Tutorial on the Lotion <strong>User</strong> <strong>Interface</strong> Classes5.3 The application.cpp fileThe application.cpp file contains the code that implements the <strong>Application</strong> class:1. The application.h header file contains the <strong>Application</strong> class definition. SeeExample 5-15:Example 5-14 <strong>Application</strong> header fileclass <strong>Application</strong>{Theme* currentTheme;MDE::System* system;MDE::Context* context;MDE::FileSystem* fileSystem;MDE::Proxy* proxy;MDE::Timer* timer;MDE::Array mtDevices;MDE::vec2i resolution;Render<strong>Engine</strong>* render<strong>Engine</strong>;MultiTouch::Device* calibratingDevice;MDE::vec4i viewport;bool nativeResolution;};public:<strong>Application</strong>();Render<strong>Engine</strong>* getRender<strong>Engine</strong>();MDE::Context* getContext();MDE::System* getSystem();void setResolution(MDE::vec2i resolution);void addMultiTouchDevice(MultiTouch::Device* mtDevice);void setup(Theme* theme);void run();void runApplet(Applet* applet);MDE::Proxy* getProxy();Theme* getTheme();float getTime();void resetViewport();2. The constructor assigns values for the viewing area. See Example 5-15:Example 5-15 <strong>Application</strong> constructor<strong>Application</strong>::<strong>Application</strong>(){nativeResolution = true;viewport = MDE::vec4i(0, 0, WINDOW_WIDTH, WINDOW_HEIGHT);resolution = MDE::vec2i(WINDOW_WIDTH, WINDOW_HEIGHT);calibratingDevice = 0;}The constants WINDOW_HEIGHT and WINDOW_WIDTH are 480 and 8003. Initialization code in main.cpp calls the setup methods. See Example 5-16 on page 5-20:ARM DUI 0527A-02a Copyright © 2010 ARM. All rights reserved. 5-19ID070710Non-Confidential - Draft - Beta
