Tutorial on the Lotion User Interface Classes5.2 The lotion main.cpp fileThis section describes the logic flow in the main.cpp file:• Includes and enumerations in main.cpp• Convenience functions on page 5-11• Evaluating the start-up arguments on page 5-12• Initializing the applets on page 5-15• Starting the application on page 5-17.5.2.1 Includes and enumerations in main.cppThe main.cpp file starts with include statements and enumerations as shown in Example 5-1:Example 5-1 Includes and enumerations in main.cpp#include #include #include #include #ifdef MDE_OS_WIN32#include #else#include #endif#include #include "lotion.h"#include "applets/lightshow/lightshow.h"#include "applets/browser/browser.h"#include "applets/slideshow_presentation/slideshow_presentation.h"enum applets {APPLET_PHOTO_BROWSER = 1
Tutorial on the Lotion User Interface Classes5.2.2 Convenience functionsSome convenience functions are defined as shown in Example 5-2:Example 5-2 Convenience functionsstatic void cdToExecutable() {char buf[PATH_MAX + 1];#ifdef MDE_OS_WIN32if(GetModuleFileName(GetModuleHandle(NULL), buf, sizeof(buf)) == 0){MDE_GENERAL_ERROR("Can not find location of executing application");}char * enddir = strrchr(buf, '\\');#elseif (readlink("/proc/self/exe", buf, sizeof(buf) - 1) == -1){MDE_GENERAL_ERROR("Can not find location of executing application");}char * enddir = strrchr(buf, '/');#endif*enddir = 0;chdir(buf);}static void errorExit(const char * fmt, const char * arg){printf(fmt, arg);#ifdef MDE_OS_WIN32// Pause so that we don't lose the message on exit.printf("Press RETURN to exit ...");getchar();#endifexit(-1);}static void printHelp() {printf("SYNTAX: lotion [-resolution arg] [-depth arg] [-theme arg] [-applets args] [-input args]\n\n");printf("-resolution\n");printf(" 800x480\n");printf(" 800x600\n\n");printf("-depth\n");printf(" bits per pixel\n\n");printf("-theme\n");printf(" blue\n");printf(" robot\n");printf(" minimal\n");printf("-applets\n");printf(" all\n");printf(" default (all)\n");printf(" lightshow\n");printf(" planet\n");printf(" buzzword\n");printf(" photo\n");printf(" presentation\n");printf(" slideshow\n");printf(" browser\n\n");ARM DUI 0527A-02a Copyright © 2010 ARM.
