Render

NewFrame() start a new Dear ImGui frame, you can submit any command from this point until Render()/EndFrame().

EndFrame() ends the Dear ImGui frame. Automatically called by Render(). If you don't need to render data (skipping rendering) you may call EndFrame() without Render()... but you'll have wasted CPU already! If you don't need to render, better to not create any windows and not call NewFrame() at all!

Render() ends the Dear ImGui frame, finalize the draw data.

ImGui:newFrame(deltaTime)
ImGui:render()
ImGui:endFrame()

Demos

is_openFlag = ImGui:showUserGuide()
is_openFlag = ImGui:showDemoWindow([p_open])
is_openFlag = ImGui:showAboutWindow([p_open])
is_openFlag = ImGui:showStyleEditor()
is_openFlag = ImGui:showFontSelector()
is_openFlag = ImGui:showMetricsWindow([p_open])
is_openFlag = ImGui:showStyleSelector(label)
is_openFlag = ImGui:ShowStackToolWindow([p_open])
ImGui:showLuaStyleEditor()

Windows

Begin() = push window to the stack and start appending to it. End() = pop window from the stack.
You may append multiple times to the same window during the same frame.
Passing bool* p_open != NULL shows a window-closing widget in the upper-right corner of the window, which clicking will set the boolean to false when clicked.
Begin() return false to indicate the window is collapsed or fully clipped, so you may early out and omit submitting anything to the window. Always call a matching End() for each Begin() call, regardless of its return value! [Important: due to legacy reason, this is inconsistent with most other functions such as BeginMenu / EndMenu, BeginPopup / EndPopup, etc. where the EndXXX call should only be called if the corresponding BeginXXX function returned true. Begin and BeginChild are the only odd ones out. Will be fixed in a future update.]
Note that the bottom of window stack always contains a window called "Debug".

p_open, draw = ImGui:beginWindow(label, p_open [, ImGui.WindowFlags = 0])
-- do not show "X" button
draw = ImGui:beginWindow(label, nil [, ImGui.WindowFlags = 0])
-- start a window with no borders, no paddings, no rounding and ImGui.WindowFlags_Fullscreen flag
p_open, draw = ImGui:beginFullScreenWindow(label, p_open [, ImGui.WindowFlags = 0]) 
-- do not show "X" button
draw = ImGui:beginFullScreenWindow(label, nil [, ImGui.WindowFlags = 0]) 
ImGui:endWindow()

Child Windows

Use child windows to begin into a self-contained independent scrolling/clipping regions within a host window. Child windows can embed their own child. For each independent axis of size:

== 0.0f -> use remaining host window size
> 0.0f -> fixed size
< 0.0f -> use remaining window size minus abs(size) Each axis can use a different mode, e.g. ImVec2(0,400). BeginChild() returns false to indicate the window is collapsed or fully clipped, so you may early out and omit submitting anything to the window.

Tip
Always call a matching EndChild() for each BeginChild() call, regardless of its return value [as with Begin: this is due to legacy reason and inconsistent with most BeginXXX functions apart from the regular Begin() which behaves like BeginChild().]

ImGui:beginChild(id [, w = 0, h = 0, borderFlag = false, ImGui.WindowFlags = 0])
ImGui:endChild()

Windows Utilities

Current window = the window we are appending into while inside a Begin() / End() block.
Next window = next window we will Begin() into.

Prefer using SetNextXXX functions (before Begin) rather than SetXXX functions (after Begin()).

flag = ImGui:isWindowAppearing()
flag = ImGui:isWindowCollapsed()
flag = ImGui:isWindowFocused([ImGui.FocusedFlags = 0])
flag = ImGui:isWindowHovered([ImGui.HoveredFlags = 0])
x, y = ImGui:getWindowPos()
w, h = ImGui:getWindowSize()
w = ImGui:getWindowWidth()
h = ImGui:getWindowHeight()
x1,y1, x2,y2 = ImGui:getWindowBounds() -- returns window region rectangle in global coordinates

ImGui:setNextWindowPos(x, y [, ImGui.Cond = 0, pivotX = 0, pivotY = 0])
ImGui:setNextWindowSize(w, h [, ImGui.Cond = 0])
ImGui:setNextWindowContentSize(w, h)
ImGui:setNextWindowCollapsed(flag [, ImGui.Cond = 0])
ImGui:setNextWindowFocus()
ImGui:setNextWindowBgAlpha(alpha)
ImGui:setNextWindowScroll(x, y)
ImGui:setWindowPos(name, x, y [, ImGui.Cond = 0]) OR ImGui:setWindowPos(x, y [, ImGui.Cond = 0])
ImGui:setWindowSize(name, w, h [, ImGui.Cond = 0]) OR ImGui:setWindowSize(w, h [, ImGui.Cond = 0])
ImGui:setWindowCollapsed(name, flag [, ImGui.Cond = 0]) OR ImGui:setWindowCollapsed(flag [, ImGui.Cond = 0])
ImGui:setWindowFocus(name) OR ImGui:setWindowFocus()
ImGui:setWindowFontScale(scale)
-- scroll window when touching void
ImGui:scrollWhenDragging(x, y)

Window size constraints

Can be used to set minimum and maximum window size, plus contraint the size if needed.

-- call this function before ImGui:beginWindow()
ImGui:setNextWindowSizeConstraints(min_w, min_h, max_w, max_h [, resize_callback, user_data]))
-- resizeCallback is a function:
function (callbackData [, user_data])
	-- do some math, and return desired size
	-- ...
	return desired_width, desired_height
end

Resize callback:

-- get window position
x, y = callbackData:getPos()
x = callbackData:getX()
y = callbackData:getY()

-- get currrent size
current_width, current_height = callbackData:getCurrentSize()
current_width = callbackData:getCurrentWidth()
current_height = callbackData:getCurrentHeight()

-- get desired size
desired_width, desired_height = callbackData:getDesiredSize()
desired_width = callbackData:getDesiredWidth()
desired_height = callbackData:getDesiredHeight()

Example:

require "ImGui"

local function stepSize(callback_data, step)
	local w, h = callback_data:getDesiredSize()
	w = (w // step) * step
	h = (h // step) * step
	return w, h
end

local ui = ImGui.new()
stage:addChild(ui)

stage:addEventListener("enterFrame", function(e)
	ui:newFrame(e.deltaTime)
	
	-- window size step is 32 (last argument, that is passed to the callback as second argument)
	ui:setNextWindowSizeConstraints(200, 200, 400, 400, stepSize, 32)
	if (ui:beginWindow("My window")) then 
		
		ui:textWrapped("Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.")
	end
	ui:endWindow()
	
	ui:showDemoWindow()
	
	ui:render()
	ui:endFrame()
end)

Content region

Those functions are bound to be redesigned soon (they are confusing, incomplete and return values in local window coordinates which increases confusion)

scaleX, scaleY = ImGui:getContentRegionMax()
w, h = ImGui:getContentRegionAvail()
x, y = ImGui:getWindowContentRegionMin()
x, y = ImGui:getWindowContentRegionMax()

Windows Scrolling

x = ImGui:getScrollX()
y = ImGui:getScrollY()
maxX = ImGui:getScrollMaxX()
maxY = ImGui:getScrollMaxY()
ImGui:setScrollX(value)
ImGui:setScrollY(value)
ImGui:setScrollHereX([ratio = 0.5])
ImGui:setScrollHereY([ratio = 0.5])
ImGui:setScrollFromPosX(x [, ratio = 0.5])
ImGui:setScrollFromPosY(y [, ratio = 0.5])

Parameters stacks (shared)

ImGui:pushStyleColor(ImGui.Col, color, alpha)
ImGui:popStyleColor([count = 1])
ImGui:pushStyleVar(ImGui.StyleVar, value) OR ImGui:pushStyleVar(ImGui.StyleVar, value1, value2)
ImGui:popStyleVar([count = 1])
color, alpha = ImGui:getStyleColor(ImGui.Col)
fontSize = ImGui:getFontSize()

Parameters stacks (current window)

ImGui:pushItemWidth(w)
ImGui:popItemWidth()
ImGui:setNextItemWidth(w)
w = ImGui:calcItemWidth()
ImGui:pushTextWrapPos([localX = 0])
ImGui:popTextWrapPos()
ImGui:pushTabStop(flag)
ImGui:popTabStop()
ImGui:pushButtonRepeat(flag)
ImGui:popButtonRepeat()

Cursor / Layout

By "cursor" we mean the current output position.
The typical widget behavior is to output themselves at the current cursor position, then move the cursor one line down.
You can call SameLine() between widgets to undo the last carriage return and output at the right of the preceeding widget.
Attention! We currently have inconsistencies between window-local and absolute positions we will aim to fix with future API: Window-local coordinates: SameLine(), GetCursorPos(), SetCursorPos(), GetCursorStartPos(), GetContentRegionMax(), GetWindowContentRegion*(), PushTextWrapPos() Absolute coordinate: GetCursorScreenPos(), SetCursorScreenPos(), all ImDrawList:: functions.

ImGui:separator()
ImGui:sameLine([offset_x = 0, spacing = -1])
ImGui:newLine()
ImGui:spacing()
ImGui:dummy(w, h)
ImGui:indent([indent = 0])
ImGui:unindent([indent = 0])
ImGui:beginGroup()
ImGui:endGroup()
 
x, y = ImGui:getCursorPos()
x = ImGui:getCursorPosX()
y = ImGui:getCursorPosY()
ImGui:setCursorPos(local_x, local_y)
ImGui:setCursorPosX(local_x)
ImGui:setCursorPosY(local_y)
x, y = ImGui:getCursorStartPos()
x, y = ImGui:getCursorScreenPos()
ImGui:setCursorScreenPos(x, y)
ImGui:alignTextToFramePadding()
lineH = ImGui:getTextLineHeight()
lineH = ImGui:getTextLineHeightWithSpacing()
frameH = ImGui:getFrameHeight()
frameH = ImGui:getFrameHeightWithSpacing()

ID stack/scopes

Read the FAQ for more details about how ID are handled in Dear Imgui. 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.
The resulting ID are hashes of the entire stack.
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 and used as an ID, whereas "str_id" denote a string that is only used as an ID and not normally displayed.

ImGui:pushID(anyValue) 
ImGui:pushID(str)
ImGui:popID()
number = ImGui:getID(anyValue)
number = ImGui:getID(str)
number = ImGui:getItemID()

ImGui:listBoxFooter()

Widgets: Data Plotting

Caching:

If you have big array of points it is better to cache it instead of translating lua table to C++ vector every time you call `ImGui:plotLines()`. But in this case you need to manage memory by yourself (free points pointer when you dont need it).

-- store points in memory
-- points_table: {0.01, 0.5, 10, -50, ...}
-- ptr: c++ pointer to a given vector
ptr = ImGui.cachePoints(points_table)

-- delete points from memory
ImGui.freePoints(ptr)

Plot functions:

-- len (number): points array length
ImGui:plotCachedLines(label, ptr, len,
	[, values_offset = 0, overlay_text = nil,
	scale_min = math.huge, scale_max = math.huge,
	w = 0, h = 0])

ImGui:plotCachedHistogram(label, ptr, len,
	[, values_offset = 0, overlay_text = nil,
	scale_min = math.huge, scale_max = math.huge,
	w = 0, h = 0])

ImGui:plotLines(label, points_table
	[, values_offset = 0, overlay_text = nil,
	scale_min = math.huge, scale_max = math.huge,
	w = 0, h = 0])

ImGui:plotHistogram(label, points_table
	[, values_offset = 0, overlay_text = nil,
	scale_min = math.huge, scale_max = math.huge,
	w = 0, h = 0])

Example:

-- delete ptr if it exist
function deletePtr()
	if pointsPtr then
		ImGui.freePoints(pointsPtr)
	end
end

function onEnterFrame()
	ui:newFrame(e.deltaTime)
	
	if ui:button("Generate") then
		deletePtr()
		points = generatePoints() -- returns big array
		pointsPtr = ImGui.cachePoints(points)
	end
	
	if pointsPtr then
		ui:plotCachedLines("Big data", pointsPtr, #points)
	end
	
	ui:render()
	ui:endFrame()
end

-- do not forget to clear memory when app is closing
function onAppExit()
	deletePtr()
end

Widgets: Value() Helpers

ImGui:value(prefix, bool)
ImGui:value(prefix, number)
ImGui:value(prefix, float, format_string)

Widgets: Menus

result? = ImGui:beginMenuBar()
ImGui:endMenuBar()
result? = ImGui:beginMainMenuBar()
ImGui:endMainMenuBar()
result = ImGui:beginMenu(label [, enabled = true])
result = ImGui:beginMenuEx(label, [icon = "", enabled = true])
ImGui:endMenu()
result = ImGui:menuItem(label [, shortcut = "", selected = false, enabled = true])
result = ImGui:menuItemEx(label, [icon = "", shortcut = "", selected = false, enabled = true])

Widgets: Tooltips

Tooltip are windows following the mouse which do not take focus away.

ImGui:beginTooltip()
ImGui:endTooltip()
ImGui:setTooltip(text)

Disabled groups

ImGui:beginDisabled(disabledFlag)
ImGui:endDisabled()

Popups, Modals

The properties of popups windows are: - They block normal mouse hovering detection outside them. (*1) - Unless modal, they can be closed by clicking anywhere outside them, or by pressing ESCAPE. Because hovering detection is disabled outside the popup, when clicking outside the click will not be seen by underlying widgets! (*1)

Their visibility state (~bool) is held internally by Dear ImGui instead of being held by the programmer as we are used to with regular Begin() calls. User can manipulate the visibility state by calling OpenPopup(), CloseCurrentPopup() etc.
We default to use the right mouse (ImGuiMouseButton_Right=1) for the Popup Context functions.
Those three properties are connected: we need to retain popup visibility state in the library because popups may be closed as any time.

(1.) You can bypass that restriction and detect hovering even when normally blocked by a popup. To do this use the ImGuiHoveredFlags_AllowWhenBlockedByPopup when calling IsItemHovered() or IsWindowHovered(). This is what BeginPopupContextItem() and BeginPopupContextWindow() are doing already, allowing a right-click to reopen another popups without losing the click.

result? = ImGui:beginPopup(str_id [, ImGui.WindowFlags = 0])
p_open, result? = ImGui:beginPopupModal(str_id, p_open [, ImGui.WindowFlags = 0])
ImGui:endPopup()
ImGui:openPopup(str_id [, ImGui.PopupFlags = 0])
ImGui:openPopupOnItemClick(str_id [, ImGui.PopupFlags = 0])
ImGui:closeCurrentPopup()
result? = ImGui:beginPopupContextItem(str_id [, ImGui.PopupFlags = 0])
result? = ImGui:beginPopupContextWindow(str_id [, ImGui.PopupFlags = 0])
result? = ImGui:beginPopupContextVoid(str_id [, ImGui.PopupFlags = 0])
result? = ImGui:isPopupOpen(str_id [, ImGui.PopupFlags = 0])

Columns

You can also use SameLine(pos_x) to mimic simplified columns.
The columns API is work-in-progress and rather lacking (columns are arguably the worst part of dear imgui at the moment!)
There is a maximum of 64 columns.
Currently working on new 'Tables' api which will replace columns around Q2 2020 (see GitHub #2957).

ImGui:columns([count = 1, id = nil, border = true])
ImGui:nextColumn()
index = ImGui:getColumnIndex()
width = ImGui:getColumnWidth([column_index = -1])
ImGui:setColumnWidth(column_index, width)
offset = ImGui:getColumnOffset([column_index = -1])
ImGui:setColumnOffset(column_index, offset)
number = ImGui:getColumnsCount()

Tab Bars, Tabs

bool = ImGui:beginTabBar(str_id [, ImGui.TabBarFlags = 0])
ImGui:endTabBar()
p_open, bool = ImGui:beginTabItem(label, p_open [, ImGui.TabItemFlags = 0])
ImGui:endTabItem()
ImGui:setTabItemClosed(tab_or_docked_window_label)
ImGui:tabItemButton(label [, ImGui.TabItemFlags = 0])

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:logToTTY(auto_open_depth = -1) 
ImGui:logToFile(auto_open_depth = -1, filename = nil) 
ImGui:logToClipboard(auto_open_depth = -1) 
ImGui:logFinish() 
ImGui:logButtons() 
ImGui:logText(text)

Drag and drop

flag = ImGui:beginDragDropSource([ImGui.DragDropFlags flags = 0])
flag = ImGui:setNumDragDropPayload(str_type, number [, ImGui.Cond cond = 0])
flag = ImGui:setStrDragDropPayload(str_type, string [, ImGui.Cond cond = 0])
ImGui:endDragDropSource()
flag = ImGui:beginDragDropTarget()
ImGuiPayload = ImGui:acceptDragDropPayload(type [, ImGui.DragDropFlags flags = 0])
ImGui:endDragDropTarget()
ImGuiPayload = ImGui:getDragDropPayload()

Payload:

number = ImGuiPayload:getNumData()
string = ImGuiPayload:getStrData()
ImGuiPayload:clear()
number = ImGuiPayload:getDataSize()
flag = ImGuiPayload:isDataType(type) -- type must be the same as in "ImGui:acceptDragDropPayload(type)"
flag = ImGuiPayload:isPreview()
flag = ImGuiPayload:isDelivery()

Usage example:

require "ImGui"

local imgui = ImGui.new()
stage:addChild(imgui)

local names = {
	"Bobby", "Beatrice", "Betty",
	"Brianna", "Barry", "Bernard",
	"Bibi", "Blaine", "Bryn"
}
-- modes:
local Mode_Copy = 0
local Mode_Move = 1
local Mode_Swap = 2
 
local mode = 0 -- current mode

function onEnterFrame(e)
	imgui:newFrame(e.deltaTime)
 
	if (imgui:radioButton("Copy", mode == Mode_Copy)) then mode = Mode_Copy end imgui:sameLine()
	if (imgui:radioButton("Move", mode == Mode_Move)) then mode = Mode_Move end imgui:sameLine()
	if (imgui:radioButton("Swap", mode == Mode_Swap)) then mode = Mode_Swap end
 
	for i,v in ipairs(names) do
		imgui:pushID(i)
		if (((i-1) % 3) ~= 0) then imgui:sameLine() end
 
		imgui:button(v, 60, 60)

			--imgui:setStrDragDropPayload("DND_DEMO_CELL", "ID_"..i) -- used for strings
			imgui:setNumDragDropPayload("DND_DEMO_CELL", i) -- used for numbers
 
			if (mode == Mode_Copy) then imgui:text(("Copy %s"):format(v)) end
			if (mode == Mode_Move) then imgui:text(("Move %s"):format(v)) end
			if (mode == Mode_Swap) then imgui:text(("Swap %s"):format(v)) end
			imgui:endDragDropSource()
		end
 
		if (imgui:beginDragDropTarget()) then
			local payload = imgui:acceptDragDropPayload("DND_DEMO_CELL")
			if (payload) then
				--local payload_n = tonumber(payload:getStrData():sub(4))  -- if "setStrDragDropPayload" was used
				local payload_n = payload:getNumData() -- if "setNumDragDropPayload" was used
 
				if (mode == Mode_Copy) then
					names[i] = names[payload_n];
				end
				if (mode == Mode_Move) then
					names[i] = names[payload_n];
					names[payload_n] = "";
				end
 
				if (mode == Mode_Swap) then
					names[i], names[payload_n] = names[payload_n], names[i]
				end
			end
			imgui:endDragDropTarget()
		end
		imgui:popID()
	end
	imgui:render()
	imgui:endFrame()
end

Clipping

ImGui:pushClipRect(min_x, min_y, max_x, max_y, intersect_with_current_clip_rect)
ImGui:popClipRect()

ImGuiListClipper

Try to avoid creating new instances in "enterFrame" event.

Constructor:

instance = ImGuiListClipper.new()

Methods:

ImGuiListClipper:beginClip(number_of_items [, item_height = -1]) -- if item_height <= 0 then it is calculated automatically
ImGuiListClipper:endClip()
bool = ImGuiListClipper:step()
number = ImGuiListClipper:getDisplayStart()
number = ImGuiListClipper:getDisplayEnd()
number = ImGuiListClipper:getStartPosY()
number = ImGuiListClipper:getItemsCount()
ImGuiListClipper:forceDisplayRangeByIndices(number_min, number_max)

Usage example:

require "ImGui"

local imgui = ImGui.new()
stage:addChild(imgui)

clipper = ImGuiListClipper.new()

function onEnterFrame(e)
	imgui:newFrame(e.deltaTime)

	if (imgui:beginWindow("Clipper demo")) then
		if (imgui:beginTable("table", 3)) then
			imgui:tableSetupScrollFreeze(0, 1) -- cols, rows
			imgui:tableSetupColumn("One")
			imgui:tableSetupColumn("Two")
			imgui:tableSetupColumn("Three")
			imgui:tableHeadersRow()

			clipper:beginClip(100)
			while (clipper:step()) do
				for row = clipper:getDisplayStart(), clipper:getDisplayEnd() do
					imgui:tableNextRow()
					for column = 1, 3 do
						imgui:tableSetColumnIndex(column - 1)
						imgui:text(("col: %d; row: %d"):format(column, row))
					end
				end
			end
			clipper:endClip()

number = ImGui:getTime()
number = ImGui:getFrameCount()
str = ImGui:getStyleColorName(idx)
flag = ImGui:beginChildFrame(id, w, h [, ImGui.WindowFlags = 0]) -- id (number)
ImGui:endChildFrame()

Text Utilities

w, h = ImGui:calcTextSize(text [, hide_text_after_double_hash = false, wrap_width = -1])

Color convert

Note: use DOT instead of COLON, so you can use it without creating an ImGui object

r, g, b, a = ImGui.colorConvertHEXtoRGB(color [, alpha = 1])
hex = ImGui.colorConvertRGBtoHEX(r, g, b)
h, s, v = ImGui.colorConvertRGBtoHSV(r, g, b)
r, g, b = ImGui.colorConvertHSVtoRGB(h, s, v)
h, s, v = ImGui.colorConvertHEXtoHSV(hex)
hex = ImGui.colorConvertHSVtoHEX(h, s, v)

Inputs Utilities: Keyboard

For 'int user_key_index' you can use your own indices/enums according to how your backend/engine stored them in io.KeysDown[].
We don't know the meaning of those value. You can use GetKeyIndex() to map a ImGuiKey_ value into the user index.

string = ImGui:getKeyName(keyCode)
flag = ImGui:isKeyDown(keyCode)
flag = ImGui:isKeyPressed(keyCode [, repeat = true])
flag = ImGui:isKeyReleased(keyCode)
number = ImGui:getKeyPressedAmount(keyCode, repeat_delay, rate)
ImGui:setNextFrameWantCaptureKeyboard([want_capture_keyboard_value = true])

Shortcut system

-- (keyChord: an ImGuiKey optionally OR-ed with one or more ImGuiMod_XXX values (ImGuiKey | ImGuiMod_XXX))
ImGui:shortcut(keyChord [, owner_id = 0, ImGui.InputFlags = 0])

-- (useful to disable CTRL + TAB combo: ImGui:setShortcutRouting(ImGui.Mod_Ctrl | ImGui.Key_Tab, ImGui.KeyOwner_None))
ImGui:setShortcutRouting(keyChord [, owner_id = 0, ImGui.InputFlags = 0])

ImGui:setItemKeyOwner(keyCode [, ImGui.InputFlags = 0])

ImGui:setKeyOwner(keyCode, owner_id, [, ImGui.InputFlags = 0])

Inputs Utilities: Mouse

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')

-- "mouse_button" is any gideros mouse button code

ImGuiTextFilter

Try to avoid creating new instaces in "enterFrame" event.

Constructor:

filter = ImGuiTextFilter.new()

Methods:

-- draws the input field
isValueChanged = filter:draw(label [, width = 0])
-- draws the input field (using ImGui:inutTextWithHint())
isValueChanged = filter:drawWithHint(label, hint [, width = 0])

filter:setBuffer(text) -- set filter text
filter:build() -- update filter internals (see example below)
bool = filter:passFilter(text) -- returns true if filter input matches with "text"

Usage example 1:

require "ImGui"

local imgui = ImGui.new()
stage:addChild(imgui)

local filter = ImGuiTextFilter.new()
local items = { "aaa1.c", "bbb1.c", "ccc1.c", "aaa2.cpp", "bbb2.cpp", "ccc2.cpp", "abc.h", "hello, world" }

function onEnterFrame(e)
	imgui:newFrame(e.deltaTime)

	if (imgui:beginWindow("Filter demo")) then
		imgui:text([[
Filter usage:
	""         display all lines
	"xxx"      display lines containing "xxx"
	"xxx,yyy"  display lines containing "xxx" or "yyy"
	"-xxx"     hide lines containing "xxx"
		]])

		filter:draw("Filter")

		for i, text in ipairs(items) do
			if filter:passFilter(text) then
				imgui:bulletText(text)
			end
		end
	end
	imgui:endWindow()

	imgui:endFrame()
	imgui:render()
end

stage:addEventListener("enterFrame", onEnterFrame)

Usage example 2:

require "ImGui"

local imgui = ImGui.new()
stage:addChild(imgui)

local filter = ImGuiTextFilter.new()
local searchText = ""
local items = { "aaa1.c", "bbb1.c", "ccc1.c", "aaa2.cpp", "bbb2.cpp", "ccc2.cpp", "abc.h", "hello, world" }

	-- draw custom control
	local ischanged = false
	searchText, ischanged = imgui:inputText("Filter", searchText, 256, ImGui.InputTextFlags_EnterReturnsTrue)
	if ischanged then
		filter:setBuffer(searchText)
		-- try to avoid calling "build" function every frame
		filter:build()
	end

	for i, item in ipairs(items) do
		if not filter:passFilter(item) then

+== Windows ==
+* Begin() = push window to the stack and start appending to it. End() = pop window from the stack.
+* You may append multiple times to the same window during the same frame.
+* Passing bool* p_open != NULL shows a window-closing widget in the upper-right corner of the window, which clicking will set the boolean to false when clicked.
+* Begin() return false to indicate the window is collapsed or fully clipped, so you may early out and omit submitting anything to the window. Always call a matching End() for each Begin() call, regardless of its return value! [Important: due to legacy reason, this is inconsistent with most other functions such as BeginMenu / EndMenu, BeginPopup / EndPopup, etc. where the EndXXX call should only be called if the corresponding BeginXXX function returned true. Begin and BeginChild are the only odd ones out. Will be fixed in a future update.]
+* Note that the bottom of window stack always contains a window called "Debug".

-== Style setters/getters ==
+=== Child Windows ===
-Get style settings instance:
+Use child windows to begin into a self-contained independent scrolling/clipping regions within a host window. Child windows can embed their own child. For each independent axis of size:
+* == 0.0f -> use remaining host window size
+* > 0.0f -> fixed size
+* < 0.0f -> use remaining window size minus abs(size) Each axis can use a different mode, e.g. ImVec2(0,400). BeginChild() returns false to indicate the window is collapsed or fully clipped, so you may early out and omit submitting anything to the window.
+ '''Tip'''
+ Always call a matching EndChild() for each BeginChild() call, regardless of its return value [as with Begin: this is due to legacy reason and inconsistent with most BeginXXX functions apart from the regular Begin() which behaves like BeginChild().]

+== Cursor / Layout ==
+* By "cursor" we mean the current output position.
+* The typical widget behavior is to output themselves at the current cursor position, then move the cursor one line down.
+* You can call SameLine() between widgets to undo the last carriage return and output at the right of the preceeding widget.
+* '''Attention'''! We currently have inconsistencies between window-local and absolute positions we will aim to fix with future API: Window-local coordinates: SameLine(), GetCursorPos(), SetCursorPos(), GetCursorStartPos(), GetContentRegionMax(), GetWindowContentRegion*(), PushTextWrapPos() Absolute coordinate: GetCursorScreenPos(), SetCursorScreenPos(), all ImDrawList:: functions.

+The properties of popups windows are: - They block normal mouse hovering detection outside them. (*1) - Unless modal, they can be closed by clicking anywhere outside them, or by pressing ESCAPE. Because hovering detection is disabled outside the popup, when clicking outside the click will not be seen by underlying widgets! (*'''1''')
-callback_data:setBuf(string)
+* Their visibility state (~bool) is held internally by Dear ImGui instead of being held by the programmer as we are used to with regular Begin() calls. User can manipulate the visibility state by calling OpenPopup(), CloseCurrentPopup() etc.
+* We default to use the right mouse (ImGuiMouseButton_Right=1) for the Popup Context functions.
+* Those three properties are connected: we need to retain popup visibility state in the library because popups may be closed as any time.

+('''1'''.) You can bypass that restriction and detect hovering even when normally blocked by a popup. To do this use the ImGuiHoveredFlags_AllowWhenBlockedByPopup when calling IsItemHovered() or IsWindowHovered(). This is what BeginPopupContextItem() and BeginPopupContextWindow() are doing already, allowing a right-click to reopen another popups without losing the click.
