horizontal-layout context.
IMGUI_APIvoidSpacing();// add vertical spacing.
IMGUI_APIvoidDummy(constImVec2&size);// add a dummy item of given size. unlike InvisibleButton(), Dummy() won't take the mouse click or be navigable into.
IMGUI_APIvoidBeginGroup();// lock horizontal starting position

IMGUI_APIvoidTextUnformatted(constchar*text,constchar*text_end=NULL);// raw text without formatting. Roughly equivalent to Text("%s", text) but: A) doesn't require null terminated string if 'text_end' is specified, B) it's faster, no memory copy is done, no buffer size limits, recommended for long chunks of text.
IMGUI_APIvoidText(constchar*fmt,...)IM_FMTARGS(1);// simple formatted text
IMGUI_APIvoidTextWrapped(constchar*fmt,...)IM_FMTARGS(1);// shortcut for PushTextWrapPos(0.0f); Text(fmt, ...); PopTextWrapPos();. Note that this won't work on an auto-resizing window if there's no other widgets to extend the window width, yoy may need to set a size using SetNextWindowSize().

// - For all the Float2/Float3/Float4/Int2/Int3/Int4 versions of every functions, note that a 'float v[X]' function argument is the same as 'float* v', the array syntax is just a way to document the number of elements that are expected to be accessible. You can pass address of your first element out of a contiguous set, e.g. &myvector.x
// - Adjust format string to decorate the value with a prefix, a suffix, or adapt the editing and display precision e.g. "%.3f" -> 1.234; "%5.2f secs" -> 01.23 secs; "Biscuit: %.0f" -> Biscuit: 1; etc.

IMGUI_APIvoidSetNextTreeNodeOpen(boolis_open,ImGuiCondcond=0);// set next TreeNode/CollapsingHeader open state.
IMGUI_APIboolCollapsingHeader(constchar*label,ImGuiTreeNodeFlagsflags=0);// if returning 'true' the header is open. doesn't indent nor push on ID stack. user doesn't have to call TreePop().
IMGUI_APIboolCollapsingHeader(constchar*label,bool*p_open,ImGuiTreeNodeFlagsflags=0);// when 'p_open' isn't NULL, display an additional small close button on upper right of the header
IMGUI_APIboolSelectable(constchar*label,boolselected=false,ImGuiSelectableFlagsflags=0,constImVec2&size=ImVec2(0,0));// "bool selected" carry the selection state (read-only). Selectable() is clicked is returns true so you can modify your selection state. size.x==0.0: use remaining width, size.x>0.0: specify width. size.y==0.0: use label height, size.y>0.0: specify height

IMGUI_APIvoidSetTooltip(constchar*fmt,...)IM_FMTARGS(1);// set a text-only tooltip, typically use with ImGui::IsItemHovered(). override any previous call to SetTooltip().
IMGUI_APIvoidOpenPopup(constchar*str_id);// call to mark popup as open (don't call every frame!). popups are closed when user click outside, or if CloseCurrentPopup() is called within a BeginPopup()/EndPopup() block. By default, Selectable()/MenuItem() are calling CloseCurrentPopup(). Popup identifiers are relative to the current ID-stack (so OpenPopup and BeginPopup needs to be at the same level).
IMGUI_APIboolBeginPopup(constchar*str_id,ImGuiWindowFlagsflags=0);// return true if the popup is open, and you can start outputting to it. only call EndPopup() if BeginPopup() returns true!

IMGUI_APIboolIsItemDeactivatedAfterEdit();// was the last item just made inactive and made a value change when it was active? (e.g. Slider/Drag moved). Useful for Undo/Redo patterns with widgets that requires continuous editing. Note that you may get false positives (some widgets such as Combo()/ListBox()/Selectable() will return true even when clicking an already selected item).

IMGUI_APIboolIsKeyPressed(intuser_key_index,boolrepeat=true);// was key pressed (went from !Down to Down). if repeat=true, uses io.KeyRepeatDelay / KeyRepeatRate
IMGUI_APIboolIsKeyReleased(intuser_key_index);// was key released (went from Down to !Down)..
IMGUI_APIintGetKeyPressedAmount(intkey_index,floatrepeat_delay,floatrate);// uses provided repeat rate/delay. return a count, most often 0 or 1 but might be >1 if RepeatRate is small enough that DeltaTime > RepeatRate

IMGUI_APIvoidCaptureKeyboardFromApp(boolwant_capture_keyboard_value=true);// attention: misleading name! manually override io.WantCaptureKeyboard flag next frame (said flag is entirely left for your application to handle). e.g. force capture keyboard when your widget is being hovered. This is equivalent to setting "io.WantCaptureKeyboard = want_capture_keyboard_value"; after the next NewFrame() call.
IMGUI_APIvoidCaptureMouseFromApp(boolwant_capture_mouse_value=true);// attention: misleading name! manually override io.WantCaptureMouse flag next frame (said flag is entirely left for your application to handle).

ImGuiInputTextFlags_NoUndoRedo=1<<16,// Disable undo/redo. Note that input text owns the text data while active, if you want to provide your own undo/redo stack you need e.g. to call ClearActiveID().
ImGuiInputTextFlags_CallbackResize=1<<18,// Callback on buffer capacity changes request (beyond 'buf_size' parameter value), allowing the string to grow. Notify when the string wants to be resized (for string types which hold a cache of their Size). You will be provided a new BufSize in the callback and NEED to honor it. (see misc/cpp/imgui_stdlib.h for an example of using this)
ImGuiTreeNodeFlags_NoAutoOpenOnLog=1<<4,// Don't automatically and temporarily open node when Logging is active (by default logging will automatically open tree nodes)

ImGuiComboFlags_PopupAlignLeft=1<<0,// Align the popup toward the left by default
ImGuiComboFlags_HeightSmall=1<<1,// Max ~4 items visible. Tip: If you want your combo popup to be a specific size you can use SetNextWindowSizeConstraints() prior to calling BeginCombo()

//ImGuiHoveredFlags_AllowWhenBlockedByModal = 1 << 4, // Return true even if a modal popup window is normally blocking access to this item/window. FIXME-TODO: Unavailable yet.
ImGuiHoveredFlags_AllowWhenBlockedByActiveItem=1<<5,// Return true even if an active item is blocking access to this item/window. Useful for Drag and Drop patterns.
ImGuiHoveredFlags_AllowWhenOverlapped=1<<6,// Return true even if the position is overlapped by another window
ImGuiDragDropFlags_SourceNoPreviewTooltip=1<<0,// By default, a successful call to BeginDragDropSource opens a tooltip so you can display a preview or description of the source contents. This flag disable this behavior.
ImGuiDragDropFlags_SourceNoDisableHover=1<<1,// By default, when dragging we clear data so that IsItemHovered() will return false, to avoid subsequent user code submitting tooltips. This flag disable this behavior so you can still call IsItemHovered() on the source item.
ImGuiDragDropFlags_SourceNoHoldToOpenOthers=1<<2,// Disable the behavior that allows to open tree nodes and collapsing header by holding over them while dragging a source item.
ImGuiDragDropFlags_SourceAllowNullID=1<<3,// Allow items such as Text(), Image() that have no unique identifier to be used as drag source, by manufacturing a temporary identifier based on their window-relative position. This is extremely unusual within the dear imgui ecosystem and so we made it explicit.
ImGuiDragDropFlags_SourceExtern=1<<4,// External source (from outside of imgui), won't attempt to read current item/window info. Will always return true. Only one Extern source can be active simultaneously.
ImGuiDragDropFlags_SourceAutoExpirePayload=1<<5,// Automatically expire the payload if the source cease to be submitted (otherwise payloads are persisting while being dragged)

// [Internal] Don't use directly! This is used internally to differentiate keyboard from gamepad inputs for behaviors that require to differentiate them.
ImGuiConfigFlags_NavEnableKeyboard=1<<0,// Master keyboard navigation enable flag. NewFrame() will automatically fill io.NavInputs[] based on io.KeysDown[].
ImGuiConfigFlags_NavEnableGamepad=1<<1,// Master gamepad navigation enable flag. This is mostly to instruct your imgui back-end to fill io.NavInputs[]. Back-end also needs to set ImGuiBackendFlags_HasGamepad.
ImGuiConfigFlags_NavEnableSetMousePos=1<<2,// Instruct navigation to move the mouse cursor. May be useful on TV/console systems where moving a virtual mouse is awkward. Will update io.MousePos and set io.WantSetMousePos=true. If enabled you MUST honor io.WantSetMousePos requests in your binding, otherwise ImGui will react as if the mouse is jumping around back and forth.
ImGuiConfigFlags_NavNoCaptureKeyboard=1<<3,// Instruct navigation to not set the io.WantCaptureKeyboard flag when io.NavActive is set.
ImGuiConfigFlags_NoMouse=1<<4,// Instruct imgui to clear mouse position/buttons in NewFrame(). This allows ignoring the mouse information set by the back-end.
ImGuiConfigFlags_NoMouseCursorChange=1<<5,// Instruct back-end to not alter mouse cursor shape and visibility. Use if the back-end cursor changes are interfering with yours and you don't want to use SetMouseCursor() to change mouse cursor. You may want to honor requests from imgui by reading GetMouseCursor() yourself instead.
// User storage (to allow your back-end/engine to communicate to code that may be shared between multiple projects. Those flags are not used by core ImGui)

// Important: Treat as a regular enum! Do NOT combine multiple values using binary operators! All the functions above treat 0 as a shortcut to ImGuiCond_Always.
// We call C++ constructor on own allocated memory via the placement "new(ptr) Type()" syntax.
// Defining a custom placement new() with a dummy parameter allows us to bypass including <new> which on some platforms complains when user has disabled exceptions.
// Lightweight std::vector<>-like class to avoid dragging dependencies (also, some implementations of STL with debug enabled are absurdly slow, we bypass it so our code runs fast in debug).
// You generally do NOT need to care or use this ever. But we need to make it available in imgui.h because some of our data structures are relying on it.
// Important: clear() frees memory, resize(0) keep the allocated buffer. We use resize(0) a lot to intentionally recycle allocated buffers across frames and amortize our costs.
// Important: our implementation does NOT call C++ constructors/destructors, we treat everything as raw data! This is intentional but be extra mindful of that,
// do NOT use this class as a std::vector replacement in your own code! Many of the structures used by dear imgui can be safely initialized by a zero-memset.
// NB: It is illegal to call push_back/push_front/insert with a reference pointing inside the ImVector data itself! e.g. v.push_back(v[10]) is forbidden.

ImVec2DisplayWindowPadding;// Window position are clamped to be visible within the display area by at least this amount. Only applies to regular windows.
ImVec2DisplaySafeAreaPadding;// If you cannot see the edges of your screen (e.g. on a TV) increase the safe area padding. Apply to popups/tooltips as well regular windows. NB: Prefer configuring your TV sets correctly!

ImGuiInputTextFlagsFlags;// What user passed to InputText() // Read-only
void*UserData;// What user passed to InputText() // Read-only
// Arguments for the different callback events
// - To modify the text buffer in a callback, prefer using the InsertChars() / DeleteChars() function. InsertChars() will take care of calling the resize callback if necessary.
// - If you know your edits are not going to resize the underlying buffer allocation, you may modify the contents of 'Buf[]' directly. You need to update 'BufTextLen' accordingly (0 <= BufTextLen < BufSize) and set 'BufDirty'' to true so InputText can update its internal state.

// Helper: Execute a block of code at maximum once a frame. Convenient if you want to quickly create an UI within deep-nested code that runs multiple times every frame.
// Helper: Macro for ImGuiOnceUponAFrame. Attention: The macro expands into 2 statement so make sure you don't use it within e.g. an if() statement without curly braces.
// We use it to e.g. store collapse state for a tree (Int 0/1)
// This is optimized for efficient lookup (dichotomy into a contiguous buffer) and rare insertion (typically tied to user interactions aka max once a frame)
// - References are only valid until a new value is added to the storage. Calling a Set***() function or a Get***Ref() function invalidates the pointer.
// - A typical use case where this is convenient for quick hacking (e.g. add storage during a live Edit&Continue session if you can't modify existing struct)
// If you are submitting lots of evenly spaced items and you have a random access to the list, you can perform coarse clipping based on visibility to save yourself from processing those items at all.
// The clipper calculates the range of visible items and advance the cursor to compensate for the non-visible items we have skipped.
// ImGui already clip items based on their bounds but it needs to measure text size to do so. Coarse clipping before submission makes this cost and your own data fetching/submission cost null.
// Usage:
// ImGuiListClipper clipper(1000); // we have 1000 elements, evenly spaced.
// while (clipper.Step())
// for (int i = clipper.DisplayStart; i < clipper.DisplayEnd; i++)
// ImGui::Text("line number %d", i);
// - Step 0: the clipper let you process the first element, regardless of it being visible or not, so we can measure the element height (step skipped if we passed a known height as second arg to constructor).
// - Step 1: the clipper infer height from first element, calculate the actual range of elements to display, and position the cursor before the first element.
// - (Step 2: dummy step only required if an explicit items_height was passed to constructor or Begin() and user call Step(). Does nothing and switch to Step 3.)
// - Step 3: the clipper validate that we have reached the expected Y position (corresponding to element DisplayEnd), advance the cursor to the end of the list and then returns 'false' to end the loop.

IMGUI_APIvoidDeIndexAllBuffers();// Helper to convert all buffers from indexed to non-indexed, in case you cannot render indexed. Note: this is slow and most likely a waste of resources. Always prefer indexed rendering!
IMGUI_APIvoidScaleClipRects(constImVec2&fb_scale);// Helper to scale the ClipRect field of each ImDrawCmd. Use if your final output buffer is at a different scale than ImGui expects, or if there is a difference between your window resolution and framebuffer resolution.
intOversampleH;// 3 // Rasterize at higher quality for sub-pixel positioning. Read https://github.com/nothings/stb/blob/master/tests/oversample/README.md for details.
boolPixelSnapH;// false // Align every glyph to pixel boundary. Useful e.g. if you are merging a non-pixel aligned font with the default font. If enabled, you can set OversampleH/V to 1.
ImVec2GlyphExtraSpacing;// 0, 0 // Extra spacing (in pixels) between glyphs. Only X axis is supported for now.
ImVec2GlyphOffset;// 0, 0 // Offset all glyphs from this font input.
constImWchar*GlyphRanges;// NULL // Pointer to a user-provided list of Unicode range (2 value per range, values are inclusive, zero-terminated list). THE ARRAY DATA NEEDS TO PERSIST AS LONG AS THE FONT IS ALIVE.
boolMergeMode;// false // Merge into previous ImFont, so you can combine multiple inputs font into one ImFont (e.g. ASCII font + icons + Japanese glyphs). You may want to use GlyphOffset.y when merge font of different heights.
unsignedintRasterizerFlags;// 0x00 // Settings for custom font rasterizer (e.g. ImGuiFreeType). Leave as zero if you aren't using one.
floatRasterizerMultiply;// 1.0f // Brighten (>1.0f) or darken (<1.0f) font output. Brightening small fonts may be a good workaround to make them more readable.
boolGetBit(intn)const{intoff=(n>>5);intmask=1<<(n&31);return(UsedChars[off]&mask)!=0;}// Get bit n in the array
voidSetBit(intn){intoff=(n>>5);intmask=1<<(n&31);UsedChars[off]|=mask;}// Set bit n in the array

Will be deleted after destruction of the atlas. Set font_cfg->FontDataOwnedByAtlas=false to keep ownership of your data and it won't be freed.
IMGUI_APIImFont*AddFontFromMemoryCompressedTTF(constvoid*compressed_font_data,intcompressed_font_size,floatsize_pixels,constImFontConfig*font_cfg=NULL,constImWchar*glyph_ranges=NULL);// 'compressed_font_data' still owned by caller. Compress with binary_to_compressed_c.cpp.
IMGUI_APIImFont*AddFontFromMemoryCompressedBase85TTF(constchar*compressed_font_data_base85,floatsize_pixels,constImFontConfig*font_cfg=NULL,constImWchar*glyph_ranges=NULL);// 'compressed_font_data_base85' still owned by caller. Compress with binary_to_compressed_c.cpp with -base85 parameter.
IMGUI_APIvoidClearInputData();// Clear input data (all ImFontConfig structures including sizes, TTF data, glyph ranges, etc.) = all the data used to build the texture and fonts.
IMGUI_APIvoidClearTexData();// Clear output texture data (CPU side). Saves RAM once the texture has been copied to graphics memory.
IMGUI_APIvoidClearFonts();// Clear output font data (glyphs storage, UV coordinates).
IMGUI_APIvoidClear();// Clear all input and output.
// User is in charge of copying the pixels into graphics memory (e.g. create a texture with your engine). Then store your texture handle with SetTexID().
// NB: Make sure that your string are UTF-8 and NOT in your local code page. In C++11, you can create UTF-8 string literal using the u8"Hello world" syntax. See FAQ for details.
IMGUI_APIconstImWchar*GetGlyphRangesDefault();// Basic Latin, Extended Latin
IMGUI_APIconstImWchar*GetGlyphRangesKorean();// Default + Korean characters
IMGUI_APIconstImWchar*GetGlyphRangesJapanese();// Default + Hiragana, Katakana, Half-Width, Selection of 1946 Ideographs
IMGUI_APIconstImWchar*GetGlyphRangesChineseFull();// Default + Half-Width + Japanese Hiragana/Katakana + full set of about 21000 CJK Unified Ideographs

IMGUI_APIconstImWchar*GetGlyphRangesCyrillic();// Default + about 400 Cyrillic characters
// You can request arbitrary rectangles to be packed into the atlas, for your own purposes. After calling Build(), you can query the rectangle position and render your pixels.
// You can also request your rectangles to be mapped as font glyph (given a font + Unicode point), so you can render e.g. custom colorful icons and use them as regular glyphs.

ImTextureIDTexID;// User data to refer to the texture once it has been uploaded to user's graphic systems. It is passed back to you during rendering via the ImDrawCmd structure.
intTexDesiredWidth;// Texture width desired by user before Build(). Must be a power-of-two. If have many glyphs your graphics API have texture size restrictions you may want to increase texture width to decrease height.
intTexGlyphPadding;// Padding between glyphs within texture in pixels. Defaults to 1. If your rendering method doesn't rely on bilinear filtering you may set this to 0.
ImVec2TexUvWhitePixel;// Texture coordinates to a white pixel
ImVector<ImFont*>Fonts;// Hold all the fonts returned by AddFont*. Fonts[0] is the default font upon calling ImGui::NewFrame(), use ImGui::PushFont()/PopFont() to change the current font.
ImVector<float>IndexAdvanceX;// 12-16 // out // // Sparse. Glyphs->AdvanceX in a directly indexable way (cache-friendly for CalcTextSize functions which only this this info, and are often bottleneck in large UI).
shortConfigDataCount;// 2 // in // ~ 1 // Number of ImFontConfig involved in creating this font. Bigger than 1 when merging multiple font sources into one ImFont.
intMetricsTotalSurface;// 4 // out // // Total surface in pixels to get an idea of the font rasterization/texture cost (not exact, we approximate the cost of padding between glyphs)
IMGUI_APIvoidAddRemapChar(ImWchardst,ImWcharsrc,booloverwrite_dst=true);// Makes 'dst' character/glyph points to 'src' character/glyph. Currently needs to be called AFTER fonts have been built.
