MISSION STATEMENT
=================
- easy to use to create code-driven and data-driven tools
- easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools
- easy to hack and improve
- minimize screen real-estate usage
- minimize setup and maintenance
- minimize state storage on user side
- portable, minimize dependencies, run on target (consoles, etc.)
- efficient runtime (NB- we do allocate when "growing" content - creating a window / opening a tree node for the first time, etc. - but a typical frame won't allocate anything)
- read about immediate-mode GUI principles @ http://mollyrocket.com/861, http://mollyrocket.com/forums/index.html
Designed for developers and content-creators, not the typical end-user! Some of the weaknesses includes:
- doesn't look fancy, doesn't animate
- limited layout features, intricate layouts are typically crafted in code
- occasionally use statically sized buffers for string manipulations - won't crash, but some long text may be clipped
END-USER GUIDE
==============
- double-click title bar to collapse window
- click upper right corner to close a window, available when 'bool* p_opened' is passed to ImGui::Begin()
- click and drag on lower right corner to resize window
- click and drag on any empty space to move window
- double-click/double-tap on lower right corner grip to auto-fit to content
- TAB/SHIFT+TAB to cycle through keyboard editable fields
- use mouse wheel to scroll
- use CTRL+mouse wheel to zoom window contents (if IO.FontAllowScaling is true)
- CTRL+Click on a slider to input value as text
- text editor:
- Hold SHIFT or use mouse to select text.
- CTRL+Left/Right to word jump
- CTRL+Shift+Left/Right to select words
- CTRL+A our Double-Click to select all
- CTRL+X,CTRL+C,CTRL+V to use OS clipboard
- CTRL+Z,CTRL+Y to undo/redo
- ESCAPE to revert text to its original value
- You can apply arithmetic operators +,*,/ on numerical values. Use +- to subtract (because - would set a negative value!)
PROGRAMMER GUIDE
================
- your code creates the UI, if your code doesn't run the UI is gone! == dynamic UI, no construction step, less data retention on your side, no state duplication, less sync, less errors.
- call and read ImGui::ShowTestWindow() for user-side sample code
- see examples/ folder for standalone sample applications.
- customization: use the style editor or PushStyleColor/PushStyleVar to tweak the look of the interface (e.g. if you want a more compact UI or a different color scheme).
- getting started:
- initialisation: call ImGui::GetIO() and fill the 'Settings' data.
- every frame:
1/ in your mainloop or right after you got your keyboard/mouse info, call ImGui::GetIO() and fill the 'Input' data, then call ImGui::NewFrame().
2/ use any ImGui function you want between NewFrame() and Render()
3/ ImGui::Render() to render all the accumulated command-lists. it will call your RenderDrawListFn handler that you set in the IO structure.
- all rendering information are stored into command-lists until ImGui::Render() is called.
- effectively it means you can create widgets at any time in your code, regardless of "update" vs "render" considerations.
- refer to the examples applications in the examples/ folder for instruction on how to setup your code.
- a typical application skeleton may be:
// Application init
ImGuiIO& io = ImGui::GetIO();
io.DisplaySize.x = 1920.0f;
io.DisplaySize.y = 1280.0f;
io.DeltaTime = 1.0f/60.0f;
io.IniFilename = "imgui.ini";
// TODO: Fill others settings of the io structure
// Load texture
unsigned char* pixels;
int width, height, bytes_per_pixels;
io.Fonts->GetTexDataAsRGBA32(pixels, &width, &height, &bytes_per_pixels);
// TODO: copy texture to graphics memory.
// TODO: store your texture pointer/identifier in 'io.Fonts->TexID'
// Application main loop
while (true)
{
// 1) get low-level input
// e.g. on Win32, GetKeyboardState(), or poll your events, etc.
// 2) TODO: fill all fields of IO structure and call NewFrame
ImGuiIO& io = ImGui::GetIO();
io.MousePos = mouse_pos;
io.MouseDown[0] = mouse_button_0;
io.KeysDown[i] = ...
ImGui::NewFrame();
// 3) most of your application code here - you can use any of ImGui::* functions at any point in the frame
ImGui::Begin("My window");
ImGui::Text("Hello, world.");
ImGui::End();
GameUpdate();
GameRender();
// 4) render & swap video buffers
ImGui::Render();
// swap video buffer, etc.
}
- after calling ImGui::NewFrame() you can read back 'io.WantCaptureMouse' and 'io.WantCaptureKeyboard' to tell if ImGui
wants to use your inputs. if it does you can discard/hide the inputs from the rest of your application.
API BREAKING CHANGES
====================
Occasionally introducing changes that are breaking the API. The breakage are generally minor and easy to fix.
Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
- 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now.
- 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior
- 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing()
- 2015/02/01 (1.31) - removed IO.MemReallocFn (unused)
- 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions.
- 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader.
(1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels.
this sequence:
const void* png_data;
unsigned int png_size;
ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size);
// <Copy to GPU>
became:
unsigned char* pixels;
int width, height;
io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height);
// <Copy to GPU>
io.Fonts->TexID = (your_texture_identifier);
you now have much more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs.
it is now recommended your sample the font texture with bilinear interpolation.
(1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to set io.Fonts->TexID.
(1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix)
(1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets
- 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver)
- 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph)
- 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility
- 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered()
- 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly)
- 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity)
- 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale()
- 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn
- 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically)
- 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite
- 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes
TROUBLESHOOTING & FREQUENTLY ASKED QUESTIONS
============================================
If text or lines are blurry when integrating ImGui in your engine:
- in your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f)
If you are confused about the meaning or use of ID in ImGui:
- many widgets requires state to be carried over multiple frames (most typically ImGui often wants remember what is the "active" widget).
to do so they need an unique ID. unique ID are typically derived from a string label, an indice or a pointer.
when you call Button("OK") the button shows "OK" and also use "OK" as an ID.
- ID are uniquely scoped within Windows so no conflict can happen if you have two buttons called "OK" in two different Windows.
within a same Window, use PushID() / PopID() to easily create scopes and avoid ID conflicts.
so if you have a loop creating "multiple" items, you can use PushID() / PopID() with the index of each item, or their pointer, etc.
some functions like TreeNode() implicitly creates a scope for you by calling PushID()
- when dealing with trees, ID are important because you want to preserve the opened/closed state of tree nodes.
depending on your use cases you may want to use strings, indices or pointers as ID. experiment and see what makes more sense!
e.g. When displaying a single object that may change over time, using a static string as ID will preserve your node open/closed state when the targeted object change
e.g. When displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state per object
- when passing a label you can optionally specify extra unique ID information within the same string using "##". This helps solving the simpler collision cases.
e.g. "Label" display "Label" and uses "Label" as ID
e.g. "Label##Foobar" display "Label" and uses "Label##Foobar" as ID
e.g. "##Foobar" display an empty label and uses "##Foobar" as ID
- read articles about immediate-mode ui principles (see web links) to understand the requirement and use of ID.
If you want to load a different font than the default (ProggyClean.ttf, size 13)
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
If you want to load multiple fonts, use the font atlas to pack them into a single texture!
ImFont* font0 = io.Fonts->AddFontDefault();
ImFont* font1 = io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
ImFont* font2 = io.Fonts->AddFontFromFileTTF("myfontfile2.ttf", size_in_pixels);
io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
If you want to display Chinese, Japanese, Korean characters, pass custom Unicode ranges when loading a font:
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, io.Fonts->GetGlyphRangesJapanese()); // Load Japanese characters
io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
If you want to input Japanese/Chinese/Korean in the text input widget:
- when loading the font, pass a range that contains the characters you need, e.g.: io.Fonts->GetGlyphRangesJapanese()
- to have the Microsoft IME cursor appears at the right location in the screen, setup a handler for the io.ImeSetInputScreenPosFn function:
#include <Windows.h>
#include <Imm.h>
static void ImImpl_ImeSetInputScreenPosFn(int x, int y)
{
// Notify OS Input Method Editor of text input position
HWND hwnd = glfwGetWin32Window(window);
if (HIMC himc = ImmGetContext(hwnd))
{
COMPOSITIONFORM cf;
cf.ptCurrentPos.x = x;
cf.ptCurrentPos.y = y;
cf.dwStyle = CFS_FORCE_POSITION;
ImmSetCompositionWindow(himc, &cf);
}
}
// Set pointer to handler in ImGuiIO structure
io.ImeSetInputScreenPosFn = ImImpl_ImeSetInputScreenPosFn;
- tip: the construct 'IMGUI_ONCE_UPON_A_FRAME { ... }' will run the block of code only once a frame. You can use it to quickly add custom UI in the middle of a deep nested inner loop in your code.
- tip: you can create widgets without a Begin()/End() block, they will go in an implicit window called "Debug"
- tip: you can call Begin() multiple times with the same name during the same frame, it will keep appending to the same window.
- tip: you can call Render() multiple times (e.g for VR renders).
- tip: call and read the ShowTestWindow() code for more example of how to use ImGui!
ISSUES & TODO-LIST
==================
- misc: merge or clarify ImVec4 / ImGuiAabb, they are essentially duplicate containers
- window: add horizontal scroll
- window: fix resize grip rendering scaling along with Rounding style setting
- window: autofit feedback loop when user relies on any dynamic layout (window width multiplier, column). maybe just clearly drop manual autofit?
- window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list.
- window: allow resizing of child windows (possibly given min/max for each axis?)
- window: background options for child windows, border option (disable rounding)
- window: resizing from any sides? + mouse cursor directives for app.
- widgets: clicking on widget b while widget a should activate widget b (doesn't anymore because of hover capture)
- widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc.
- widgets: clip text? hover clipped text shows it in a tooltip or in-place overlay
- main: considering adding EndFrame()/Init(). some constructs are awkward in the implementation because of the lack of them.
- main: IsItemHovered() returns true even if mouse is active on another widget (e.g. dragging outside of sliders). Maybe not a sensible default? Add parameter or alternate function?
- main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes
- main: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode?
- scrollbar: use relative mouse movement when first-clicking inside of scroll grab box.
- scrollbar: make the grab visible and a minimum size for long scroll regions
!- input number: very large int not reliably supported because of int<>float conversions.
- input number: optional range min/max for Input*() functions
- input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled)
- input number: use mouse wheel to step up/down
- input number: non-decimal input.
- layout: horizontal layout helper (github issue #97)
- layout: more generic alignment state (left/right/centered) for single items?
- layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding.
- columns: separator function or parameter that works within the column (currently Separator() bypass all columns)
- columns: declare column set (each column: fixed size, %, fill, distribute default size among fills)
- columns: columns header to act as button (~sort op) and allow resize/reorder
- columns: user specify columns size
- columns: tree node example, removing the last NextColumn() makes a padding difference (it should not)
- combo: turn child handling code into pop up helper
- combo: contents should extends to fit label if combo widget is small
- listbox: multiple selection
- listbox: user may want to initial scroll to focus on the one selected value?
! menubar, menus
- tabs
- gauge: various forms of gauge/loading bars widgets
- color: better color editor.
- plot: make it easier for user to draw extra stuff into the graph (e.g: draw basis, highlight certain points, 2d plots, multiple plots)
- plot: "smooth" automatic scale over time, user give an input 0.0(full user scale) 1.0(full derived from value)
- plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID)
- file selection widget -> build the tool in our codebase to improve model-dialog idioms
- slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
- slider: initial absolute click is imprecise. change to relative movement slider? hide mouse cursor, allow more precise input using less screen-space.
- text edit: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now.
- text edit: centered text for slider as input text so it matches typical positioning.
- text edit: flag to disable live update of the user buffer.
- text edit: field resize behavior - field could stretch when being edited? hover tooltip shows more text?
- text edit: add multi-line text edit
- tree: reformulate OpenNextNode() into SetNextWindowCollapsed() api
- tree: add treenode/treepush int variants? because (void*) cast from int warns on some platforms/settings
- settings: write more decent code to allow saving/loading new fields
- settings: api for per-tool simple persistent data (bool,int,float) in .ini file
! style: store rounded corners in texture to use 1 quad per corner (filled and wireframe). so rounding have minor cost.
- style: checkbox: padding for "active" color should be a multiplier of the
- style: colorbox not always square?
- text: simple markup language for color change?
- log: LogButtons() options for specifying depth and/or hiding depth slider
- log: have more control over the log scope (e.g. stop logging when leaving current tree node scope)
- log: be able to right-click and log a window or tree-node into tty/file/clipboard / generalized context menu?
- filters: set a current filter that tree node can automatically query to hide themselves
- filters: handle wildcards (with implicit leading/trailing *), regexps
- shortcuts: add a shortcut api, e.g. parse "&Save" and/or "Save (CTRL+S)", pass in to widgets or provide simple ways to use (button=activate, input=focus)
! keyboard: tooltip & combo boxes are messing up / not honoring keyboard tabbing
- keyboard: full keyboard navigation and focus.
- input: rework IO to be able to pass actual events to fix temporal aliasing issues.
- input: support track pad style scrolling & slider edit.
- tooltip: move to fit within screen (e.g. when mouse cursor is right of the screen).
- portability: big-endian test/support (github issue #81)
- misc: mark printf compiler attributes on relevant functions
- misc: provide a way to compile out the entire implementation while providing a dummy API (e.g. #define IMGUI_DUMMY_IMPL)
- misc: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon?
- style editor: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space?
- style editor: color child window height expressed in multiple of line height.
- optimization/render: use indexed rendering to reduce vertex data cost (for remote/networked imgui)
- optimization/render: merge command-lists with same clip-rect into one even if they aren't sequential? (as long as in-between clip rectangle don't overlap)?
- optimization: turn some the various stack vectors into statically-sized arrays
- optimization: better clipping for multi-component widgets
- optimization: specialize for height based clipping first (assume widgets never go up + height tests before width tests?)
