Demo: Moved test of the Hovered/Active/Focused functions to the Widgets section.

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

Comments

Comments, changelog

Examples: FreeGLUT: Fixed mapping of Space key. (#801)

Comments, documentation

Examples: FreeGLUT: Added FreeGLUT bindings. Added FreeGLUT+OpenGL2 example. (#801)

Examples: Win32: Fixed handling of mouse wheel messages to support finer position messages (typically sent by track-pads). (#1874)

Examples: Comments to make ImGuiConfigFlags_NoMouseCursorChange more visible (#1027). + Allegro5: Added support for ImGuiConfigFlags_NoMouseCursorChange flag.

Fixed Travis path + various paths in comments/documentations

Examples: Renamed imgui_impl_sdl2.cpp to imgui_impl_sdl.cpp (#1870) + changelog bits

Examples: Renamed example folders. (#1870)

Merge branch 'font_min_max_advance'

Big example binding refactor (manually imported from Viewport branch, stripped out of Viewport code). (#1870) ...

Read examples/README.txt for some details.
ImDrawData: Added DisplayPos, DisplaySize fields honored by all backends (not strictly necessary to honor just now, but doing it to be ahead)

ImFontConfig: Added GlyphMinAdvanceX/GlyphMaxAdvanceX settings useful to make a font appears monospaced, particularly useful for icon fonts. (#1869)

Nav: Addendum: only set io.WantSetMousePos if necessary. (#1867)

Nav: Removed an unnecessary assertion that could fail when using Mouse and Keyboard simultaneously with the NavEnableSetMousePos flag. (#1867)

SliderFloat(): When using keyboard/gamepad and a zero precision format string (e.g. "%.0f"), always step in integer units. (#1866)

Popup: Improved handling of (erroneously) repeating calls to OpenPopup() to not fully close/re-open the popup so its child popups won't get closed. (#1497, #1533, #1865). ...

Followup/fix the change made in deab2ab

Added missing IMGUI_API markers in non-inline section of the IMGUI_DISABLE_OBSOLETE_FUNCTIONS block: old Begin(), InputFloat().

Readme, FAQ tweaks (#1807)

Added GetGlyphRangesChineseSimplifiedCommon() helper that returns a list of ~2500 most common Simplified Chinese characters. Renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set. (#1859) ...

Changed the accumulative encoding to remove the implicit +1 which only saved a little space and made things more confusing.

TreeNodeEx(): The helper ImGuiTreeNodeFlags_CollapsingHeader flag now include ImGuiTreeNodeFlags_NoTreePushOnOpen. The flag was already set by CollapsingHeader(). The only difference is if you were using TreeNodeEx() manually with ImGuiTreeNodeFlags_CollapsingHeader and without ImGuiTreeNodeFlags_NoTreePushOnOpen. In which case you can remove the ImGuiTreeNodeFlags_NoTreePushOnOpen flag from your call (ImGuiTreeNodeFlags_CollapsingHeader & ~ImGuiTreeNodeFlags_NoTreePushOnOpen). (#1864)

stb_textedit, InputText(): Fixed Undo after pasting large amount of text (Redo will still fail when undo buffers are exhausted, but text won't be corrupted). ...

See issue 620 in nothings/stb/

Updated stb_textedit 1.09 + patches --> 1.12 + minor patches. (#715)

InputTextMultiline(): Fixed double navigation highlight when scrollbar is active. (#787)

Nav: Fixed clipped scoring when exiting a NavFlattened child back to a parent item (clipping not desirable then). (followup and fix to c665c15). (#787)

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

Changelog formatting update, Todo, comments. Tweak Child demo. Shuffle some code in NavUpdate().

Nav: When entering into a NavFlattened child we only consider the visible items for scoring (note that this only work assuming the NavFlattened child window has interactive items). Fixes accidentally hoping into a NavFlattened child. (#767)
