Returns: (bool) whether the window is collapsed or expanded
Example
require "ImGui"
local imgui = ImGui.new()
stage:addChild(imgui)
local window01 = true -- the starting state of window01, true=window is visible at start up
local window02 = true -- the starting state of window02, true=window is visible at start up
local window03 = true -- the starting state of window03, true=window is visible at start up
function onEnterFrame(e)
-- 1 we start ImGui
imgui:newFrame(e.deltaTime)
-- 2 we add a child window and build our GUI
if window01 then -- is window visible (not closed)?
local windowdrawn = false -- is window expanded or colapsed?
window01, windowdrawn = imgui:beginWindow( -- with close button
"Hello ImGui v"..ImGui._VERSION, -- window title
window01 -- returns window visibility
)
if windowdrawn then -- the variable is false when main window is collapsed
imgui:text("This is an ImGui text.") -- we add a text element to our GUI
imgui:textColored("This is a colored text.", 0xff00ff, 1)
-- ...
end
end
window02 = imgui:beginWindow("Window02") -- no close button
if window02 then -- is window expanded or colapsed?
imgui:text("I am a text in window02")
print(e.deltaTime) -- test
-- ...
end
window03 = imgui:beginWindow(
0, -- dummy title because we set the window with no title bar
nil, -- no close button
ImGui.WindowFlags_NoTitleBar -- no title bar
)
if window03 then -- is window expanded or colapsed?
imgui:text("This is an ImGui text.") -- we add a text element to our GUI
imgui:textColored("This is a colored text.", 0xff00ff, 1)
-- ...
end
-- 3 we end the frame and render to screen
imgui:endFrame()
imgui:render()
end
