Added IsItemDeactivatedAfterChange() if the last item was active previously, isn't anymore, and during its active state modified a value. Note that you may still get false positive. (#820, #956, #1875)

Internals: Added GetItemID(), GetFocusID() for consistency. Made GetActiveID() inline. Comments, fixed typos, demo tweaks.

Added IsItemDeactivated() to query if the last item was active previously but isn't anymore. Useful for Undo/Redo patterns. (#820, #956, #1875)

Comments

Nav: Added support for PageUp/PageDown (explorer-style: first aim at bottom/top most item, when scroll a page worth of contents). (#787)

Internals: Nav: Removed ParentID from move result (unused, would need to be full-filled for PageUp/PageDown code) + FAQ typo fix.

Internals: Reintroducing LastActiveIdTimer because it is useful and to reduce merge conflicts. (#1537)

Internals: Added BeginDragDropTooltip() internal function to convey semantic (drag and drop tooltip doesn't get clipped within display boundaries). Revert part of 3218666. (#1739, #143).

Added ImGuiDragDropFlags_AcceptNoPreviewTooltip flag to disable drag source tooltip from the target site (#143)

Remove trailing white spaces.

Internals: Forward declaring and commenting internal structures. Renamed ImGuiDrawContext to ImGuiWindowTempData, but kept .DC member name for backward compatibility purpose

Comments + Internals: Selectable: decoupled internal flags and removed their menu / menu-item semantic as upcoming changes are requiring more flexibility.

Nav: Draft internal api to forward move request with loop/wrap options. Will rework for parallel scoring of two paths (as a generalization of the NavFlattened concept). (#787)

Version 1.62 WIP

Version 1.61 + todo additions

Fix for atof with glibc.

Added ImAtof, ImCeil, ImFloorStd to IMGUI_DISABLE_MATH_FUNCTIONS for consistency. Configuration comments.

Added IMGUI_DISABLE_MATH_FUNCTIONS in imconfig.h to make it slightly easier to redefine wrappers to std maths functions such as fabsf(), fmodf(), etc. Comments.

Data types: DragScalar, InputScalar: default parameters. Added IM_STATIC_ASSERT(). Comments.

Merge branch 'data_types' ...

# Conflicts:
#	CHANGELOG.txt
#	imgui.cpp

Internals: Made ContentsRegionRect absolute to reduce confusion. Renamed InnerRect to InnerMainRect, renamed WindowRectClipper to OuterRectClipped.

Internals: Nav: Extracted code into a NavClampToVisibleAreaForMoveDir() + fix debug code + inline some functions, removed obsolete EndChild() comment.

Internals: Declaring DragBehavior, SliderBehavior in there (no warantee given) as they may be useful to custom widgets.

Moved DragScalar, InputScalar, SliderScalar to imgui.h as well as ImGuiDataType (#320, #643, #708, #1011)

Settings: Added LoadIniSettingsFromDisk(), LoadIniSettingsFromMemory(), SaveIniSettingsToDisk(), SaveIniSettingsToMemory(), io.WantSaveIniSettings. (#923, #993)

Internals: Removed unnecessary allocation indirection for g.LogClipboard (this only made sense when there was a global context instance)

SliderScalar, VSliderScalar(): Support for any data types. Tested with various ranges/limits. Note that Drag/Slider/Input currently fail if the format string doesn't preview the actual value. Will fix next. (#320, #643, #708, #1011)

Internals: A few selected math helpers are now using template to handle all supported types. Added ImPow() to wrap float/double in a standard manner without calling pow(double) when not needed in Drag code.

Internals: Data types: Made format string optional. DragBehavior: Moved a bit of code outside of the template. Slider tidying up. Removed unnecessary call to fabsf().

Internals: Missing const, some renaming. Tweak legacy fast path.
