Here you will find various resources to help you create GUI with Dear ImGui in Gideros Studio.
note: you may have to provide your own assets (fonts, gfx, …).
ImGui Centered Text & Colored Text
Here we center our text and introduce some more functionalities
require "ImGui"
local imgui = ImGui.new()
stage:addChild(imgui)
-- some imgui params
local IO = imgui:getIO()
IO:setFontGlobalScale(2.5)
--imgui:setLightStyle()
--imgui:setClassicStyle()
-- some vars
local xtext, xtext2 = "Centered Text", "Colored Text"
-- the loop
function enterFrame(e)
local CW = application:getContentWidth()
-- 1 begin
imgui:newFrame(e)
-- 2 our GUI
if (imgui:beginFullScreenWindow("Hello ImGui", nil)) then
-- some spacing
imgui:dummy(CW, 32 * 2) -- imgui:dummy(w, h)
-- a centered text
local textW = imgui:calcTextSize(xtext)
local textMid = (CW - textW) / 2
imgui:dummy(textMid, 0)
imgui:sameLine(0, 0) -- puts the next element on the same line with no gap, for gaps use imgui:sameLine()
imgui:text(xtext)
-- some spacing
imgui:dummy(CW, 32 * 4)
-- a colored text
imgui:textColored(xtext2, 0xff00ff)
imgui:endWindow()
-- 3 end
end
imgui:endFrame()
imgui:render()
end
-- the listeners
stage:addEventListener("enterFrame", enterFrame)
ImGui Buttons
Here we make some buttons
require "ImGui"
-- Setup ImGui
local imgui = ImGui.new()
stage:addChild(imgui)
-- some imgui params
local IO = imgui:getIO()
IO:setFontGlobalScale(2.5)
imgui:setClassicStyle()
stage:addChild(imgui)
-- some vars
local xtext = "Centered Text"
-- image to draw
local imageTex = Texture.new("gfx/image.jpg")
function enterFrame(e)
-- 1 begin
imgui:newFrame(e)
local CW = application:getContentWidth()
-- 2 our GUI
if (imgui:beginFullScreenWindow("Hello ImGui", nil)) then
-- some spacing
imgui:dummy(CW, 32 * 2)
-- a centered text?
local textW = imgui:calcTextSize(xtext)
local textMid = (CW - textW) / 2
imgui:dummy(textMid, 0)
imgui:sameLine(0, 0)
imgui:text(xtext)
-- some spacing
imgui:dummy(CW, 32 * 2)
-- a button
imgui:text("A button")
imgui:pushStyleVar(ImGui.StyleVar_ButtonTextAlign, 0.5, 0.5)
imgui:button(("x"), 128, 64) -- text, w, h
imgui:popStyleVar()
-- some spacing
imgui:dummy(CW, 32 * 1)
-- a grid of buttons
imgui:text("A grid of buttons")
local i = 0
for x = 0,1,0.5 do
for y = 0,1,0.5 do
imgui:pushStyleVar(ImGui.StyleVar_ButtonTextAlign, x, y)
if(imgui:button(("[%.1f, %.1f]"):format(x,y), application:getContentWidth() / 3, 100)) then
print(x, y)
end
imgui:popStyleVar()
-- count elements
i += 1
-- make new line on 3d element
if (i % 3 ~= 0) then imgui:sameLine() end
end
end
-- some spacing
imgui:dummy(application:getContentWidth(), 32 * 1)
-- an image button with text
imgui:text("An image button \nwith text")
if(imgui:imageButtonWithText(imageTex, "button", 16, 16)) then
print("pressed")
end
end
imgui:endWindow()
-- 3 end
imgui:endFrame()
imgui:render()
end
-- add listener to draw GUI
stage:addEventListener("enterFrame", enterFrame)
