Q: How can I load a different font than the default? (default is an embedded version of ProggyClean.ttf, rendered at size 13)
A: Use the font atlas to load the TTF file you want:
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
Q: How can I load multiple fonts?
A: 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()
// the first loaded font gets used by default
// use ImGui::PushFont()/ImGui::PopFont() to change the font at runtime
// Options
ImFontConfig config;
config.OversampleH = 3;
config.OversampleV = 3;
config.GlyphExtraSpacing.x = 1.0f;
io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, &config);
// Merging input from different fonts into one
ImWchar ranges[] = { 0xf000, 0xf3ff, 0 };
ImFontConfig config;
config.MergeMode = true;
io.Fonts->AddFontDefault();
io.Fonts->LoadFromFileTTF("fontawesome-webfont.ttf", 16.0f, &config, ranges);
io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, NULL, &config, io.Fonts->GetGlyphRangesJapanese());
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()
// the first loaded font gets used by default
// use ImGui::PushFont()/ImGui::PopFont() to change the font at runtime
// Options
ImFontConfig config;
config.OversampleH = 3;
config.OversampleV = 3;
config.GlyphExtraSpacing.x = 1.0f;
io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, &config);
// Combine multiple fonts into one
ImWchar ranges[] = { 0xf000, 0xf3ff, 0 };
ImFontConfig config;
config.MergeMode = true;
io.Fonts->AddFontDefault();
io.Fonts->LoadFromFileTTF("fontawesome-webfont.ttf", 16.0f, &config, ranges);
io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, NULL, &config, io.Fonts->GetGlyphRangesJapanese());
Read extra_fonts/README.txt or ImFontAtlas class for more details.
Q: How can I display and input non-latin characters such as Chinese, Japanese, Korean, Cyrillic?
A: When loading a font, pass custom Unicode ranges to specify the glyphs to load. ImGui will support UTF-8 encoding across the board.
Character input depends on you passing the right character code to io.AddInputCharacter(). The example applications do that.
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, io.Fonts->GetGlyphRangesJapanese()); // Load Japanese characters
io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
io.ImeWindowHandle = MY_HWND; // To input using Microsoft IME, give ImGui the hwnd of your application
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, io.Fonts->GetGlyphRangesJapanese()); // Load Japanese characters
io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
io.ImeWindowHandle = MY_HWND; // To input using Microsoft IME, give ImGui the hwnd of your application
- 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"

ISSUES & TODO-LIST
==================
Issue numbers (#) refer to github issues.
The list below consist mostly of notes of things to do before they are requested/discussed by users (at that point it usually happens on the github)
- misc: merge or clarify ImVec4 vs ImRect?
- 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?)
@ -430,7 +432,8 @@
- slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar).
- slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.
- slider: tint background based on value (e.g. v_min -> v_max, or use 0.0f either side of the sign)
- dragfloat: up/down axis
- slider & drag: int data passing through a float
- drag float: up/down axis
- 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.
@ -454,7 +457,6 @@
- focus: SetKeyboardFocusHere() on with >= 0 offset could be done on same frame (else latch and modulate on beginning of next frame)
- input: rework IO to be able to pass actual events to fix temporal aliasing issues.
- input: support track pad style scrolling & slider edit.
- portability: big-endian test/support (#81)
- memory: add a way to discard allocs of unused/transient windows. with the current architecture new windows (including popup, opened combos, listbox) perform at least 3 allocs.
- 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)
