VERSION 1.92.0 WIP (In Progress)
-----------------------------------------------------------------------
THIS VERSION CONTAINS THE LARGEST AMOUNT OF BREAKING CHANGES SINCE 2015!
I TRIED REALLY HARD TO KEEP THEM TO A MINIMUM, REDUCE THE AMOUNT OF INTERFERENCES,
BUT INEVITABLY SOME USERS WILL BE AFFECTED.
IN ORDER TO HELP US IMPROVE THE TRANSITION PROCESS, INCL. DOCUMENTATION AND COMMENTS,
PLEASE REPORT **ANY** DOUBT, CONFUSION, QUESTIONS, FEEDBACK TO:
https://github.com/ocornut/imgui/issues/
As part of the plan to reduce impact of API breaking changes, several unfinished
changes/features/refactors related to font and text systems and scaling will be
part of subsequent releases (1.92.1+).
If you are updating from an old version, and expecting a massive or difficult update,
consider first updating to 1.91.9 to reduce the amount of changes.
Breaking changes:
- Fonts: **IMPORTANT**: if your app was solving the OSX/iOS Retina screen specific
logical vs display scale problem by setting io.DisplayFramebufferScale (e.g. to 2.0f)
+ setting io.FontGlobalScale (e.g. to 1.0f/2.0f) + loading fonts at scaled sizes (e.g. size X * 2.0f):
This WILL NOT map correctly to the new system! Because font will rasterize as requested size.
- With a legacy backend (< 1.92):
- Instead of setting io.FontGlobalScale = 1.0f/N -> set ImFontCfg::RasterizerDensity = N.
- This already worked before, but is now pretty much required.
- With a new backend (1.92+)
- FramebufferScale is automatically used to set current font RasterizerDensity.
- FramebufferScale is a per-viewport property provided by backend through the
Platform_GetWindowFramebufferScale() handler in 'docking' branch.
- So this should be all automatic.
- Fonts: **IMPORTANT** on Font Sizing:
- Before 1.92, fonts were of a single size. They can now be dynamically sized.
- PushFont() API now has an optional size parameter. PushFontSize() was also added.
void PushFont(ImFont* font) --> void PushFont(ImFont* font, float size = 0.0f);
- Before 1.92: ImGui::PushFont() always used font "default" size specified in AddFont() call.
- Since 1.92: ImGui::PushFont() preserve the current font size which is a shared value.
- To use old behavior:
- use 'ImGui::PushFont(font, font->LegacySize)' at call site.
- or set 'ImFontConfig::Flags |= ImFontFlags_DefaultToLegacySize' in AddFont() call
(not desirable as it requires e.g. third-party code to be aware of it).
- ImFont::FontSize was removed and does not make sense anymore.
ImFont::LegacySize is the size passed to AddFont().
- Renamed/moved 'io.FontGlobalScale' to 'style.FontScaleMain'.
- Textures:
- All API functions taking a 'ImTextureID' parameter are now taking a 'ImTextureRef':
- ImTextureRef a small composite structure which may be constructed from a ImTextureID.
(or constructed from a ImTextureData* which represent a texture which will generally
be ready by the time of rendering).
- Affected functions are:
- ImGui::Image(), ImGui::ImageWithBg(), ImGui::ImageButton(),
- ImDrawList::AddImage(), ImDrawList::AddImageQuad(), ImDrawList::AddImageRounded().
- We suggest that C users and any higher-level language bindings generators may
facilitate converting this in some way, aka emulating the trivial C++ constructor.
- Fonts: obsoleted ImFontAtlas::GetTexDataAsRGBA32(), GetTexDataAsAlpha8(), Build(), SetTexID()
and IsBuilt() functions. The new protocol for backends to handle textures doesn't need them.
Kept redirection functions (will obsolete).
- A majority of old backends should still work with new code (behaving like they did before).
- Calling ImFontAtlas::Build() before initializing new backends will erroneously trigger
preloading all glyphs. Will be detected with an assertion after the backend is initialized.
- Fonts: ImFontConfig::OversampleH/OversampleV default to automatic (== 0)
since v1.91.8. It is quite important you keep it automatic until we decide if we want
to provide a way to express finer policy, otherwise you will likely waste texture space
when using large glyphs. Note that the imgui_freetype backend doesn't use and does not
need oversampling.
- Fonts: specifying glyph ranges is now unnecessary.
- The value of ImFontConfig::GlyphRanges[] is only useful for legacy backends.
- All GetGlyphRangesXXXX() functions are now marked obsolete:
- GetGlyphRangesDefault(), GetGlyphRangesGreek(), GetGlyphRangesKorean(),
GetGlyphRangesJapanese(), GetGlyphRangesChineseSimplifiedCommon(),
GetGlyphRangesChineseFull(), GetGlyphRangesCyrillic(),
GetGlyphRangesThai(), GetGlyphRangesVietnamese().
- Fonts: removed ImFontAtlas::TexDesiredWidth to enforce a texture width. (#327)
(it vaguely made sense with the old system as if unspecified textures width maxed up
to 4096 but that limit isn't necessary anymore, and Renderer_TextureMaxWidth covers this)
However you may set TexMinWidth = TexMaxWidth for the same effect.
- Fonts: if you create and manage ImFontAtlas instances yourself (instead of relying on
ImGuiContext to create one, you'll need to set the atlas->RendererHasTextures field
and call ImFontAtlasUpdateNewFrame() yourself. An assert will trigger if you don't.
- Fonts: obsolete ImGui::SetWindowFontScale() which is not useful anymore. Prefer using
PushFontSize(style.FontSizeBase * factor) or to manipulate other scaling factors.
- Fonts: obsoleted ImFont::Scale which is not useful anymore.
- Fonts: changed ImFont::CalcWordWrapPositionA() to ImFont::CalcWordWrapPosition():
- old: const char* CalcWordWrapPositionA(float scale, const char* text, ....);
- new: const char* CalcWordWrapPosition (float size, const char* text, ....);
The leading 'float scale' parameters was changed to 'float size'.
This was necessary as 'scale' is assuming a unique font size.
Kept inline redirection function assuming using font->LegacySize.
- Fonts: generally reworked Internals of ImFontAtlas and ImFont.
While in theory a vast majority of users shouldn't be affected, some use cases or
extensions might be. Among other things:
- ImDrawCmd::TextureId has been changed to ImDrawCmd::TexRef.
- ImFontAtlas::ConfigData[] has been renamed to ImFontAtlas::Sources[]
- ImFont::ConfigData[], ConfigDataCount has been renamed to Sources[], SourceCount.
- Each ImFont has a number of ImFontBaked instances corresponding to actively used
sizes. ImFont::GetFontBaked(size) retrieves the one for a given size.
- Things moved from ImFont to ImFontBaked:
- ImFont::IndexAdvanceX[] -> ImFontBaked::IndexAdvanceX[]
- ImFont::Glyphs[] -> ImFontBaked::Glyphs[]
- ImFont::Ascent, Descent -> ImFontBaked::Ascent, Descent
- ImFont::FindGlyph() -> ImFontBaked::FindGlyph()
- ImFont::FindGlyphNoFallback() -> ImFontBaked::FindGlyphNoFallback()
- ImFont::GetCharAdvance() -> ImFontBaked::GetCharAdvance()
- Widget code may use ImGui::GetFontBaked() instead of ImGui::GetFont() to
access font data for current font at current font size.
(and you may use font->GetFontBaked(size) to access it for any other size.)
g.Font == ImGui::GetFont()
g.FontSize == ImGui::GetFontSize()
g.FontBaked == ImGui::GetFontBaked() == ImGui::GetFont()->GetFontBaked(ImGui::GetFontSize())
Please report if you are affected!
- Fonts: (users of imgui_freetype)
- renamed ImFontAtlas::FontBuilderFlags to ImFontAtlas::FontLoaderFlags.
- renamed ImFontConfig::FontBuilderFlags to ImFontConfig::FontLoaderFlags.
- renamed ImGuiFreeTypeBuilderFlags to ImGuiFreeTypeLoaderFlags.
- if you used runtime imgui_freetype selection rather than the default compile-time
option provided by IMGUI_ENABLE_FREETYPE:
- renamed/reworked ImFontBuilderIO into ImFontLoader,
- renamed ImGuiFreeType::GetBuilderForFreeType() to ImGuiFreeType::GetFontLoader().
- old: io.Fonts->FontBuilderIO = ImGuiFreeType::GetBuilderForFreeType()
- new: io.Fonts.FontLoader = ImGuiFreeType::GetFontLoader()
- DrawList: Renamed ImDrawList::PushTextureID()/PopTextureID() to PushTexture()/PopTexture().
- Fonts: (users of custom rectangles)
- Renamed AddCustomRectRegular() to AddCustomRect(). (#8466)
- Added GetCustomRect() as a replacement for GetCustomRectByIndex() + CalcCustomRectUV(). (#8466)
- The output type of GetCustomRect() is now ImFontAtlasRect, which include UV coordinates.
- ImFontAtlasCustomRect::X --> ImFontAtlasRect::x
- ImFontAtlasCustomRect::Y --> ImFontAtlasRect::y
- ImFontAtlasCustomRect::Width --> ImFontAtlasRect::w
- ImFontAtlasCustomRect::Height --> ImFontAtlasRect::h
Before:
const ImFontAtlasCustomRect* r = atlas->GetCustomRectByIndex(custom_rect_id);
ImVec2 uv0, uv1;
atlas->GetCustomRectUV(r, &uv0, &uv1);
ImGui::Image(atlas->TexRef, ImVec2(r->w, r->h), uv0, uv1);
After:
ImFontAtlasRect r;
atlas->GetCustomRect(custom_rect_id, &r);
ImGui::Image(atlas->TexRef, ImVec2(r.w, r.h), r.uv0, r.uv1);
We added a redirecting typedef but haven't attempted to magically redirect
the field names, as this API is rarely used and the fix is simple.
- Obsoleted AddCustomRectFontGlyph() as the API does not make sense for scalable fonts:
- Kept existing function which uses the font "default size" (Sources[0]->LegacySize).
- Added a helper AddCustomRectFontGlyphForSize() which is immediately marked obsolete,
but can facilitate transitioning old code.
- Prefer adding a font source (ImFontConfig) using a custom/procedural loader.
- Backends: removed ImGui_ImplXXXX_CreateFontsTexture()/ImGui_ImplXXXX_DestroyFontsTexture()
for all backends that had them. They should not be necessary any more.
- removed ImGui_ImplMetal_CreateFontsTexture(), ImGui_ImplMetal_DestroyFontsTexture().
- removed ImGui_ImplOpenGL2_CreateFontsTexture(), ImGui_ImplOpenGL2_DestroyFontsTexture().
- removed ImGui_ImplOpenGL3_CreateFontsTexture(), ImGui_ImplOpenGL3_DestroyFontsTexture().
- removed ImGui_ImplSDLGPU3_CreateFontsTexture(), ImGui_ImplSDLGPU3_DestroyFontsTexture().
- removed ImGui_ImplSDLRenderer2_CreateFontsTexture(), ImGui_ImplSDLRenderer2_DestroyFontsTexture().
- removed ImGui_ImplSDLRenderer3_CreateFontsTexture(), ImGui_ImplSDLRenderer3_DestroyFontsTexture().
- removed ImGui_ImplVulkan_CreateFontsTexture(), ImGui_ImplVulkan_DestroyFontsTexture().
- TreeNode: renamed ImGuiTreeNodeFlags_NavLeftJumpsBackHere to ImGuiTreeNodeFlags_NavLeftJumpsToParent
for clarity. Kept inline redirection enum (will obsolete). (#1079, #8639)
- Fonts: changed ImFont::CalcWordWrapPositionA() to ImFont::CalcWordWrapPosition():
- old: const char* CalcWordWrapPositionA(float scale, const char* text, ....);
- new: const char* CalcWordWrapPosition (float size, const char* text, ....);
The leading 'float scale' parameters was changed to 'float size'.
This was necessary as 'scale' is assuming standard font size which is a concept we aim to
eliminate in an upcoming update. Kept inline redirection function.
- Commented out PushAllowKeyboardFocus()/PopAllowKeyboardFocus() which was obsoleted
in 1.89.4 (March 2023). (#3092)
- PushAllowKeyboardFocus(bool tab_stop) --> PushItemFlag(ImGuiItemFlags_NoTabStop, !tab_stop);
@@ -63,6 +208,89 @@ Breaking changes:
Other changes:
- Textures: added partial texture update protocol. (#8465, #3761)
- The Renderer Backend needs to set io.BackendFlags |= ImGuiBackendFlags_RendererHasTextures
and handle texture updates requests.
- New structs: ImTextureData, ImTextureRect.
- New enums: ImTextureStatus, ImTextureFormat.
- During its ImGui_ImplXXXX_RenderDrawData() call, the backend can now access a texture list
in ImDrawData::Textures[]. Textures may have four distinct states:
- ImTextureStatus_WantCreate: requesting backend to create a texture.
- ImTextureStatus_WantUpdates: requesting backend to copy given blocks from the CPU side
copy of the texture to your graphics pipeline.
A 'tex->Updates[]' list of update is provided as well as a single 'tex->UpdatesRect' bounding box.
- ImTextureStatus_WantDestroy: requesting backend to destroy the texture.
- A 'int UnusedFrames' value is provided to conveniently defer destroying.
- Backend is generally free to destroy textures whenever they like.
- ImTextureStatus_OK: nothing to do.
- Almost all standard backends have been updated to support this.
- Backends have allowed to destroy textures at any time if they desire so.
A list is available in platform_io.Textures[] for this purpose and for backend shutdown.
- Both stb_truetype and FreeType backends have been updated to work with the new
system, and they now share more code than before.
- Added '#define IMGUI_HAS_TEXTURES' to facilitate compile-time checks for third-party
extensions until this is merged with a definitive version number to check.
- Fonts: font backend/loader may easily be changed dynamically, allowing users to compare
rasterizers outputs and features. imgui_freetype is generally beneficial.
- Fonts: ImFontAtlas::AddFontXXX() functions may be called at any time during the frame.
- Fonts: ImFontAtlas::AddFontXXX() can fail more gracefully if error handling is configured
to not assert (this will be better exposed via future font flags).
- Fonts: added ImGui::PushFontSize()/PopFontSize() functions.
- Fonts: added style.FontScaleBase scaling factor (previously called io.FontGlobalScale).
- Fonts: added style.FontScaleDpi scaling factor. This is designed to be be changed on
per-monitor/per-viewport basis, which `io.ConfigDpiScaleFonts` does automatically.
(which is why it is separate from FontScaleBase).
- Fonts: added optional font_size parameter to ImGui::PushFont() function.
- Fonts: added ImFontAtlas::RemoveFont() function.
- Fonts: added ImFontAtlas::CompactCache() function.
- Fonts: added ImFontAtlas::TexDesiredFormat field (default to ImTextureFormat_RGBA32,
can be changed to ImTextureFormat_Alpha8).
- Fonts: added ImFontAtlas::TexMinWidth, TexMinHeight, TexMaxWidth, TexMaxHeight fields.
- Fonts: added ImFontConfig::PixelSnapV to align scaled GlyphOffset.y to pixel boundaries.
- Fonts: added ImFontConfig::GlyphExcludeRanges[], which behave similarly to
ImFontConfig::GlyphRanges[], but has the opposite meaning. It is tailored to situations
where merged fonts have overlapping characters.
- Fonts: added "Input Glyphs Overlap Detection Tool" which dumps a list of glyphs
provided by merged sources, which may help setting up a GlyphExcludeRanges[] filter.
- Fonts: added ImFontAtlas::FontBackendName (which is surfaced in the "About Dear ImGui"
window and other locations).
- Fonts: added ImFontFlags (currently needs to be passed through ImFontConfig until
we revamp font loading API):
- ImFontFlags_DefaultToLegacySize: for legacy compatibility: make PushFont() calls
without explicit size use font->LegacySize instead of current font size.
- ImFontFlags_NoLoadError: disable erroring/assert when calling AddFontXXX()
with missing file/data. Calling code is expected to check AddFontXXX() return value.
- ImFontFlags_NoLoadGlyphs: disable loading new glyphs.
- ImFontFlags_LockBakedSizes: disable loading new baked sizes, disable garbage
collecting current ones. e.g. if you want to lock a font to a single size.
- Fonts: the general design has changed toward meaning that a ImFont doesn't have
have a specific size: it may be bound and drawn with any size.
- We store ImFontBaked structures internally, which are a cache of information
for a given size being drawn. You should not need to deal with ImFontBaked directly.
- ImFontBaked structures may be cleaned up between frames when unused, pointers
to them are only valid for the current frame.
- Added ImFontBaked::IsGlyphLoaded() function.
- Fonts: custom rect packing has generally been reworked. (#8107, #7962, #1282)
- ImFontAtlas::AddCustomRect() (previously AddCustomRectRegular()/AddCustomRectFontGlyph())
functions will immediately return a packed rectangle identifier, and you can write your
pixels immediately - previously had to wait for Build() to be called.
This is also the case when using a legacy backend.
- Custom packed rectangles may be moved during a texture change, aka practically anytime.
Always refer to latest uvs/position returned by GetCustomRect().
- AddCustomRect() returns ImFontAtlasRectId_Invalid on failure.
- Added ImFontAtlas::RemoveCustomRect() function.
- GetCustomRect() can safely return false and not crash when passed an invalid or removed id.
- Fonts: texture is now stored in a single format CPU side (save ~25% when using RGBA).
- Fonts: changing current font to one from a different atlas is supported. (#8080)
- Fonts: automatic baking of an "..." ellipsis works better with monospace fonts.
- Fonts: each ImFontConfig font source may provide a custom backend/loader.
- Fonts: added platform_io.Renderer_TextureMaxWidth/Renderer_TextureMaxHeight fields
for Renderer Backend to specify if there is a maximum accepted texture size (not yet used).
- Fonts: added compile-time overridable '#define ImTextureID_Invalid 0' if you need 0
to be a valid low-level texture identifier.
- Debug Tools: Fonts section: add font preview, add "Remove" button, add "Load all glyphs"
button, add selection to change font backend when both are compiled in.

waiting for the call to ImGui_ImplXXXX_RenderDrawData(). Also useful if you use a staged or
multi-threaded rendering schemes, where you might want to set ImDrawData::Textures = NULL. (#8597, #1860)
- Backends: GLFW: added ImGui_ImplGlfw_GetContentScaleForMonitor(), ImGui_ImplGlfw_GetContentScaleForWindow()
helpers. They are wrappers to glfwGetMonitorContentScale()/glfwGetWindowContentScale(), with compile-time
GLFW version checks + returning 1.0f on Apple platform.
