Changes

This is a followup to v1.89, v1.89.1, v1.89.2, v1.89.3, v1.89.4, v1.89.5, v1.89.6. We are trying to make more frequent releases. Because: some people are relying on tagging and auto-generated bindings for other languages. And: it sets a beat and may encourage teams to update more frequently.

I have been stubbornly deferring tagging 1.90 for while because I wanted to include the range-select feature in it, but it's not done... But there are about 540 lines of changelog between 1.89 and 1.89.7.

Breaking Changes:

  • Moved io.HoverDelayShort/io.HoverDelayNormal to style.HoverDelayShort/style.HoverDelayNormal. As the fields were added in 1.89 and expected to be left unchanged by most users, or only tweaked once during app initialization, we are exceptionally accepting the breakage. Majority of users are likely to not even notice.
  • Overlapping items: (#6512, #3909, #517)
    • Obsoleted SetItemAllowOverlap(): it didn't and couldn't work reliably since 1.89 (2022-11-15), and relied on ambiguously defined design. Use SetNextItemAllowOverlap() before item instead.
    • Added SetNextItemAllowOverlap() (called before an item) as a replacement for using SetItemAllowOverlap() (called after an item). This is roughly equivalent to using the legacy SetItemAllowOverlap() call (public API) + ImGuiButtonFlags_AllowOverlap (internal).
    • Renamed 'ImGuiTreeNodeFlags_AllowItemOverlaptoImGuiTreeNodeFlags_AllowOverlap` for consistency.
    • Renamed ImGuiSelectableFlags_AllowItemOverlap to ImGuiSelectableFlags_AllowOverlap for consistency.
    • Kept redirecting enums (will obsolete).

Other Changes:

  • Tooltips/IsItemHovered() related changes:
    • Tooltips: Added SetItemTooltip() and BeginItemTooltip() helper functions.
      They are shortcuts for the common idiom of using IsItemHovered().
      • SetItemTooltip("Hello") == if (IsItemHovered(ImGuiHoveredFlags_Tooltip)) { SetTooltip("Hello"); }
      • BeginItemTooltip() == IsItemHovered(ImGuiHoveredFlags_Tooltip) && BeginTooltip()
        The newly added ImGuiHoveredFlags_Tooltip is meant to facilitate standardizing mouse hovering delays and rules for a given application. The previously common idiom of using 'if (IsItemHovered()) { SetTooltip(...); }' won't use delay or stationary test.
    • IsItemHovered: Added ImGuiHoveredFlags_Stationary to require mouse being stationary when hovering a new item. Added style.HoverStationaryDelay (~0.15 sec). Once the mouse has been stationary once the state is preserved for same item. (#1485)
    • IsItemHovered: Added ImGuiHoveredFlags_ForTooltip as a shortcut for pulling flags from style.HoverFlagsForTooltipMouse or style.HoverFlagsForTooltipNav depending on active inputs. (#1485)
      • style.HoverFlagsForTooltipMouse defaults to ImGuiHoveredFlags_Stationary | ImGuiHoveredFlags_DelayShort.
      • style.HoverFlagsForTooltipNav defaults to ImGuiHoveredFlags_NoSharedDelay | ImGuiHoveredFlags_DelayNormal.
    • Tooltips: Tweak default offset for non-drag and drop tooltips so underlying items isn't covered as much. (Match offset for drag and drop tooltips)
    • IsItemHovered: Tweaked default value of style.HoverDelayNormal from 0.30 to 0.40, Tweaked default value of style.HoverDelayShort from 0.10 to 0.15. (#1485)
    • IsItemHovered: Added ImGuiHoveredFlags_AllowWhenOverlappedByWindow to ignore window-overlap only. Option ImGuiHoveredFlags_AllowWhenOverlapped now expand into a combination of both _AllowWhenOverlappedByWindow + _AllowWhenOverlappedByItem, matching old behavior.
  • Overlapping items: (#6512, #3909, #517)
    • Most item types should now work with SetNextItemAllowOverlap(). (#6512, #3909, #517)
    • Fixed first frame of an overlap highlighting underlying item if previous frame didn't hover anything.
    • IsItemHovered: Changed to return false when querying an item using AllowOverlap mode which is being overlapped. Added ImGuiHoveredFlags_AllowWhenOverlappedByItem to opt-out. (#6512, #3909, #517)
    • Selectable, TreeNode: When using ImGuiSelectableFlags_AllowOverlap/ImGuiTreeNodeFlags_AllowOverlap and holding item held, overlapping widgets won't appear as hovered. (#6512, #3909)
  • IsWindowHovered: Added support for ImGuiHoveredFlags_Stationary.
  • IsWindowHovered, IsItemHovered: Assert when passed any unsupported flags.
  • Tables: Fixed a regression in 1.89.6 leading to the first column of tables with either ScrollX or ScrollY flags from being impossible to resize. (#6503)
  • CollapsingHeader/TreeNode: Fixed text padding when using _Framed+_Leaf flags. (#6549) [@BobbyAnguelov]
  • InputText: Fixed not returning true when buffer is cleared while using the ImGuiInputTextFlags_EscapeClearsAll flag. (#5688, #2620)
  • InputText: Fixed a crash on deactivating a ReadOnly buffer. (#6570, #6292, #4714)
  • InputText: ImGuiInputTextCallbackData::InsertChars() accept (NULL,NULL) range, in order to conform to common idioms (e.g. passing .data(), .data() + .size() from a null string). (#6565, #6566, #3615)
  • Combo: Made simple/legacy Combo() function not returns true when picking already selected item. This is consistent with other widgets. If you need something else, you can use BeginCombo(). (#1182)
  • Clipper: Rework inner logic to allow functioning with a zero-clear constructor. This is order to facilitate usage for language bindings (e.g cimgui or dear_binding) where user may not be calling a constructor manually. (#5856)
  • Drag and Drop: Apply default behavior of drag source not reporting itself as hovered at lower-level, so DragXXX, SliderXXX, InputXXX, Plot widgets are fulfilling it. (Behavior doesn't apply when ImGuiDragDropFlags_SourceNoDisableHover is set).
  • Modals: In the case of nested modal, made sure that focused or appearing windows are moved below the lowest blocking modal (rather than the highest one). (#4317)
  • GetKeyName(): Fixed assert with ImGuiMod_XXX values when IMGUI_DISABLE_OBSOLETE_KEYIO is set.
  • Debug Tools: Added io.ConfigDebugIniSettings option to save .ini data with extra comments. Currently mainly for inspecting Docking .ini data, but makes saving slower.
  • Demo: Added more developed Widgets->Tooltips section. (#1485)
  • Backends: OpenGL3: Fixed support for glBindSampler() backup/restore on ES3. (#6375, #6508) [@jsm174]
  • Backends: OpenGL3: Fixed erroneous use glGetIntegerv(GL_CONTEXT_PROFILE_MASK) on contexts lower than 3.2. (#6539, #6333) [@krumelmonster]
  • Backends: Vulkan: Added optional support for VK_KHR_dynamic_rendering (Vulkan 1.3+) in the backend, for applications using it. User needs to set init_info->UseDynamicRendering = true and init_info->ColorAttachmentFormat. RenderPass becomes unused. (#5446, #5037) [@spnda, @cmarcelo]
  • Backends: GLFW: Accept glfwGetTime() not returning a monotonically increasing value. This seems to happens on some Windows setup when peripherals disconnect, and is likely to also happen on browser+Emscripten. Matches similar 1.89.4 fix in SDL backend. (#6491)
  • Examples: Win32+OpenGL3: Changed DefWindowProc() to DefWindowProcW() to match other examples
    and support the example app being compiled without UNICODE. (#6516, #5725, #5961, #5975) [@yenixing]

Changes from 1.89.6 to 1.89.7 related to the docking branch (multi-viewport and docking features):

  • Viewports+Docking: Fixed extraneous viewport+platform-window recreation in various combination of showing or hiding windows, docking with/without split, undocking. While with some backends and without OS decorations, some extraneous window recreation were visibly not noticeable, they would typically become noticeable when enabling OS decorations on those windows (e.g. Windows title bar fade-in/animation).
  • Viewports: Closing a viewport via OS/platform means (e.g. OS close button or task-bar menu), mark all windows in this viewport as closed.
  • Docking: Fixed one-frame flickering on reappearing windows binding to a dock node where a later-submitted window was already bound.
  • Docking: Fixed dragging from title-bar empty space (regression from 1.88 related to keeping ID alive when calling low-level ButtonBehavior() directly). (#5181, #2645)
  • Docking: [Internal] DockBuilderDockWindow() API calls don't clear docking order if the target node is same as existing one.
  • Backends: Win32: Added support for changing ParentViewportID after viewport creation.

Changes from 1.89.6 to 1.89.7 related to the range-select branch: (aimed to finish, apply some api changes and merge in 1.90):

  • RangeSelect/MultiSelect: (BREAKING) In ImGuiMultiSelectIO, renamed "RangeSrc" -> "RangeSrcItem", "RangeDst" -> "RangeDstItem". "RangeValue" -> "RangeSelected". This is designed to make things more consistent with upcoming features and polish/merge of the branch.
  • RangeSelect/MultiSelect: Removed the need for polling IsItemToggledSelection() and toggling per-item selection. This can now be completely handled by the BeginMultiSelect() and EndMultiSelect() requests.
  • RangeSelect/MultiSelect: Removed ImGuiMultiSelectFlags_NoUnselect because I currently can't find use for this specific design.
  • RangeSelect/MultiSelect: Update various comments. Simplified/tidied up internal code.

New exciting projects!

@RorySoh: "Nin Online is an MMORPG that started development in 2013 and launched in 2017 built with a Visual Basic 6 engine. In recent years, we ported the game to C# with .NET Framework. Now, we're using .NET 6 and all our UI systems have been replaced with just ImGui (We had 6 separate systems, including WinForms for our in-game editor suite). The HUD and every UI piece in the screen is also ImGui. There's actually a lot more cool stuff in the game, like animated UI elements that are done in ImGui. Performance has been amazing too."
