// ID stack/scopes
// Read the FAQ (docs/FAQ.md or http://dearimgui.org/faq) for more details about how ID are handled in dear imgui.
// - Those questions are answered and impacted by understanding of the ID stack system:
// - "Q: Why is my widget not reacting when I click on it?"
// - "Q: How can I have widgets with an empty label?"
// - "Q: How can I have multiple widgets with the same label?"
// - Short version: ID are hashes of the entire ID stack. If you are creating widgets in a loop you most likely
// want to push a unique identifier (e.g. object pointer, loop index) to uniquely differentiate them.
// - You can also use the "Label##foobar" syntax within widget label to distinguish them from each others.
// - In this header file we use the "label"/"name" terminology to denote a string that will be displayed + used as an ID,
// whereas "str_id" denote a string that is only used as an ID and not normally displayed.
IMGUI_APIvoidPushID(constchar*str_id);// push string into the ID stack (will hash string).

IMGUI_APIvoidTextUnformatted(constchar*text,constchar*text_end=NULL);// raw text without formatting. Roughly equivalent to Text("%s", text) but: A) doesn't require null terminated string if 'text_end' is specified, B) it's faster, no memory copy is done, no buffer size limits, recommended for long chunks of text.
IMGUI_APIvoidText(constchar*fmt,...)IM_FMTARGS(1);// formatted text
IMGUI_APIvoidTextWrapped(constchar*fmt,...)IM_FMTARGS(1);// shortcut for PushTextWrapPos(0.0f); Text(fmt, ...); PopTextWrapPos();. Note that this won't work on an auto-resizing window if there's no other widgets to extend the window width, yoy may need to set a size using SetNextWindowSize().

// the array syntax is just a way to document the number of elements that are expected to be accessible. You can pass address of your first element out of a contiguous set, e.g. &myvector.x
// - Adjust format string to decorate the value with a prefix, a suffix, or adapt the editing and display precision e.g. "%.3f" -> 1.234; "%5.2f secs" -> 01.23 secs; "Biscuit: %.0f" -> Biscuit: 1; etc.
// - Format string may also be set to NULL or use the default format ("%f" or "%d").
// - Speed are per-pixel of mouse movement (v_speed=0.2f: mouse needs to move by 5 pixels to increase value by 1). For gamepad/keyboard navigation, minimum speed is Max(v_speed, minimum_step_at_given_precision).
// - Use v_min < v_max to clamp edits to given limits. Note that CTRL+Click manual input can override those limits if ImGuiSliderFlags_AlwaysClamp is not used.
// - Use v_max = FLT_MAX / INT_MAX etc to avoid clamping to a maximum, same with v_min = -FLT_MAX / INT_MIN to avoid clamping to a minimum.
// - We use the same sets of flags for DragXXX() and SliderXXX() functions as the features are the same and it makes it easier to swap them.
// - Legacy: Pre-1.78 there are DragXXX() function signatures that take a final `float power=1.0f' argument instead of the `ImGuiSliderFlags flags=0' argument.

// Widgets: Color Editor/Picker (tip: the ColorEdit* functions have a little color square that can be left-clicked to open a picker, and right-clicked to open an option menu.)
// - Note that in C++ a 'float v[X]' function argument is the _same_ as 'float* v', the array syntax is just a way to document the number of elements that are expected to be accessible.

IMGUI_APIboolColorButton(constchar*desc_id,constImVec4&col,ImGuiColorEditFlagsflags=0,constImVec2&size=ImVec2(0,0));// display a color square/button, hover for details, return true when pressed.
IMGUI_APIvoidSetColorEditOptions(ImGuiColorEditFlagsflags);// initialize current options (generally on application startup) if you want to select a default format, picker type, etc. User will be able to change many settings, unless you pass the _NoOptions flag to your calls.

IMGUI_APIboolTreeNode(constchar*label);
IMGUI_APIboolTreeNode(constchar*str_id,constchar*fmt,...)IM_FMTARGS(2);// helper variation to easily decorelate the id from the displayed string. Read the FAQ about why and how to use ID. to align arbitrary text at the same level as a TreeNode() you can use Bullet().
IMGUI_APIvoidTreePush(constchar*str_id);// ~ Indent()+PushId(). Already called by TreeNode() when returning true, but you can call TreePush/TreePop yourself if desired.
IMGUI_APIvoidTreePush(constvoid*ptr_id);// "
IMGUI_APIvoidTreePop();// ~ Unindent()+PopId()
IMGUI_APIfloatGetTreeNodeToLabelSpacing();// horizontal distance preceding label when using TreeNode*() or Bullet() == (g.FontSize + style.FramePadding.x*2) for a regular unframed TreeNode

IMGUI_APIboolCollapsingHeader(constchar*label,bool*p_visible,ImGuiTreeNodeFlagsflags=0);// when 'p_visible != NULL': if '*p_visible==true' display an additional small close button on upper right of the header which will set the bool to false when clicked, if '*p_visible==false' don't display the header.
IMGUI_APIvoidSetNextItemOpen(boolis_open,ImGuiCondcond=0);// set next TreeNode/CollapsingHeader open state.
// Widgets: Selectables
// - A selectable highlights when hovered, and can display another color when selected.
// - Neighbors selectable extend their highlight bounds in order to leave no gap between them. This is so a series of selected Selectable appear contiguous.
IMGUI_APIboolSelectable(constchar*label,boolselected=false,ImGuiSelectableFlagsflags=0,constImVec2&size=ImVec2(0,0));// "bool selected" carry the selection state (read-only). Selectable() is clicked is returns true so you can modify your selection state. size.x==0.0: use remaining width, size.x>0.0: specify width. size.y==0.0: use label height, size.y>0.0: specify height
IMGUI_APIboolSelectable(constchar*label,bool*p_selected,ImGuiSelectableFlagsflags=0,constImVec2&size=ImVec2(0,0));// "bool* p_selected" point to the selection state (read-write), as a convenient helper.
// Widgets: List Boxes
// - This is essentially a thin wrapper to using BeginChild/EndChild with some stylistic changes.
// - The BeginListBox()/EndListBox() api allows you to manage your contents and selection state however you want it, by creating e.g. Selectable() or any items.
// - The simplified/old ListBox() api are helpers over BeginListBox()/EndListBox() which are kept available for convenience purpose. This is analoguous to how Combos are created.
// - Choose frame width: size.x > 0.0f: custom / size.x < 0.0f or -FLT_MIN: right-align / size.x = 0.0f (default): use current ItemWidth
// - Choose frame height: size.y > 0.0f: custom / size.y < 0.0f or -FLT_MIN: bottom-align / size.y = 0.0f (default): arbitrary default height which can fit ~7 items
IMGUI_APIboolBeginListBox(constchar*label,constImVec2&size=ImVec2(0,0));// open a framed scrolling region
IMGUI_APIvoidEndListBox();// only call EndListBox() if BeginListBox() returned true!
// - Those are merely shortcut to calling Text() with a format string. Output single value in "name: value" format (tip: freely declare more in your code to handle your types. you can add functions to the ImGui namespace)
IMGUI_APIvoidSetTooltip(constchar*fmt,...)IM_FMTARGS(1);// set a text-only tooltip, typically use with ImGui::IsItemHovered(). override any previous call to SetTooltip().
// - They block normal mouse hovering detection (and therefore most mouse interactions) behind them.
// - If not modal: they can be closed by clicking anywhere outside them, or by pressing ESCAPE.
// - Their visibility state (~bool) is held internally instead of being held by the programmer as we are used to with regular Begin*() calls.
// - The 3 properties above are related: we need to retain popup visibility state in the library because popups may be closed as any time.
// - You can bypass the hovering restriction by using ImGuiHoveredFlags_AllowWhenBlockedByPopup when calling IsItemHovered() or IsWindowHovered().
// - IMPORTANT: Popup identifiers are relative to the current ID stack, so OpenPopup and BeginPopup generally needs to be at the same level of the stack.
// This is sometimes leading to confusing mistakes. May rework this in the future.
// Popups: begin/end functions
// - BeginPopup(): query popup state, if open start appending into the window. Call EndPopup() afterwards. ImGuiWindowFlags are forwarded to the window.
// - BeginPopupModal(): block every interaction behind the window, cannot be closed by user, add a dimming background, has a title bar.
IMGUI_APIboolBeginPopup(constchar*str_id,ImGuiWindowFlagsflags=0);// return true if the popup is open, and you can start outputting to it.
IMGUI_APIboolBeginPopupModal(constchar*name,bool*p_open=NULL,ImGuiWindowFlagsflags=0);// return true if the modal is open, and you can start outputting to it.
IMGUI_APIvoidEndPopup();// only call EndPopup() if BeginPopupXXX() returns true!
// Popups: open/close functions
// - OpenPopup(): set popup state to open. ImGuiPopupFlags are available for opening options.
// - If not modal: they can be closed by clicking anywhere outside them, or by pressing ESCAPE.
// - CloseCurrentPopup(): use inside the BeginPopup()/EndPopup() scope to close manually.
// - CloseCurrentPopup() is called by default by Selectable()/MenuItem() when activated (FIXME: need some options).
// - Use ImGuiPopupFlags_NoOpenOverExistingPopup to avoid opening a popup if there's already one at the same level. This is equivalent to e.g. testing for !IsAnyPopupOpen() prior to OpenPopup().
// - Use IsWindowAppearing() after BeginPopup() to tell if a window just opened.
// - IMPORTANT: Notice that for OpenPopupOnItemClick() we exceptionally default flags to 1 (== ImGuiPopupFlags_MouseButtonRight) for backward compatibility with older API taking 'int mouse_button = 1' parameter
IMGUI_APIvoidOpenPopup(constchar*str_id,ImGuiPopupFlagspopup_flags=0);// call to mark popup as open (don't call every frame!).
IMGUI_APIvoidOpenPopup(ImGuiIDid,ImGuiPopupFlagspopup_flags=0);// id overload to facilitate calling from nested stacks
IMGUI_APIvoidOpenPopupOnItemClick(constchar*str_id=NULL,ImGuiPopupFlagspopup_flags=1);// helper to open popup when clicked on last item. Default to ImGuiPopupFlags_MouseButtonRight == 1. (note: actually triggers on the mouse _released_ event to be consistent with popup behaviors)
IMGUI_APIvoidCloseCurrentPopup();// manually close the popup we have begin-ed into.
// Popups: open+begin combined functions helpers
// - Helpers to do OpenPopup+BeginPopup where the Open action is triggered by e.g. hovering an item and right-clicking.
// - They are convenient to easily create context menus, hence the name.
// - IMPORTANT: Notice that BeginPopupContextXXX takes ImGuiPopupFlags just like OpenPopup() and unlike BeginPopup(). For full consistency, we may add ImGuiWindowFlags to the BeginPopupContextXXX functions in the future.
// - IMPORTANT: Notice that we exceptionally default their flags to 1 (== ImGuiPopupFlags_MouseButtonRight) for backward compatibility with older API taking 'int mouse_button = 1' parameter, so if you add other flags remember to re-add the ImGuiPopupFlags_MouseButtonRight.
IMGUI_APIboolBeginPopupContextItem(constchar*str_id=NULL,ImGuiPopupFlagspopup_flags=1);// open+begin popup when clicked on last item. Use str_id==NULL to associate the popup to previous item. If you want to use that on a non-interactive item such as Text() you need to pass in an explicit ID here. read comments in .cpp!
IMGUI_APIboolBeginPopupContextWindow(constchar*str_id=NULL,ImGuiPopupFlagspopup_flags=1);// open+begin popup when clicked on current window.
IMGUI_APIboolBeginPopupContextVoid(constchar*str_id=NULL,ImGuiPopupFlagspopup_flags=1);// open+begin popup when clicked in void (where there are no windows).
// Popups: query functions
// - IsPopupOpen(): return true if the popup is open at the current BeginPopup() level of the popup stack.
// - IsPopupOpen() with ImGuiPopupFlags_AnyPopupId: return true if any popup is open at the current BeginPopup() level of the popup stack.
// - IsPopupOpen() with ImGuiPopupFlags_AnyPopupId + ImGuiPopupFlags_AnyPopupLevel: return true if any popup is open.
IMGUI_APIboolIsPopupOpen(constchar*str_id,ImGuiPopupFlagsflags=0);// return true if the popup is open.
// Tables
// - Full-featured replacement for old Columns API.
// - See Demo->Tables for demo code. See top of imgui_tables.cpp for general commentary.
// - See ImGuiTableFlags_ and ImGuiTableColumnFlags_ enums for a description of available flags.
// The typical call flow is:
// - 1. Call BeginTable(), early out if returning false.
// - 2. Optionally call TableSetupColumn() to submit column name/flags/defaults.
// - 3. Optionally call TableSetupScrollFreeze() to request scroll freezing of columns/rows.
// - 4. Optionally call TableHeadersRow() to submit a header row. Names are pulled from TableSetupColumn() data.
// - 5. Populate contents:
// - In most situations you can use TableNextRow() + TableSetColumnIndex(N) to start appending into a column.
// - If you are using tables as a sort of grid, where every column is holding the same type of contents,
// you may prefer using TableNextColumn() instead of TableNextRow() + TableSetColumnIndex().
// TableNextColumn() will automatically wrap-around into the next row if needed.
// - IMPORTANT: Comparatively to the old Columns() API, we need to call TableNextColumn() for the first column!
IMGUI_APIvoidEndTable();// only call EndTable() if BeginTable() returns true!
IMGUI_APIvoidTableNextRow(ImGuiTableRowFlagsrow_flags=0,floatmin_row_height=0.0f);// append into the first cell of a new row.
IMGUI_APIboolTableNextColumn();// append into the next column (or first column of next row if currently in last column). Return true when column is visible.
IMGUI_APIboolTableSetColumnIndex(intcolumn_n);// append into the specified column. Return true when column is visible.
// Tables: Headers & Columns declaration
// - Use TableSetupColumn() to specify label, resizing policy, default width/weight, id, various other flags etc.
// - Use TableHeadersRow() to create a header row and automatically submit a TableHeader() for each column.
// Headers are required to perform: reordering, sorting, and opening the context menu.
// The context menu can also be made available in columns body using ImGuiTableFlags_ContextMenuInBody.
// - You may manually submit headers using TableNextRow() + TableHeader() calls, but this is only useful in
// some advanced use cases (e.g. adding custom widgets in header row).
// - Use TableSetupScrollFreeze() to lock columns/rows so they stay visible when scrolled.
IMGUI_APIvoidTableSetupScrollFreeze(intcols,introws);// lock columns/rows so they stay visible when scrolled.
IMGUI_APIvoidTableHeadersRow();// submit all headers cells based on data provided to TableSetupColumn() + submit context menu
IMGUI_APIvoidTableHeader(constchar*label);// submit one header cell manually (rarely used)
// Tables: Sorting & Miscellaneous functions
// - Sorting: call TableGetSortSpecs() to retrieve latest sort specs for the table. NULL when not sorting.
// When 'sort_specs->SpecsDirty == true' you should sort your data. It will be true when sorting specs have
// changed since last call, or the first time. Make sure to set 'SpecsDirty = false' after sorting,
// else you may wastefully sort your data every frame!
// - Functions args 'int column_n' treat the default value of -1 as the same as passing the current column index.
IMGUI_APIImGuiTableSortSpecs*TableGetSortSpecs();// get latest sort specs for the table (NULL if not sorting). Lifetime: don't hold on this pointer over multiple frames or past any subsequent call to BeginTable().
IMGUI_APIintTableGetColumnCount();// return number of columns (value passed to BeginTable)
IMGUI_APIintTableGetColumnIndex();// return current column index.
IMGUI_APIintTableGetRowIndex();// return current row index.
IMGUI_APIconstchar*TableGetColumnName(intcolumn_n=-1);// return "" if column didn't have a name declared by TableSetupColumn(). Pass -1 to use current column.
IMGUI_APIImGuiTableColumnFlagsTableGetColumnFlags(intcolumn_n=-1);// return column flags so you can query their Enabled/Visible/Sorted/Hovered status flags. Pass -1 to use current column.
IMGUI_APIvoidTableSetColumnEnabled(intcolumn_n,boolv);// change user accessible enabled/disabled state of a column. Set to false to hide the column. User can use the context menu to change this themselves (right-click in headers, or right-click in columns body with ImGuiTableFlags_ContextMenuInBody)
IMGUI_APIvoidTableSetBgColor(ImGuiTableBgTargettarget,ImU32color,intcolumn_n=-1);// change the color of a cell, row, or column. See ImGuiTableBgTarget_ flags for details.
// Legacy Columns API (prefer using Tables!)
// - You can also use SameLine(pos_x) to mimic simplified columns.
IMGUI_APIvoidNextColumn();// next column, defaults to current row or next row if the current row is finished
IMGUI_APIintGetColumnIndex();// get current column index
IMGUI_APIfloatGetColumnWidth(intcolumn_index=-1);// get column width (in pixels). pass -1 to use current column
IMGUI_APIvoidSetColumnWidth(intcolumn_index,floatwidth);// set column width (in pixels). pass -1 to use current column
IMGUI_APIfloatGetColumnOffset(intcolumn_index=-1);// get position of column line (in pixels, from the left side of the contents region). pass -1 to use current column, otherwise 0..GetColumnsCount() inclusive. column 0 is typically 0.0f
IMGUI_APIvoidSetColumnOffset(intcolumn_index,floatoffset_x);// set position of column line (in pixels, from the left side of the contents region). pass -1 to use current column
IMGUI_APIboolBeginTabBar(constchar*str_id,ImGuiTabBarFlagsflags=0);// create and append into a TabBar
IMGUI_APIvoidEndTabBar();// only call EndTabBar() if BeginTabBar() returns true!
IMGUI_APIboolBeginTabItem(constchar*label,bool*p_open=NULL,ImGuiTabItemFlagsflags=0);// create a Tab. Returns true if the Tab is selected.
IMGUI_APIvoidEndTabItem();// only call EndTabItem() if BeginTabItem() returns true!
IMGUI_APIboolTabItemButton(constchar*label,ImGuiTabItemFlagsflags=0);// create a Tab behaving like a button. return true when clicked. cannot be selected in the tab bar.
IMGUI_APIvoidSetTabItemClosed(constchar*tab_or_docked_window_label);// notify TabBar or Docking system of a closed tab/window ahead (useful to reduce visual flicker on reorderable tab bars). For tab-bar: call after BeginTabBar() and before Tab submissions. Otherwise call with a window name.
// Logging/Capture
// - All text output from the interface can be captured into tty/file/clipboard. By default, tree nodes are automatically opened during logging.
IMGUI_APIvoidLogToTTY(intauto_open_depth=-1);// start logging to tty (stdout)
IMGUI_APIvoidLogToFile(intauto_open_depth=-1,constchar*filename=NULL);// start logging to file
IMGUI_APIvoidLogToClipboard(intauto_open_depth=-1);// start logging to OS clipboard
// - On source items, call BeginDragDropSource(), if it returns true also call SetDragDropPayload() + EndDragDropSource().
// - On target candidates, call BeginDragDropTarget(), if it returns true also call AcceptDragDropPayload() + EndDragDropTarget().
// - If you stop calling BeginDragDropSource() the payload is preserved however it won't have a preview tooltip (we currently display a fallback "..." tooltip, see #1725)
// - An item can be both drag source and drop target.
IMGUI_APIboolBeginDragDropSource(ImGuiDragDropFlagsflags=0);// call after submitting an item which may be dragged. when this return true, you can call SetDragDropPayload() + EndDragDropSource()
IMGUI_APIboolSetDragDropPayload(constchar*type,constvoid*data,size_tsz,ImGuiCondcond=0);// type is a user defined string of maximum 32 characters. Strings starting with '_' are reserved for dear imgui internal types. Data is copied and held by imgui. Return true when payload has been accepted.
IMGUI_APIvoidEndDragDropSource();// only call EndDragDropSource() if BeginDragDropSource() returns true!
IMGUI_APIboolBeginDragDropTarget();// call after submitting an item that may receive a payload. If this returns true, you can call AcceptDragDropPayload() + EndDragDropTarget()
IMGUI_APIconstImGuiPayload*AcceptDragDropPayload(constchar*type,ImGuiDragDropFlagsflags=0);// accept contents of a given type. If ImGuiDragDropFlags_AcceptBeforeDelivery is set you can peek into the payload before the mouse button is released.
IMGUI_APIvoidEndDragDropTarget();// only call EndDragDropTarget() if BeginDragDropTarget() returns true!
IMGUI_APIconstImGuiPayload*GetDragDropPayload();// peek directly into the current payload from anywhere. may return NULL. use ImGuiPayload::IsDataType() to test for the payload type.
// Disabling [BETA API]
// - Disable all user interactions and dim items visuals (applying style.DisabledAlpha over current colors)
// - Those can be nested but it cannot be used to enable an already disabled section (a single BeginDisabled(true) in the stack is enough to keep everything disabled)
// - BeginDisabled(false) essentially does nothing useful but is provided to facilitate use of boolean expressions. If you can avoid calling BeginDisabled(False)/EndDisabled() best to avoid it.
IMGUI_APIvoidBeginDisabled(booldisabled=true);
IMGUI_APIvoidEndDisabled();
// Clipping
// - Mouse hovering is affected by ImGui::PushClipRect() calls, unlike direct calls to ImDrawList::PushClipRect() which are render only.
// - Prefer using "SetItemDefaultFocus()" over "if (IsWindowAppearing()) SetScrollHereY()" when applicable to signify "this is the default item"
IMGUI_APIvoidSetItemDefaultFocus();// make last item the default focused item of a window.
IMGUI_APIvoidSetKeyboardFocusHere(intoffset=0);// focus keyboard on the next widget. Use positive 'offset' to access sub components of a multiple component widget. Use -1 to access previous widget.
// Item/Widgets Utilities and Query Functions
// - Most of the functions are referring to the previous Item that has been submitted.
// - See Demo Window under "Widgets->Querying Status" for an interactive visualization of most of those functions.
IMGUI_APIboolIsItemHovered(ImGuiHoveredFlagsflags=0);// is the last item hovered? (and usable, aka not blocked by a popup, etc.). See ImGuiHoveredFlags for more options.

IMGUI_APIboolIsItemFocused();// is the last item focused for keyboard/gamepad navigation?
IMGUI_APIboolIsItemClicked(ImGuiMouseButtonmouse_button=0);// is the last item hovered and mouse clicked on? (**) == IsMouseClicked(mouse_button) && IsItemHovered()Important. (**) this is NOT equivalent to the behavior of e.g. Button(). Read comments in function definition.
IMGUI_APIboolIsItemVisible();// is the last item visible? (items may be out of sight because of clipping/scrolling)
IMGUI_APIboolIsItemEdited();// did the last item modify its underlying value this frame? or was pressed? This is generally the same as the "bool" return value of many widgets.
IMGUI_APIboolIsItemActivated();// was the last item just made active (item was previously inactive).
IMGUI_APIboolIsItemDeactivated();// was the last item just made inactive (item was previously active). Useful for Undo/Redo patterns with widgets that require continuous editing.
IMGUI_APIboolIsItemDeactivatedAfterEdit();// was the last item just made inactive and made a value change when it was active? (e.g. Slider/Drag moved). Useful for Undo/Redo patterns with widgets that require continuous editing. Note that you may get false positives (some widgets such as Combo()/ListBox()/Selectable() will return true even when clicking an already selected item).
IMGUI_APIboolIsItemToggledOpen();// was the last item open state toggled? set by TreeNode().
IMGUI_APIboolIsAnyItemHovered();// is any item hovered?

IMGUI_APIImVec2GetItemRectSize();// get size of last item
IMGUI_APIvoidSetItemAllowOverlap();// allow last item to be overlapped by a subsequent item. sometimes useful with invisible buttons, selectables, etc. to catch unused area.
// Viewports
// - Currently represents the Platform Window created by the application which is hosting our Dear ImGui windows.
// - In 'docking' branch with multi-viewport enabled, we extend this concept to have multiple active viewports.
// - In the future we will extend this concept further to also represent Platform Monitor and support a "no main platform window" operation mode.
IMGUI_APIImGuiViewport*GetMainViewport();// return primary/default viewport. This can never be NULL.
// Background/Foreground Draw Lists
IMGUI_APIImDrawList*GetBackgroundDrawList();// this draw list will be the first rendered one. Useful to quickly draw shapes/text behind dear imgui contents.
IMGUI_APIImDrawList*GetForegroundDrawList();// this draw list will be the last rendered one. Useful to quickly draw shapes/text over dear imgui contents.
// Miscellaneous Utilities
IMGUI_APIboolIsRectVisible(constImVec2&size);// test if rectangle (of given size, starting from cursor position) is visible / not clipped.

IMGUI_APIboolBeginChildFrame(ImGuiIDid,constImVec2&size,ImGuiWindowFlagsflags=0);// helper to create a child window / scrolling region that looks like a normal widget frame
IMGUI_APIvoidEndChildFrame();// always call EndChildFrame() regardless of BeginChildFrame() return values (which indicates a collapsed/clipped window)
// - the ImGuiKey enum contains all possible keyboard, mouse and gamepad inputs (e.g. ImGuiKey_A, ImGuiKey_MouseLeft, ImGuiKey_GamepadDpadUp...).
// - before v1.87, we used ImGuiKey to carry native/user indices as defined by each backends. About use of those legacy ImGuiKey values:
// - without IMGUI_DISABLE_OBSOLETE_KEYIO (legacy support): you can still use your legacy native/user indices (< 512) according to how your backend/engine stored them in io.KeysDown[], but need to cast them to ImGuiKey.
// - with IMGUI_DISABLE_OBSOLETE_KEYIO (this is the way forward): any use of ImGuiKey will assert with key < 512. GetKeyIndex() is pass-through and therefore deprecated (gone if IMGUI_DISABLE_OBSOLETE_KEYIO is defined).
IMGUI_APIboolIsKeyDown(ImGuiKeykey);// is key being held.
IMGUI_APIboolIsKeyPressed(ImGuiKeykey,boolrepeat=true);// was key pressed (went from !Down to Down)? if repeat=true, uses io.KeyRepeatDelay / KeyRepeatRate
IMGUI_APIboolIsKeyReleased(ImGuiKeykey);// was key released (went from Down to !Down)?
IMGUI_APIintGetKeyPressedAmount(ImGuiKeykey,floatrepeat_delay,floatrate);// uses provided repeat rate/delay. return a count, most often 0 or 1 but might be >1 if RepeatRate is small enough that DeltaTime > RepeatRate
IMGUI_APIconstchar*GetKeyName(ImGuiKeykey);// [DEBUG] returns English name of the key. Those names a provided for debugging purpose and are not meant to be saved persistently not compared.
IMGUI_APIvoidSetNextFrameWantCaptureKeyboard(boolwant_capture_keyboard);// Override io.WantCaptureKeyboard flag next frame (said flag is left for your application to handle, typically when true it instructs your app to ignore inputs). e.g. force capture keyboard when your widget is being hovered. This is equivalent to setting "io.WantCaptureKeyboard = want_capture_keyboard"; after the next NewFrame() call.
// - To refer to a mouse button, you may use named enums in your code e.g. ImGuiMouseButton_Left, ImGuiMouseButton_Right.
// - You can also use regular integer: it is forever guaranteed that 0=Left, 1=Right, 2=Middle.
// - Dragging operations are only reported after mouse has moved a certain distance away from the initial clicking position (see 'lock_threshold' and 'io.MouseDraggingThreshold')
IMGUI_APIboolIsMouseDown(ImGuiMouseButtonbutton);// is mouse button held?
IMGUI_APIboolIsMouseClicked(ImGuiMouseButtonbutton,boolrepeat=false);// did mouse button clicked? (went from !Down to Down). Same as GetMouseClickedCount() == 1.
IMGUI_APIboolIsMouseReleased(ImGuiMouseButtonbutton);// did mouse button released? (went from Down to !Down)
IMGUI_APIboolIsMouseDoubleClicked(ImGuiMouseButtonbutton);// did mouse button double-clicked? Same as GetMouseClickedCount() == 2. (note that a double-click will also report IsMouseClicked() == true)
IMGUI_APIintGetMouseClickedCount(ImGuiMouseButtonbutton);// return the number of successive mouse-clicks at the time where a click happen (otherwise 0).
IMGUI_APIboolIsMouseHoveringRect(constImVec2&r_min,constImVec2&r_max,boolclip=true);// is mouse hovering given bounding rect (in screen space). clipped by current clipping settings, but disregarding of other consideration of focus/window ordering/popup-block.
IMGUI_APIboolIsMousePosValid(constImVec2*mouse_pos=NULL);// by convention we use (-FLT_MAX,-FLT_MAX) to denote that there is no mouse available
IMGUI_APIboolIsAnyMouseDown();// [WILL OBSOLETE] is any mouse button held? This was designed for backends, but prefer having backend maintain a mask of held mouse buttons, because upcoming input queue system will make this invalid.

// - When ScrollX is off:

// while (clipper.Step())
// for (int i = clipper.DisplayStart; i < clipper.DisplayEnd; i++)

// Generally what happens is:
// - Clipper lets you process the first element (DisplayStart = 0, DisplayEnd = 1) regardless of it being visible or not.
// - User code submit that one element.
// - Clipper can measure the height of the first element
// - Clipper calculate the actual range of elements to display based on the current clipping rectangle, position the cursor before the first visible element.
// - User code submit visible elements.
// - The clipper also handles various subtleties related to keyboard/gamepad navigation, wrapping etc.

// - Mouse cursor shapes for software cursor rendering (unless setting 'Flags |= ImFontAtlasFlags_NoMouseCursors' in the font atlas).
// It is the user-code responsibility to setup/build the atlas, then upload the pixel data into a texture accessible by your graphics api.
// - Optionally, call any of the AddFont*** functions. If you don't call any, the default font embedded in the code will be loaded for you.

// - If you pass a 'glyph_ranges' array to AddFont*** functions, you need to make sure that your array persist up until the

// - Important: By default, AddFontFromMemoryTTF() takes ownership of the data. Even though we are not writing to it, we will free the pointer on destruction.
// You can set font_cfg->FontDataOwnedByAtlas=false to keep ownership of your data and it won't be freed,
// - Even though many functions are suffixed with "TTF", OTF data is supported just as well.
// - This is an old API and it is currently awkward for those and various other reasons! We will address them in the future!
