how to integrate imguix

• all you need are Classes/imgui folder

• create GLView:

// include headers
#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32) || (CC_TARGET_PLATFORM == CC_PLATFORM_MAC)
	#include "CCIMGUIGLViewImpl.h"
	#include "CCImGuiLayer.h"
#endif

// create glview
director->setOpenGLView(IMGUIGLViewImpl::createWithRect("imguix", Rect(0, 0, width,   height)));

// add imgui layer on the top
#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32) || (CC_TARGET_PLATFORM == CC_PLATFORM_MAC)
	// ImGui is always on the top
	Director::getInstance()->getScheduler()->schedule([](float) {
		if (!Director::getInstance()->getRunningScene()->getChildByName("ImGUILayer")) {
			Director::getInstance()->getRunningScene()->addChild(ImGuiLayer::create(), INT_MAX,   "ImGUILayer");
		}
	}, this, 0, false, "checkImGUI");
#endif

how to use

// add ui
CCIMGUI::getInstance()->addImGUI([=](){
	{
	   ImGui::Text("Hello, world!");
   }
}, "demoid");

// remove ui
CCIMGUI::getInstance()->removeImGUI("demoid");

// create button with file name, auto pushID / popID with texture id
CCIMGUI::getInstance()->imageButton("filename.png");

// create button with SpriteFrameName, auto pushID / popID with texture id
CCIMGUI::getInstance()->imageButton("#framename");

// chinese font
// http://www.slackware.com/~alien/slackbuilds/wqy-zenhei-font-ttf/build/wqy-zenhei-0.4.23-1.tar.gz
ImGuiIO &io = ImGui::GetIO();
io.Fonts->AddFontFromFileTTF("res/wqy-zenhei.ttf", 18.0f, 0, io.Fonts->GetGlyphRangesChinese());

lua binding

1. ImGui::ImageButton -> imgui.imageButton

-- text
imgui.text("Hello, World!")

-- text button
imgui.button("text button")

-- new window
if imgui.begin("Toolbar") then
end

-- input text
buf = "input"
ret, buf = imgui.inputText("input", buf, 256)

-- slider
float = 3
ret, float = imgui.sliderFloat("float", float, 0, 8)

-- image button

-- create with image file name
if imgui.imageButton("res/1.png") then print("image button click 1") end
-- or create with sprite frame name
if imgui.imageButton("#CoinSpin01.png") then print("CoinSpin01 1") end
